INSULATION QUICK GUIDE

Quality Electric Underfloor Heating

At only 10.5mm this board presents a minimal height increase and is ideally suited for refurbishments Our insulation board is manufactured without the use of CFC or HCFC blowing agents

!

Our insulation board on its own will not satisfy current insulation requirements but when used will significantly improve underfloor heating efficiency.

!

We recommend the use of a flexible cement based tile adhesive to adhere our insulation board to the substrate. Your supplier will be able to advise and supply this. (For application of adhesive follow the adhesive manufacturers recommendations).

It is also environmentally friendly with zero Ozone Depletion Potential (ODP), is fully recyclable and reduces your energy costs.

!

Do not use over the top of underfloor heating.

Cut to size using a wood saw or craft knife, making installation very quick and easy.

Concrete substrate

Timber substrate

(Use Coated Boards)

(Use Uncoated Boards)

Use plastic washers and suitable screws to fix the boards in place (take care to identify pipe work and electrical cabling before fixing the screws into the floor).

Apply a layer of flexible adhesive to secure the insulation boards to the substrate.

! Each system should be tested with a multi-

meter before it is unpacked to ensure it is in full working order. Complete the enclosed test results form as your customer will need it in order to complete the warranty application form on our website.

Apply primer if specified by the tile adhesive manufacturer’s guidelines.

INSTALLATION GUIDE

Quality Electric Underfloor Heating

Measure the available floor space excluding any fitted cupboards, sanitary ware, mat wells etc, and allow a 100mm border around the edge of the room Apply primer if specified by the tile adhesive manufacturer’s guidelines See page 6 for details on floor preparation, Thermostat and floor sensor installation.

Refer to specific Thermostat installation instructions.

Work out the cable spacing using the calculation below: Available floor space (m2) x 100 Cable kit length (m)

= Spacing (cm) Optimum spacing for 150w/m2 is 7cm Minimum spacing: 50mm
