There are two big variables to understand and contemplate when comparing open cell and shut mobile spray foam. The to start with is the actual physical make-up of the foam. It is either open up-mobile foam, where the compact cells of the foam are not wholly closed. They are open and air fills all of the very small air pockets in the substance. This makes the foam structurally weaker and much fewer drinking water resistant than shut-cell foam.

Shut-mobile foam is also created up of little foam cells BUT its very small foam cells are closed and packed collectively. They are stuffed with a gas, not air, which can make the foam increase, increase and turn into a a lot larger, extra dense and completely waterproof insulator.

Weighing a person remedied cubic foot of foam material provides us a measurement of its density. Open up cell foams commonly weigh in at .4 to .5 lb./cu. ft. Shut mobile foam, employed for insulating applications, have a density of 1.7 lb./cu. ft. to 2. lb./cu. ft. Roofing applications commonly use an even increased density foam to guidance bigger loads. The increased the density the foam the stronger it will be. A lot of polyurethane foams can turned into decorative moldings and painted/stained to look like wooden. There are “super dense” foams with densities of 30 lb./cu. ft. to 40 lb./cu. ft.

There are various strengths for using closed-mobile foam as opposed to open-cell foam together with its structural integrity, greater R-benefit, and its ability to wholly seal air leaks and protect against water infiltration. The disadvantage of the shut-cell foam is the price, because it requires additional product as it incorporates no air. The choice of which foam to use will also be centered on some software certain demands these kinds of as load abilities, vapor/drinking water infiltration resistance, house constraints, and so on. Open up-cell Spray Foam ordinarily has an R-price typical of 3.5 per inch h2o is employed as the blowing agent. Closed-cell Spray Foams Insulation generally has an R-value of around 7. for every inch and utilizes higher R-value blowing agents.
