The latest design innovation from Fakro provides further proof of the extent to which roof window technology is changing. The DXW flat roof window has a wear-resistant, anti-slip surface which enables it to take constant foot traffic, even in wet weather. Designed in answer to feedback for a product that can be fitted flush within the roofline, its strengthened sash, frame and laminated glazing make it ideal for use on roof terraces.

The DXW design is highly contemporary in style and combines a strong visual aesthetic with the highest technical performance. Its large glazing area also ensures that the maximum amount of natural light is brought to the living space below – from an interior perspective the inner surface is white.

Constant stresses and point loading present no threat to the glazing unit, the U-value of which is an impressive 0.5W/m²K. The multi-chamber PVC frame is filled with polystyrene insulation to bring its thermal properties within the requirements of Passivhaus construction. Eight standard sizes are available, from 600 x 600mm – see it being put to the test.
