Affordable Roof Windows with Double Glazing for Your Attic

Are you looking for roof windows that provide comfortable lighting for your attic and good thermal insulation at a reasonable price? Choose roof windows with double glazing – a popular solution that combines functionality with economy. These windows consist of two panes of glass separated by a layer of noble gas (usually argon), making them a good choice for most attic rooms.

Advantages of roof windows with double glazing:

Good insulation values: Double-glazed roof windows offer good thermal insulation, protecting against heat loss in winter and preventing excessive heating in summer. Although their thermal insulation performance is lower than that of triple-glazed models, they are sufficient for most standard applications. In combination with a sun protection awning, they also effectively protect against excessive heating under the roof in summer.
Optimal lighting: The design of double-glazed roof windows ensures optimal incidence of light, creating a bright and pleasant atmosphere in the attic.
Attractive price: Double-glazed windows are usually cheaper than triple-glazed windows, making them an attractive option for price-conscious buyers.
Lightweight construction: Compared to triple-glazed windows, double-glazed windows are lighter, which can facilitate their installation and reduce the load on the roof structure.

When is it worth choosing double-glazed roof windows?

✅ For rooms that are rarely used, such as attics, drying rooms, or storage rooms.
✅ For rooms where the highest thermal insulation is not required.
✅ When the budget is limited.
