RapidLock is a hook and loop attachment system powered by VELCRO® Brand Securable Solutions. Versico’s insulation boards act as the hook while the VersiFleece®membranes act as the loop, creating the industry’s fi rst adhesive-less, fully adhered attachment system. RapidLock provides a fully adhered roofi ng system without VOCs or installation temperature restrictions. Versico’s SecurShield HD Composite RapidLock Polyiso is a rigid roof insulation panel composed of a top layer of high-density, closed-cell foam, and a bottom layer of 20 psi closed-cell foam. Both layers are laminated to a premium-performance, coated glass mat facer (CGF).
