Do you want to Installing Foam Board Insulation Basement?
Rigid foam board insulation can come in many different sizes and shapes. Most common is the 4×8 foot sheet that is installed over the foundation wall. You can find this type of foam board insulation in stores like Home Depot or Lowes.
If you are a do- it- yourself homeowner finishing your basement, chances are you might decide to use some form of foam board insulation on the interior side of the wall. There are several types of foam board insulation that you could choose from. Some are designed specifically for basements while others are meant for general purpose applications.
The most common type of foam board insulation is called rigid foam. This type of insulation is usually sold in sheets that measure about four feet wide by eight feet long. These sheets are typically placed directly over the concrete slab. They are attached to the concrete slab using screws or nails.
Another popular type of foam board insulation for basements is fiberglass. Fiberglass is a very strong material that is commonly used to insulate pipes and ductwork. It is also used to insulate crawl spaces and attics.
Fiberglass is much stronger than regular foam board insulation. It is also less expensive than rigid foam board insulation. However, it does require special tools to install.
You can also purchase pre-cut pieces of foam board insulation. These pieces are usually cut into smaller sections that fit inside the space where you want to install it. Pre-cut pieces of foam insulation are easier to handle than large sheets of foam board insulation.

Foam Board Insulation Basement: Continuous Insulation Makes a Perfect Basement Wall
Rigid foam is used as both an interior and exterior sheathing material. In many cases, it is applied directly over concrete block or masonry walls. For example, it is often used as a vapor barrier behind drywall or plasterboard. But it can also be used as the exterior sheathing for a home’s foundation. This type of application requires continuous insulation because the foam must be tight against the structure.
Foam Board Insulation Basement : Preventing Thermal Bridges and Breaks
A thermal break is a way to prevent heat transfer across a barrier. You might think of it like a window screen. When there is no gap between the inside and outside of a building, heat goes directly from one side to the other. This is called a thermal bridge. In some cases, you want to keep heat out. For example, you don’t want warm air coming in during winter months. Or, you could use a thermal break to let cool air in during summer months.
