e) Other PALSUN thermoforming procedure use various
methods, sometimes integrated with each other, based
on heating and forming in molds under mechanical
pressure, compressed air or suction (vacuum-forming).
They enable creating 3 dimensional glazing panels,
much tougher and rigid than their basic thickness may
suggest. It enables preparation of skylighting domes,
canopies, roof or wall glazing panels of thinner material
at lower cost
d. Basic Guidelines for Correct Design & Application of PALSUN Glazing:
1) General Comments:
a) PALSUN at all variations is an excellent glazing material for different applications of glazing and light-
transmitting cladding. Careful design and implementation according to Manufacturer directives,
recommendations and installation instructions would lead to many years of satisfying service.
Disregard of Manufacturer design directives & recommendations and careless or indifferent follow-up of
the installation instructions may lead to faulty function, failings & damages. Breakage and eventual
failure, and a substantial reduction in glazing endurance.
b) PALRAM Tech-Support department will supply the designers with state-of-the art professional
assistance and consultation during all stages of design and preparation of necessary specifications for
tenders, and further direct & instruct said designers, project managers and supervisors how to oversee
the main & sub-contractor’s form and quality of execution.
2) Basics for Design:
a) PALSUN Thickness: Sheet thickness would be determined according to glazing design, supporting
frame, glazing spans and local engineering codes for wind/snow loads, and/or from special man-made
reasons (crowd swarming, vandalism or violence), as appears elsewhere in this guide.
b) Prevention of Mechanical damage: Regular PALSUN is softer than glass, even if much more impact
resistant. PALSUN surface might be damaged from hits, mechanical strikes, abrasive and polishing
substances, cleaning tools & accessories, even those which do not chemically attack the polycarbonate
glazing.
We Recommend:
• PALGARD: Whenever such conditions are anticipated, and the design allows it, use PALGARD sheet
for better mechanical surface resistance.
• Obstacles for Vandals: When possible, prepare in the design a barrier or obstacle creating a gap
wide enough to prevent or interfere with a direct damaging contact between a probable assailant
and the glazing.
• Maintenance & Cleaning: Prepare in advance clear and easily recognizable signs with proper
instructions for the recommended Maintenance & Cleaning.
