Evergreen offers various coating products to our clients, including intumescent coatings and vapor retardants.
Intumescent coatings are fire retardant materials applied over spray foam in very specific interior configurations per building code standards.
The leading spray foam system manufacturers with which Evergreen works offer fire-resistant and third party-tested spray foam products designed to eliminate the use of intumescent coatings.
In context, spray foam products are certified by third party testing agencies to prove they are Class I fire-rated materials that have lower smoke spread and flame development performance characteristics than the wood standard to which these products are compared.
Bottom line, spray foam is thoroughly and expertly tested to be a safe product.
