A quality made thermoformed opening rooflight designed to make the maximum use of natural lighting whilst offering ventilation by manually opening 300mm on a spiral drive rod. Our domes are offered in a huge range of shapes, sizes and glazing options to comply with almost any specifier requirements.

The Roof Domes are thermoformed from co-extruded UV stable polycarbonate and are available in single, double or triple skin construction. Each glazing layer is 3mm thick. All glazing is tested and certified according to EN 1873:1200 J, and ACR(M): 001: 2005 Class B.

The Domes are tested to stringent standards and are suitable for use on most flat roofs, including single ply, holt melt, felt, asphalt, lead, liquid applied and GRP. They are supplied with our insulated curbs but can also be installed on a builders curb.

  • A range of alternative upstands to accommodate new roof insulation (please call to discuss)
  • Patented high security screwbolt fixing
  • Our curb provides very neat detailing
Please note, although this product is on a fast leadtime, it is assembled to order as a bespoke item and any exchange or return of product will incur a 25% restocking and disassembly charge
