A healthy and comfortable home relies on proper insulation. When insulation does its job, it keeps warm air from escaping and cold air from entering during the winter and the opposite in summertime. When there is insufficient insulation or gaps in the insulation, you will have higher than necessary energy bills, poor soundproofing, and potentially water damage that can lead to mold and mildew. Effective insulation can help reduce wear and tear on your heating and cooling systems and even protect your roof during the winter. M&M Insulation in the Twin Cities area has an insulation solution for any problem, renovation or new build.


When warm air escapes through a gap in your insulation, it encounters a cold surface. This can be an exterior wall or somewhere inside the attic. When the warm air meets the colder surface, it creates condensation. The condensation will drip back down into your attic, wetting the insulation and wood, creating a breeding ground for mold and mildew. The same can happen behind your walls if the insulation or vapor barrier has gaps.

One sure sign your attic insulation is inadequate is melting snow during the cold winter months. As the hot air escapes from your home, the attic warms the roof to above the freezing mark. As a result, the snow melts from underneath and then refreezes when it meets the cold eves. At first, you may only notice small icicles, but the ridge of ice will back up onto your roof over time. This can jeopardize the roof’s structural integrity if the ice gets under the shingles and allows water to infiltrate the attic.

Other signs of insulation problems include cold drafts, hard-to-heat rooms, baseboards staining, chronic window condensation, musty smells, mildew, and mold.

The U.S. Department of Energy estimates that up to 40% of the cost of heating and cooling is wasted through air leaks. M&M’s spray foam insulation provides an extremely high R-value per inch, meaning you can get great insulation even with 2 x 4 walls. It is a thermal envelope with no gaps, so there is nowhere for the air to escape or enter. It improves comfort by maintaining constant temperatures.
