The Images Swisspan System Small – choose from

An insulated render system used to overclad existing properties where mechanical fixing is problematic and restricted to structural elements – typically structural frames with non load-bearing steel or concrete infill panels and non-traditional house types such as Airey Duo Slab, BISF, Cornish, Crudens and Unity. Insulation materials are mechanically fixed to a galvanised steel horizontal support rail system that spans between structural columns, and are then faced with M.R. Polymer modified traditional renders or lightweight Silicone or Mineral renders. Applications • For refurbishment applications, where the structure

does not provide continuous support for insulation

• Suitable for new build where specific project

detailing requires

• Ideal for problematic substrates or uneven

remodelling applications

• For unrestricted use on buildings up to 4 Storeys

Performance • BBA approved, fully warranted system with life

expectancy in excess of 30 years

• Manufactured to ISO9001:2000 and ISO14001:2004

• Fully weather resistant, whilst remaining

vapour permeable

• Integrated rail system provides secure fixing and

load transfer to underlying load bearing structure

• Allows the fabric of the building to act as a heat

store, increasing thermal efficiency

• Eliminates cold bridging, condensation and mould growth • Reduces heating costs and carbon dioxide emissions • Protects the structural fabric, limiting movement

and thermal shock and freeze-thaw cycles associated with traditional brickwork façades

• Highly resistant to impact damage • Rated Class 0 for surface spread of flame

Technical expertise and tailored project support •

Design & Specification Support Site surveys, detailed design meetings, project specific elevational colour schemes, CAD drawings and product samples, tenant involvement programmes

Calculations Thermal calculations, condensation risk analysis, wind loading calculations (for high rise projects)

Specification Support Detailed specification (to NBS format), health and safety sheets and product data sheets

Installation, Aftercare & Warranties Application by Alumasc approved contractors, Alumasc on site support, routine maintenance requirements, full package of warranty options
