Insulated EWP Wall Panel

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 1/2", 3", 4" and 5".

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 � Dura-20 (silicone polyester)
Royal K-70 (Kynar 500/Hylar 5000)

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.

Test Data

Test	Purpose	Procedure	Results
