Johns Manville (JM), a Berkshire Hathaway company and leading building products manufacturer, announces the launch of JM QuickFoam® Adhesive, a two-part, low-rise polyurethane foam adhesive for attaching fleece-backed single ply membranes to insulation boards, insulation boards to each other, or direct to the deck. This new adhesive helps contractors work faster while delivering enhanced performance and strength.  
 
JM QuickFoam® retracts as it cures; this feature eliminates post-rise and reduces telegraphing through the membrane, ensuring a smooth, clean appearance.  “Retraction technology allows contractors to install membrane, insulation and cover boards with minimal ballasting required,” said Polyiso Product Manager Jeff Job. “Once applied, they can walk-in the board or membrane, roll it with a 150 lb. roller and let the bond do the rest.  Plus, it’s compatible with all major spray rigs, so it’s easy for contractors to make the switch."
 
Moreover, JM QuickFoam® remains flexible once cured, providing effective impact absorption. Soon, look for JM to offer enhanced hail protection capabilities with roof systems utilizing JM QuickFoam®. This includes Very Severe Hail (VSH) rated systems, which are already available through FM.  
 
JM QuickFoam® is compatible with several applications, making it a versatile solution for fleece-backed membrane, insulation and cover board securement. It can be used with the following insulations, cover boards and substrates: polyisocyanurate; HD wood fiber; perlite; HD Polyiso; gypsum; concrete; treated plywood; cementitious wood fiber plank; base sheets; gypsum; and some existing smooth-surfaced asphalt (per inspection).
 
The product is currently available in three formats: cartridges, 15- and 50-gallon drums. Five-gallon bag-n-box and canisters will be available soon.
