With proper application, Spray Foam will last the lifetime of your home. Even roofing applications will last upwards of 30 years, with proper long-term maintenance. Spray Foam insulation adheres extremely well to virtually all substrates, and maintains its rigidity once dry.

Does spray foam disintegrate?

Studies on commercial roofs have found that spray-polyurethane foams age well, even in extreme heat and moisture. They retain their physical properties well, absorb little moisture (0% to 2%), and require recoating with ultraviolet (UV) protection every 10 to 15 years to remain sustainable for the long term.

Does expanding foam deteriorate over time?

To answer your question, how long does spray foam last? Properly installed, spray foam insulation does not deteriorate, it will last for the duration of the home. That fact combined with the energy savings will more than pay for the spray foam insulation cost.

Does XPS lose R-value over time?

The trapped gases in the cells of polyiso and XPS foam assist to provide an initial high R-value. During the life of these foams, air from the atmosphere diffuses in and the trapped gases diffuse out. The result is polyiso and XPS lose R-value over their lifetime.

What is the R-value of 4 inches of spray foam?

Spray Foam Insulation R-Value

Open cell spray foam insulation is R-3.6 to R-3.9 per inch. This R-Value is normal for open cell spray foam.

Is closed cell spray foam worth the money?

Closed-cell spray foam is the king of the insulations when it comes to both R-value per inch and cost. Nothing else comes close, really. Unlike its open-cell cousin, closed-cell spray foam is not vapor permeable and will not hold water. This makes it an excellent option in case of water intrusion.

But that only works if the installer can get it into the places where most of the air leakage happens. In an attic, the eaves are one of the most critical places to get good coverage with the foam.

Does foam deteriorate in water?

There is no evidence to suggest any possible damage or deterioration is caused as a result of using spray foam on damp surfaces. Even if the application area gets wet quite often, the water-resistant nature of closed-cell spray foam in particular will ensure there are no issues.

Can closed cell spray foam be left exposed?

Can Spray Foam Be Left Exposed? The quick answer is yes and no, because spray foam can be left exposed in some areas of the home with others require a thermal barrier according to the code.

Is expanding foam water proof?
