Keep your original look, but enjoy optimum thermal performance.

Glass and Window Solutions specialise in the replacement of double glazed units into timber single glazed windows. This involves us routeing out the existing rebate, we then insert and seal the new double glazed units back into the existing timber joinery. This keeps the original, classic appearance of the window, but enhances the already efficient thermal performance that timber offers.
