sheet Glazing Guidelines
Wet Glazing
Do’s
• Clean the window frame. Remove old putty or broken
glass, if necessary.
• Measure the sheet edge engagement area (± 20 mm)
and internal window frame dimensions, i.e. the space
into which the Lexan Thermoclear sheet will be tted.
• Calculate the sheet size, allowing clearance for
thermal expansion (3 mm per linear metre).
• Select the right thickness to full loading
requirements, U-value, etc.
• Clamp the Lexan Thermoclear sheet to a support
table to avoid vibration and rough cutting.
• Cut the sheet to the required size, using a standard
electric circular or jig saw.
• Blow away saw dust build-up in the channels with dry
compressed air.
• Remove any sharp edges and irregularities from
the sheet.
• Peel back approximately 50 mm of the masking lm
from all edges of the cut sheet on both sides.
• Carefully select the sealing tape appropriate to the
glazing application.
• Seal the top and the bottom sheet channels with
impermeable and/or venting tape, f.i. Multifoil G3600
/ AD 3400 / AD4500.
Please refer to the processing instructions provided
by the sealing tape supplier.
• In case of venting tape, and to allow condensation
drainage, apply an alu closure prole 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 prole to both window frame
and bead.
• For dry glazing, snap-t compatible neoprene rubber
gaskets in place in the support prole as well as in the
clamping cover prole.
• Insert the Lexan Thermoclear sheet into the window
frame.
• Lexan Thermoclear sheet must always be installed
with the ribs running vertically. The UV protected
surface should always face outwards.
• Fix the window bead or the clamping cover prole
in place.
• For wet glazing apply an approved silicone sealing
compound, such as Silglaze/Silpruf between the
sheet and the window frame/bead.
• Remove all masking lm immediately after
installation.
• Clean the window carefully with warm soapy water
and with a soft cellulose sponge or woollen cloth.
Dry Glazing
Don’ts
• Do not use plasticised soft 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 Lexan Thermoclear sheet with
squeegees, razor blades or other sharp instruments.
• Do not walk on Lexan Thermoclear sheet at any time.
• Do not install Lexan Thermoclear sheet with damaged
tapes.
• Do not clean Lexan Thermoclear sheet in hot sun or
at elevated temperatures.
• Benzene, gasoline, acetone, carbon tetrachloride
or butyl cellosove should never be used on Lexan
Thermoclear sheet.
