Tests Verify Airtightness of Spray-Foam Alternatives

With attention to installation quality, Knauf’s EcoSeal and Owens Corning’s EnergyComplete demonstrate that they can create air barriers and reduce use of SPF.

Two products—EcoSeal from Knauf and EnergyComplete from Owens Corning—have been on the market for several years as spray-applied latex sealants for making building envelopes airtight during new construction (see Spray-Applied Latex: A New Tool for Air-Sealing). Until recently, however, we haven’t had solid data on exactly how well they work—a key consideration, especially for projects that want to use them to reduce or eliminate use of spray polyurethane foam (SPF) and its health and climate impacts.
