What are Skylights / Rooflights?

Industrial skylights or rooflights are roof windows that follow the identical angle of the roof. These are made to fit the profile of the roof covering. Skylights are fabricated from a (GRP) fibreglass without colouring, making it transparent, permitting light to penetrate into your workspace.

Industrial profile skylights or rooflights are an effective manner of lighting for your commercial or industrial environment without the need for electricity. Skylights/roof lights are utilized in modern-day construction plans more than ever, with the regular rise of utilities. (GRP) products last much longer as the products continue to advance.

High-quality (GRP) these days can last as long as 35 years as a rooflight before it indicates any symptoms of deterioration or breaking down because of the regular assault from the ultraviolet rays brought on by the sun. So, if you’re in need of Industrial or commercial skylight and rooflight replacements, look no further than Maldon Roofing.

How are Industrial Skylights & Rooflights Fitted?

Rooflights and or Skylights are fitted with a simple process, access to the roof is always required and should only be carried out by professionals. This is because working at height can be dangerous without the proper knowledge of how to harness yourself or knowing the supported areas on the Corrugated roof to stand.

First, the old skylight or rooflight is removed, which is done by removing the old fixings. Fixings can vary depending on the material of the purlin. Purlins are usually made of steel or wood, but also come in concrete. Once the fixings are removed, the old Skylight / Rooflight is taken out, and a new one is ready to be installed.

New Skylight / Rooflight Installation can sometimes be tricky, depending on the material of the other corrugated sheets, the Skylight / Rooflight is placed under the sheet above and the sheet below. Once in place, a sealant bead is applied to ensure a proper seal, and then new fixings are screwed or hooked onto the purlins. To complete the work, any holes left behind from previous fixings are sealed and covered with flashing and/ or liquid coating systems.

Fire Ratings: Class 0, Class 1, and Class 3 GRP Skylights

Fire performance is a key consideration when specifying GRP (Glass Reinforced Plastic) skylights in industrial and commercial buildings. In the UK, BS 476 is the main fire testing standard used to assess the surface spread of flame and fire propagation characteristics of construction materials, including GRP rooflights.

Class 0 GRP Skylights

Definition: Class 0 is the highest UK fire rating under BS 476. It is not a test in itself but a composite rating based on results from:

- BS 476 Part 6 (fire propagation)
- BS 476 Part 7 (surface spread of flame)

Fire Performance:

Very low flame spread.
Minimal contribution to fire growth.
Suitable for use in most areas of industrial and commercial buildings, including corridors, escape routes, and large-scale factory settings.

Application: Class 0 GRP skylights are ideal for high-risk areas or buildings that must meet stringent fire safety standards under the Building Regulations.

Class 1 GRP Skylights

Definition: Based on BS 476 Part 7, Class 1 indicates a low surface spread of flame, but without the full performance needed to achieve Class 0.

Fire Performance:

Good resistance to flame spread.
Acceptable for many standard industrial and commercial roofing applications.

Application: Class 1 GRP skylights are commonly used in areas with lower fire risk or where additional protection (e.g., fire barriers or sprinklers) is in place.

Class 3 GRP Skylights

Definition: Also rated under BS 476 Part 7, Class 3 materials have a moderate to high surface flame spread.

Fire Performance:

Slower to ignite than non-rated products, but may support flame spread once burning.
Does not meet the higher safety criteria of Class 1 or Class 0.

Application: Typically used in agricultural or non-regulated settings. Not recommended for most industrial buildings subject to Building Regulations or insurance restrictions.

Summary Table

Fire Rating	Standard	Flame Spread	Typical Use
Class 0	BS 476 Parts 6 & 7	Very limited / non-combustible	High-risk or regulated industrial areas
Class 1	BS 476 Part 7	Low flame spread	General industrial and commercial use
Class 3	BS 476 Part 7	Moderate flame spread	Agricultural or low-regulation use

Key Considerations

Building regulations in the UK often require Class 0 fire-rated materials for rooflights in protected zones, escape routes, and other critical areas.
Insurance providers may also require higher fire ratings, especially in high-value or high-risk industrial properties.
Always combine fire performance with other considerations like impact resistance, UV stability, and weight when specifying GRP skylights.

If you’re working on a project and need help selecting the right fire-rated GRP skylight, feel free to ask — I can help tailor the specification to meet safety, regulatory, and budget requirements.
