Deal With All Moisture Issues Before Insulating Walls
Insulating your basement walls is an important step in making sure you have a comfortable and energy-efficient home. There are many different approaches to insulating basement walls, each of which offers different advantages and disadvantages. This article will provide an overview of what is involved in insulating basement walls and help you make the best decision for your home.
Before you begin insulating your basement walls, it is important to take care of any existing moisture problems. Make sure that there is no standing water or standing condensation on the walls. Any moisture that is not addressed could cause damage to the insulation and reduce its effectiveness in keeping you warm. Additionally, check for any cracks or gaps in the wall, and check the plumbing pipes to ensure there aren’t any leaks. If there are any leaks, be sure to fix them before continuing.
Rigid Foam Insulation
Rigid foam insulation boards are one of the most common types of insulation used in basements. The boards come in different thicknesses and can be cut to fit the walls. They are also easy to install as long as the walls are clean and free of dust and debris. Rigid foam insulation boards are very resistant to moisture and provide excellent insulation, but they can be expensive and difficult to remove if you ever need to access the walls.

Rigid foam boards can be attached to the basement walls using adhesive, screws, nails, or clips. It is important to make sure all the edges of the boards are sealed properly to prevent cold air from entering the basement. An adhesive can help seal any small gaps between the boards, but it may not be enough to completely fill larger gaps between the boards and the walls.
All Gaps in the Insulation Should Be Sealed
Once the insulation is installed, all gaps, even small ones, must be filled. Most often, a spray or caulk will be used to fill these gaps. You can buy either a latex or acrylic sealant to do the job. Make sure the gap is completely dry before you seal it, otherwise, the sealant will not adhere properly. To ensure that the sealant adheres properly, use painter’s tape to hold it in place until it dries.
Thermal Barrier Requirement
In many parts of the country, a thermal barrier is required when installing a rigid foam board in a basement. A thermal barrier is typically a layer of drywall or metal sheeting that helps prevent heat loss from the insulation. While thermal barriers are not always necessary, it is important to check with your local code enforcement office to determine whether your area requires one. Installing a thermal barrier is relatively easy and can help ensure that your basement walls are properly insulated.
Insulating your basement walls is an important step in creating a comfortable and energy-efficient home. Make sure to address any existing moisture issues before beginning, and choose an insulation material that is right for you. Once the walls are insulated, be sure to seal all openings and consider installing a thermal barrier to ensure your insulation works as efficiently as possible.
