Commercial & industrial rooflights in St Albans: what is involved?
Thinking about commercial & industrial rooflights in St Albans? 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In St Albans, as anywhere, commercial & industrial rooflights are the usual choice for industrial roofs with tired or fragile rooflight sheets.
Jobs in St Albans are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your St Albans project
- Modular glass rooflights
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Smoke and natural ventilation vents
- GRP or polycarbonate in-plane rooflight sheets
- Daylight that reduces daytime lighting
- Barrel vaults, ridge lights and modular glass
Things we check at survey
- Fire performance of rooflight materials matters near boundaries
- Non-fragility classification should be confirmed for new products
Building control and safety duties in St Albans
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.
