High quality thermoformed rooflights designed to make optimum use of natural light.  The Loft Shop domes are offered in a wide range of sizes, shapes and glazing options to meet virtually any specifier and client requirements.

Roof dome only, measurements stated are external builders kerb dimensions, see image (dimension B).  The kerb needs to only be made 50mm thick. 


Key features include

  • Choice of dome, pyramid or trapezoidal shape
  • Polycarbonate double skin
  • To BS 476: Part 3 AA rated
  • To BS 476: Part 7 Class 1
  • Compliant with HSG33 recommendations
  • Patented high security screwbolt fixing

The Loft Shop roof domes are thermoformed from UV protected, co-extruded polycarbonate sheet and are available in single, double, triple quad skin or Eco multiwall construction.

Polycarbonate domes use a minimum 3mm thick glazing and have been tested and certified according to EN 1873: 1200 Joules, and ACR(M): 001: 2005 Class B.

Loft Shop roof domes are tested to the highest standards and are proven suitable for use on most flat roofs, including single ply, felt, hot-melt, asphalt, liquid, GRP and lead.  They are normally specified with our proprietary curbs but can also be installed on existing builder's curbs.

Higher security, access and ventilation options are available.

High security screwbolts

Unique to our roof domes, these are patented high security screwbolts, supplied factory fitted as standard to all units.  Once installed, the fixing cannot be removed using common tools.  The screwbolt provides high level of resistance to tampering or forced entry.  The fixing screw or bolt is sleeved within the body of the screwbolt which avoids pressure being exerted on the rooflight glazing as the fixing is tightened.  This virtually eliminates the risk of stress fractures caused by over-tightening.
