Versico's RapidLock (RL) Roofing System is a revolutionary membrane attachment method that provides a fully adhered system without the use of adhesives. RapidLock is a hook and loop attachment system powered by VELCRO Brand Securable Solutions. Versico's RL insulation boards act as the hook while the VersiFleece membranes act as the loop, creating the industry's first adhesive less, fully-adhered attachment System. Versico's SecurShield HD RapidLock Polyiso is a rigid roof insulation panel composed of a high-density, closed-cell polyisocyanurate foam core laminated to a premium-performance coated glass mat facer (CFG). RapidLock provides a fully-adhered roofing system without VOCs or installation temperature restrictions.
