What are the Benefits of Expanding Foam Insulation?

By Edward Nave

There are four insulation types' to consider when choosing insulation they are; batt and blanket, rigid board, loose fill and Expanding foam insulation. I will talk about each individually so you will have a better understanding when choosing insulation.

How is Expanding foam insulation applied? Contractors use special equipment to shoot either polyurethane or modified urethane liquid into the area. While drying it expands to fill every inch, once it's dry, the excess is scraped off and a thermal barrier is applied

The second cheapest to consider when choosing insulation is the rigid foam board. It's made from polystyrene, polyurethane or fiberglass. It's used in basement walls, high ceilings, flat roofs and perimeters. It's not flame resistant. So it required covering with fire proof paneling or dry wall. Since bugs nest in this insulation. It's suggested to use an insecticide treated material for basements.

When choosing insulation there are three other types to consider; loose fill, batt and blanket and rigid foam board. I will talk about each briefly.

The last is Expanding Foam insulation. This insulation is my favorite when choosing insulation. It is made from modified urethane or polyurethane. The product is blown into the walls, expanding while it dries to fit the entire area. Once dry, excess is cut off and a thermal barrier is applied according to regulations.

When choosing insulation you should think about Batt and blanket. It's made from fiberglass and rock wool. It's installed between studs 16-24" apart. It's the cheapest, but proper installation is needed. After installing the house needs winterized further.

The last to consider when choosing insulation is rigid board. This is made of fiberglass polystyrene or polyurethane. It's installed in flat roof reproofing, basement walls cathedral ceilings and perimeter insulation. Unlike expanding foam insulation it's not flame resistant and should be covered with either fire resistant paneling or dry wall. Bugs often make nests in this insulation so insecticide treated material is needed when insulating basement walls. Because of these problems I would not pick rigid board when choosing insulation.

There are 4 types of insulation all having jobs they are better suited for than others. Out of the bunch I would pick Expanding foam insulation when choosing insulation. It covers the area better, improves air quality and reduces bills. Expanding foam don't weaken over time or require further maintenance and reduces noise.
