Rigid foam board, a type of insulation used in walls, roofs, tanks and foundations, is one of the most effective kinds of insulation on the market – thanks to its high R-value. This board consists of materials which are created during several different synthesizing processes. When large areas are in need of insulation, builders to turn to foam to seal the deal, because using other types of foam insulation can be rather time consuming. Instead of using spray insulation to work on large areas, the board can be a quick substitute.

Foam insulation, in rigid board form is available in many variations, and the type used depends upon its chemical composition and the intended use of the insulation. Most notably, molded expanded polystyrene foam board, polysiso or polyisocyanurate foam and polystyrene foam board are used in construction situations. Also known as bead board, molded foam is diced into boards through the use of a closed cell expanded mass of pentane, which contains beads hence the nickname. The bead board is generally found in use in roofs, and is appreciated for its dense nature, which makes it suitable for use when high pressure resistance is called for.

Foam boards made from polyurethane are generally utilized in situations which require high compressibility and strength. This interesting combination of qualities makes for good use in those climates in which the temperature varies quite a bit. Another kind of foam insulation with the same kinds of qualities is Polyiso, which is closed cell foam capable of high thermal resistance. The latter foam requires R-value stabilization, because it will eventually reduce because of loss of the low conductivity of gas or thermal drift.

Foam comprised of Polyurethane offers homeowners a better deal with maximum R-value, and it is much thicker than polysio foam boards. Like polyiso, however, these boards will eventually suffer losses – time wears them away, and this is unavoidable. This problem can be remedied with a little work; the boards can be repaired with reflecting foils and a little metal or plaster bonding. Polyurethane insulation also comes in the liquid spray form which is best used in small spaces; the convenience of working with boards in large buildings is unbeatable. Because of this convenience and the overall simplicity of working with foam boards, this insulation is very popular indeed. Unlike sheets, which require stapling at installation, foam boards can be easily installed with nails or a special kind of glue. These boards can be installed by anyone even the novice homeowner, and doing so will greatly reduce any potential cost of labor.

A word on deterioration: these boards should be kept out of the sun, which will damage them and reduce their quality. Homeowners should also work to keep them away from excess moisture, which will reduce their effectiveness and may attract mold. To be sure that dangerous mold does not develop; moisture diffusion retarders should be installed along with the insulation. These will also put off any number of other issues caused by excess moisture.
