Windows

We make a wide range of windows - from double-glazed conservation sashes, which will fit within your existing box-frames. To bespoke casement windows, which replace ugly mid-century storm-proof casements with more elegant and thermally efficient casement windows.

All our windows are supplied fully draft-proofed and use state of the art ‘slim line’ double- glazed units.

Thermal efficiency

We use special slim double-glazed units, which can be puttied-in to the windows. This avoids the need for unnecessary beading, which is commonly the first thing to rot on double-glazed timber windows. It also allows us to retain a sympathetic faithfulness and elegance to windows we are replacing. These double glazed units come in 12mm and 14mm thickness and are configured as follows:

• 12mm units - (4mm low E glass / 4mm cavity filled with krypton gas / 4mm glass) achieving a centre pain u-value of 1.9
• 14mm units - (4mm low E glass / 4mm cavity filled with krypton gas / 4mm glass) achieving a centre pain u-value of 1.5
