Professional Secondary Glazing across the South East

Secondary glazing involves fitting a slim-profile inner window on the room side of your existing frame, creating a highly effective insulating cavity. It reduces heat loss by up to 60 per cent, dramatically cuts noise intrusion and prevents condensation — all without changing the external appearance of your windows.

It is the most practical solution for listed buildings and conservation areas where original windows must be retained, and is also widely chosen for Victorian and Edwardian sash windows where replacement would compromise character. Our systems open and close independently and are barely visible when fitted.

We install vertical sliding, horizontal sliding, lift-out and hinged secondary glazing panels in neutral finishes or colour-matched to your existing frames. Acoustic secondary glazing has become particularly popular for home workers and anyone living near a main road — the reduction in noise is immediate and dramatic.
