20mm White Polystyrene Board (EPS) for External Wall Insulation (pack of 30)

20mm White Polystyrene Board 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.

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.
