The complete package for the best price
When buying the opening polycarbonate dome, you're getting the whole package. The PVCu upstand and the dome with thickness of your choice. The only thing you need onsite is flashing and this is whatever your roof material is, be it GRP, felt or rubber for instance.
The ECO upstand
Made from extruded PVCu, the ECO upstand is the most thermally efficient, environmentally friendly rooflight upstand yet. Built with a strong nine-walled cellular structure, this thermally broken upstand also has a groove built into the upstand to allow for a smooth plasterboard finish. The ECO upstand has an overall U-value of 0.92W/m2K. Pre-finished white internally, it gives a perfectly finished design suitable for any interior.
Thickness - 50mm
Height - 160mm
What is the best skin thickness for you?

- Double skin - Recommended to be used when replacing a dome, ie like for like replacement (U-value: 2.68 W/m2K)
- Triple skin - Must be used on new builds to comply with building regulations (Part L Thermal Performance) (U-value: 1.78 W/m2K)
- Quadruple skin - Recommended for best thermal performance (U-value: 1.24 W/m2K)
How secure are the roof domes?
Unique to our opening roof domes are the high-security screwbolts, supplied factory fitted as standard to all units. 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.
Keeping your rooms chilled
An opening flat roof dome offers more ventilation as well as natural daylight to your living space. You can also have a controllable trickle vent built into two sides of the upstand for even more ventilation. The roof domes will open up to 400mm for ventilation and the barrel bolt can be removed to allow the dome to open fully if you ever need to get onto the roof. The ventilation can provide 8000mm2 ventilation area which assists with Building Regulations compliance.
The manual spindle operation can be operated by a winding rod if the unit is out of reach.
When installed, the opening 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 10 years, subject to certain conditions.
