Should i insulate my attic roof.
For a correct approach an inner roof lining is required.
After this amount of time insulation begins to peel away from the walls and degrade.
A good rule of thumb is that standard insulation should be inspected to see if it needs to be replaced at least every fifteen years.
The technically correct approach depends on a number of factors.
Home ceilings are usually insulated in order to seal off the extreme temperatures in your attic.
Insulation roofing there are various factors that affect how often a home s attic insulation should be replaced.
Because the simplest and cheapest way to insulate an attic is to add material to the floor.
Whether or not there is an inner roof lining and the total thickness of the roof structure.
Don t forget the roofline if your attic is part of your living space or you live in a home with a cathedral ceiling or other low pitch type.
Warm insulation is installed on the underside of the roof deck at the top of the attic just below the roof decking.
If you d like to finish your attic you will need warm insulation.
Plan to pull up the flooring and layer new insulation on top of the old.
If your attic is often used or perhaps you plan to convert it in the future you will need to insulate the inner surfaces of the roof.
If your attic is usable space but not lived in then you won t need to insulate the roof rafters as long as the ceiling floor that separates the roof from your living area below is insulated.
If you decide to insulate at the roof level then that is a decision to bring the attic into the conditioned space of the house so you re correct the gables would be sealed up and you keep a clear channel for air between the insulation and the roof deck.
