Commercial & industrial rooflights in Thamesmead: what is involved?
For Thamesmead homes and buildings we offer commercial & industrial rooflights: rooflights for warehouses, schools, offices and retail units. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of commercial & industrial rooflights for warehouses, schools, offices and retail units.
We work across Greater London, including Thamesmead, and in neighbouring towns such as Barking and Welling. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Thamesmead
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- GRP or polycarbonate in-plane rooflight sheets
- Modular glass rooflights
- Smoke and natural ventilation vents
- Barrel vaults, ridge lights and modular glass
- Daylight that reduces daytime lighting
What to check first
- Fire performance of rooflight materials matters near boundaries
- Non-fragility classification should be confirmed for new products
Building control and safety duties in Thamesmead
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.
See our building regulations guide for U-values, glazing limits and self-certification.
