All Bereco windows and door sets should be fitted into preformed openings, which are at least 10mm larger (5mm all round) than the overall frame size. Using a spirit level, ensure windows and door sets are installed plumb and square prior to fixing. Bereco recommend our windows and door sets be installed using metal fixing straps/plates.
