Expanding foam insulation is used for ceilings, walls, attics and basements. It’s also used around window seals, electrical boxes, outlets and other small, enclosed places. Sailors use it for docks and pilots to strengthen airplane wings. What is it, and how is it applied? I will give you details on this and the other 3 insulations types, in hopes to assist you 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.

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.

Loose fill made from fiberglass or cellulose like Expanding foam insulation it’s blown into the walls to make a blanket effect. It is used in unfinished attics and walls.

Expanding foam insulation has many uses from finished walls, ceilings, floors to boat docks to airplanes. Contractors especially like this insulation in tight enclosed places like electrical boxes, outlets, and window seals.

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.
