Reader’s question

"Can I install a roof window made with glass blocks? The window is 80 cm wide by 100 cm high. I would like it to be top hinged.”

Our recommendation

You can’t install openable roof window with glass blocks. Roof windows are exposed to extreme weather conditions; that’s why it is absolutely necessary that their construction should ensure waterproofing and thermal insulation.

The most appropriate and economic solution is roof windows of various types and materials in standard sizes.

There are hinged/tilting/swinging roof windows, depending on your needs and desires.

Roof windows have double glazing and they can be equipped with integrated shading (blinds, etc.), manually or powered operated.

They let in plenty of natural light and enable natural ventilation and sound proofing.
