Where to Insulate a Home
Homeowners should be aware that there are more places to install insulation in their home than just the exterior walls. Insulation contractors in Maine should advise their customers on all of these places that should be insulated. They should also test for R-value (or the thermal resistance rating) at these areas in the home when performing an inspection. By insulating these key areas in a home, your home will be both more comfortable and more energy efficient.
Many homes, particularly older home have an attic which is unfurnished. This is a constant drain on your HVAC systems and should be insulated as soon as possible. Before insulating the attic, be sure that ay air leaks or necessary roof repairs have been made. The knee walls—vertical walls with attic space behind them—should be air sealed an insulated. If building a new home, be sure that there is room in the attic joists to add insulation.
Air Duct Insulation
Many home have air ducts for their heating and cooling systems which are uni-nsulated. This is especially true in homes that were originally built without central heat or air. Condensation can build in these areas, so it is especially important that proper steps be taken not only in insulate ducts in the home, but also that moisture is not going to be problematic for the type of insulation you choose.
Exterior Wall Insulation
This is the most common area people know needs insulated. One of the easiest, cleanest, fastest, and most effective ways to insulate exterior walls is through the use of spray foam insulation. Minimal mess and damage is done to the home as small holes are drilled into the walls and then spray foam insulation injected in through those holes. Those can then quickly and easily be patched over.
Foundation and Basement Insulation
A lot of home owners are unaware that they can insulate their basement without having to have a finished basement. Properly insulated foundation and basement areas can save a lot of money when it comes to heating the home. As the basement is connected to the rest of the home, it is wiser to insulate the basement than to try and insulate the basement ceiling and block it off from the floors above.
RetroFoam insulation can be added to an already completed foundation, filling cracks in concrete and mortar. It is also rated for safety as a flame retardant material, which means it will pass code inspections of the home. As spray foam doesn’t deteriorate like cellulose or fiberglass insulation when it gets wet, it is better suited as a foundation insulation product than many other choices on the market.
If you are insulating a new home in Maine that uses a natural gas furnace, or an existing home with an electric furnace, or a new home with a heat pump, etc.—these numbers are pretty much across the board and they are good to know when speaking with an insulation installer in Maine–it is recommended that your attic have an R-Value of 29, floors an R-Value of 30, wall cavity at least 15, and 15.6 for insulation of a concrete wall. Basement and foundation R-Values should be 12 for the slab edge and basement wall exterior while 25 is the recommended R-value for basement wall interior and crawl space areas.
