St Johns Window Centre are proud to show our BFRC labels for our  Rated Energy Efficient Windows.

PVCu Window is fully reinforced with steel for maximum strength (unfortunately this does effect thermal performance) and double glazed with Pilkington EnergiKare glass units.

Windows can be made in white or woodgrain PVCu and is the same product we  have  manufactured for many years with the addition of argon gas and low iron glass as standard, where they used to be an extra option.

Aluminium Window is double glazed with Planitherm Total + Glass units as standard

Due to the strength of these products they can be used in all installations
