What features do my walls need to keep my home comfortable and protected from the elements?

For the best results, you want to keep the air out of your home and the moisture out of the walls.  This will enable your home to heat or cool efficiently, keeping the home comfortable throughout the changing seasons.

What can I do to control moisture?

You need a system that contains exterior damage, an air barrier, and a vapor barrier.  Hire a pro to install the proper components to block moisture before it impacts your walls negatively.  At Assured Insulation-Decatur, we can help eliminate the moisture problem with proper insulation solutions in your walls.

Why is it necessary for my walls to be airtight?

You don't want moisture to collect inside your walls, causing big problems down the road. Sometimes during construction, the potential for air leaks occurs, allowing moisture to get into the walls.  Air sealing, when combined with insulation, creates an impactful difference in comfort and performance.

Which type of insulation is best?

Walls keep the extreme temperatures out and the climate-controlled temperatures in.  A qualified installer can apply wall insulation to keep your home at a comfortable temperature.  Blown insulation like spray foam or cellulose will provide the best results, as they will have the highest R-value and tightest air seal to provide the maximum amount of comfort and cost savings available.
