5 Different Types of Basement Wall Insulation Explained
Basement wall insulation is not an option, it is a necessity. It is a very efficient solution to various problems, such as mold, high utility bills, and cold air leaking into your home.
You will save at least 30% on your energy bills once the basement has been insulated. Basement insulation is performed by installing the insulation on either the outside or inside of the walls. You can insulate the ceiling, the walls, or both. Most people insulate the ceiling because its area is smaller than the walls.
Blanket Basement Ceiling Insulation
A number of options are available, depending upon the climate and individual preference. The first is blanket basement ceiling insulation. It uses either fiberglass blanket sheets or cotton blankets for insulation. Some of the advantages of this kind of insulation technique are its low cost, wide coverage, and simplicity. A disadvantage with this kind of basement insulation is that it only provides limited thermal transfer.
Loose Fill Ceiling Insulation
Another type of basement insulation is loose fill ceiling insulation. It uses fiberglass, mineral or cellulose wool; both are produced from recycled materials. It is more effective and less expensive; however, costs may increase if there are large gaps and void because they must be totally sealed in order for the insulation to be effective.
Spray Foam Insulation
Spray foam insulation is effective for basements that have been completely built and do not require further renovation work. This type of insulation is very expensive. Some liquid foam insulation products contain types of polyurethane or polyisocyanurate substances, which are sprayed on the basement walls along with the foaming agent.
Concrete Block Insulation
Concrete block insulation is another method. The concrete blocks are fabricated from polyurethane or polystyrene. Their hollows are filled with foam or perlite pellets. Concrete block insulation is a good choice for new constructions, as it requires a lot of work by the mason. Its disadvantage is that it is less effective than the other methods.
Basements can also be insulated with foam boards. They are very helpful in decreasing heat flow. The foam boards are fire-resistant. If they ignite, they emit noxious gases; therefore, they must be covered with a fire barrier whenever they are used.
When a basement ceiling or its walls have been effectively insulated, the advantages can certainly add up. Insulated basements can mean more heat inside the home while cold air is kept outside. It can also mean healthier air quality which is untainted by mold or mildew. Finally, it means a lower heating bill.
