On this 100% of us can all agree. We love air!!! Think not? Then hold your breath for 3 minutes or more... see... you love air too!!! |
The bad

AIR INFILTRATION
Too much air making its way into a house or building is not such a good thing. |
Air flows between materials, foundations, wall assemblies & ceiling assemblies exchanging conditioned air (heating & cooling you pay for) with outside air. Air also carries with it moisture which can become trapped and if unable to dry or escape can create a host of problems including mold, mildew & rot.
Energy Efficiency in buildings begin with a tight envelope. Insulation is intended to slow air movement between walls, foundations & ceilings. Proper air sealing using blocking, thermal breaks, foam, caulk & sealants to encapsulate insulation and seal all material component seams & penetrations insure that the insulation used achieves it's intended R-value.
The Department of Energy considers a building with 3.5 ACH (Air Changes per Hour) or less a "tight" envelope. The building envelope when constructed with care will maximize insulation R-value, reduce air flow exchange thereby lowering utility costs and permitting materials to stay dry which will improve indoor air quality.
