HR Series (HR5-W/HR5-W with InnovaCELL™ Technology)

HR5-W is the High Rib Wall Panel in the AWIP HR Series, also offered as HR5-W with InnovaCELL Technology. It is the wall version of the HR5 roof panel and is part of AWIP's insulated metal panel range. The panel is fastened with exposed through-fasteners and is used in retrofit and new construction.

The trapezoid rib gives a look similar to classic board and batten in a single pass on the wall, with depth and shadow lines. The wall is a single component that includes the exterior face, a weather barrier, insulation and a vapor barrier.

• 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
• Exterior side lap: trapezoidal overlap
• Interior side lap: shiplap

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

Published global warming potential for the HR5-W is 5.6 to 10.6 lb CO2eq per square foot (27.5 to 51.5 kg CO2eq per square meter).

The nominal R-value of the HR5-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 HR5-W U-values come from ASTM C1363 tests at 2 and 4 inch thicknesses.

• 1.5 inches: R-10.8 at 75°F mean and R-12.3 at 35°F mean
• 2.5 inches: R-18.0 and U-0.087 at 75°F mean; R-20.5 and U-0.078 at 35°F mean
• 3 inches: R-21.6 and U-0.073 at 75°F mean; R-24.6 and U-0.062 at 35°F mean
• 4 inches: R-28.8 and U-0.040 at 75°F mean; R-32.8 and U-0.032 at 35°F mean

• ASTM E84: flame spread index 25 or less, smoke developed index 450 or less
• NFPA 285: passed
• NFPA 286: passed, maximum 4 inches thick
• NFPA 268: assembly tested meets the requirements of the standard
• ASTM E331: no uncontrolled water penetration at 6.24 PSF for 2 hours
• ASTM E283: air leakage under 0.03 CFM per square foot including a stack joint, at 6.24 PSF

Structural performance by ASTM E1592 is published in the span tables.

The HR5-W wall panel has an embossed exterior as its standard surface, and smooth wall finishes may be available on request depending on color, gauge and end use. Its standard interior paint finish is Imperial White. Multilayer coil coat systems for aggressive environments are offered beside the standard paints on the HR5-W, with color chips on request.

• HR Series HR3-W: an low-cost wall panel with high R-values
• Heavy Embossed HE40
• AdobeTexture HE40A
• HR5: the roof version of the HR5-W

The HR5-W gallery on the manufacturer's site shows installations in cold storage and other building types.

The HR5-W is a composite panel: the exterior face, weather barrier, insulation and vapor barrier form one component. The interior surface is washable and replaces loose insulation or sheathing on the wall.
