Before You Begin
Make sure the color of all panels match. Be sure panel and horizontal closure support strip t
together... SUNTUF polycarbonate panels are square. Snow, wind and weather loads should be
considered when designing the slope degree of your structure (Min. 1½" in 12"). Before installation, check
local building codes for relevant specications and recommendations. Follow local codes at
all times.
TRANSPORTATION, handling and storage: Do not transport, leave or store panels in direct sun be-
fore or during installation. For outdoor storage, cover securely with a white opaque polyethylene sheet
to avoid solar heat gain between the panels. Sunlight is magnied when passing through uncovered
sheets, increasing the temperature of the sheets, which leads to degradation and distortion. Penetra
-
tion of water between the sheets in storage will accentuate this heat gain. Therefore, it is recommend-
ed to store the panels indoors. Panels will withstand heat when properly installed and ventilated. Store
the panels stacked evenly on a horizontal flat surface with longer lengths on the bottom. Do not stack
other items on top of panels. If panels are not stacked directly on floor, be sure to support evenly.

INSTALLATION NOTES:
Install panels with the label side facing toward the sky (sheet corrugations at each end
will face down).
To Cut Panels: Use either a circular saw with a plywood blade reversed, a utility knife and a
straight edge, or a pair of snips. Support the sheets to avoid vibration and cut at slow speed.
Up to ve panels can be cut with a circular saw.
Pitch: This is the amount of height in inches the rafter rises over a 12" run. Minimum slope is
1½" in 12" (see gure D). Never install panels on at roofs.
Purlins/Cross Supports: Cross supports (purlins) must be no more than 36" apart for SUNTUF.
Cross supports should be at least 2" x 2" lumber.
Sealants: For SUNTUF sheets, it is recommended you use any sealant/adhesive that is
recommended for polycarbonate materials. (See gure H).
Closure Strips: Made from either plastic, wood or foam, corrugated horizontal closure strips
are required. They are used horizontally under the panels as fastener supports. Plastic corrugated
horizontal closure strips are recommended. Plastic vertical closure strips are recommended for
nishing the outside edges.
Ventilation: Ventilation is recommended to avoid condensation and heat build up.
Fasteners: Use Palram brand EPDM Washered fasteners only. NEVER use nails Predrill
all fastener holes with a 1/4" drill bit to accommodate for the thermal
movement of the panel. Failure to accommodate thermal movement will cause
buckling of the sheet. Attach fasteners on the crown of every other rib in the
horizontal direction. In high wind areas, fasten on the crown of every rib. Use 2"
fasteners for all roof applications. DO NOT overtighten fasteners causing the
rubber washer to compress.
TIP: Tighten all fasteners until they are “snug”. If the EPDM
washer becomes deformed, the fastener is too tight!
Care and Maintenance: Avoid contact with chemicals, paints, adhesives or other
synthetic materials that are incompatible with polycarbonate. Never use glass
cleaners with ammonia, or ammonia based products. Clean with lukewarm soapy
solution using a soft cloth or sponge. Do not use abrasive brushes as these will mark
the surface. For full care and maintenance info, visit Suntuf.com
