All sills from Passive sills are manufactured from high density expanded polystyrene and coated with our Passive Sills polymer resin. This coating has been laboratory tested. The product certifications are outlined below along with a description of the tests carried out to obtain these certifications. A Passive Sill can be used as an over sill, which covers an existing window sill (see the Installation Guide for more details) or for new window sill installations for example in a new build.
