What are commercial & industrial rooflights?
Our commercial & industrial rooflights service in West Sussex covers rooflights for warehouses, schools, offices and retail units. We survey every job before fixing the price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice.

Planning and building rules in England
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.
