What are commercial & industrial rooflights?
Commercial & industrial rooflights in West Glamorgan means rooflights for warehouses, schools, offices and retail units. Every quote follows a survey of the roof and the room below.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen.

Planning and building rules in Wales
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 non-domestic buildings in Wales, Approved Document L sets limiting U-values for rooflights and roof ventilators; we supply the manufacturer's data for the building control submission. Fire classification of rooflight materials near boundaries is checked at specification.
