SPI Stylite EPS Railboard external wall insulation (EWI) boards can be used in conjunction with any render system supplied by providers across the UK. It provides an economical way of adding better thermal performance to properties without insulation in their cavities. Our mechanical EWI boards are available in Stylite Plustherm, for a better thermal performance at a reduced thickness & Stylite EPS 70E, standard white polystyrene. Both grades are of 'E' quality, and contain a fire retardant additive.

The boards are available in a range of different sizes and edge details and are lightweight, easy to cut and handle and provide an excellent surface for all renders. Mechanically fixed EWI boards must be installed as per the EWI providers instructions. For details of EWI installers of our products, thermal performance or any other information, please contact our Sales Team on 01274 691777
