If you want the cleanest, most uninterrupted view of the sky from inside your home, the Bonded Flat Roof Light is the one to choose. The glass is structurally bonded directly to the aluminium frame, which means there is no visible framework from inside the room at all. What you’re left with is a flush, seamless panel of glass in your ceiling that draws daylight in and makes a room feel genuinely different.
It’s a premium product that suits people who care about the finish as much as the performance, and it’s one we’ve been fitting across Surrey to consistently impressive results.
I have been using Sheerwater Glass for many years and the service the team provide is excellent. Kairo and Cliff did a fantastic job fitting my windows, despite the awful weather they had to endure. They left the house clean and tidy. Thank you Sheerwater Glass for another good job.
The reason the Bonded Flat Roof Light looks so clean from inside is in the construction. The glass unit is structurally bonded to the fully thermally broken aluminium frame, which eliminates the need for any visible glazing bars or beading from below. From inside the room you see nothing but glass, which creates a sense of space and light that a framed rooflight simply cannot replicate. The frame sits flush with the roof surface outside too, giving a sleek, contemporary finish from every angle.
It’s worth knowing that because the glass is structurally bonded to the frame, the two cannot be separated. If a pane ever fails, the whole unit would need replacing rather than just the glass. For most homeowners that’s a straightforward trade-off for the finish you get in return. If the ability to replace individual panes matters more to you, our Endure Flat Roof Light is worth a closer look.
Without a frame in sight from inside the room, the Bonded Flat Roof Light creates something genuinely special. On a clear day it feels less like a rooflight and more like a perfectly framed window to the sky. It’s the kind of finish that draws comments from everyone who sees it.
The fully thermally broken profile achieves U-values from 1.0 W/m²K, which is outstanding for a rooflight of any size. That means your home stays warmer in winter and cooler in summer, with less energy needed to maintain a comfortable temperature.
Light from above travels further into a room than light from a window, and the frameless design means nothing interrupts it. Whether it’s morning sun or soft afternoon light, a room with a Bonded Flat Roof Light feels brighter and more welcoming throughout the day.
Rated Class 9A for water tightness and Class A4 for wind resistance, the Bonded Flat Roof Light is built to perform in all conditions. With a minimum fall of 5 degrees, water drains away naturally and reliably every time it rains.
The flush glazed external finish sits neatly within the roof line with no visual bulk from outside, while the frameless internal finish creates a contemporary, uncluttered look from below. It works beautifully in both modern and traditional homes.
Available in sizes up to 3000mm x 2000mm as standard, with larger sizes available on request. A walk-on glazing option and motorised electronic opener are also available, making it a genuinely versatile solution for a wide range of project

A bonded flat roof light is a rooflight where the glass is structurally bonded directly to the aluminium frame, creating a completely frameless finish from inside the room. There are no visible glazing bars or beading from below, just a clean, uninterrupted panel of glass in your ceiling. It’s the premium choice for homeowners who want the most refined finish possible.
The Bonded Flat Roof Light achieves U-values from 1.0 W/m²K, thanks to its fully thermally broken profile. That’s an exceptional level of thermal performance for a rooflight and means your home stays comfortable year round without your heating having to work harder to compensate.
The Bonded Flat Roof Light is available in sizes up to 3000mm x 2000mm as standard, with larger sizes available on request. When we visit to survey your roof we’ll confirm the right size for your opening and advise on anything that needs to be considered beforehand.
Because the glass is structurally bonded to the frame, the two cannot be separated. If a pane ever fails, the whole unit would need replacing rather than just the glass. For most homeowners that’s a straightforward trade-off for the frameless finish it delivers. If replaceable glass matters more to you, our Endure Flat Roof Light is designed with exactly that in mind.
Yes. A motorised electronic opener is available as an option on the Bonded Flat Roof Light, which allows you to ventilate the room without any manual effort. It’s a particularly useful addition in kitchens, orangeries and extensions where ventilation is important.
