Product Description

Introducing the domed flat roof window

At Sterlingbuild, our range of domed flat glass windows have been created to offer a very high quality product for very good value for money. The domed flat roof window incorporates a roof dome in single skin (as standard), and a double glazed glass unit securely formed in a PVC frame.

By letting in natural daylight through your flat roof, you incorporate a real WOW factor into your home. This will add value to your property as well as reducing its carbon footprint.

Flat roof windows provide up to three times more daylight than equally sized vertical windows.

With a U-value as low as 0.64W/m2K why not upgrade your flat glass window dome to double, triple or even quadruple skin and save even more energy and even more on your bills.

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.

The ultimate sound insulation

Our domed flat glass windows provide excellent sound insulation from rain and hail which makes the domed flat glass window the ideal product for installation in practically any room. Sleep through the stormy nights or enjoy an evening of entertainment viewing in your living room. You will not be disturbed by the outer elements.

Roof domes offer a sound insulation level of 35 Rw dB.

How secure are the roof domes?

Unique to our domed flat glass windows 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

Even though you've chosen the fixed unit, you can have a controllable trickle vent built into two sides of the upstand or choose the 300mm high upstand with controllable rotating vents. The ventilation can provide 8000mm2 ventilation area which assists with Building Regulations compliance.

What is a warm roof construction?

Warm roof construction is the adding of insulation to the top of the roof deck which then allows for less heat loss. For any extension, Building Control are enforcing warm roof constructions, and the 300mm high upstand is ideal for any warm roof construction.

Half of the uptand is hidden in the insulated roof space and the other 150mm seen on the roof complies to building regulations.

Performance

When installed, the domed flat glass windows 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.
