A fairly easy project for homeowners to take on themselves is installing insulation in the attic, and the benefits are noticeable immediately.
First step to insulating your attic is to seal up joints and cracks with insulation foam; doing this can save you up to 20% a year on heating and cooling costs. Use the Energy Star website to choose the right R-value. R-value is the ability of the insulation to slow the transfer of heat. The higher the R-value, the better the material’s ability to resist the flow of heat through it.
If your attic has some insulation already, install insulation that does not have a moisture barrier. Start by cutting insulation and installing it in areas that have small access. After that, you can continue in open areas by rolling out the insulation. Lay new insulation perpendicular to any existing insulation, right over the rafters. Be sure to lay insulation edges tightly next to each other to maximize the efficiency. Even if you’re not comfortable taking on this project yourself, there are many qualified contractors who can help you get the work done.
