Foam insulation in general is viewed as an increasingly popular choice for building and renovation projects, thanks in large part to its terrific energy-saving properties. While most commonly referred to as spray foam, this type of insulation can actually be applied in two formats: spray and injected.
While the long-term benefits are the same (meaning, energy efficiency and reduced utility bills), the application process differs among the two formats.
Injected foam insulation is often the better choice in retrofit situations—meaning, when the foam is being used as an upgrade or enhancement to an existing structure. That’s because the injection process is more conducive to environment involving a closed or contained space, whereas sprayed materials are better suited to open spaces. The injected formulation of foam insulation is a convenient approach to filling cracks and crevices, and offers a very effective way to eliminate drafts and leaks.
Injected foam expands more slowly and therefore takes slightly longer to set up. There are also some important specific considerations that must be addressed when applying foam via the injection process. For example, it is critical that the ratio of combined materials is perfectly accurate, and the thickness of each layer must also be just right.
Of course, the proper supplies are also a necessity to perform these projects, which is why many contractors turn to Intech Equipment & Supply for all of their spray foam equipment needs.
