UV Protection With uPVC Windows
Our exterior windows are manufactured using an exclusive, 100% lead free uPVC powder compound. These uPVC windows are designed to endure prolonged exposure to sunlight. The compound offers excellent resistance to impact and fading, ensuring that the windows do not crack, discolour, blister, or warp, while remaining entirely maintenance free.
Weather Proof Windows for Homes
Advanced triple weather stripping provides a superior seal and effective leak protection through an integrated locking system, secured at the corners, and attached to the window frame. This design ensures consistent locking at the top corner of the window, regardless of its height. Corners are typically the most vulnerable points in structural integrity and air infiltration tests.
