Dome Lid Only - Requires Builders Upstand

Why Choose a Polycarbonate Rooflight Dome Lid?

• Build Your Own Upstand: Designed for use with a builder‑supplied upstand, giving you flexibility in roof detailing and integration.
• Strong & Weather‑Resistant: Polycarbonate is durable, tough and able to withstand rain, hail and temperature changes, perfect for UK conditions.
• Lightweight & Easy to Handle: Easier to manoeuvre than glass alternatives, ideal for retrofit and new build sites.
• Excellent Daylight Transmission: Delivers bright, even natural light to interior spaces, enhancing comfort and visibility.

• Installer Flexibility – Perfect for contractors who prefer to build or source their own upstand, or who are working within bespoke roof detailing requirements.
