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.
Ease of Installation
The chemical resin can be sprayed in liquid form onto the desired area without measuring, cutting, or fasteners. It adheres to practically everything used in typical house construction such as concrete, masonry, wood, and metal. Application is fast and simple.
Expanding foam insulation lasts longer than previously used materials. It maintains its effectiveness longer with resistance to breakdown, compression, moisture absorption, or attack by critters.
Since it is unaffected by moisture it also is practically impervious to mold even in damp areas. Because it is inorganic it is not attractive to animals and insects for eating, gnawing, or nesting.
The inorganic compounds are non-polluting and benign to the environment. The effectiveness of using expanding foam insulation improves the air quality of your enclosed spaces by preventing infiltration of exterior pollutants from entering.
The biggest benefit of using expanding foam for insulation and sealing is the reduction of energy transfer. Thermal resistance reduces conductivity, and sealing gaps and cracks reduces air convection. Overall energy savings are considerable and make it cost effective to use expanding foam insulation.
