Foam board insulation products are commonly used in buildings. Foam board insulation has a relatively high R-value compared to other types of insulation. Many variables affect the final R-value of foam board insulation .The initial density of the foam board are blowing gas used and how the panels are handled and the type of facing used, and the conditions under which the panels are installed.

Several methods of installing: Foam board insulation

There are several methods of installing foam boards insulation. You can spray it as a chemical mixture from a small aerosol container, or you can apply it in bulk from a pressure sprayer. As the chemical mixture cures it also fills and seals odd-shaped spaces and wall stud cavities. You can also apply the foam as a liquid that flows over obstructions before it expands. One can pour solidified plastic foam as loose beads into concrete blocks or install it as rigid panels that can be cut to size.

Foam board insulation has also an alternative if there is insufficient space to install non-foam products, or when an equal R-value of non-foam insulation would require structural changes to install it. Although many insulation products, such as fiberglass and cellulose, cost less per their given thickness. Foam board insulation also controls air infiltration more effectively than most other forms of insulation.

Common Applications of Foam board Insulation

It is required to spray foam and foam boards insulate roofs, curtain walls, foundations, entry and overhead garage doors, pipes and tanks, and climate-controlled storage units. They also serve as sheathing and insulation on the inside surface of a basement or crawl space wall, beneath a basement slab and slab-on-grade floor. Exterior applications are dependent on inside or outside foundations, crawlspaces, and slab-on-grade foundation walls. There are several ways to incorporate foam board insulation in concrete or masonry walls: pouring loose foam beads into masonry block

Foam board Insulation: Potential Moisture Problems

In cold weather, warm inside air containing water vapor which can pass through the wallboard and wall insulation and condense on the cold exterior wall surface. If this condensation cannot escape, moisture-related problems occur.
