-
Clean window frame. Remove old putty or broken
glass, if necessary.
-
Measure sheet edge engagement area (± 0.75 inch)
and internal window frame dimensions, i.e. the space into which
the Polycarbonate sheet will be fitted.
-
Calculate sheet size, allowing clearance for thermal
expansion (0.118 inch per linear 39 inches).
-
Select right polycarbonate sheet type, which fulfills loading requirements,
U-value, etc.
-
Clamp the polycarbonate sheet to a support table to avoid
vibration and rough cutting.
-
Cut the sheet to required size, using a standard
electric circular or jig saw using a plywood blade (minimum 10
teeth per inch) or blade designed to cut plastics.
-
Blow out the saw dust contaminated channels with
clean compressed air.
-
Remove any sharp edges and irregularities from the
sheet.
-
Peel back approximately 2 inches of masking film
from all 4 edges of the cut sheet on both sides.
-
Select appropriate sealing tape by an accurate consideration
of glazing application.
-
Seal the top and the bottom sheet channels with
impermeable and/or venting tape
Please refer to the processing instructions provided by the sealing
tape supplier.
-
In case of venting tape, and to allow condensed
water drainage, apply an aluminum closure profile with drainage
possibilities or apply some single sided self adhesive glazing tape
as distance holder between the venting holes.
-
For wet glazing apply single sided self adhesive
glazing tape or rubber profile to both window frame and bead.
-
For dry glazing, snap-fit neoprene rubber gaskets
in place in support profile as well as in clamping cover profile.
-
Insert the sheet into the window
frame.
-
Multiwall PC sheet should always be installed
with the ribs running vertically and the UV protected sheet surface
should always face outwards.
-
Fix window bead or clamping cover profile in place.
-
For wet glazing apply an appropriate silicone
sealing compound, sealants between sheet and window
frame/bead.
-
Remove all masking film immediately after installation.
-
Clean window carefully with warm soapy water and
soft cellulose sponge or woolen cloth.
-
Do not use plasticized PVC or incompatible rubber
sealing tapes or gaskets.
-
Do not use amine, Benzamide or Methoxy based sealants.
-
Do not use abrasive or highly alkaline cleaners.
-
Never scrape PC sheet sheet with squeegees,
razor blades or other sharp instruments.
-
Do not walk on PC, acrylic or glass sheet at any time.
-
Do not install sheet with damaged tape.
-
Do not clean sheet in hot sun or at elevated
temperatures.
-
Benzene, gasoline, acetone, carbon tetrachloride
or butyl cellosove should never be used on Plastic sheet.
-
Some systems (like the Twinfix®
Multilink® Glazing System) do not require a gasket when in use
with Multiwall PC Sheet. This system is compatible with every
sheet manufacturer worldwide.
