Installation Instructions

Installation

Before starting installation, check that the wall surface is straight and if needed install furring

strips. It is recommended to use vapor barrier and consult local building code for vapor barrier

requirements.

Installation of vinyl I span wall panels can be parallel to ceiling joists, roof trusses and wall

studs. If additional support is needed, use 1” x 4” or 2” x 4”. Always check local building code

for maximum spacing. We would recommend spacing of 24” as a minimum requirement if

attached support is perpendicular to the structural members.

All trims used for windows and/or doors, as well as other openings should be attached to a

furring strips.

The ﬁrst fastener should be nailed at the center of a panel and continue to ends. After fastening

check interlock and ease of movement.

If I span wall panels are used for wall and ceiling, make sure that wall panels are installed

before ceiling panels.

Start installation along the bottom of a wall with Base trim or J-Channels*. After that install

corner trim and appropriate trim on ceiling (corner trim or J-channel) and start with panel

installation following Basic installation instructions.

• If J-channel is used make sure to drill ¼” holes along bottom 16” on center for drainage.
