Foster® 95-55 Sealant is a one-component, butyl-based sealant primarily employed as a vapor barrier sealant within the joints of cellular glass, polyisocyanurate (PIR), urethane, and phenolic foam board stock insulations. This sealant remains non-skinning and does not dry within the joint, which permits thermal cycling through a broad spectrum of temperatures without issue.
