Product Description

Bring more natural light into your home

Roof domes offer a whole host of possibilities when installed on your property. A fantastic source of natural light through your flat roof, the dome only comes in three skin thicknesses that are suitable for different installations.

All of our domes are thermoformed from UV protected, co-extruded polycarbonate sheet and each dome has a minimum 3mm thick glazing. Polycarbonate itself is virtually unbreakable and has an impact strength up to 250 times greater than glass.

By purchasing this dome only, an upstand must be constructed on-site to the exact dimension shown above or the dome can be installed onto an existing upstand.

What is the best skin thickness for you?

  • Single skin - Recommended to only be used in uninhabited areas such as a garage, corridor, storage room (U-value: 5.36W/m2K)
  • Double skin - Recommended to be used when replacing a dome, ie like for like replacement (U-value: 2.68W/m2K)
  • Triple skin - Must be used on new builds to comply with building regulations (Part L Thermal Performance) (U-value: 1.78W/m2K)
  • Quadruple skin - Recommended for best thermal performance (U-value: 1.24W/m2K)

How secure are the roof domes?

Unique to our domes are the high-security screwbolts and fixings that come supplied as standard with all dome only products. Once installed, the fixing cannot be removed using common tools. The screwbolt provides a 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.


When installed, these domes are expected to exceed the life of the roof covering and will not rust or be affected by atmospheric pollution. They are maintenance free once installed. The domes are guaranteed against the effects of defective design, materials or construction for ten years, subject to certain conditions. 

Dimensions shown are builders overall upstand size. Dome only itself is 60mm larger.
