How To Install Foam Board Insulation On Interior Walls


One of the best methods to insulate an interior wall is by using foam board insulation. It is a good idea to use this in any room in your home, since it is relatively easy to install and maintain. This type of insulation is available in a wide variety of different textures, types, and sizes to meet any design requirements that you may have.

Many homeowners are surprised at how much additional warmth is actually generated by this type of insulation when it is properly installed. A foam board insulation panel is created by spreading fiberglass or aluminum sheeting over the exterior surface of the wall.

Then it is bonded onto the fiberglass by compressing the material together. The finished product is an interior wall that has a vapor barrier between it and the interior surface on which it is installed. Some types of the material will have an extra layer of glue added at the top to further seal it into the wall.

This is the top coating. The thickness of the spray coating is typically between four and five millimeters. There are many benefits to using foam board insulation on interior walls. One of the best reasons is because it can help reduce energy costs.

Since it is not connected to HVAC equipment, it provides a very comfortable environment inside the home when there is a temperature differential between the interior wall and the exterior. This also helps to prevent sound from penetrating through interior walls.

Because it is connected to the exterior, the warmer air is pulled out of the interior and the cooler air is pulled into the wall. Foam board insulation is also highly effective in reducing the temperature extremes inside the home. This is because it is a fairly rigid material. It is also fire resistant and nontoxic.

It will not expand nor contract when the temperature changes. This can help keep the home much cooler during the summer and much warmer during the winter. One of the reasons that people decide to use it for interior walls is because it is moisture resistant.

This will help to make it much more fire resistant. The material will not catch on fire quickly. If the material gets wet, however, it can take on a “greenish” color and develop a film if left in place. This is why it is important to carefully read the instructions that come with this product before installation.

How to install foam board insulation on interior walls is done in much the same way that it is done for any other wall. First, the wall surface must be prepared. For areas of the wall that are smooth, certain adhesive can be used. It must be spray-adhesive.

How to install foam board insulation on interior walls is also done by placing the board in the area that has been prepared. The space between the edges of the wall and the board should be sealed to prevent moisture from seeping through.

When installing, it is important to leave enough space between the board edges and the wall so that insulation can be layered and built up. When properly done, it will produce an even coverage around the interior wall and provide added warmth.

When considering how to install foam board insulation on interior walls, it is a good idea to learn what kind of boards are available. There are several different types that are available for insulation. They all have different densities and levels of thermal resistance. Make sure to choose the one that will be best for your needs.
