Swisslab EWI - Refurbishment


Swisslab - The leading EWI system for overcladding existing properties


  • The Swisslab EWI system is BBA approved, with an effective life in excess of 30 years. It is fully warranted when applied in accordance with the Alumasc project specification and installed by an Alumasc registered contractor
  • The system allows the fabric of the building to act as a heat store, increasing thermal efficiency.
  • Swisslab is fully weather resistant whilst remaining vapour permeable. It also eliminates cold bridging, condensation and mould growth
  • It is highly resistant to impact damage and is rated Class 0 for surface spread of flame. It also contributes to sound reduction within the external wall construction


  • Swisslab is mainly suited to building refurbishment, particularly social housing, thus contributing to urban regeneration and can be installed over solid masonry, concrete panels (NLB), No Fines concrete and masonry with cavity and is particularly suited to the treatment of non-traditional house types such as BISF, Orlit, Wates, Cruden, Airey and Athol 
  • It is unrestricted for use on buildings up to 6 storeys and high rise applications that comply with Alumasc’s High Rise Policy


  • Insulation, which is mechanically fixed direct to a continuous substrate, includes Phenolic, PIR, Mineral Wool, Expanded Polystyrene, Grey EPS and Cork
  • The choice of thicknesses and types of insulation available ensure very low U-values are achieved.
