HANDLING & STORAGE:
Stack short sheets on top of
longer ones. Store sheets in a
cool and dry place out of direct
sunlight. To prevent solar heat
buildup, avoid covering the stack
of sheets with a dark tarp or other
heat absorbing material.
THIS SIDE UP:
The UV-protected side of the
sheet is covered with printed lm
and must face towards the sun.
CLEANING:
Normal dirt and dust accumula-
tion is washed o by periodical
rains. Regular rinsing of the
sheets with clean lukewarm
water is sucient in dry areas.
Mild household detergent may
be used with a soft rag. Never use
aggressive or abrasive cleaning
agents or glass window cleaners;
they can chemically attack the
sheets.
REMOVING FILM:
Remove approximately 2 inches
of lm from sheet edges before
installing. Remove all lm
immediately after sheet installa-
tion is complete.
DRILLING:
Use only new or sharply ground
steel or carbide tipped drills. The
diameter of drilled holes must be
1.5 times larger than the screw’s
diameter to allow for thermal
expansion, providing enough
space to allow for seasonal
temperature uctuation.
CUTTING:
Masking lm should remain on the
sheet to prevent scratching. Utility
knives can be used to cut. Sheets
should be clamped for hand saw
cutting to prevent vibration.
Sheets can be cut with a circular
saw using a
ne-tooth (10 to 12 TPI)
blade
. Remove dust from the
surface with compressed air or a
vacuum.
INSTALLATION:
Use H-Channel to connect two
sheets. (Wide side of prole to the
inside.) Fasten supports at all four
corners 1-1/2” from edges. At purlin
supports, fasten 6” from edge.
When cold bending, min. radius is
41” for 6mm / 110“ for 16mm. Bend
sheet longitudinally, never across
sheet width. Flutes must run on at
least a 2/12 pitch. Maximum purlin
spacing is 24” 6mm / 36” 16mm. Do
not walk on sheets at any time.
END CLOSURE:
Structured polycarbonate sheets
must always be installed with ribs
positioned vertically. Seal ends
with anti-dust tape and a U
channel. Drill weep holes every 12”
with a 1/8” drill bit to allow conden-
sation to drain out the bottom of
the U channel. (Wide side of prole
to the inside.)
SILICONE SEALANTS:
Use silicone as a sealant. Other
caulking or sealants may attack
sheets. Check silicone product label
to ensure compatibility. 100%
silicone is compatible with polycar-
bonate.
