SprayWorks Conducts Spray Foam Testing on Behalf of Natural Polymers

SprayWorks Equipment recently worked with Natural Polymers to test spray foam materials from across the country. The application portion of the test was conducted at the SprayWorks Equipment facility in Kent, Ohio. After Owens Corning’s 2022 acquisition of Natural Polymers, an Illinois-based spray foam manufacturer, the company sought a location to carry out customer focused learnings.

Can Spray Foam Insulation Be Applied in Cold Weather?

How cold is too cold for spray foam?

Depending on the type of spray foam used, processing temperatures are typically between 60-90º inside the barrel. For substrate temperatures, roofing is generally 45-180º, while interior foam can be applied from sub-zero temperatures all the way up past 100º.

If you are working in a colder environment, alternate low temperature spray foam that is designed as a winter blend, will be required. Cold weather spray foam is specially formulated to have a faster reaction time, preventing delimitation from the substrate. Open cell foam is not capable of being winter blend spray foam insulation, only closed cell foam. While open cell doesn’t have a winter blend, with a flash coating of 1/8 inch to ¼ inch, it can be sprayed on substrates down to about 10 degrees.
