Tested by Napier University, one of the leading building engineering research centers in the UK, Capvond Composites's Cast Composite Sills can be fitted together with a polyurethane foam backing to further reduce "Cold Bridging". The combination of the Capvond Composites Cast Sill's porosity of less than 0.2%, and the ability to bond efficiently substrates such as polyurethane foam to any part of the sill, provides a combination which reduces heat transfer between the exterior and interior at sill level.
Manufactured in lengths of up to 2.4m and a wide variety of depths, widths and heights to customer's specifications, Capvond Cast Composite Sills do not require mechanical handling when fitting or lifting, and eliminates unsightly joints which lead to staining on the brickwork or render below.
Using Cast Composite building products will reduce the carbon footprint which is created by mechanical handling of precast concrete and stone products. 37% of the weight of precast concrete in volume, less than 0.2% porosity. Lower porosity than precast concrete and precast stone.
