Fitting Guidance

Each board is 2m in length. Choose your desired depth from the options. One pair of end caps is supplied per board. Please note all boards cover approximately 10mm less than the displayed depth due to the 10mm thick lip on the front. For example, a 200mm board covers 190mm from front to back.

Basic fitting steps include cutting the capping to length, cutting the back edge to match the window board depth plus 9mm, applying adhesive to the window board, and placing the capping firmly on top. End caps can be trimmed and fixed with superglue. A decorators caulk can be applied around the edges for a neat finish.
