Astroglaze Flat Fixed Laminated Glass Rooflight - Rooflights & Skylights

What is a fixed rooflight?

A fixed rooflight is a non-opening glazed rooflight designed to bring natural daylight into a building without providing ventilation. Because the unit is permanently sealed, it offers a simple and cost-effective way to brighten interior spaces where airflow is already provided by windows, doors, or other ventilation systems.

Fixed rooflights are often chosen for their straightforward design, low maintenance requirements, and ability to maximise natural light. They are available in a wide range of sizes, styles, and glazing options to suit both residential and commercial projects.

Where are fixed rooflights typically installed?

Fixed rooflights are most commonly installed on flat or low-pitched roofs and are widely used in both residential and commercial projects. They are a popular choice for extensions, loft conversions, garages, offices, and open-plan living spaces where the primary goal is to maximise natural daylight.

Because fixed rooflights do not open, they are best suited to spaces where ventilation is already provided by windows, doors, or a mechanical ventilation system. Common applications include kitchens, dining rooms, living areas, hallways, and stairwells, where additional daylight can help create a brighter and more spacious environment.

Can a fixed rooflight be installed on a pitched roof?

Yes, provided the rooflight is suitable for the roof's pitch and construction.

Many fixed rooflights are designed for flat or low-pitched roofs and require a minimum installation pitch or upstand height to ensure effective drainage. Installing a rooflight outside the manufacturer's recommended pitch range can affect weather performance and may invalidate warranties.

For steeper roof pitches, purpose-designed pitched rooflights or roof windows are often the most appropriate solution, as they are designed to manage rainwater runoff and integrate correctly with pitched roofing materials. If you are unsure which product is best suited to your roof, our team can help identify the correct specification.

Are fixed rooflights cheaper than opening ones?

Generally, yes. Fixed rooflights have a simpler design than opening rooflights, with no hinges, handles, actuators, or control systems. This typically makes them less expensive to manufacture, purchase, and install.

For projects where additional ventilation is not required, a fixed rooflight can provide a cost-effective way to increase natural light while keeping maintenance requirements to a minimum.

However, overall costs will also depend on factors such as size, glazing specification, frame material, and installation requirements. If ventilation is likely to be needed, it is often more practical and economical to specify an opening rooflight from the outset rather than upgrade later.

How do you clean a fixed rooflight?

Fixed rooflights should be cleaned periodically to maintain their appearance and maximise light transmission. Internal surfaces can usually be cleaned with a soft cloth and a non-abrasive glass cleaner, while external surfaces should be cleaned using a soft brush, sponge, or squeegee with clean water or a mild cleaning solution.

Avoid abrasive pads, harsh chemicals, or solvent-based cleaners, as these can damage glazing surfaces, specialist coatings, seals, or frame finishes.

For rooflights installed at height, safe access equipment should always be used, and professional cleaning may be advisable where access is difficult.

Some rooflights are available with self-cleaning glass coatings that help break down organic dirt and improve rainwater wash-off. While these coatings can reduce maintenance requirements, occasional cleaning will still be necessary to keep the glazing performing at its best.
