Interior Partition (IP44/IP44 with InnovaCELL™ Technology)

Interior Partition IP44 is an AWIP panel for interior partition walls and ceilings, also offered as IP44 with InnovaCELL Technology. It is part of AWIP's insulated metal panel range for controlled environments and is used in washdown areas where frequent cleaning is needed. The manufacturer marks the IP44 is for interior applications only.

The wide 44-inch module reduces the number of panels. The surface is bright, clean and uniform, and it is washable.

• Module width: 44 inches (1118 mm)
• Thickness: 2, 2.5, 3, 4, 5, 6 or 8 inches
• Length: 8 feet (2.44 m) minimum to 50 feet (15.24 m) maximum
• Side lap: double tongue and groove
• Exterior profile: embossed, lightly planked, Mesa rib, with flat as an option
• Interior profile: embossed, lightly planked, Mesa rib, flat

The core is polyisocyanurate (PIR). Both the exterior and interior face skins are 26 gauge G90 or AZ50 steel, with 24 and 22 gauge as options or 26 gauge 304 2B stainless steel. PVC and stainless steel finishes are the finishes offered for the IP44.

Published global warming potential for the IP44 is 5.6 to 10.5 lb CO2eq per square foot (27.2 to 51.2 kg CO2eq per square meter).

The same panel is configured as a partition wall or as a ceiling panel, and it can be combined with other AWIP panels and accessories into a complete controlled-environment system. Separate load span tables are published for each of these configurations.

The IP44 exterior and interior profiles are embossed, lightly planked, Mesa rib, with a flat option. Imperial White is the standard interior paint. PVC and stainless steel are the offered finishes.

The 44-inch module reduces the number of panels. The panel is configured as partition walls or ceiling panels and combines with other AWIP panels, accessories and products into a system for controlled-environment applications. It serves washdown areas, such as food processing and cold storage settings among its listed markets.
