ISSUED: 04-15-14 SUPERSEDES 04-11-14 WWW.ROXUL.COM TECHNICAL COMMUNICATION DESIGN BASIS 1. MECHANICAL ATTACHMENT For permanent attachment, ROXUL stone wool (mineral wool) insulation should be mechanically attached or pressure held by supporting members. 6. WIND LOAD (LIVE LOAD) Fastening connections should be designed to withstand horizontal loads imposed by wind pressures. Wind loads often govern lateral load scenarios 2.
ISSUED: 04-15-14 SUPERSEDES 04-11-14 WWW.ROXUL.COM Plain Insulation 1. APPLICATIONS Exposed Exterior Insulation Basements (Inside / Outside) Parking Garages Acoustic Panels 2. EXPOSED INSULATION ROXUL stone wool insulation is not intended to be left exposed to the elements. Cladding should ideally be installed immediately after insulation attachment.
ISSUED: 04-15-14 SUPERSEDES 04-11-14 WWW.ROXUL.COM Strapping 1. GENERAL Strapping, attached to the building structure, will act like giant clamps to hold insulation in place. ROXUL insulation boards will be permanently mechanically supported by the strapping attachment if the attachment is designed to withstand live loads and total applied dead loads.
ISSUED: 04-15-14 SUPERSEDES 04-11-14 WWW.ROXUL.COM Masonry Ties 1. GENERAL Wedges / clips installed over masonry ties can be used to attach ROXUL insulation boards. Non-proprietary or proprietary masonry ties can be used. 2. DESIGN Spacing and design of the masonry tie pattern should follow accepted practice and be adequate to support wind and dead loads.
ISSUED: 04-15-14 SUPERSEDES 04-11-14 WWW.ROXUL.COM Clips & Girts 1. GENERAL Proprietary clips / brackets or nonproprietary stand-offs designed to support vertically installed z-girts or L-channels can be used. Insulation is not required to provide any structural support with this type of system. 2. THERMAL BRIDGING & Z-GIRTS ROXUL does NOT recommend using z-girts through the full thickness of insulation. Clips, brackets or stand-offs should be used to minimize thermal bridging. TECHNICAL COMMUNICATION 5.
