Sealants
Palram does not manufacture a sealant for use with Suntuf. For a list of compatible sealants,
visit http://www.palramamericas.com/sealants.
Closure Strips
Suntufs closure strips are made from wood, plastic, or foam. Foam closures are most suitable for enclosed structures where energy
efficiency is a concern.
Ventilation
With all Suntuf installations, proper ventilation is suggested to minimize heat buildup and condensation.
Depending on regional conditions this may include incorporating an open air aspect to the structures design or the installation of
power fans. For more detailed information about condensation mitigation, visit http://www.palramamericas.com/Suntuf_docs. Palram
Americas is not responsible for the failure to account for this important design aspect.
Panel Orientation
Install panels with the label side facing up toward the sky (sheet corrugations at each side will then facedown). This will ensure that the
UV protection layer is on the side facing the sun. Failure to follow this advice will result in the eventual discoloration of the panel.
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. See form 2203 - PC Care and Maintenance Instructions for more detailed information,
you can download the form at: www.palramamericas.com/Suntuf_docs.
Fasteners
Palram recommends the use of Palram/Suntuf brand EPDM washered fastener only. Palram fasteners for Suntuf panels are tested and
approved to be compatible with polycarbonate, whereas other brands may not be. Incompatible washers can result in panel failure that
is not covered by warranty. Contact Palram for information about availability of optional larger washers if local building codes prescribe
their use, or if installation is in high wind area.
Pre-drill all fastener holes with a ¼" drill bit for Woodtite and Metaltite fasteners to accommodate for the thermal movement of the
panel. Over-drill by an extra 1/16" for other fastener diameters. Failure to accommodate for thermal movement will cause buckling of
the sheet.
Use 2" fasteners for all roof applications. 1" fasteners are adequate for vertical applications (i.e., side walls, end walls, and partitions).
DO NOT Over-tighten fasteners causing the rubber washer to compress. Tighten all fasteners
until they are ”snug. If the neoprene washer becomes deformed, the fastener is too tight.
Drive fasteners perpendicular to the Suntuf face (see illustration given to the right).Tighten
moderately by hand or with an adjustable torque power screwdriver. NEVER use an impact
wrench / driver for fastening Suntuf.
IMPORTANT NOTE: The washers / gaskets chosen for use with Suntuf panels were selected after careful checks and tests. Shaped
gaskets seal the fasteners’ holes and heads well without excessive pressure on the Suntuf panel, allowing for limited thermal expansion.
Recommended washer / gasket compatibility with polycarbonate is assured by Palram Americas.
