These are the ideal choice for an overhead window that provides flexibility and thermal efficiency. ALTHERM roof windows minimise condensation, and help retain interior heat and comfort levels.

Two options are offered – fixed windows or hinged on one side to allow opening for ventilation when required. The ALTHERM roof window has a thermal break in both the frame and sash, to ensure maximum thermal efficiency in the closed position. A key attribute is versatility – roof windows can be made in a wide range of sizes, customised to the required dimensions. They are also capable of dual colour, allowing a match with both interior schemes and the roof colour.
