Flat rooflights in Milton Keynes
Daylight from above, with less frame in view.
We supply and install aluminium flat rooflights for extensions, flat roofs, larger openings and walk-on areas. We check the opening, upstand, glass and whether the rooflight needs to open before it is ordered.
- Fixed and opening rooflights
- Survey checks the opening and upstand
- Glass specified around safety and comfort
Edge-to-edge glassNo raised perimeter frame above the glass
Fixed or openingManual and powered ventilation options
Typical 1.3 W/m²KOverall roof value across the range shown
Safety glassToughened or laminated inner pane by specification
Fixed or opening
Choose whether the rooflight only brings in light or also opens.
The fixed rooflight sits 63mm above the upstand. The opening version can use manual or powered operation and rises to 103mm, only 40mm higher than the fixed version.
Fixed flat rooflight
Choose this when daylight is the priority and the room already has enough ventilation. Water can run off the polished glass edge without a raised frame around it.
Opening flat rooflight
Choose this when the room also needs high-level ventilation. It opens up to 300mm using a manual winder or powered operation.
Opening and controls
Decide how you want the rooflight to open.
An opening rooflight can use a wall switch, remote control or manual pole. Powered versions can also add rain sensing and thermostatic control, so we need to confirm the controls and wiring before order.
Larger and walk-on openings
Some roofs need more than a single pane.
A multi-pane rooflight divides a larger opening into several glazed panels. A walk-on rooflight uses a heavier laminated glass build-up for balconies and other areas where people need to cross the glass.
For larger roof openings
Multiple panes reduce individual glass sizes while keeping narrow internal and external sightlines. The unit is normally delivered in one section with its fixing straps attached.
For pedestrian areas
Three laminated layers of 10mm toughened glass form the walk-on outer section. Clear, obscure, sandblasted and textured anti-slip finishes are available by specification.

Compare Sheerline S1 roof lanterns.
A roof lantern adds visible aluminium rafters and a raised shape above the roof. The separate roof lantern page shows all 13 S1 layouts.

Fenster have just completed a front door installation on my new property - fantastic job and strongly recommend! The online design tool is great, Perry back at HQ is brilliant as is his communication. Andy, who installed the door, is a top gent and professional. Will definitely be a returning customer.

Really happy with the service we received from Fensters Windows. Aaron and Shane turned up on time and were both really friendly. They explained any issues as they went along and talked us through the different options, which we really appreciated. They did a great job fitting our new back doors and cleaned up everything afterwards. We also paid exactly what we had originally been quoted, with no unexpected extra costs. Really pleased with our new doors and would definitely recommend Fensters Windows. Thank you Aaron and Shane!

We have used Fensters for years on a variety of glazing work, and 2 door installations. They are competitively priced and responsive. They take great care over measuring and specifying the work, giving you a clear quote so you understand what you are getting (thanks Perry!). The fitters are all extremely competent and personable. We had to replace our front door for accessibility reasons, they gave us confidence that our requirements would be met, reproduced the intricate leaded and stained-glass pattern of our old door, and did a quality fitting job (thanks to Johnnie and Shane!). In summary they are our go-to suppliers for all replacement and repair work.

I had an excellent experience with Fenster Glazing from start to finish. Nick Perry and David managed the initial quote to installation process seamlessly, keeping communication clear, honest, and completely stress-free. When it came to the actual fitting, Zac and Shane did a fantastic job with the installation, working efficiently and leaving everything spotless. The professionalism from the entire team was top-notch, and the final result looks brilliant. I highly recommend them.

Great service from Fenster Glazing, very happy with our new bi-fold door, glass door and windows (with built-in blinds) There was an issue with the wrong spec of glass provided to them from their supplier, so they had to temporarily board up a door and a window, but this was put right within a few weeks. Recommended, thanks.
