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.

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.

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.

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.

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.

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.
