Chem-Seal 2 lb Foam Product Description: Chem-Seal is a spray applied, 2 lb density polyurethane foam insulation. It creates a seamless monolithic insulating envelope that adheres tenaciously to virtually any surface, smooth or irregular. Features & Benefits: provides the most effective "in-place" insulation eliminates convection currents around insulation (This can reduce "R" value in insualation by 50% or more) provides gap-free insulation seals around anomalies and obstructions in walls minimizes the effects of thermal bridges strengthens and stiffens stud walls provides high "R" value of 6 per inch cost effective: fast one-step application cuts costs when compared to separate applications of air barrier, insulation & vapour retarder limits air leakage (2" thickness has a rating of 0.000167 l/s/m²) retards vapour transfer (a 2" thickness has a perm rating of 19 mg/Pa/s/m²) high strength, self-supporting, fills cracks and bridges gaps flows around structural steel maintains continuity through changes in plane provides airtight seal around brick ties seals mechanical and electrical penetrations works effectively in any position within the building envelope Uses: Chem-Seal 2 lb foam performs as an insulation, air barrier and vapour retarder on any surface, smooth or irregular (Industrial/Commercial/Institutional) ABOUT US | WHAT'S NEW | CONTACT US | WATERPROOFING | AIR/VAPOUR BARRIERS | ROOFING | SEALANTS | DAMPPROOFING | DRAINAGE MEMBRANES | HOME
