HR Series (HR3-W/HR3-W with InnovaCELL™ Technology)

HR3-W is the High Rib Wall Panel with a 40-inch module in the AWIP HR Series, also offered as HR3-W with InnovaCELL Technology. AWIP lists it as a high-rib panel for wall applications with high R-values and as the wall version of the HR3 roof panel. It belongs to the insulated metal panel range.

The profile has an aesthetic similar to classic board and batten, produced in a single pass on the wall. The wall is a single component with an exterior face, a weather barrier, insulation and a vapor barrier. The panel is fastened with exposed through-fasteners for retrofit or new construction.

• Module width: 40 inches (1016 mm)
• Thickness: 1.5, 2.5, 3 or 4 inches
• Length: 8 feet (2.4 m) minimum to 40 feet (12.2 m) maximum
• Exterior profile: smooth, trapezoid
• Interior profile: embossed, lightly planked, Mesa rib
• Side laps: trapezoidal overlap on the exterior, shiplap on the interior

The core is polyisocyanurate (PIR). The HR3-W exterior skin is 26 gauge G90 galvanized or AZ50 Galvalume steel, with 24 and 22 gauge optional. The HR3-W interior skin is 26 gauge G90 or AZ50, with 24 and 22 gauge optional, or 26 gauge 304 2B stainless steel for interior applications only.

Published global warming potential for the HR3-W 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 HR3-W is 7.2 per inch at 75°F mean temperature and 8.2 per inch at 35°F mean temperature, by ASTM C518. The HR3-W U-values come from ASTM C1363 tests at 2 and 4 inch thicknesses.

The HR3-W interior is painted Imperial White, the AWIP standard interior finish. Embossed metal is standard on AWIP wall panels, with non-embossed wall finishes available on request depending on color, gauge and end use.

Exterior colors come from the AWIP color chart, and color chips are available on request.
