If you are looking at insulation for your home, there are more choices than blown cellulose and pink fiberglass. Expanding spray foam insulation is increasingly popular due to its many benefits.
Expanding spray foam insulation is made of polyurethane or acrylic latex. The foam has been used in refrigerators and water heaters for many years.
Liquid polyurethane is pressurized and released through spray nozzles. When the spray lands on surfaces it expands and foams up, then hardens to a aerated material. Traditional insulation such as cellulose wool or spun fiberglass leave gaps and voids when applied as ceiling and wall insulation. Expanding spray foam insulation fills out to all cracks and into seams even if they are hidden from view. The sealing ability can practically eliminate air flow and energy transfer.
To prevent heat escaping through the attic and the walls of a home fiberglass batts have been a traditional insulation. New advances in insulation offer a better solution that is easy to install and on the budget.
The contemporary best practice is expanding spray foam insulation installation. Foam fills the cavities in between the framing studs of the walls and attic. Spray-on foam expands to fills in air gaps, unlike standard fiberglass insulation, which lets air pass through and around it. Even as a house expands and contracts the foam insulation expands and compresses with it. This prevents warm air from escaping through cracks and spaces.
Expanding foam insulation is a method of applying a liquid resin that reacts with air to expand into its surroundings. The resin can be injected into small or large voids to fill the space with a solid foam. The resulting foam can seal gaps and cracks to prevent air from entering into your home. It can be sprayed onto larger areas to provide a thick layer of insulation for resistance to heat transfer.
There are many benefits to this form of insulation over traditional materials. These benefits include ease of installation and durability.
