How we approach commercial & industrial rooflights in Castle Douglas
Our commercial & industrial rooflights service in Castle Douglas covers rooflights for warehouses, schools, offices and retail units. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. Commercial & industrial rooflights suit industrial roofs with tired or fragile rooflight sheets.
We work across Dumfries and Galloway, including Castle Douglas, and in neighbouring towns such as Kirkcudbright and Dumfries. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Continuous barrel-vault rooflights
- Mesh or grilles under fragile areas
- Modular glass rooflights
- GRP or polycarbonate in-plane rooflight sheets
- Polycarbonate domes
- Daylight that reduces daytime lighting
- Smoke-vent options where needed
Things we check at survey
- Fragile rooflights are a known fall hazard — work at height must be planned
- Non-fragility classification should be confirmed for new products
Building control and safety duties in Castle Douglas
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 Scotland, the non-domestic Technical Handbook (section 6) sets the energy standards for rooflights; we supply the manufacturer's data for the building warrant. Fire classification of rooflight materials near boundaries is checked at specification.
