Secondary Glazing Benefits
Secondary glazing offers the most effective sound insulation – significantly outperforming double glazing. From noisy roads to noisy kids, our windows can reduce noise levels by up to 80%
Substantially improves the thermal insulation of existing single-glazed windows – reduces heat loss through the window by around 65% – around 10% more than double glazing.
Secondary windows offer an affordable, discreet, highly effective solution to enhancing building security. No external access is required, ideal for multi-storey buildings.
