Build Tight & Ventilate Right!
A thermal bridge is created when materials that are poor insulators come in contact, allowing heat to flow through the path created. Insulation around a bridge is of little help in preventing heat loss or gain due to thermal bridging; the bridging has to be eliminated, rebuilt with a reduced cross-section or with materials that have better insulating properties, or with an additional insulating component (a thermal break).

This thermal image clearly shows how a stick built home allows heat to escape through the framing of the house. The vertical lines in this image show exactly where the wood studs come in contact with the exterior sheeting.

An inERGY Home built with steel studs and polystyrene foam insulation, elminates the thermal bridge commonly found in wood framed housing.

Light gauge steel framing allows for a tighter, non shifting envelop in the buildings insulation system over conventional building practice. This assures maximum energy efficiency.
Melting frost and snow is the easiest way to see the effects of thermal bridging. Imagine money going through the roof and walls and evaporating into the air.

Notice how the heat is seeping out of this roof and melting the frost! They will be looking forward to a huge electricity bill!

This is an inERGY Home that is wrapped tight and ventilated right.

State of the art insulation techniques with steel framing will render thermal bridging null and void. Build tight and ventilate right for efficiency and healthy indoor air quality.
