Apply close-cell foam insulation through a spraying process that combines two distinct chemicals. Point the nozzle into the desired region, such as into the framework of a building, and spray it until the foam is more or less covering the area. Use a small sprayer tool with close-cell foam insulation to fill in gaps in the region.
One advantage to this type of insulation solution is the additional structural support provided by the foam. Since close-cell foam insulation is considerably denser than the common alternative, open-cell foam, it is often utilized in the construction of ceilings, roofs and walls.
The equipment required to apply close-cell insulation depends on the size of the project. For moderately sized tasks, utilize small aerosol cans to combine the appropriate chemicals. Larger jobs require disposable tanks.
Several different problems can arise when the foam insulation is not properly applied. For example, the foam may not be sufficiently thick if the chemical reaction is not properly balanced. If the individual applying the foam does not carefully check the application site, air may continue to leak out. Another challenge comes from applying the correct amount of foam. To get the most out of this particular type of insulation, it is critical that no excess foam is applied.
