EWP Wall Panel

Thermal Properties - Test Data

Description:	EWP panels offer contemporary styling in an easily installed product. The profile gives any building a strong vertical accent that is ideal for pre-engineered and conventional building construction. Minor flutes in the flat surface of the profile (EWP-F) are standard and are designed to aid in reducing the potential for waviness or oil canning. The panel is also available without the minor flutes (EWP-P) as an option. This Tecfoam panel is filled with non CFC polyurethane modified isocyanurate foam achieving R-values up to 34.6.
Dimensions:	Nominal 36" coverage; Thickness (T) – 2", 2 ½", 3", 4" and 5".
EWP- F
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 - 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 and interior skins are embossed only.
Length:	The maximum recommended length is 30' 0". Contact IPS for panel length options. IPS offers standard details for stack joint applications for walls over 30' 0" high.
Fasteners:	Concealed, 14 ga. steel clip.

Test Data

Test	Purpose	Procedure	Results
Thermal Resistance	Determines insulating properties of the panels	ASTM C236 Guarded Hot Box	Good R values for an HCFC Foam System (see published values for panel type and thickness)
Air Leakage	Measures air leakage through the panel joints	ASTM E283 Chamber Method	The leakage rate for panel will not exceed 0.01 CFM/SF at 40 psf pressure differential
Water Penetration	Measures water leakage through the panel joints	ASTM E331 Chamber Method	No water penetration at pressure differential of 50 psf
Strength	Determines the load/span properties of the roof and wall panels	ASTM E72 Chamber Method	Panel load/span and deflection tables are available
Surface Burning	Determines the surface burning characteristics of the core and panels	Underwriters Laboratories UL 723 (ASTM E84)	Core Material (5") Flame Spread 20* Smoke Developed 400 Finished Panel 2" to 5" Wall Panel Flame Spread 15* Smoke Developed 250 - 450
		Factory Mutual ASTM E84	Core Material (5") Flame Spread 25*, Smoke Developed 180
Room Fire Test	Evaluates the burning of roof and wall panels in a room configuration	Factory Mutual STD. 4880 (1994) (UBC 26-3)	Panel is rated Class 1 to 30 ft. high, 5 in. max. thickness

*The numerical flame spread rating is not intended to reflect hazards
presented by this or any other material under actual fire conditions.
