20mm White Expanded Polystyrene (EPS) for Insulated Render Systems - Ceresit CT305 (pack of 30)

20mm White Expanded Polystyrene (EPS) for Insulated Render Systems - Ceresit CT305 is a very lightweight and easy to handle and install, expanded polystyrene (EPS) board specially designed to be used as a part of various external wall insulation systems. It can be used in applications requiring transfer of small mechanical loads. Ceresit CT 305 White EPS Polystyrene board is an excellent insulation material for joint-less insulation systems for external walls (EWI) of buildings. This board's high resistance to tearing and shearing allows for safe insulation for all types of thin-layer renders, such as mineral renders, acrylic renders and silicate renders.

Please note polystyrene boards that we sell may not be purely white as per picture. Some of our depots may keep polystyrene with black dots (with improved performance). If you need purely white polystyrene sheets for your projects please contact us before placing an order.
