In these current economic times when energy prices are soaring, it makes even more sense to consider installing the highest performing energy rated double glazing on the market. Here at South Lakes Windows Ltd we not only achieve an A+8 rating on all our UPVC casement windows as standard, but obtain an A Rating on all our timber casement windows, as well as all Sliding Sash windows. In order to achieve such ratings most companies have to sacrifice the re-inforcing within the frame, however at South Lakes Windows Ltd we have managed to achieve all the ratings, whilst still incorporating the necessary re-inforcing with the frames and therefore not jeopardising strength and security.
