The exclusive deep GRP cill is available as standard on the Symphony sash window and the Vintage sash window and is a beautiful feature designed to achieve the authentic appearance of an original 3” timber, useful for use in a Conservation Area.
The deep 56 mm cill is indistinguishable from the other PVC-U sections because all are bond wrapped in the same Renolit foil to maintain the appearance of timber.
The deep cill is 16.8 times stronger that a regular cill and this strength allows larger and more unusual windows to be replicated more authentically, for instance where required in sea front hotels, renovated / converted former schools, industrial buildings and ecclesiastical buildings.
