A cost-effective daylighting solution using continuous polycarbonate domes or pyramids to provide bright, natural light across large roof areas

Joined domes and pyramids

Suitable for:

  • flat or low-pitch roofs up to 15°
  • projects that require continuous daylighting, offering multiple domes or pyramids joined together to form long rooflight runs
  • industrial, commercial and educational buildings, where natural lighting and economy are key
  • new build and refurbishment projects, with compatibility across all standard roof coverings, including EPDM, PVC, bitumen and GRP
Flat roof with pyramid-shaped skylights and terraced houses in the background.
Dome rooflights allow light to enter from more angles throughout the day compared to flat panels, so the interior space receives a more consistent spread of daylight

Product details

Our joined roll-joint dome and pyramid systems offer a reliable, economical way to introduce continuous natural daylight into large-area roofs. Using robust polycarbonate glazing, the design provides bright interior lighting, weather-tight joints and simple installation at an affordable cost.
