The insulation is fixed to the walls using special permanent plastic insulation fixings (PRS use the Insofast range)
The two or three thin coats of render is then applied. The finish is available in a wide range of colours and can even be made to look like brick work.
The property to the side is the old party wall where a subsiding property was demolished, the original render was allowing water penetration and excessive heat loss. The new insulated render system solved all the issues and the tenants are delighted with the final result.
The system PRS installed in this project is supplied by Wetherby Building Systems Ltd.
