Two most common materials such as the isocyanate and the polyol resin are being used in spray foams. The 2 materials will respond when they are being mixed together and it will enlarge thirty to sixty times it original liquid volume we spraying. The advantage of this is so useful when packaging materials and also, it forms the shape of object. Through this, there is high value in thermal insulating. So the higher the insulation value, there is more effectiveness in it.
Polyurethane is another common material being used. Its cells contain a gas of low conductivity. Polyurethane is now being used in many applications and industrial uses such as shoe soles and cushions. It was also used in airplanes and as an insulator for buildings. Spray foam insulation may block all three types of heat transfer. The conductive, radiant, and convective heat transfers.
Thermoset plastics are going to block conductive heat transfer since it has very loose molecular bonds. Also, spray cells are filled with either close air cell or open air cell foam. The thermoset foam can reflect the radiant heat due to the reflective surface of foams cell structure. A spray has the ability also to air seal. The main benefit of air sealing is to block the convective heat transfer for both exterior and interior parts.
There are a lot of uses in which these can be applied, but the two most common are for buildings and packaging applications. This is now considered as a special type of packing especially when it is mostly used for the packaging of fragile items. These items include furniture, computers, chandeliers, vases, sculptures, and other valuables. Due to its 30 up to 60 times expansion, it can also protect items in any form, size, and weight.
In buildings, this insulation is used as a replacement for fiber glasses. Using fiber glasses is used traditionally when insulating a building. The mixture of two main components, the isocyanate and polyol resin, is sprayed to roof tiles, concrete slabs, holes, and wall cavities. Polyisocyanurate and polyurethane are two types that are being used for the buildings to provide thermal insulation and to minimize air infiltration.
The spray polyurethane can be classified into two types. These are the light density open cell and the medium density close cell. These two are composed of thermoset cellular plastic that have millions of small cells.
The light density open cell is also known as a half pound foam. This is a semi firm material and its structure is like a sponge which will enlarge when installed. This also creates small and open cells that contain carbon dioxide. Because of its capability to enlarge, it can fill cracks, voids, and crevices. These are often used in inner walls because it can provide a sound reduction through blocking or absorbing the leakage of air.
Medium density close cell is frequently referred as the two pound foam. It is a firm material that contains a thermal resistance for a long term. The usual color of this is yellow. But in Richardson, TX, other types need a unique color for its identification.
Spray foams are applied in some countries to the bottom of roof tiles that have high pressure. Tiles are sealed together after spraying. Other uses of this aside from severe leaks are for a vast heat insulation of roofs.
