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

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.

Spray Insulation

Spray Insulation is worth looking into for many reasons, even if it’s not always the ideal solution. Although it is more likely to be the best option for new construction, its features also serve the needs of many existing homeowners who are adding to or trying to improve their homes.

For example, even if the spraying must be done by professionals, and therefore is more costly than other options, the high R-value of spray insulation can make it cost- effective over time, through lower heating bills. In very cold or hot climates this advantage may be well worth the cost.

Spray insulation also carries the advantage of filling uneven areas well. The sprayed foam expands to fill cracks and fit into irregular spaces that would be difficult to work around with other kinds of insulation. The do-it-yourself handyman might be very relieved not to have to work in difficult nooks and crannies, and to just let expansion of the foam do the work.

Another advantage is that spray insulation adheres well to the surface onto which it is sprayed. If a house is being expanded upward, to a second story, then spray insulation under the new floor will be securely in place and offer good insulation for years. It might be a better solution than trying to attach other forms of insulation in such a space.
