These include overall thickness of the panel, the weight of the specified cladding and the type of support provided at the base of the wall assembly. Please contact Hunter Panels for assistance with fastening rate and fastener type. Good construction practice dictates that all insulations should be protected from moisture and direct sunlight during job-site storage. Pallets of Hunter Panels Xci NB are double packaged in a UV resistant polyethylene bag. This moisture resistant package is designed for protection from the elements during flat bed shipment from our factories to the job-site. Outdoor storage for extended periods of time requires waterproof tarpaulins and elevated storage above ground level a minimum of 2". Additionally, we recommend slitting the bundle packaging vertically down the center of the two short sides to prevent moisture accumulation within the package. Post-Installation Exposure Xci NB is not intended to be left exposed for extended periods of time. During the time between the installation of the Xci NB and the application of the exterior cladding it is recommended that the WRB be installed as soon as possible. If the WRB is not being installed right away it is recommended that the Xci NB be protected from excess moisture and UV. All unfaced foam exposed directly to daylight can be taped with a compatible waterproof tape and the edges of the boards can be buttered with a sealant that is compatible with the WRB. Weather Resistant Barrier (WRB) The incorporation of a WRB is a critical element of a wall assembly. Hunter requires a vapor permeable WRB be applied to the wood exterior of Xci NB. A design professional familiar with local code requirements should specify the selection and placement of any additional WRBs. A single source option is available: Xci VP-SA WRB. Please contact Hunter Panels for more details on this product. Warnings and Limitations Insulation must be protected from open flame.
