Why Should I Choose Expanding Foam Insulation?

By Edward Nave

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.

The first we will consider when choosing insulation is loose fill. This insulation is made from either cellulose or fiberglass. It makes a blanket effect when it is blown into the walls. Contractors use it attics and walls in unfinished buildings. This type is treated for fire resistance and moisture.

When choosing insulation, you should consider the numerous of benefits of expanding foam insulation. It makes a good air sealer, improving air quality, lowers heating and air-conditions cost. This eliminates wind washing, caulking, house wrap or vapor seal. It can be used in high or low temp. It reduces noise, helps against flooding and controls condensation. It doesn't shrink, is not biodegradable and makes structures sounder. You can apply this over old material.

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. 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.

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. 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. - 29956
