Attic roof insulation – An additional insulation of the roof and the wind can provide numerous benefits for housing and homeowners. One of the major reasons that the additional insulation roof is to reduce energy costs. Additional insulation of the roof is the single best thing you can do to reduce the heating costs of a house. It is both cheap and efficient. Approximately 15 – 18% of the heat from a normal insulated house disappears straight up at the ceiling. The number can easily be reduced significantly by adding on an extra layer of insulation in the attic. It is an investment that pays off quickly and directly felt in the wallet.
It is possible to make large energy savings by extra attic roof insulation. Heat rises notoriously upward, and by stopping the air flow through the ceiling and up the ridge, also prevented the heat from escaping from the housing in the house. Many older homes have poor roof insulation. It is not uncommon with an insulation thickness of only 100-150 millimeters. It applies to the mineral wool. When it comes to the classic sawdust layer usually be about 150-250 mm thick.

Additional attic roof insulation, one of the difficulties that need to be looked up to as a wind re insulated is that there could be moisture in the attic. That’s because the wind gets colder than before, when warm air pushed up through the insulation. Moisture can in turn lead to mold and rot. No matter with which materials you isolate with, the wind kept well ventilated. We also need a vapor barrier or alternatively a vapor barrier on the inside of the attic floor.
