Application Instructions

In the event Cedar Valley published application instructions conflict or contradict local building codes, please call the factory for clarification. If no local codes exist, refer to the 2003 I.C.C. residential building codes for guidelines.


FIRST DETERMINE CORNER TYPE With flush-mounting corners, install corner first. Double wrap corners with building paper. Use two nails per corner side, 1.25" down from tip. Install the seperate corner units provided in the A,B,C,D pattern stamped on the back (2 of each per bundle). Caulk corner edges well. Trim panel end and push against caulked corner edge. Nail panel as per instructions. (No starter course is needed.) With add-on corners, install all panels first, positioning so that panel ends are flush with corner without overlap. (Panel ends do not need to be trimmed.) Nail panel as per instructions. Apply corners using two nails per corner side, 1” above the exposure line of the panel being installed. Add-on corners require one course starter pieces or shims, using either prefabricated units supplied or site-made from individual shingles. Apply appropriate building paper under panels as per building code requirements. Double wrap corners a minimum 9-inches each side.

BLIND NAILING INSTRUCTIONS
See published application instructions for standard nailing details

See 1 Course Blind Nail Hurricane instructions for hurricane nailing patterns.

PANEL APPLICATION
Plan panel layout from lowest building corner after determining corner type to be used. Panels may be applied directly to studs 16" or 24" O.C., or to nailable shear sheathing, over approved building paper in accordance with building codes. Panels must span at least two stud spacings and vertical end joints should be staggered to join on stud. Horizontal scribed guidelines enable proper alignment of succeeding panels without measuring or leveling every panel. NOTE: Panels do not meet shear requirements.

FLUSH CORNERS
Flush-mounting corner units are prefabricated of Western Red Cedar tapered shingles stapled and glued to 11/32" exterior plywood sheathing in the Boston Weave construction. They are manufactured and supplied in 4 different widths so, when alternated with each panel row the vertical corner line is eliminated.

INSIDE CORNERS
Nail a 1-1/2" x 1-1/2" wood strip into the inside corner and caulk liberally where the panels will butt against it. Trim panel ends square and force tightly against the strip, nailing according to instructions.

FIRE RESISTANCE
A permanent Class A flame spread treatment is available on any panel Cedar Valley makes. One-hour fire rated wall construction can be achieved by using gypsum wallboard on both sides of a 2"x4" studwall 16" O.C. See local building inspector for approval in you area.
