The Swistherm System A lightweight, thin-coat insulated render system primarily suited to new build applications, designed to satisfy differing substrate conditions and building height requirements. Insulation slabs are adhesive and mechanically fixed direct to a continuous substrate and faced with a durable, decorative top-coat - Silicone render is used for enhanced overall performance, with Mineral renders available as the eco-friendly option. Both finishes can be applied with rolled or dragged surface texture, in a wide range of colours. Applications • For new build applications, where the structure provides continuous support for the insulation slabs • Suitable for remodeling and specialist façade treatment details • For unrestricted use on buildings up to 6 storeys and high rise applications, subject to Alumasc’s high rise policy

Performance • BBA approved, fully warranted system with

life expectancy in excess of 30 years

• Manufactured to ISO9001:2000 and ISO14001:2004 Quality and Environmental Management standards • Fully weather resistant, whilst remaining vapour permeable

• Eliminates cold bridging, condensation and mould growth • 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 • Fire tested to comply with BRE 135 93/2914
