How we approach commercial & industrial rooflights in Whitehaven
Thinking about commercial & industrial rooflights in Whitehaven? The short answer: rooflights for warehouses, schools, offices and retail units. The longer answer depends on your roof, which is why we survey before we price.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Think of commercial & industrial rooflights for warehouses, schools, offices and retail units.
Whitehaven is around 57 km from Carlisle, and we survey and fit throughout that part of Cumbria, including the CA28 district.
What you can choose
- Polycarbonate domes
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Mesh or grilles under fragile areas
- Continuous barrel-vault rooflights
- Barrel vaults, ridge lights and modular glass
- Fall-protection planning included
Things we check at survey
- Asbestos surveys may be needed on older roofs
- Fragile rooflights are a known fall hazard — work at height must be planned
Rules and responsibilities in Whitehaven
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. 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.
