Insulated Attic Preparation: What To Consider When Choosing Insulation
June 5th, 2009 | 
Author: 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.
Foam board is made from polystyrene, polyurethane or fiberglass. Its uses are; for edges of buildings, concrete block perimeters, insulated attics and basement walls. It has the highest R factor, R4- R8.
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 loose fill. It too is sprayed inside finished walls and insulated attics. This gives better coverage, air leakage protection and better inside air quality. There are two types’ fiberglass and cellulose. Its R factor is 3-4 per square inch.
The third type to consider when choosing insulation is foam board insulation. It is made from fiberglass, polystyrene or polyurethane. It comes in various thicknesses and is used for flat roof reproofing, basement walls cathedral ceilings and perimeter insulation. Its factor is R4-R8.
Flame resistance is important when choosing insulation. The two that are not flame resistant is foam board and the Cellulose loose fill. Cellulose being made from paper can reignite. Foam board is required to be covered with dry wall or flame resistant paneling.
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.
