Crawl Space Insulation Duluth, MN
Crawl space insulation in Duluth, MN is often overlooked as the crawl area is not a part of the living area in a house. However, there are many benefits of adding spray foam insulation, some of which are reducing energy costs, preventing cold floors, and keeping pests away.
If your crawl space or rim joist has little to no insulation, all of the chilly air from outside will seep inside your home. You may have freezing pipes in addition to cold flooring in your home, which is very annoying. Added to this, you may have a chilly basement and your HVAC system working overtime to compensate. This is when you need attic insulation or crawl space insulation in Duluth, MN.
Types of Crawl Space Insulation
Fiberglass and spray foam are two of the best crawl space insulation options. It is important that crawl space insulation in Duluth, MN should be such that inside air is prevented in coming into touch with the chilly basement surfaces. Allowing moisture-rich indoor air to circulate can lead to condensation and this will cause the formation of mold and mildew. This mold and mildew can then spread to other areas in the home from the crawl space.
Even though fiberglass insulation is a great DIY option, fiberglass insulation traps allergens and moisture in the crawl area, encouraging mold and mildew growth. If the floor is insulated with fiberglass on the underside, gravity will ultimately force the material to droop. Air flow is a significant cause of cold flooring, unpleasant houses, and expensive energy bills, and fiberglass in the crawl space allows for it.
Which Part of the Crawl Space be Insulated?
You may be wondering which part is installed with crawl space insulation in Duluth, MN. A reputable contractor will suggest putting plastic on the ground and spraying the walls if there is any ducting or mechanicals going through the crawl area.
The crew will then apply a layer of plastic to the floor of the crawl space and walls. The spray foam will then be applied to the walls. This approach isolates the home's foundation and allows the crawl space to maintain the same warmth as the rest of the house.
If your crawl area has no mechanicals or ducts, your insulation contractor may suggest insulating the ceiling. In this case, the crawl space will be air-sealed, isolating it from the rest of the house.
This approach requires the same preparation as spraying the crawl space walls, with the exception that no plastic is needed. The old insulation will be removed once more, and the foam will be sprayed on the underside of your floor by the installation staff. The crawl area will therefore be outside of the building envelope, which means it will not only be cooler than the rest of your house, but it will also prevent cold air from entering your living space.
