Anyone with interest in the sustainability and performance of Building Envelope Systems is invited to attend the next BEC-Philadelphia lunch time presentation.
ABSTRACT: Spray polyurethane has been described as a fast, cost-effective insulation, without seams or edges, that provides excellent performance characteristics (high R-value, vapor resistant, low water absorption, low air permeance, tenacious adhesion) and with it you can meet the four-barriers with just one product . . . but the reality is much different. This is the perspective of a system failure investigator. The benefits and limitations of spray-applied polyurethane foam insulation materials will be illustrated using practical examples of buildings that the presenter has investigated.
