Attic insulation is of prime importance since attic is the place from where maximum heat loss occurs
. The effectiveness of an insulation material is judged by its R-value, with a higher R-value material resulting in better insulation. You can either use loose fill insulation of batt insulation in your attic. One of the most common mistakes made during the attic insulation process is omitting a vapor barrier. Omitting the vapor barrier will result in water accumulation between the insulating layer and the roof of the attic.
Another area in the house that can let heat escape is the basement. A basement can often have numerous joints and crawlspaces that can result in significant heat loss. While insulating the basement it is important to ensure that any structural damage or moisture leakage is fixed prior to insulating. In case you insulate over these structural damages and leakage points, there is a chance that
Before initiating the insulation process it is important to be clear on the different types. The four most commonly types of insulation are loose fill, rigid board, spray foam and
Batt Insulation. Out of these, batt insulation is the most preferred insulation type since it is the most effective. Batts can be found with aluminum or cardboard facing, or without a facing. A 'without face' bat is generally used to add-on to the existing insulation in the house.
One of the most essential points that you should keep in mind is that a number of insulating material are highly combustible and should never be left exposed. Fiber glass is a non combustible material, while cellulose is highly combustible and should be specially treated with fire retardant chemicals.
