Homemade Solar Cell

When choosing insulation you will find 4 different kinds. Your choice depends on the area to be insulated, amount needed and cost. I will cover these points so you will know what type to use.

Spray foam is one type to consider when choosing insulation. The insulation comes in easy to use bottles. It’s sprayed into the area to be insulated. It expands as its sprayed filling all the cracks, giving a better coverage. The initial cost is more, but unlike the others you do not need to winterize later. You will find it in insulated attics and finished walls. It’s the best to use in tight enclosed places.

The next to consider when choosing insulation is Spray on foam. This type of insulation is sprayed inside of finished walls and often found in Insulated attics. As it dries it expands to fill the entire area. This insulation has the highest initial cost. Once you consider you do not need to winterize or tear out material the money is about the same.

The third to consider when choosing insulation is foam board. It’s made from fiberglass, polystyrene or polyurethane. This insulation is used in edges of concrete blocks, borders, insulated attics and basement walls. The R factor is a little higher than the other it’s R4-R8 per square inch.

The last one is the batt and blanket. It is made from processed fiberglass or rock wool, It comes in 8 ft’ sheets or rolls. This type of insulation is the cheapest but caution is needed when installing otherwise you may not get desired results. You can find this in insulated attics, unfinished walls and floors.

One thing to consider when choosing insulation is flame resistant’s Fiberglass insulation, spray on foam, batt and blanket are flame resist. Cellulose and foam boards are not. In fact foam boards require flame resistant covering like panel or dry wall.

The entire group I mentioned is ecological friendly. Fiberglass and cellulose is made from recycled material. Foam board decomposes in moisture, and Spray on foam doesn’t contain harsh chemicals. So which ever you decide when choosing insulation you will help the environment.

The four groups batt and blanket, loose fill, Spray on foam and foam board. Each one insulates, but the loose fill and spray on foam covers the cracks and crevices better. Cellulose is a type of loose foam but it is not flame resistant. Foam board is also not flame resistant and requires covering. All are ecological friendly. Most can be found in insulated attics, walls and ceilings.
