What is gun grade expanding foam?

Gun Grade Expanding Foam is a quick setting polyurethane-based foam which expands greatly on application and yields up to 50 times original can contents. It fills irregular gaps, fixes framework, insulates and sound deadens.

Is expanding foam structural?

Spray foam also adds structural strength due to its second property advantage. Spray foam insulation expands as it comes into contact with the air and hardens as it dries, resulting in a transformation from liquid to a rigid state. So, the answer is yes: spray foam insulation does add structural integrity.

Can expanding foam support weight?

First, it is lightweight, which makes it a good choice in situations where the weight of concrete would further damage a structure. Second, spray foam insulation is cost-effective.
