About foam insulation
Foam insulation is considered one of the best ways to prevent heat transfer. They are great for home insulation and can reduce energy costs. Before you start insulating your house, you need to know a few things about foam insulation.
Application. To apply the foam, you will need some special equipment. This equipment is usually operated by a professional, although it is not that complicated. With this machines, you can fill cavities, insulated and fill spaces.
Properties. Foam insulation will not settle, shrink or sag. It restrains its properties through out its life.
Energy. Usually the R-factor is higher on foam insulation then on other insulators, like fiberglass. This means less money spent on energy.
Costs. Foam insulation is quite expensive, but in the end, after comparing the additional costs, you will see that this is a very competitive price among insulation materials. With foam insulation you will not need any caulking or vapor barriers.
Product types. There are two main types of foam insulation, closer cell of polyurethane, with a higher R-value, and open cell or isocyanurate. They are both applied in liquid form and they will expand because of a foaming agent.
