3 Key Things to Consider Before Attic Insulation

Attic insulation has innumerable benefits for homeowners, such as increasing your home’s resale value and melting the snow more quickly after a snowstorm. Research also shows that proper attic insulation can help you save an average of 15 percent of your total heating bill. If you’re looking to insulate your attic soon, here are three key things to consider.

1. Examine Your Attic Carefully

Before you add any attic insulation, evaluate the current condition of the attic. You might need some from a professional builder or architect. Damp or wet insulation and rotted or moldy rafters often indicate moisture problems stemming from a roof leak. That will mean fixing the roof first before insulating the attic. You also want to have a structural engineer inspect the size of the rafters to ensure that it matches the current building code requirements.

2. Seal the Space Properly

Once the inspection is complete, and the roof is in good condition, your next step is to make sure that the attic is air-sealed. Holes, gaps, cracks, and any damage that can allow air transfer between the inside and outside should be eliminated. Your insulating professional can fill the holes and gaps with expanding caulk and foam. Keep in mind that foam air sealing requires proper ventilation. You can get a professional to evaluate your roof and attic ventilation to ensure adequate insulation and temperatures remain consistent with outside temperatures.

3. Choose the Right Insulation Solution

When selecting the right insulation solution, consider the R-value, cost, and available space. The R-value is a rating provided for the insulating material’s thermal resistance per inch of material. That means that a high  R-value provides better insulation than a lower R-value. Different types of insulation take different amounts of space. The cost also varies based on the type of insulation you choose, including the labor required.
