Finishing
Prior to installation, it is essential to coat all faces and edges of both the frames and the doors with a good quality sealer to protect from moisture ingress. At least 3 topcoats will be necessary on top of the sealer coat to adequately seal and protect the wood. Failure to undertake this may result in shrinkage, warping, twisting and splitting of the frame and the doors. Water based stains, paints or varnishes are not recommended.

Installation
Brick Wall [ W4, W6 & W8 ] The brick wall should be lined with polythene in between the brickwork and the frame. Stud Wall [ W4, W6 & W8 ] The opening of the plasterboard faced stud wall needs to be lined with wood onto which the frame can be fixed. If the wall is thinner than the frame width (133mm) the frame width can be reduced.

NB. Component dimensions and frame sizes should be checked/verified on-site prior to creating the requisite opening. LPD cannot be held liable for the ramifications resulting from failure to accurately confirm component dimensions and frame sizes, which might vary slightly in the event of the need to change suppliers.
