In years past, most people just stuffed layers of fiberglass batt insulation into their attics without even thinking of the alternatives. Today, there are a number of insulation choices, from standard fiberglass, to recycled cotton, to perhaps the most high-tech of them all: spray foam. Some homeowners are intimidated by the prospect of spray foam insulation, since it needs to be sprayed on with special equipment and by a knowledgeable contractor. However, if you have the chance to insulate your attic with spray foam, you definitely should. Here's why:
Spray foam does not absorb moisture.
Even the newest of roofs can develop leaks, and when you have most any type of insulation other than spray foam, the water gets absorbed into the insulation. This causes your attic to stay moist for a long time, which promotes molding and may cause you to have to replace the insulation.
Spray foam insulation, however, repels water. The water just rolls right off its surface. This makes it easier to dry out your attic, so you don't get mold. It also means that you don't have to pay for insulation replacement on top of roof repairs.
Spray foam seals little holes and cracks.
Heat leaves your attic in two ways. It is transferred directly through the building materials, and it also leaves in the form of warm air blowing through any cracks and crevices. Fiberglass and cotton insulation take care of the direct transfer issue, but they don't block air flow through the little cracks and holes. Spray foam automatically plugs these little holes, including those around pipes and electrical wiring, as it is applied. This will lead to a more comfortable home and a reduction in your heating/air conditioning bills.
Spray foam won't need to be replaced.
Dragging old insulation out and replacing it with new insulation is not a lot of fun. If you choose fiberglass or cotton insulation, you'll need to do this at some point, since these types of insulation eventually lose their ability to insulate as they absorb moisture and become compacted. With spray foam, on the other hand, you never have to worry about replacing your insulation. Spray foam should last just about forever – or at least for the life of your home. While it may cost a bit more up front, it will save you money in the long run since you never have to replace it.
