WHY DOUBLE GLAZING

Warmer, quieter, cheaper to run.

Double glazing works by trapping an insulating layer of gas between two panes of glass, with a low-emissivity coating that reflects warmth back into the room. The result is a home that holds its heat, shrugs off outside noise and costs less to keep warm – which is why A-rated double glazing comes as standard on every window we fit.

Warmer home, lower bills

The insulating cavity keeps heat in, so your rooms stay warmer and your heating works less.

Quieter rooms

Two panes and a sealed cavity help shut out traffic and street noise.

Less condensation

A warmer inner pane and warm-edge spacers cut down on misting and damp around the glass.

More secure

Tougher than single glazing, with toughened and laminated glass options for extra protection.

A-rated as standard

Every window we fit comes with energy-efficient, A-rated double glazing as standard.

Made to measure

Fitted in any window style and finish, in uPVC or aluminium.

THE DETAIL THAT MATTERS

Built to keep the heat where it belongs.

A-Rated Sealed Units

Two panes with an insulating gas-filled cavity and a low-E coating that reflects heat back into the room.

Warm-Edge Spacers

The spacer around the glass edge reduces heat loss and condensation where windows lose warmth most.

Glass Upgrades

Add obscured, toughened, laminated or acoustic glass for privacy, safety or extra noise reduction.
