RWP Roof/Wall Panel

Thermal Properties - Test Data

Description:	The RWP Panel functions well as a roof or wall panel when used in conjunction with pre-engineered building framing systems. The product features an over-lapping major rib at the panel sidelap. Exposed fasteners are located in the major ribs when the panel is used as a roof and in the pan when the panel is used in a wall application. This Tecfoam panel is filled with non CFC polyurethane modified isocyanurate foam achieving R-values up to 35.7.
Dimensions:	Nominal 36" coverage; Thickness (T) – 1-½", 2", 2-½" and 3". Contact IPS regarding the availability of 4" and 5" thick panels.
Material:	Exterior - 26 ga. steel (std). 24 and 22 ga. also available. Interior - 26 ga. steel (std). 24 and 22 ga. also available.
Finish Options:	Exterior - Galvalume Plus® Signature® 200 (silicone polyester) Signature® 300 (Kynar 500®/Hylar 5000®) Interior - USDA White (standard) Signature® 200 (silicone polyester)
Colors:	IPS Panel Color and Finish Guide
Texture:	The exterior skin is smooth as a standard and available embossed as an option. The interior skin is embossed only.
Length:	The maximum recommended length is 35' 0". Contact IPS for panel length options.
Fasteners:	Exposed - hex head with neoprene washers.
