Installation Guide

Installation Tools
Lightweight and easy to handle, multiwall sheets can be fabricated on site and require no special tools to
install. Common tools needed include: table or circular saw with a ne-tooth blade, clamps, drill with a ¼”
bit, tape measure, safety glasses, utility knife, straight edge, sawhorses, and a ladder.
Fasteners
A key component of most building projects, it is important to make sure you choose the correct
fastener for your specic application. When the wrong fastener is used, both the fastener and the
sheet can fail.
The chart below is a recommended fastener hardware guide for polycarbonate applications.
SCREW LENGTH TIP/HEAD MATERIAL THICKNESS STRUCTURE WASHER
#10 2” Sharp Tip 6-16mm Wood .75”
#10 2.5” Sharp Tip 25mm Wood .75”
#12 2” Hex Head 6-16mm Treated Wood .75”
#12 2.5” Hex Head 25mm Treated Wood .75”
#12 1.5” Self-Drill/Self-Tap 6-16mm Steel .75”
#12 2” Self-Drill/Self-Tap 25mm Steel .75”
#12 1.5” Self-Drill/Self-Tap 6-16mm Aluminum .75”
#12 2” Self-Drill/Self-Tap 25mm Aluminum .75”
Fasteners should penetrate the structure by at least one (1) inch.
Install Components
Before beginning your project, conrm you have all the necessary install components. Most projects will
require one or more of the following:
There are many factors to consider when selecting a fastener including length, color, sheet thickness,
the type of structure, and the environmental conditions. For help with choosing the right fastener for
your project, call 800.421.0102 to speak to a knowledgeable Polymershapes associate.
Tape
Use sealing tape on both ends of a multiwall sheet to prevent dust, bugs,
and excess moisture from entering the utes.
• A solid aluminum foil-coated tape with an all-weather adhesive may
be used to seal o󰀨 the top of a multiwall sheet.
• Vent tape made of a strong non-woven material is recommended
to seal o󰀨 the bottom and/or top of the sheet. Vent tape provides
moisture-control and helps to maintain sheet clarity.
Note: Tape should not be exposed to the elements; cover it with ashing, ridgecap, or U-Proles.
