Double Glazing in Northampton

How double glazing keeps your home comfortable

Single glass lets heat straight through. Double glazing puts two panes in one sealed unit, held apart by a spacer bar, with air or an inert gas such as argon trapped in between. That layer acts as a barrier, so heat moves through the window far more slowly.

You notice it in a few ways. Rooms warm up faster and hold their heat after the heating goes off. The cold zone you feel when you sit near a window shrinks. In summer, the same barrier helps stop rooms overheating.

Our uPVC windows can reach window energy ratings as high as A. To see your home's overall EPC rating and where it loses heat, use our free energy check.

Condensation, draughts and noise

Condensation forms when warm, moist air meets cold glass. With single glazing, the inner pane is cold, so water runs down onto the sills and can lead to mould and rotting frames. Double glazing keeps the inside pane warmer, which reduces that build-up.

New frames also seal tightly, which stops the draughts that come through worn seals and gaps. Because sound has two panes and a sealed gap to cross, traffic, neighbours and street noise are noticeably softer.

Security and quality standards

Our double glazing windows are PAS 24 security rated, a standard that reflects the quality of our in-house manufacturing. Every window has a full Yale locking suite, so every lock and hinge on the window is Yale, down to the keeps and handles.

The suite includes heavy duty anti-hike shoot bolts, Vector excluders and Egress easy-clean hinges. Two panes of glass also make the window harder to break than single glazing.
