Everybody Is Using Expanding Foam Insulation?

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.

When choosing insulation Batt and blanket should be considered. It’s is made from fiberglass and rock wool. It’s used in walls and ceilings of unfinished buildings. Contractors usually install between studs 16-24″ apart. It’s the cheapest, but without proper installation it will have a minimal effect. After installing you will need to vapor seal, house wrap or caulk.

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.

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.

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 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.

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.

When choosing insulation you have to consider the good and bad qualities of each type of insulation. Although batt and blanket is the cheapest initially, proper insulation is required. Rigid foam boards is also inexpensive but unless treated can obtain moisture and harbor bugs. Both require further weatherization. Expanding foam insulation and loose fill both effectively cover the area without bugs, or retaining moisture and without further weatherization.
