Spray foam refers to a chemical product made by reacting two chemicals, namely, polyol resin and isocyanate. The resultant product after the reaction is capable of expanding 30-60 times when it is applied to a place. The ability to expand has allowed the material to be used in the packaging industry. When used in packaging, it is capable of offering high thermal insulating value to products. To buy Spray Foam Insulation Long Island NY should be prioritized.
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.
Spray foam insulation has several properties that make it a superior insulator in various applications. First, the material has a very high R-value. The R-value ranges between R-3.4 and R-6.7. It is also available in a wide range of densities and cel structure. Given the high R-value, the material is suited for use in residences and buildings. The material is capable of blocking the loss of heat through all the three ways of heat transfer.
There are two major types of SPF insulations, that is, light-density open-cell and medium-density closed-cell SPF. Regardless of their composition and makeup, the two types are thermoset cellular plastics that are made of millions of small cells. The medium-density variety is usually referred to as two pound foam. It is rigid in nature and offer long term thermal resistance. Its R-value ranges between 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.
Another name used to refer to the light variety is half-pound foam. Its appearance is sponge-like and the nature is semi-rigid. During installation, the spongy appearance allows it to form tiny, open cells, with carbon (IV) Oxide gas filling them. The ability of the material to expand allows it to fill any openings in the place it is installed, including holes, crevices, and cracks. It creates air tight insulations by adhering to irregular surfaces.
Manufacturers make this material with varying R-value. However, most manufacturers make the R-value to be 3.8 per inch. The half-pound SPF is not like its medium-density counterpart because it cannot form a barrier against vapor and steam. However, when installed to a thickness of over 5.5 inches, it can form a perfect 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.
