Rigid foam insulation, as seen in its name, is used to insulate entire homes. Why do we say entire homes? This is due to the fact that using rigid foam insulation allows you to attach the insulation to studs. In this way, you will be able to receive continuous coverage of the insulation. You are also able to insulate headers and frames, which includes the doors and walls of the structure.

Using an insulation which excludes frames and studs means potential air leaks are present in the said areas. It also means that you are not acquiring total insulation coverage since 25% of most wall surfaces are made up of headers as well as frames (doors and windows).

Types of Rigid Foam Board Insulation

Rigid Foam Board Insulations are of three types. These are: polyisocyanurate, polystyrene, and polyurethane. Each of these has advantages not present in other types.

Polyisocyanurate—the polyisocyanurate rigid foam insulation type and the polyiso foam boards are best suited for installing attic insulations. This is due to its durability and strength. It can withstand extreme temperatures. When employed with aluminium foil facing, it has a moisture barrier.

Polystyrene—this rigid foam insulation type is best suited for attic insulations and walls. It utilizes pressure and deep heat for shape molding. Even though it is the most costly among the other types, it is the strongest and most durable of all.

Bead Board—this is the last type of insulation. It creates a better insulated region due to the capability of the bead to expand. This expansion allows the bead board to fit the desired area.The spacing of the beads allows for the absorption of moisture. This rigid foam insulation type is seen in the products we use daily.

Things to Consider When Using a Rigid Foam Insulation

You should have a flame retarder. This product requires a lot for its ignition, after which, it will continue to burn steadily. Sometimes, the flame retarder will smolder. When using this product, you should be mindful of the safety regulations. You should utilize materials that are flame resistant. These flame resistant materials include dry walls, panel, as well as gypsum wall boards placed over the insulation.

Attic insulations deteriorate because of the sunlight’s direct heat. Therefore, it should be protected with rubberized paint asphalt, tar, roofing felt, or acrylic silicone. You should also utilize insulations treated with insecticide. This is due to the fact that bugs love to create nests in insulations, especially those in floors and basements. Another way to prevent bugs in the insulation is by place them in the interior or inside part.

Also, keep in mind that these insulations absorb moisture which leads damages of the wood. Absorption of moisture also leads to molds. In order to prevent this from happening, you should utilize a vapour diffusion retarder. This is best suited for attic insulations.

Rigid foam insulation requires a cheap start-up cost. You must make sure that it is properly installed as it can be counter-productive. You must also consider the safety precautions involved in this type of insulation. Before using rigid foam insulation, you should read safety precautions and code regulations for local buildings.
