Why Replace Your Roof Windows?
Old or poorly installed roof windows can lead to...
-
Draughts, leaks, and heat loss
-
Condensation and mould growth
-
Higher energy bills and reduced comfort
-
Faded interiors due to poor UV protection
New VELUX windows dramatically improve thermal efficiency, reduce energy costs, and enhance your home’s look, feel, and function. You’ll also benefit from upgraded ventilation flaps, modern glazing options, and clean, bright white-painted or coloured aluminium finishes.
Not sure if it’s time to replace? Use the VELUX Window Configurator or check your data plate to find your current model.
