In addition, to compliment this lock, our side-hung casement windows can be fitted with hinge guards as an optional extra.

Energy Ratings

The BFRC (British Fenestration Rating Council) is an independent body which is leading the development and application of window energy ratings. The Window Energy Rating label is similar to the EU label used on fridges, washing machines and light bulbs. It calculates precisely the overall u-value of the entire window, taking into account solar gain and heat loss through air infiltration as well as climate data. You can log on to the BFRC website at to verify any companies claims to be A-rated certified.
