Ventilation Considerations For Spray Polyurethane Foam: Guidance On Ventilation During Installation Of Interior Applications Of High-Pressure Spray Polyurethane Foam 

This document is intended to provide general guidance on ventilation during installation of interior applications of high-pressure spray polyurethane foam (SPF) in new residences and buildings and during renovation and weatherization projects in existing homes and buildings. Each jobsite must be evaluated to determine appropriate ventilation system design.

SPF is a widely used and highly effective insulation and sealant material that is spray-applied to walls, ceilings, attics, basements, and crawl spaces. Application of SPF can seal the building enclosure below the minimum ventilation rates required by building codes or recommended design requirements. This document does not discuss permanent mechanical ventilation systems, but in certain cases, the use of such systems may need to be considered. Consult with a design professional to determine if permanent mechanical ventilation is appropriate.
