Swistherm EWI
A BBA approved, fully warranted system with an effective life in excess of 30 years Swistherm is fully weather resistant whilst remaining vapour permeable and allows the fabric of the building to act as a heat store, increasing thermal efficiency The system eliminates cold bridging, condensation and mould growth and protects the structural fabric, limiting movement and thermal shock and freeze-thaw cycles associated with traditional brickwork façades The Swistherm EWI system is highly resistant to impact damage, is rated Class 0 for surface spread of flame and contributes to sound reduction within the external wall construction Applications Construction Types - primarily suited to new-build construction types where the structure provides continuous support for the insulation slabs Buildings up to 6 Storeys - suited for unrestricted use; High Rise - suitable subject to Alumasc's high rise policy Insulation Insulation slabs are mechanically fixed direct to a continuous substrate. A choice of insulation thicknesses and materials are available, achieving very low U-values Swistherm insulation options include Mineral Wool, Expanded Polystyrene, Grey EPS and Cork.
