When installed correctly by a certified installer, spray foam insulation can create an impenetrable airtight seal. This helps reduce the number of drafts that occur, which is often a source of energy loss and high utility costs for homeowners. It can also increase a home’s R-Value and help prevent mold growth in uninsulated attics. URL www.cashhouseclosers.com/hickory/

The most common spaces that are insulated with this product include attics, crawl space walls and rim joists. It can also be used in new construction homes, pole barns and commercial buildings. Spray foam can be sprayed directly onto existing drywall or into open cavities, such as those around electrical outlets or light fixtures. It is also used to seal ductwork and reduce leakage, which can be a major cause of heating and cooling expenses for homeowners.

Spray foam can be used in both closed and open-cell varieties. The difference between the two is that open cell foam remains soft once it has set, while closed cell foam becomes rigid once it has set and provides a higher R-Value per inch. Closed-cell spray foam is more suited for cold climates like Vermont’s, as it resists moisture and condensation better than open-cell insulation.

It is important to work with a qualified contractor when using spray foam insulation, as improper installation can lead to significant moisture damage and rotted framing. A spray foam specialist should be able to assess the condition of a home’s current insulation and recommend the right product for the job. They should also be able to provide a duct blast test and help homeowners identify and seal air leaks, which can be a major cause of energy consumption and comfort problems in the home.
