Smart wall insulation3/23/2023 It’s better to insulate over the surface of the concrete either on the exterior or on the interior part of the concrete walls. However, this method isn’t very efficient as the heat dissipates through the solid parts of the concrete wall through mortar joint and web blocks. The concrete foundation of your basement also has an R-value which can be increased if the cores of the concrete are filled with insulation. High performance fiberglass blankets have R-values between R3.7 – R4.3 per inch of thickness. Fiberglass insulation has a thermal resistance or R-values between R2.9 – R3.8 per inch of thickness. Certain batts have flame resistant facing for parts that will be left exposed. Blanket insulation usually come with a facing that acts as vapor or air barriers. Rolls can be hand cut or trimmed according to your basement wall specification. Other types of materials also include mineral wool, plastic fibers and natural fibers. The material consists of flexible fibers like fiberglass. The most common and widely available type of insulation for basement walls is blanket insulation. There are many types of insulation available out there depending on personal preference as well as climate. It’s better to consult your contractor first before picking any. The type of house, the condition of its foundation and the climate plays a big role in determining which insulation is best for you. Interior wall insulation is less expensive, almost any insulation can be used and reduces the threat of invasive insects. However, for many homes that are already built, interior insulation for basement walls are more practical. Insulating the exterior of the basement walls for new constructions will reduce heat loss through the foundation, provide some protection from moisture, protect the damp-proof coating, make the foundation part of the thermal mass of the conditioned space, reducing temperature swings, reduce condensation on the interior part of the basement walls and conserve room area compared to installing insulation on the interior. When your basement is still unfinished it might be a good idea to add a medium size exhaust fan which will help a lot with air circulation. Also it is a good idea to waterproof seal the concrete or brick walls. Make sure any leaks are sealed off before adding insulation into your basement walls to prevent loss of heat. The R-value is the maximum thermal performance of the insulation when properly installed. When deciding on the best type of insulation, you’ll have to take into account the R-value you’ll need for the basement walls you want to insulate. Insulation to the basement wall is done at both sides of newer homes and only on the interior of older houses. It provides a solution to problems like cold air leaking in, mold and fungal growth and saves up to 30% of your energy cost. However, basement wall insulation is a must in any home. However, basements can be one of the most challenging places to work on, partly because of its location. The basement is a standard feature in most American homes.
