Fabrication record

What aluminium flat rooflights can actually be built to

These are the limits the factory works to, taken from the fabrication data for the system we make this product in. Premium routes in the same family reach better thermal and acoustic figures than the ones below, and are quoted where the project calls for them. Either way this is the envelope, not a quotation: the achievable figures for your opening are confirmed against your drawings and a survey.

How we specify

The right product route is chosen per project

Exact specification (U-value, sizes, weights, security class, finish) is confirmed per project at quote, selected to suit the trade brief.

It means you lead with the outcome: light, security, clean sightlines, usable openings, buildable details and a specification that suits the drawings.

More on how routes are specified: security and PAS 24 routes and energy efficiency and U-values.

Common questions

What U-value does a flat rooflight reach?

Thermally broken aluminium flat rooflights reach whole-unit U-values from 0.9 W/m²K where specified, with double or triple glazing. Because a rooflight faces straight up it sees more sky and more solar gain than a window, so the glass specification carries most of the result. We confirm the figure for your unit at quote.

Are your flat rooflights fixed, or do they open?

The flat rooflights we supply are fixed units, quoted from drawings. That keeps the sightline low and the detail simple where the rooflight is there for daylight rather than ventilation. If the room needs ventilation as well, tell us at quote and we will spec it into the wider opening schedule instead.

What do you need to quote a flat rooflight?

The structural opening size, the kerb detail and the roof build-up, then the finished size, glass and finish you want. Kerb detail matters most - it sets how the unit sits, how it weathers and the finished internal sightline. Send those through quote.

Can I get solar control, privacy or safety glass in a rooflight?

Yes. Solar control glass is worth specifying on a south-facing flat roof, privacy interlayers where the rooflight is overlooked, and laminated or toughened panes where the build-up or the room below calls for it. Tell us the thermal target and any solar-control, privacy or safety-glass requirement and we confirm the make-up at quote.

Can I order a flat rooflight on its own?

Flat rooflights are supplied as a package add-on to a wider trade glazing order rather than as a single-item purchase. Add them to the same schedule as the doors and windows for the project and they are quoted, fabricated and delivered together. Send the schedule through quote.
