H-Shield NB

H-Shield NB is a rigid roof insulation composite panel composed of a closed cell polyisocyanurate foam core manufactured on-line to a fiber reinforced facer on one side and either 7⁄16″ or 5⁄8″ oriented strand board (OSB) on the other. H-Shield NB can also be manufactured off-line using an FM approved adhesive.


Features and Benefits

  • Manufactured with NexGen Chemistry: Contains no CFCs, HCFCs, is Zero ODP, EPA Compliant, and has virtually no GWP
  • A superior combination of high insulating properties and a nailable surface
  • Suitable for new construction and re-roofing on both commercial and residential projects
  • Incorporates APA-TECO Rated Exposure 1 OSB
  • The edges of the wood panels are rabbeted to allow for expansion and contraction of the wood, the foam edges shall be installed
    tightly to achieve thermal integrity across the entire roof deck
  • Also available as a non-rabbeted panel upon special request only
  • H-Shield NB is also available bonded to plywood in an off-line process
  • Hail Rating: SH-1

WARNINGS

Insulation must be protected from open flame and kept dry at all times. Install only as much insulation as can be covered the same day by completed roof covering material. Hunter Panels will not be responsible for specific building and roof design by others, for deficiencies in construction or workmanship, for dangerous conditions on the job site or for improper storage and handling. Technical specifications shown in this literature are intended to be used as general guidelines only and are subject to change without notice. For more information refer to the Storage and Handling Technical Bulletin at www.hpanels.com, or refer to PIMA Technical Bulletin No. 109: Storage & Handling Recommendations for Polyiso Roof Insulation at www.polyiso.org.

INSTALLATION

Shingles, Tiles, Slate, Metal and Membrane Roofing

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 and should be installed along the eaves and rake edges of the roof. The roofing system is then installed according to the manufacturer’s recommendations.

H-Shield NB may be adhered to a properly prepared cementitious deck (with a full mopping of Type III or Type IV asphalt or a low rise adhesive) only when manufactured online.  All H-Shield NB manufactured off-line must be mechanically attached.


The Use of Synthetic Underlayments

The use of synthetic underlayments is becoming an industry norm (for steep slope applications).  Hunter Panels strongly suggests the use of a synthetic underlayment under asphalt shingles unless otherwise specified by the shingle manufacturer. Synthetic underlayments provide excellent water resistance and absorb no moisture.


Vapor Retarders

The incorporation of a vapor barrier or retarder within the roofing assembly is highly recommended when 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 at 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 within the system. 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.


Fastening Guidelines

Hunter Panels requires the use of the Hunter Panels SIP SD Panel Fastener for steel deck applications and the SIP WD for wood deck applications. See Fastening Pattern Guide for recommended fastening patterns.


When H-Shield NB with a foam thickness greater than 3.5″ is specified, Hunter Panels recommends the installation of a two layer system with staggered joints.

Our Warranties are Second to None

DMI total system warranties protect "all aspects" of your metal envelope system. Whether that be the watertighness, the material or the finish. When looking at the warranties for your system it is important to note that not all warranties are created equal. Be sure to read the fine print to find out about any limits or exclusions. Are you truly getting a warranty or is it just a glorified maintenance agreement? Is the warranty covering all aspects of your Metal Envelope system? Is it guaranteeing that your project is being installed with the best quality? With DMI Total System Warranties you can feel confident that you are getting the best quality and guarantee in the industry!
