HR Series (HR5/HR5 with InnovaCELL™ Technology)

HR5 is the High Rib Roof Panel of the AWIP HR Series, also offered as HR5 with InnovaCELL Technology. It is an exposed-fastener insulated metal panel roof for retrofit and new construction. The roof is a single component that includes the exterior face, a weather barrier, insulation and a vapor barrier.

The interior surface is washable. The related HR5-W is the wall version, and the HR3 is the other roof panel in the series.

• Module width: 40 inches (1016 mm)
• Thickness: 1.5, 2.5, 3, 4, 5 or 6 inches
• Length: 8 feet (2.44 m) minimum to 50 feet (15.24 m) maximum
• Exterior profile: trapezoid
• Interior profile: embossed, lightly planked, Mesa rib
• Exterior side lap: trapezoidal overlap
• Interior side lap: shiplap
• Minimum slope: 1:12

The core is polyisocyanurate (PIR). The HR5 exterior skin is 26 gauge G90 galvanized or AZ50 Galvalume steel, with 24 and 22 gauge optional. The HR5 interior skin is 26 gauge G90 or AZ50, with 24 and 22 gauge optional, or 26 gauge 304 2B stainless steel for interior applications.

Panels are fastened with exposed through-fasteners. Published global warming potential for the HR5 is 5.6 to 10.4 lb CO2eq per square foot (27.3 to 50.9 kg CO2eq per square meter).

The nominal R-value of the HR5 is 7.2 per inch at 75°F mean temperature and 8.2 per inch at 35°F mean temperature, by ASTM C518. The HR5 U-values come from ASTM C1363 tests at 2, 4 and 6 inch thicknesses and are not given for the 1.5 inch panel.

• Texas Department of Insurance RC-683

The HR5 roof panel has a smooth, non-embossed exterior as its standard surface. Imperial White is its standard interior paint. Multilayer coil coats are offered beside the standard paints, and color chips are on request.

• HR Series HR3-W: an affordable wall panel with high R-values
• Standing Seam SR2: a roof panel
• OneDek: a low slope roof deck panel with with a 20-year deck-through-membrane weathertightness warranty available

The HR5 is a composite panel. The exposed through-fasteners give an industrial look to the roof. The design is weathertight and suits both retrofit and new construction.
