Smart Sealed Insulation Choices
When most people think of insulation, they think fiberglass. Unfortunately, conventional fiberglass insulation, regardless of the R-value, leaves gaps and seams around a house’s framing material, allowing air to flow both in and out. The fact that it’s air permeable means fiberglass insulation permits energy loss, allows for the transfer of airborne pollutants and pollens into your home, and allows moisture into your home that can lead to mold and mildew. New forms of insulation such as spray foam and blown-in cellulos are more effective at insulating your home. Both types possess a much higher density than fiberglass, which means they do a better job of inhibiting air movement. Foam and cellulose provide superior seals, limiting airflow not only through the insulating material itself, but also in hard-to-insulate areas such as gaps around electrical boxes, wiring and plumbing.
