This energy efficient SIPs build, with a mechanical heat recovery ventilation system, air tightness, and uPVC double glazed windows, had BRANZ indoor air quality testing, carried out by their Senior Building Environment Scientist. The homeowner shared the results with us…..fine particulate matter, carbon monoxide, formaldehyde and carbon dioxide all came back as ‘excellent’ demonstrating the high levels of indoor air quality achieved through using these key principles.

This was one of our earlier SIPs builds and is still performing as well now as it was when it was first built. The SIPs panels are great for easily achieving angles in the house such as the dormer windows and steep raking ceilings.
