About This Profile Family
Our window heads are a lightweight alternative designed to replicate traditional stone window heads. Window head profiles are supplied to suit different wall build-ups and are engineered to your window opening width. Standard lengths run from 660mm to 2352mm overall, for window openings from 460mm to 2152mm; wider openings are made to order. Each window head can be combined with a keystone (specify at time of ordering).

Installation Guidance
- ·On facing brickwork, the adjoining brick/block build-up must be coordinated to suit the profile (by others).
- ·Adjoining wall finish as per project specification (by others).
- ·Profiles are normally fixed with a 3-strip adhesive bed and Insta-Stik secondary fixing. Mechanical fixing is rarely needed; where the size or complexity of a profile calls for it, this is reviewed at design stage.
