How HD Spray Foam Insulation WorksHow HD Spray Foam Insulation Works
HD Spray Foam insulation works by filling in space and forming a tight seal that keeps air from leaking into or out of your home. It is more effective than traditional insulation in keeping your house warm and cool year-round and can save you thousands of dollars throughout a lifetime with its ability to reduce energy bills.
There are two different types of spray foam insulation – open and closed cell. Each type has its pros and cons that make it a more or less suitable option for your needs.
Understanding Spray Foam Insulation: How It Works and Why It’s Effective
Open-cell spray foam has tiny pockets that are not sealed off and it typically uses water or carbon dioxide as the blowing agent, making it more environmentally friendly than its closed-cell counterparts. This type of insulation is great for walls, attics, and roofs and creates a barrier against air movement and sound. It is more likely to absorb moisture or vapor, which can require the addition of a vapor barrier in some applications.
Closed-cell spray foam has larger cells that are tightly pressed together and is denser than open-cell foam. It is more dependable than open-cell foam and offers protection against air, moisture, and vapor. This is the most durable type of spray foam insulation and is ideal for use in metal buildings.
Both types of spray foam insulation should be installed by a professional technician who is licensed and insured. Spray foam insulation can off-gas volatile organic compounds, and it is necessary to wear protective clothing and breathing apparatuses during the application process. It is also recommended that home occupants vacate the area during the spraying and curing process, which can last up to 24 hours.
