What do commercial & industrial rooflights in Horsham involve?
Thinking about commercial & industrial rooflights in Horsham? 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Think of commercial & industrial rooflights for industrial roofs with tired or fragile rooflight sheets.
Neighbouring towns include Crawley (12 km) and Horley (17 km). We offer a survey date when we reply to your enquiry.

Regulations for commercial & industrial rooflights in Horsham
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.
