Hunter Panels: Energy Smart Polyiso
Mount Desert Island Biological Lab: Bar Harbor, Maine
New Building on the MDIBL campus designed and built to accommodate the growing number of researchers flocking to the site each year uses Hunter Panels for green roof.
Roof Installer: Roof Systems, Main
July 2008: The new, 18,000-square-foot building officially opened
2009: Awarded "Gold" LEED Building Certification
Roof Details:
Roof Systems used 7,800 square feet of Hunter’s insulation products to the 8,700-square-foot shingled portion of the building’s roof. They began by laying down a four-inch layer of standard polyiso over top of the lab’s 22-gauge steel roof deck. Next they installed a four and one half inch layer of Hunter’s innovative H-Shield-NB, staggering the seams from the first layer to reduce thermal bridging and further increase the rooftop’s overall energy efficiency. Consisting of a four-inch layer of polyiso laminated to a heavy-duty, 5/8-inch piece of oriented strand board, H-Shield-NB eliminates the need to install an additional nailer on top of the insulation before attaching the finished roofing material.
Hunter’s four-inch polyiso provides an R-value of 25, while the four and one half inch H-Shield-NB offers an additional R-value of 25.6. Combined, the two layers of insulation created a rooftop with an R-value of over 50, more than enough to help the laboratory reduce its heating and cooling costs.
Besides energy efficiency, Hunter’s polyiso also features other properties that make it good for the environment and good for the lab. The H-Shield NB used for this project featured OSB that was certified by the Forest Stewardship Council (FSC), a non-profit organization devoted to encouraging responsible management of the world’s forests. Lumber with the FSC label, such as the OSB used on the laboratory’s rooftop, was harvested in a sustainable manner with little impact on the environment.
Other sustainable attributes of Hunter’s polyiso include a manufacturing process that features zero ozone depleting potential (ODP), is CFC-free and meets all applicable EPA standards. Hunter’s polyiso also features an FM Class 1 uplift rating and UL Class A fire rating, resulting in a rooftop that provides superior protection against anything Mother Nature has to offer.
In order to fasten the insulation to the rooftop, Roof Systems utilized specialized 10-inch fasteners developed specifically for use with Hunter’s H-Shield-NB, Cool-Vent™ and Cool-Vent II. The fasteners offer increased pullout resistance and are FM approved. They do not require the use of washers or fastener plates, which reduces costs and speeds up installation. The 10-inch screws were installed through the H-Shield-NB and standard polyiso and attached to the building’s metal decking.
After all of the insulation was fastened to the deck, Roof Systems installed a layer of ice and water shield over the entire roof surface and then covered it with a 50-year asphalt shingle. They completed the roof installation by installing a 24-gauge, white, Kynar-coated flashing material that provides a long-term finish and increases the sustainability of the entire project.
