...heating. Heat Recovery Ventilators (HRVs) are an essential component of any air-sealed high performance home, bringing in fresh air and removing moisture. An HRV uses the heat in stale exhaust air to warm incoming fresh air. Until now, this has meant a centralized heat transfer core and a network of ducts feeding and...

...heat, the paint offers an effective 'boost' to the R value. And they include some very convincing sounding stuff about heat transfer and thermal resistance for good measure, including the percentages of heat that you will save off your current bill. This is not the first time that the laws of physics have been cherry-p...

Our top tips for buying high-performance windows

...heat comes in and how much goes out. Low E coatings on windows will reduce heat loss by reflecting infrared heat back into your home in winter while also reflecting heat back out in summer. On the down side, they can also reduce heat gain when you want it, during the heating season. So a little thought should go into c...
