General Information on Spray Polyurethane Foam (SPF)

Low-Pressure SPF SPF Spray polyurethane foam

Low-pressure SPF SPF Spray polyurethane foam systems are two-component polyurethane foam products. They are typically delivered to the job site in pressurized canisters (~250 psi Psi Pounds per square inch ), dispensed though unheated hoses through a disposable mixing nozzle system, and applied as a froth-like material to substrate. This type of SPF SPF Spray polyurethane foam product is typically used for large sealing and small-scale insulation products.

 

High-Pressure SPF SPF Spray polyurethane foam

High-pressure SPF SPF Spray polyurethane foam systems are two-component polyurethane foam products. They are typically delivered to the job site in unpressurized drums or totes and dispensed by a proportioner pump where heat and pressure are added. These chemicals travel through heated hoses to a spray gun where the material is aerosolized during application. This type of SPF SPF Spray polyurethane foam product is typically used for larger insulation applications.

 

Note on SPF SPF Spray polyurethane foam Delivery Methods

Once installed, there is essentially no difference in product performance between low- and high-pressure foams. It should be noted that the main differences between the delivery methods are in capital equipment investment, application rate, and PPE PPE Personal protective equipment requirements.

 

Installer Training

Applicators should obtain training from the suppliers of SPF SPF Spray polyurethane foam to help assure installation quality and use of all equipment as well as safe handling, use, and disposal of all chemicals used in the process. Spray Polyurethane Foam Alliance ( SPFA SPFA Spray Polyurethane Foam Alliance ) also offers additional training and accreditation for high-pressure SPF SPF Spray polyurethane foam applicators.

 

Manufacturer Installation Instructions
