Slimline double glazing allows homeowners to gain thermal and sound benefits without compromising the character, charm or value of original timber windows.
Slimline units use narrower cavities than standard double glazing and can closely replicate the appearance of single glazing. Depending on specification, high-performance units can achieve low U-values while retaining narrow glazing bars and traditional putty-line detailing.
Units can be installed to new and restored traditional windows and doors where the existing joinery is suitable.
