Is Insulating Basement Walls Worth It?

Insulating any part of your home is often one of the best investments a homeowner can make. The basement is an area where a lot of cold air resides, but adding insulation to the basement can stop any cold leaks, increase energy efficiency, and reduce energy bills. Sealing and insulating basement walls helps reduce humidity and heat loss, while preventing moisture from leaking into the house. To prevent condensation from forming in the basement, it is recommended to use sealing tape, putty, or spray foam insulation to fill any crack, gap, or narrow opening that is too small to be insulated with rigid foam panels.

The structural elements of underground walls are cold (concrete is in direct contact with the ground), especially when they are insulated inside. In this case, the wall is 13 feet high and 30% thicker to accommodate the external load on the wall. TBF EverLast wall panels, a hard foam panel and concrete slabs, have a 50-year warranty against moisture, mold and basement floods. This begs the question: why insulate the lower walls of the basement instead of taking advantage of the heat from the floor? After a few years have passed, I noticed that my heating bills have dropped by about 27% by leaving the heating turned off in the lower basement and allowing them to rise a few degrees in the main house.

There are two main methods for insulating basement walls. The first method uses roll-up strips to fix the insulation to the wall, while the second method involves framing the wall over the insulation. Although energy savings from sublosa insulation are not as significant as those from insulating basement walls, such insulation offers a significant improvement in terms of comfort and resistance to damage caused by moisture (even against condensation in summer). Whether you're adding new insulation or improving existing insulation, insulating interior walls of the basement can help you save on heating costs over time.

The air that enters a basement brings with it basement temperatures and, because this area of the house is at least partially underground, it's generally much colder in the basement than in other parts of the house. The lower area of my basement never dropped below 17 degrees Celsius even though I never restored heating there in 4 years. The government recommends focusing on insulating basement walls over ceilings when looking to improve energy efficiency. This is especially true since the effect on energy consumption is approximately the same regardless of whether insulation is installed inside or outside.

When a house is properly insulated, you don't have to worry about wearing extra socks in winter or about rapid temperature drops. Whether added to walls, ceiling or floor, basement insulation helps make the space more comfortable and energy efficient.
