Spray foam refers to a chemical product that results from the reaction of two other materials. The two materials reacted to make it are polyol resin and isocyanate. When there two materials react, they expand between 30 and 60 times after being sprayed in a place. Due to the expansion, this material has become a specialty parking material which forms to the shaping of the commodity being packed. It also offers high thermal insulating capability. When one needs to purchase Spray Foam Insulation Long Island NY should be given priority.
The material was invented by Otto Bayer in 1937. Otto Bayer was exploring the main idea he had about creation of dry foam insulators through mixing chemical substances in small amounts when he came across the invention. Polyurethane was used for industrial applications and other extra functions like cushion and shoe making. In the 1940s it began being used as inelastic foam in airplanes and in 1979 it began being used as building insulation.
There are various properties of spray foam insulation that make it a superior insulator in a wide range of applications. The first property relates to its high R-value. The R-value range is 3.4 and R-6.7. Cel structures and densities also come in a wide range. The wide range of R-value makes the material suitable for residential applications. It has the ability to block heat loss through conventional, radiation, and conduction mechanisms of heat transfer.
SPF insulations exist in two major types. The two types are medium-density closed-cell and light-density open-cell SPF. Even though they may vary in composition, they are both thermoset cellular plastics that have millions of cells in their compositions. Another name used to refer to the medium-density variety is two pound foam. It has a rigid nature and has the ability to offer long term thermal resistance. The R-value of this material is in the range of 5.1 and 6 per inch.
When installing the medium-density SPF insulation up to a thickness of 50 mm, it creates an effective barricade to both air and vapor. It comes in a natural yellow color. In most countries installers of this material have to be licensed and have proper identification documents when working. In countries that manufacture the material there are regulations on how the production process is to be done.
The light-density version is also known as half-pound foam. Half-pound SPF has a spongy appearance and is semi-rigid in nature. The spongy appearance expands when it is installed to create small, open cells that are filled with carbon (IV) Oxide gas. Because the material expands when it is being installed, it is able to enter and fill crevices, holes and cracks in walls and other surfaces. It can also adhere to irregular surfaces and produce air tight insulations.
The R-value of the material is dependent on the manufacturer. However, the R-value is usually placed at 3.8 per inch. As compared to the medium-density variety the light-density variety which is unable to form a barricade against vapor. If it is installed at a thickness of more than 5.5 inches it can be able to form a barrier against air.
Half-pound SPF is used on interior walls in buildings and other structures. When installed, it reduces sound pollution by blocking and absorbing air leakage. Because of its nature, it is only recommended for use in indoor settings.
