What are commercial & industrial rooflights?
Commercial & industrial rooflights in Clwyd means rooflights for warehouses, schools, offices and retail units. Every quote follows a survey of the roof and the room below.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting.

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.
