Rigid foam boards, sprays, and injectables are some foam insulation products that can be used to improve the comfort of your home. The addition of foam insulation will reduce drafts. This type of product can be installed in any empty cavities that comprise each floor in your home.

Foam Boards

Polyurethane and polystyrene are two plastic polymers that foam insulation is made of. Foam boards are suited for filling large spaces, such as surface materials that comprise ceilings or areas behind walls. Foam boards lay flat and may be varying widths and thicknesses. A contractor will order products that adequately fit the gaps that they are designed to fill. If new drywall will be installed within a home or a garage, the use of foam boards may be preferred.

Because foam boards can be custom-sized, it is relatively easy to fill large gaps quickly and ensure that there are no voids surrounding them. Some foam insulation products contain flashing. The flashing is a material that will be secured along one side of the boards. When the boards are installed properly, the flashing will prevent moisture from penetrating. If foam insulation boards will be installed along exterior walls, the flashing will keep the inside premises dry and prevent moisture accumulation from damaging structural components.

Sprays And Injectables

Sprays and injectables are two foam products that are typically used for small insulation projects or for ones that may consist of adding insulation to confined areas that cannot be reached easily. For instance, a property owner may decide to have foam installation installed, but not want to deal with the disruption associated with taking drywall down and reinstalling it at the conclusion of the foam installation process.

In this type of situation, a general contractor may advise that a spray or an injectable is used. These products will adequately insulate a home or garage, but won't necessitate a lot of prep work. A contractor may be capable of using rigid boards behind existing drywall, but could potentially charge much more money to install this type of insulation.

A complicated insulation job that would necessitate tearing down interior walls could take much longer to complete than an insulation project that uses an expandable foam product. Foam that comes in a canister will expand after it is applied. A contractor may need to remove a minimal amount of structural components before applying the expandable foam.
