H-Shield-NB is installed, wood side up, over metal, wood or structural roof decks. Hunter SIP/NB Panel Fasteners are required to secure the H-Shield-NB to the roof deck. Wood blocking, if necessary should be equal in thickness to the H-Shield-NB, is installed along the eaves and rake edges of the roof. The roofing system is then installed according to the manufacturers recommendations.

The incorporation of a vapor barrier or retarder within the roofing assembly is highly recommended with the project is located in Zones 4 - 8 as determined by the International Code

Council Dept. of Energy NW National lab of the United States

(map located on www.polyiso.org). Consult a licensed design professional, architect or engineer to establish whether or not a vapor barrier is necessary and to specify its type and location. This is especially important during the construction phase when excessive moisture drive is present. Hunter Panels recommends

that a dew point calculation be performed prior to the installation of any product. This calculation is based on the buildings interior

relative humidity, interior temperature conditions and outside temperature. Excessive moisture migration and temperature fluctuations during construction will potentially damage the system and cause unwanted condensation and aesthetic anomalies.
