There are four types of insulation Expanding foam insulation, batt and blanket, loose fill and rigid board. I will discuss all four so you will have better knowledge 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

Next we will consider rigid board when we are choosing insulation. It’s made from fiberglass, polyurethane or polystyrene. It’s used in basement walls cathedral ceilings, flat roofs and building perimeters. Rigid board is not moisture or flame resistant. Bugs often burrow in this insulation. This product required to be covered by fire resistant paneling or dry wall. I wouldn’t consider rigid board when choosing insulation.

The third is loose fill insulation. Like expanding foam insulation. This insulation is blown into unfinished walls attic and ceilings to make a blanket effect. It is made from cellulose or fiberglass. Loose fill is treated for moisture and fire resistance.

The last is Expanding foam insulation. When choosing insulation I would have to say this is my favorite. Like loose fill it too is blown into walls. As it dries it expands to fit every crack. Once dried excess is cut away and a thermal barrier is applied.

Expanding foam insulation has many benefits. It reduces wind washing, sound and condensation. It improves air leakage, air quality and lowers heating and cooling bills. It protects against floods and doesn’t deteriorate in time. It can be used in extreme temperatures effectively. You don’t need to winterize further. It can be applied over the old insulation material.

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.
