Where they're used

On top of existing PVC window sills in sheltered locations.

Oversill flashings are adhesively fixed directly to the PVC sill below, making installation quick and clean. Because it relies on adhesive fixings, it is not recommended for exposed locations where wind-driven rain could work behind the profile
