Professional Sprayed and Injected Foam (Micro Course)

(0.8 CEU; 50 minutes) Professional installers spray foam on surfaces and inject foam into cavities. Sprayed and injected foam are excellent choices for some applications. Learn from a few examples. Spray foam is by far the most common installation. And you can observe the coverage of spray foam. Injected foam is more of an unknown because installers inject it into closed cavities. Both types of liquid foam require a precise mixture and a narrow temperature range. Shrinkage, voids, and cracking can be a problem. Although sprayed and injected foam in this course is low-density polyurethane foam, except for the final video, which features high-pressure high-density polyurethane foam.
