Equipment used for applying polyurethane foam insulation typically consists of a system with two tanks, hoses, and a spray gun. One tank holds isocyanate and the other polyol resin. These two components are mixed at the spray gun, expanding rapidly upon contact to form the insulating foam. This equipment allows for precise application in various locations, creating an airtight and water-resistant seal.
The ability to create seamless insulation contributes significantly to building efficiency. Structures insulated with this technology experience reduced air leakage, leading to lower energy consumption for heating and cooling. This, in turn, translates to lower utility bills and a smaller carbon footprint. Furthermore, the application process is relatively quick, minimizing disruption during installation. The development and refinement of this equipment represent a significant advancement in building science, moving beyond traditional insulation methods like fiberglass batts.
