Open cell and closed cell are two types of different foams available. Sprayed foam is used as a liquid which contains a polymer and a foaming agent. By acting as a wind and air barrier,Types of Spray Basotech Foam Insulation Articles it often eliminates the need for separate air tightness. Spray foam insulation does not degrade or shrink. Insulation of spray foam insulation requires a skill trainer although most of the products are ready made available.
The cost of spray foam at the time of installation depends on the thickness of the wall and the type of foam and it does not include any kind of operational cost. The warranty period of this spray foam insulation depends on the manufacturer and It may be either limited or lifetime warranty. Various benefits of spray foam insulation are: although it costs than traditional Bat insulation but acts as an air barrier and Bat insulation eliminates the steps of air tightness dealing. Since most of the products are ready made available so less number of specialized contractors are required and it also reduces the construction time period.
The basic difference between the two types of spray foam insulation is: the first and the foremost reason is the nature of the foam. In case of open cell, the tiny cells of the foam are not completely closed and they are broken and air fills all of the open space inside the material and because of this the foam gets weaker or softer. There are many advantages of closed cell foam over open cell foam. The disadvantage of the closed cell foam is that it is denser and it requires more material and thus more expensive.
One should always contact the supplier for performance and application data on their specific material. Open cell SPF has an R-value around 3.5 per inch and typically uses water as the blowing agent and closed cell SPF has an R-value around 6.0 and it uses R-value products. Spray foam insulation is a superb product and there are insulation materials available for metal buildings as well and it is progressing day by day.
