How To Insulate Concrete Walls With Foam Board Insulation

When it comes to insulating concrete walls, foam board insulation is an excellent choice. It is relatively inexpensive, easy to install, and can provide excellent insulation value. However, there are a few essential aspects to consider when insulating concrete walls with foam board insulation.

Preparing the Wall Surface

Before installing foam board insulation, it is important to prepare the wall surface. This involves cleaning the surface of any dirt or debris, and then applying a layer of primer or adhesive to help the insulation adhere to the wall.

Choosing the Right Foam Board Insulation

There are a variety of different types of foam board insulation available, so it is important to choose the right one for your needs. The most common type of foam board insulation is polystyrene, which is made from recycled plastic. Polystyrene is a good choice for insulating concrete walls because it is lightweight and easy to install. However, it is not as fire-resistant as other types of foam board insulation.

Installing the Foam Board Insulation

Once you have chosen the right foam board insulation, you can begin installing it on the wall. Start by applying a layer of adhesive to the back of the foam board insulation. Then, press the foam board insulation into place on the wall. Be sure to stagger the joints between the foam board insulation panels to prevent air leaks.

Finishing the Insulation

Once the foam board insulation has been installed, you can finish the insulation by applying a layer of drywall or plaster over the foam board insulation. This will help to protect the foam board insulation from damage and will also improve the appearance of the wall.

Insulating concrete walls with foam board insulation is a relatively simple process, but it is important to follow the steps outlined above to ensure that the insulation is installed properly. By following these steps, you can improve the energy efficiency of your home and make it more comfortable year-round.
