Closed and Open Cell Polyurethane Spray Insulation - Dissimilarities
Polyurethane spray foam is a kind of creation that is formed from big cycles of non organic elements that are unique mixtures. When this material is mixed with several other substances, it can be utilized for spray insulation. There are two kinds of polyurethane spray insulation, the closed and open cell spray insulation. Further in the article, I have explained the differences that exist in these two types of polyurethane spray insulation.
Taking the structure into consideration, the open spray insulation has got small gaps in between the specks of spray that are not closed to air. In case of the closed cell polyurethane spray insulation, these tiny gaps are shut and packed with each other.
Coming to the appearance, the closed ones are much tougher as well as dense. On the other hand the open spray insulation is not at all hard and has a feathery look.
Insulation is ranked on the basis of its R value i.e. blocking power of the insulation for the obstruction heat. The closed cell polyurethane spray insulation has got an R value of 7/inch whereas on the other hand the open one has 4/inch. This clearly shows that the closed ones are much more efficient at maintaining comfortable temperature in the house during the winter season.
As compared to the closed insulation, the open cell polyurethane spray insulation provides more resistance against loud sound.
When we talk about dampness then the open spray filling has not got the ability to prevent moisture that well and that's why they are not efficient to stop leakage. On the other hand the closed ones perform better in this scenario.
As the closed cell polyurethane spray insulation is stronger as compared to open filling, more elements are required to insulate a place. That is why the closed cell filling is costlier than the open insulation.
