Fixed Roof Domes

The Professional Choice for Fixed Flat Roof Domes

When it comes to flat roof daylighting, a fixed roof dome remains one of the most reliable and versatile options. Unlike opening variants, the seamless, non-opening design of a fixed flat roof dome offers enhanced weather tightness and structural integrity, making it an ideal choice for hallways, stairwells, and large commercial spaces where consistent overhead lighting is the primary objective.

Why Choose a Fixed Roof Dome?

For many architects and contractors, the decision to install a fixed unit is driven by three core factors:

• Security: With no moving parts or external hinges, these units provide a robust barrier against unauthorised entry.
• Thermal Performance: Our fixed domes are available in double, triple, and even quadruple skin polycarbonate, helping to maintain U-values and reduce heat loss in accordance with Part L Building Regulations.
• Maintenance-Free Longevity: Constructed from high-quality, UV-stabilised polycarbonate, our domes are designed to resist yellowing and brittle fracture, ensuring decades of performance with minimal upkeep.

Finding the Right Fit for Your Project

Selecting the correct fixed flat roof dome depends on your existing roof structure. We provide “dome only” options for refurbishment projects where the original kerb remains functional, as well as complete units with splayed or vertical upstands for new-build installations. Choose from clear glazing for maximum light transmission or opal finishes for diffused light and increased privacy.

If you require technical assistance regarding U-values, fire ratings, or bespoke sizing, our industry-experienced team is on hand to ensure you specify the perfect daylighting solution.
