Expanding Spray Foam Insulation Installation

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 Spray Foam Insulation

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.

Fire Resistant Foam Insulation

Fire resistant foam insulation contains fire retardant, and some are specifically formulated for fire resistant use.  If you need a fire resistant foam for insulation, be sure to choose one specifically marketed as such.  These products possess a higher degree of fire resistance than standard foam insulation.

Fire Resistant Applications include :
– fire resistant installation of window and door frames
– fire and smoke resistant sealing of connections between walls, ceilings and floors
– sealing of all openings in roof constructions
– sealing of cable and pipe penetrations in walls
– improving thermal insulation in heating and cooling systems
