House Extensions FAQ

Fire Performance Rating

Building regulations require 30 minutes fire resistance for housing. Kingspan’s independent fire testing of Kingspan TEK® build system achieved 77 minutes.

How SIPS House Extensions lower energy costs over a traditional extension?

With a U-value of up to 0.10 W/m2K, SIPS Panel Building Systems are the most thermally efficient, insulated wall construction available today and is now specified as the first step in achieving Net-Zero carbon housing.

How SIPS House Extensions save internal space?

SIPS Panel Building Systems have a superior U-value of up to 0.10 W/m2K with a total wall thickness of 275.5 mm. To achieve an equivalent U-value using traditional methods of construction the wall would have to be 453 mm thick.

What disruption will there be?

All house extensions are pre-assembled, factory-engineered modular structures that are delivered, ready-made, directly to site for assembly meaning that they are not subject to site weather conditions.

This results in fewer trades being involved in the construction of the extension and minimises disruption to the homeowner.

SIPS House Extensions very speedy to erect, meaning that the construction can be walled and roofed quicker than with other forms of construction, making it easier and quicker to knock-through.
