Foam Board Insulation: Molded, Expanded Polystyrene Foam Board

If you are building a home then a foam board insulation will be needed to insulate the house. Molded expanded polystyrene foam board is one of the many types of foam board that can be used that help on reducing the heat transfer.

R Value of Foam Board

The R value of a foam board is ranged from 4 to 8 R values which corresponds to the thickness of the material. To know the R value of the foam board will help you determine the amount of thickness you need for the part of the home you will be working on.

Beadboards Characteristic

The beadboards or molded expanded polystyrene foam board is a characteristic of this material because of how the beads react. The beads need to be inside a container which needs to be heated which then expands their size to 30 times their original dimension. These beads will have a foam thickness of around R-4 and then will need to be cut into the shape you want.

Physical Information

The molded expanded polystyrene has varying R values based on the type of beads you will want to use. If you need foam insulation for a wall or the roof you will need to find the correct R value that will be thick enough.
