Stylite External Wall Insulation (EWI)

by Styrene Packaging & Insulation

Stylite White and Grey Expanded Polystyrene EWI boards are manufactured in 1200x600 sheets to assist with handling, and are available in either PlusTherm or EPS70 with a Fire Retardant Additive. Suitable for newbuild or refurb applications and can be mechanically or adhesively fixed in position. Render adheres well to EPS allowing easy finishing of the EWI system.


Stylite external wall insulation is a quick and effective way to dramatically increase the thermal performance of any building and can be applied with almost any render or cladding system to produce a full EWI system. EWI board systems are often used to upgrade existing buildings with retroft solutions but are also used for new-builds. The long lifespan and water resistant properties make Stylite expanded polystyrene the perfect insulation for EWI applications.
