How we approach commercial & industrial rooflights in Mangotsfield
For Mangotsfield 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
Mangotsfield sits about 2 km from Fishponds and 4 km from Kingswood, and we cover the whole BS16 postcode district and the roads in between.
Choices for your Mangotsfield project
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- GRP or polycarbonate in-plane rooflight sheets
- Smoke and natural ventilation vents
- Polycarbonate domes
- Replacement of discoloured or fragile sheets
- Smoke-vent options where needed
Before you order: points to check
- Fire performance of rooflight materials matters near boundaries
- Asbestos surveys may be needed on older roofs
Regulations for commercial & industrial rooflights in Mangotsfield
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
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.
