Double glazing

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

Advantages of Double-glazed Roof Windows:

Good insulation properties: Double-glazed roof windows offer good thermal insulation, protecting against heat loss in winter and overheating in summer. While they don't match triple-glazed windows in terms of insulation, they are sufficient for most standard applications.
Optimal lighting: The design of double-glazed roof windows ensures optimal natural light inflow, creating a bright and pleasant atmosphere in the attic.
Attractive price: Double-glazed windows are generally cheaper than triple-glazed ones, making them an appealing option for cost-conscious buyers.
Lightweight construction: Compared to triple-glazed windows, double-glazed windows are lighter, which can make installation easier and reduce the load on the roof structure.

When to Choose Double-glazed Roof Windows?

✅ For rooms used less frequently, such as attics, drying rooms, or storage spaces.
✅ For rooms where the highest thermal insulation is not required.
✅ When the budget is limited.
