Fixed Flat Glass Rooflights

What Are Fixed Flat Roof Skylights?

Fixed flat roof skylights are non-opening rooflights that are permanently sealed. They are engineered to:

• Maximise daylight without heat loss or drafts
• Create bright, welcoming interiors
• Offer a low profile roof design
• Deliver strong weather resistance

Because they don’t open, fixed skylights are a great choice for areas where only natural light is needed, such as corridors, living rooms, kitchens, stairwells and commercial spaces.
