The Main Factor in Home Energy Performance is creating a continuous Thermal Envelope w/ True R Value without- air infiltration or air bypasses!
- R- Value is simply a measure of resistance to heat flow. Air moving thru insulation reduces R- Value!
- Air Infiltration is through penetrations as small as a pin & driven by The Stack Effect, pressure differences, or wind.
- Air Bypasses are bigger holes- w/ the building not connecting continuously.
