Description
Modular Flat Rooflight
Our frameless flat modular rooflight system offers a sleek, contemporary solution, ideal for residential applications.
Suitable for both flat and pitched roofs with an upstand, each unit features a fully thermally broken aluminium frame and is designed for easy on-site assembly and installation.
Instead of bulky metal supports, glazing panels are joined and weather tightened using special structural silicone, creating a clean, seamless appearance with uninterrupted views and a modern, minimalist finish.
Rooflight Feature
-
Designed for Flat and Pitched Roofs
Built to suit a variety of roof types, our modular rooflight combines modern aesthetics with reliable performance. -
Thermally Broken Aluminium Frame
The fully enclosed frame improves energy efficiency and reduces the risk of leaks and edge damage, unlike exposed glass alternatives. -
Wall Facing Flexibility
Our rooflights can be wall abutted up against one, two, or even three vertical walls. Ideal for tight spaces, L-shaped extensions, or wraparound designs -
Wide Range of Glass Options
Choose from Low-E, solar control, obscure, tinted, or anti-slip glass. Each tailored for performance, privacy, or style. -
Custom Modular Layouts
Ideal for larger spans, corners, or complex roof shapes—made to order and connected on-site for a seamless finish.
How To Measure Flat Rooflight
When selecting your rooflight size, it’s important to base it on the external weathered kerb dimensions.
Our rooflights are then manufactured with a built-in 10mm tolerance within the frame to ensure a precise and secure fit.

Benefits of Modular Rooflight
This customisable solution eliminates the challenges of transporting and installing large, single piece rooflights in confined spaces.
By dividing larger rooflight designs into modular parts, fabrication, transport, and installation become easier and could lead to lower rooflight costs.
The laminated glass provides overhead protection, preventing glass from falling if broken, ensuring safety for those below and protecting furniture from damage.
While framed skylights may have a higher upfront cost due to their construction and energy efficiency features, they are generally more cost-effective in the long run.
The sleek design of the fixed rooflight includes a slim powder-coated frame and a flush glass panel, maximising the amount of natural light entering the room.
Frequently asked questions
Do you offer a site survey before installation?
Yes, we provide site surveys for more complex or custom installations to ensure accurate measurements and assess structural conditions. This helps us deliver a perfect fit and smooth installation process.
What information do you need to provide a quote?
To provide an accurate quote, we typically need the approximate dimensions, roof type (flat or pitched), preferred glass specification, and project location. Photos or drawings are helpful too.
What are the lead times for manufacturing and delivery?
Lead times vary depending on the complexity of the rooflight, but standard units typically have a lead time of 3–4 weeks. Custom or oversized units may take slightly longer.
Can you help with planning or structural requirements?
While we don’t manage formal planning applications, our technical team can provide detailed information on glass load, unit weight, and recommended fixing methods. This helps architects, builders, and engineers specify the correct structural support for our rooflights.
