Rhepanol® fk – advantages One, two, three, sealed!

Application is incredibly easy and safe: Roll out Rhepanol fk, clean the seam area, pull off the protective strip and press down the edge – sealed! The same goes for all preformed details, which are also equipped with the unique selfsealing edge system.

The roofing membrane with a strong character Tried and tested long-term reliability, over 50 years of experience with polyisobutylene The oldest synthetic roofing membrane made in Germany With a unique self-sealing edge for reliable and fast sealing of seams Fleece backing with extremely high tensile strength Made of polyisobutylene (PIB), therefore compatible with bitumen One roofing membrane for all application methods The only roofing membrane to be applied with the Gripfix system Resistant to UV-radiation Flexible at temperatures as low as – 60 °C Free of plasticizers and halogen-containing fireproofing agents Application without open flame No need for surface protection Comprehensive warranty on materials Ideal for refurbishment

Factory applied self-sealing edge for reliable and fast sealing of seams.

The self-sealing edge system The pre-fabricated self-sealing edge system is different from conventional adhesive bonding. Sealing of the seams is carried out by firmly joining homogenous materials. Immediately after the self-sealing edge has been pressed to the connecting membrane the seam is already waterproof. Owing to the integrated selfsealing edge, seams can be sealed without open flame, hot air, solvent welding or additional adhesives, making application more efficient and almost independent of weather conditions.

... roll out It only takes three steps: Rhepanol fk with self-sealing edge system.

... clean the seam, pull off the protective strip

Rhepanol速 fk mechanically fastened with Gripfix system

Application techniques

Safety and functional efficiency, supporting construction

The mechanical fastening of Rhepanol fk with Gripfix system ensures secure, fast and effective laying.

Safety and functional efficiency

Clean, dry and even roof surfaces.

With mechanical fastening the roof sealing is separated from the lower layers and components across the complete area. Movements of these layers and components can therefore not pass on stresses to the sealing, which is significant for the prevention of damage, especially on lightweight roofs. The roofing membrane Rhepanol fk is rolled onto mechanically fastened Gripfix strips, providing optimal wind load distribution and securing the membrane permanently to the roof.

If Rhepanol fk is directly laid on concrete decks/screed allow the concrete/screed to set for at least 28 days. If Rhepanol fk is installed directly on concrete decks/screed, pre-coating of the main area with bitumen is required. Alternatively, a min. 0.2 mm thick PE foil can be installed as a separation layer. At flashings and cappings no pre-coating or PE foil is needed.

The membrane seams run perpendicular to the Gripfix strips and thus are not affected by wind uplift forces. The integrated highly tear-resistant synthetic fleece of Rhepanol fk allows diffusion of any retained moisture. Rhepanol fk is compatible with bitumen and can be applied without additional separation layers directly onto old bituminous sheets. The integrated synthetic fleece protects the membrane against movement originating from the substrate. Application instructions Supporting construction The supporting deck structure has to meet the requirements with regard to loadbearing capacity, deflection, anchorage and drainage. Substrates for application must be free of open cracks, concrete, rough and sharp projections. Joints have to be formed according to constructional requirements, as their width or movement may impede the functional efficiency of the roof seal.

The effect of air escaping from the building at the roof perimeter and at roof penetrations must be prevented. Therefore these areas have to be made airtight. In the case of profiled steel decking, seal around all openings and perimeters. For compatibility reasons, timber board cladding, chipboards and similar may be treated only with salt-based wood preservatives. Oil or solvent based impregnation agents must not be used. Real wood boarding must be thoroughly swept with a broom. In individual cases, a synthetic fleece 300 g/m2 may be useful as an additional protection layer in order to prevent perforation of the membrane by sticking out splinters. National standards and regulations must be observed.

Rhepanol® fk mechanically fastened with Gripfix system

Application techniques

Vapour control layer, thermal insulation layer

Vapour control layer

Thermal insulation layer

In the case of non-ventilated roofs, we recommend the following vapour control layers:

When designing the thermal insulation layer on steel profile supporting decks, attention must be given to load bearing capacity.

For non air-conditioned rooms (e.g. living rooms and offices or similar rooms without suspended ceiling): FDT vapour control layer fk (polyethylene) with µ x s = 120 m. In the case of aerated concrete supporting decks with correctly calculated thermal insulation, you may leave out a vapour control layer, if the room temperature stays below 20 °C and the relative air humidity inside the room will not exceed 65 %. In case of doubt, we recommend a calculation of the building physics in order to identify the diffusion characteristics of the roof build-up. With lightweight steel deckings, we also recommend in principle the installation of a separate vapour control layer, which should be formed as an air barrier according to the provisions of the Thermal Insulation Regulation. The FDT vapour control layer fk is applied with a seam overlap of 10 cm, with the seams being sealed with connection or seam tape. The vapour control layer must be taken up and flashed at connections and cappings; at roof penetrations it must be flashed. For rooms with high air condition loads: In case of air-conditioned rooms and rooms with high air condition loads, as well as high pressure rooms, there should be no mechanical fastening through the vapour barrier. In these cases please consult our experts to identify the right layer build-up and application method. National standards and regulations must be observed.

As materials for thermal insulation layers we recommend: For roof slopes up to 20°: large-sized insulation boards made of expanded polystyrene with rebated edge according to DIN EN 13163, size 1.20 x 1.20 m or 1.20 x 1.00 m. On top of the insulation boards, for fire protection reasons, the application of a fire protection layer – a specially coated woven glass cloth – will be necessary Flexible insulation boards or expanded polystyrene foam boards with backing according to DIN EN 13163. For fire protection reasons, bituminous sheets with an integrated glass fleece or fabric > 60 g/m2 may be necessary as a lining. Use linings with a PE foil or fleece facing. Large-sized non-flammable mineral fibre boards, according to EN 13162 with a point load of Fp > 650 N in accordance to EN 12430. Small-sized insulation boards can be used, provided they can be properly fastened. National standards and regulations must be observed. The guidelines of the insulation board manufacturer must be observed.

Thermal insulation layer, Rhepanol速 fk, mechanically fastened with Gripfix system

Insulation boards or board sections that are not sufficiently fixed with Gripfix must be secured in a stable position with additional fasteners (at least 2 fasteners/m2) prior to applying the roofing membrane. Insulation materials that are not dimensionally stable and which buckle or bulge must not be installed. Generally insulation boards must be laid brick-bond pattern.

System sketch Rhepanol fk Gripfix system with Rhepanol fk fire protection layer.

Rhepanol速 fk, mechanically fastened with Gripfix system The Gripfix strips are placed according to the wind uplift calculation and mechanically fastened. The Gripfix strip spacing is variable depending on the wind load requirements. The roofing membrane Rhepanol fk is then loose-laid with a seam overlap of 50 mm perpendicular to the Gripfix strips. The grip is achieved by thoroughly rolling the roofing membrane Rhepanol fk to the Gripfix strip. The membrane width is always 1.05 m. With the Gripfix system there is no need for various membrane widths. Depending on the substrate a variety of different fasteners may be used.

Application techniques

Fasteners/fastener spacing

Rhepanol fk can be mechanically fastened on roofs with any slope. For slopes exceeding 20°, application should be agreed with our experts. On profiled steel deckings and timber board cladding the Gripfix strips must be arranged perpendicularly to the corrugations or boards to achieve the most regular wind load distribution possible into the supporting deck.

On request, computer-based project specific calculations of the necessary amount of fasteners and Gripfix strip spacing are carried out, which may result in lesser amounts of fasteners than indicated in the table, provided the building has a favourable geometry. ■

If Rhepanol fk is directly laid on concrete decks/screed allow the concrete/screed to set for at least 28 days. Pre-coating of the main area with bitumen is then required in two consecutive coats. Alternatively, a min. 0.2 mm thick PE foil can be installed as a separation layer. At flashings and cappings no pre-coating or PE foil is needed.

Real wood boarding must be thoroughly swept with a broom. In individual cases, a synthetic fleece 300 g/m2 may be useful as an additional protection layer in order to prevent perforation of the membrane by sticking out splinters.

At all flashings and cappings, roof lights etc. the build-up must be specially secured by circumferential rows of fasteners or Gripfix strips (min. 4 fasteners/m). Note: ■

Max. spacing of Gripfix strips see table above.

Fastening spacing on the Gripfix strip min. 150 mm, max. 600 mm.

Fastener spacing on the same corrugation at profiled steel deckings must not be less than 200 mm.

Use only fasteners with washers of max. 50 mm width. The max. wind force (including safety factor 1.5) per m Gripfix strip is 1.5 kN.

The design load is max. 0.5 kN/fastener. Instructions of the fastener manufacturer must be observed. For building heights over 20 m and in special cases (e.g. airplane hangars, buildings near the coast, extreme exposure) each characteristic of the project location and special conditions must be taken into account.

Application techniques

Flashings and cappings

All flashings and cappings are carried out with Rhepanol fk flashing strips.

Additional requirements for roof refurbishment:

If the connecting membrane is bonded, then at flashing heights over 200 mm a full-size adhesive bond is necessary. Valley areas are left unbonded at a width of 200 mm to allow movement compensation. If the connecting membrane is mechanically fastened with Gripfix strips the following spacing must be observed (see sketch): – Distance of the first Gripfix strip from the internal corner of the parapet max. 100 mm – Spacing between the Gripfix strips or distance between Gripfix strip and upper capping max. 500 mm.

In the case of uneven substrates, protection layers are necessary. Rigid polystyrene foam insulation boards or purlite sheets can be used.

The strength of the supporting deck is crucial for the anchoring of the fastening elements. If there is doubt about the strength, e.g. of woodwool slabs or aerated concrete panels, pullout tests will be necessary to define the amount of fasteners depending on the project.

The necessary flashing and capping profiles are cut from laminated metal sheets and bent according to the specification and the local requirements like galvanized sheets. Forming of flashings and cappings is identical for all application methods. You will find details on this topic in the drawings ´Roof Design`.

Gripfix strip max. 500 mm

With wall flashings, the upper edge of the Rhepanol fk roofing membrane is pressed to the substrate with rigid wall connection profiles such as ´Classic` and additionally secured with FDT sealant A or S. The two-part FDT roof edge trims ensure flexible, yet windproof capping of the roof perimeter. When laying roofing membranes Rhepanol fk, in the area of cappings, bracket-mounted gutters and flashings also Rhepanol laminated metal sheets can be used.

Application techniques

Safety and functional efficiency, supporting construction, vapour control layer

Safety and functional efficiency

Joints have to be formed according to constructional requirements, as their width or movement may impede the functional efficiency of the roof sealing.

The roof slope should not exceed 3° to prevent the ballast slipping off.

Rhepanol fk is compatible with bitumen and can be applied without additional separation layers directly on old bituminous sheets.

An intrusion of air underneath the roof covering at the roof perimeter and at roof penetrations must be prevented. Therefore these areas have to be made windtight.

The integrated, highly tear-resistant synthetic fleece of Rhepanol fk allows diffusion, ensuring reliable vapour pressure compensation. Furthermore the fleece backing provides protection against stresses originating from the substrate.

For compatibility reasons, timber board cladding, chipboards and similar may be treated only with salt-based wood preservatives. Oil or solvent based impregnation agents must not be used.

National standards and regulations must be observed.

Because of loose laying, the roof covering is separated from the other layers of the build-up across the complete area. Movements and cracks in the supporting construction are not transferred into the roof covering. The ballast ensures the membrane remains secure against wind uplift forces.

Application instructions Vapour control layer Supporting construction ■

The supporting deck structure has to meet the requirements with regard to load-bearing capacity, deflection, anchorage and drainage.

Clean, dry and even roof surfaces.

If Rhepanol fk is directly laid on concrete decks/screed allow the concrete/screed to set for at least 28 days. Pre-coating of the main area with bitumen is then required in two consecutive coats. Alternatively, a min. 0.2 mm thick PE foil can be installed as a separation layer. At flashings and cappings no pre-coating or PE foil is needed.

Substrates for application must be free of open cracks, rough concrete, sharp edges and stones.

In the case of non-ventilated roofs, we recommend the following vapour control layers: ■

For non air-conditioned rooms (e.g. living rooms and offices or similar rooms without suspended ceiling): FDT vapour control layer fk (polyethylene) with µ x s = 120 m.

In the case of aerated concrete supporting decks with correctly calculated thermal insulation, you may leave out a vapour control layer, if the room temperature stays below 20 °C und the relative air humidity inside the room will not exceed 65 %. The vapour control layer is applied with a seam overlap of 100 mm, with the seams being sealed with connection or seam tape. The FDT vapour control layer fk must be taken up and flashed at connections and cappings; at roof penetrations it must be flashed.

Application techniques

Thermal insulation layer, Rhepanol® fk, loose-laid, ballast

For rooms with high air condition loads (e.g. swimming pools, air-conditioned rooms): – aluminium reinforced bitumen, – vapour control membrane with metal tape reinforcement.

At all flashings and cappings, built-in details etc. you will need linear perimeter fixing with at least 4 fastening elements/m.

National standards and regulations must be observed.

Immediately apply ballast on loose-laid roofing membranes to secure its position against wind uplift.

Ballast

Thermal insulation layer Suitable materials are: You must bear in mind tread-fastness when designing the thermal insulation layer on steel profile supporting decks. Expanded polystyrene foam boards with rebated edge according to DIN EN 13163 and a length of max. 1.25 m are especially suitable materials for thermal insulation layers. With roof areas for walking on, insulation materials with higher compression strength must be used in accordance with the expected loads. Insulation materials that are not dimensionally stable and which buckle or bulge must not be installed. The insulation elements must be laid in a brick-bond pattern.

bulk gravel layers, min. 50 mm thick, washed natural uncrushed stones, fraction 16/32 or 20/40.

■ paving

slabs in a fine gravel bed on a protection layer.

If appropriate gravel is not available or the gravel is applied pneumatically, then, as under paving slabs, you will need an additional protection layer (e.g. synthetic fleece or FDT protection layer). Under screed you will have to apply the FDT protection layer (the overlaps have to be welded). PE layers and coarse rubber protective sheets must have an underlying synthetic fleece layer. Examples for ballast

National standards and regulations must be observed. The guidelines of the insulation board manufacturer must be observed.

Rhepanol fk, loose-laid Roofing membranes Rhepanol fk are loose-laid with a seam overlap of 50 mm. The membrane seams are quickly sealed with the prefabricated self-sealing edge almost independent from weather conditions.

For ballast, the provisions of national wind load standards must be observed. At building heights over 20 m and for roofs with high wind exposure (e.g. tower-style, detached buildings, airplane hangars and buildings near the coast) it is necessary to define appropriate project-related measures for membrane position stability.

Rhepanol® fk loose-laid with ballast

Application techniques

Flashings and cappings, roof refurbishment

Flashings and cappings All flashings and cappings are carried out with Rhepanol fk flashing strips. With flashing heights of over 200 mm, full-size adhesive bonding of the covering at the upstand is necessary. Valley areas are left unbonded at a width of 200 mm to allow movement compensation. The upper edge of the Rhepanol fk roofing membrane is pressed to the substrate with rigid wall connection profiles such as ´Classic` and additionally secured with FDT sealant A or S. The two-part FDT roof edge trims ensure flexible, yet windproof capping of the roof perimeter. When laying roofing membranes Rhepanol fk, in the area of cappings, bracket-mounted gutters and flashings also Rhepanol laminated metal sheets can be used. The necessary flashing and capping profiles are cut from laminated metal sheets and bent according to the specification and the local requirements like galvanized sheets. The forming of flashings and cappings is identical for all application methods. You will find details on this topic in the drawings ´Roof Design`.

Additional requirements for roof refurbishment: ■

Thoroughly sweep the roof area. Remove any blisters, projections and coarse roughness.

On rough substrates (such as embedded gravel), a protection layer is necessary. We recommend suitable polystyrene insulation boards, which provide additional insulation at the same time.

Temporary storage of gravel must not exceed the maximum load of the supporting deck.

Soiled gravel must be cleaned (e.g. by sieving). Otherwise, appropriate protection layers such as synthetic fleece 300 g/m2 must be applied.

Rhepanol® fk bonded fixing

Application techniques

Safety and functional efficiency, supporting structure, vapour control layer

Safety and functional efficiency

■ The

necessity for pre-coating to provide reliable adhesion and dust bonding depends on the substrate conditions.

Bonding Rhepanol fk in stripes ensures maximum possible mobility of the roofing membrane. The integrated, highly tear-resistant synthetic fleece of Rhepanol fk allows diffusion, thus ensuring reliable vapour pressure compensation and secure bonding to the substrate. Rhepanol fk is compatible with bitumen and can be bonded without additional separation layers, directly to old bituminous sheets. The integrated synthetic fleece protects the membrane against stresses originating from the substrate.

– It is not necessary to pre-coat coated profiled steel deckings, except when welding on bituminous sheets (only as bonding agent).

National standards and regulations must be observed.

Application instructions

Vapour control layer

Supporting construction

In the case of non-ventilated roofs, we recommend the following vapour control layers:

The supporting deck structure has to meet the technical requirements, especially for loadbearing capacity, deflection, anchorage and drainage.

Substrates for application must be free of open cracks, rough concrete and sharp projections.

Joints have to be formed according to constructional requirements, as their width or movement may impede the functional efficiency of the roof waterproofing.

An intrusion of air underneath the roof covering at the roof perimeter and at roof penetrations must be prevented. Therefore these areas have to be made windtight.

Clean, dry and even roof surfaces.

If Rhepanol fk is directly laid on concrete decks/screed allow the concrete/screed to set for at least 28 days. Pre-coating of the main area with bitumen is then required in two consecutive coats.

– Aerated concrete panels must always be pre-coated.

For non air-conditioned rooms (e.g. living rooms and offices or similar rooms without suspended ceiling): vapour control membrane with µ x s over 100 m. In the case of aerated concrete supporting decks with correctly calculated thermal insulation, you may leave out a vapour control layer, if the room temperature stays below 20 °C und the relative air humidity inside the room will not exceed 65 %.

For rooms with high air condition loads (e.g. swimming pools, air-conditioned rooms): vapour control layer with aluminium reinforcement, glass fleece or woven glass tissue reinforcement.

In case of doubt, we recommend a calculation of the building physics in order to identify the diffusion characteristics of the roof build-up.


Rhepanol® fk bonded fixing

Application techniques

Vapour control layer, thermal insulation layer

With lightweight steel deckings, we also recommend in principle the installation of a separate vapour control layer, which should be formed as an air barrier according to the provisions of the Thermal Insulation Regulation. ■ The

vapour control layer must be taken up and flashed at connections and cappings, at roof penetrations it must be flashed.

standards and regulations must be observed.

Large-sized non-flammable mineral fibre boards, according to EN 13162 with a point load of Fp > 650 N in accordance to EN 12430. With bonded application using mineral wool insulation material, the type of insulation material and the adhesive/amount of adhesive needed is to be defined depending on the project.

■ National

As a lining, use bituminous sheets without PE backing.

Note:

Generally insulation boards must be laid brickbond pattern. Insulation materials that are not dimensionally stable and which buckle or bulge, or insulation elements with insufficient lining stability must not be installed.

For bonding the insulation layer with FDT adhesive U, use vapour control membranes without PE backing or talcum coating. Thermal insulation layer The thermal insulation layer is to be designed in accordance with the thermal protection requirements. As materials for thermal insulation layers we recommend: ■

Flexible insulation boards or expanded polystyrene foam boards according to EN 13163 with backing. For fire protection reasons, bituminous sheets with an integrated glass fleece or fabric > 60 g/m2 may be necessary as a lining.

Bonding of the thermal insulation layer is preferably done with FDT adhesive U, a onecomponent polyurethane adhesive. For roof slopes exceeding 7°, additional supporting measures are necessary to prevent the materials slipping off while the adhesive is curing. For further information on the adhesive and its application see data sheet FDT adhesive U. ■ National

Adhesive consumption depends on the location and height of the building and on the bonding substrate. For building heights over 20 m and in the case of roofs with high wind exposure (e.g. towerstyle, detached buildings, airplane hangars and buildings near the coast), it is necessary to calulate the amount of adhesive needed to fix the membrane securely. For roof slopes exceeding 15°, additional mechanical fastening may be necessary to prevent the roofing membrane slipping off while the adhesive is curing. At slopes exceeding 20°, application should be agreed with our experts. For information on the adhesive, its application and processing see data sheet Rhepanol adhesive 90 (page 71).


Rhepanol® fk bonded fixing

Application techniques

Linear perimeter fixing, flashings and cappings, roof refurbishment

Linear perimeter fixing A linear perimeter fixing at flashings and cappings is necessary: ■

With supporting decks made of galvanized profiled steel.

In general, with bonded roof build-ups with mineral fibre insulation materials, independent from the supporting deck.

The perimeter fixing of the roof build-up, including the roofing membrane, is achieved in each instance with at least four fixings per metre.

Flashings and cappings All flashings and cappings are carried out with Rhepanol fk flashing strips. With flashing heights of over 200 mm should be fully

adhered to the upstand. Valley areas should be left un-bonded for an area of 200 mm to allow for movement. The upper edge of the Rhepanol fk roofing membrane is pressed to the substrate with rigid wall connection profiles such as ´Classic` and additionally secured with FDT sealant A or S. The two-part FDT roof edge trims ensure flexible, yet windproof capping of the roof perimeter. When laying Rhepanol fk to parapets, bracket mounted gutters and flashings it may be appropriate to use Rhepanol laminated metal flashings. The necessary flashing and capping profiles are cut from Rhepanol laminated metal sheets and bent according to the specification and the local requirements like galvanized sheets. Forming of flashings and cappings is identical for all application methods. For drawing example see ´Roof Design`.

Additional requirements for roof refurbishment: ■

Before overlaying with Rhepanol fk the adhesion between the old roofing layers, as well as to the supporting deck must be completely secure. Otherwise mechanical fastening will be necessary.

■ With

old roofs bonded with cold bituminous adhesive a mechanical fastening of the old roof is obligatory due to the plastic dimensional dynamics of the cold bituminous adhesive.

The substrate must be suitable for bonding, free from chippings and thoroughly cleaned.

Product view Rhepanol laminated metal sheet.

Application

Processing

When using Rhepanol fk, in the area of cappings, bracket-mounted gutters and flashings also Rhepanol laminated metal sheets can also be used. The necessary flashing and capping profiles are cut from laminated metal sheets and formed according to the specification and bent to the required dimensions like galvanized sheets.

■ Rhepanol

Range of application Steel drip angle at bracket-mounted gutters Wall capping ■ Wall connection profile ■ Roof edge trim ■

laminated metal sheets should be cut with a sharp tool and with the varnish side up. Thus, trimming of the cut sheets will not be necessary. ■ The clearance should be 0.03 – 0.04 mm. Rhepanol laminated metal sheets can be processed on any standard bending machine. ■ A bending radius of 1.2 – 1.8 mm is to be observed. ■ Processing (cutting, bending) of the Rhepanol laminated metal sheets should be done at room temperature, approx. 18 °C.

Properties Rhepanol laminated metal sheets with an overall thickness of 1.4 mm consist of hot galvanized metal sheets with a Rhepanol h facing and a varnish backing.

Substrates Suitable bearing substrates for fastening are concrete, full brickwork, timber, derived timber products, steel etc. Fasteners must be adapted to the substrate according to the following table and with respect to the corresponding manufacturer‘s instructions.

Rhepanol® laminated metal sheet

Suitable fasteners for substrates consisting of lightweight or aerated concrete, or vertically perforated bricks are to be agreed with the manufacturers. In order to prevent premature corrosion, a FDT synthetic fleece layer 300 g/m2 should be installed between the sheets and the substrate (e.g. concrete or aerated concrete). Bearing substrates Concrete or full brickwork

Suitable fastening elements Nylon plugs and corrosionproof impact plugs or screws, hammer impact rivets

The integrated self-sealing edge of Rhepanol fk allows for seam connection with the Rhepanol laminated metal sheet without open flame, hot air or solvent welding or additional adhesives!

When combining Rhepanol laminated metal sheets and Rhepanol fk, at all flashings and cappings make sure that seam connections are not in the vertical area and that the seams do not have to take any peeling or shearing forces. Rhepanol laminated metal sheets must not be used as linear fastenings for bearing horizontal forces!

Form of supply Timber and Chipboard screws derived timber products Steel

Rivets, bolts or self-tapping screws

Application instructions Rhepanol laminated metal sheets (de-burred cut edges) are butted against each other with a clearance of 4 mm (profile length max. 2.00 m), in order to permit temperatureinduced elongation of the profiles. ■

A 38 mm wide FDT adhesive tape is affixed to the joint area.

Afterwards, a 150 mm wide Rhepanol h strip is applied which is homogeneously welded with hot air.

In order to avoid capillary action at profile joints, prior to applying the Rhepanol fk trim strips, the membrane edges of the 150 mm wide Rhepanol h strips must be sealed with Rhepanol paste.

Rhepanol® adhesive 90

Sloping areas

At roof slopes over 15°: if necessary, apply additional mechanical fastening to prevent the roofing membrane slipping off while the adhesive is curing. ■ At roof slopes over 20°: application must be agreed with our technical department. ■

Storage Not frost-proof. Best storage in a dry place at + 10 °C.

Curing ■

If bituminous layers are used as a sealing sublayer curing time may be extended. However, even in very unfavourable conditions, the adhesive will be completely hardened within several days.

Under normal conditions a sufficient initial hardness is reached within 4 to 8 hours. The curing time of the adhesive depends on the evaporation of the solvents. Longer evaporation time reduces curing time.

Maximum period of storage: 24 months in tightly closed original containers. For further application instructions, see container and installation instructions Rhepanol fk.

FDT adhesive U

Application

1)

For consistent bonding of thermal insulation materials and bituminous vapour control sheets. ■ To be applied in stripes with the FDT universal application trolley, equipped with a special adapter. ■

Application method With the FDT universal application trolley and adapter for FDT adhesive U (6.5 kg containers) for even substrates. ■ Manual application should be limited to roof areas that cannot be worked on with the application trolley, such as small areas between roof lights. ■

Properties Sloping areas Liquid, one-component solvent and CFC free polyurethane adhesive ■ High adhesiveness ■ Elastic, no embrittling ■ Consistent at temperatures from – 40 to + 100 °C ■ High thermal stability ■ Solvent and CFC free, does not affect rigid polystyrene foam ■ Foams and compensates small level differences of the substrate ■ Simple application method which needs no power supply ■ No risk of burning or fire ■

Substrate The bonding areas have to be solid, even, clean, dry and free of grease and oil. Adhesive consumption For building heights up to 20 m the consumption and the amount of adhesive stripes required are indicated on page 45 in the table “FDT adhesive U consumption for thermal insulation”. For detailed application instructions see the installation instructions Rhepanol fk and the containers.

At roof slopes over 7°: ■ Preferably, the adhesive should be applied in direction of the slope. ■ Supporting measures should be applied to prevent the materials slipping off while the adhesive is curing. Fascia boards, for example, can be used as abutment. At roof slopes over 20°, application must be agreed with our experts. Curing The curing time of the adhesive depends on the temperature as well as on the ambient humidity and the air humidity. Normally a sufficient initial hardness is reached within 1 to 3 hours. A slight moistening reduces the curing time. ■ In case of bonding vapour-proof materials, the curing time may be extended. However, even in very unfavourable conditions, the adhesive will be completely hardened within several days. ■ With high summer temperatures (approx. 25 °C and above) and low air humidity, it is recommended slightly moistening the substrate after applying the adhesive to ensure a sufficient degree of moisture for foaming. ■ Warning: Must not be used to bond Rhepanol roofing membrane. ■

1) Due to its foaming characteristics FDT adhesive U is not approved for bonding of bitumen sheet compensation layers, onto which the roofing membranes are directly bonded.
