HIGHLY
FLEXIBLE
Unlike
glass and acrylic, multi-wall Polycarbonate can be readily cold
formed to many bending radii and can be fabricated on site to precise
dimensions. To avoid over tensioning of the sheet, the minimum bending
radius is 150 times the thickness of the panel.
VIRTUALLY
UNBREAKABLE
Able
to stand extreme abuse, its impact strength is 200 times greater than
glass and 10 times greater than acrylic.
SAVES
ENERGY
multi-wall Polycarbonate sheets offer high thermal resistance, promoting
energy savings of up to 60% over traditional glazing. multi-wall
Polycarbonate sheet is manufactured using state-of-the-art co-extrusion
technology combining color, U.V. resistance and durability.
WARRANTY
multi-wall Polycarbonate is backed by a 10 year limited warranty on
light transmission and breakage caused by hail.
|
CO-EXTRUSION
Multi-wall Polycarbonate is a high performance polycarbonate sheet.
During manufacture a layer of U.V. absorber is co-extruded onto the
surface of the sheet, forming a barrier against U.V. radiation. This
gives Multi-wall exceptional resistance to aging without
affecting the mechanical properties and impact strength.
|
FLAMMABILITY
Multi-wall Polycarbonate sheet is classified as Self-Extinguishing.
Compared with other thermoplastic products used in the building
industry, it will not support flames. Above all, it does not give off
toxic gases.
IMPACT
RESISTANCE
Among
the thermostatic products used in the building industry, multi-wall
Polycarbonate has the highest impact resistance. You can be assured that
from transport to installation, will maintain its durability.
Even when exposed to elevated temperatures over a long period of time,
it will maintain its structural integrity. On-site, it will not crack or
splinter, assuring you a high degree of safety.
multi-wall Polycarbonate is so strong it withstands the impact of 16
lbs. dropped 25 feet on an 8 mm panel with no breakage. It will maintain
its impact strength over a wide temperature range from - 40F to 250F.
|
LOAD
RESISTANCE
A
wide range of applications is available with thermoglazing. In
order to evaluate the loads for each application, a reference diagram
has been prepared for sheets supported on 4 sides with purlin spacing.
This diagram is valid only when the following conditions are followed:
Correct
calculation of expansion in order to provide for the necessary allowance
in the framing. The thermal expansion coefficient is 0.0000375 in/in °F.

Install the sheets with the ribs running
vertically and following bending specifications in bent applications.
Washers and sealing materials must be compatible with polycarbonate. |
|
PRACTICAL
ADVICE
is supplied with a protective PE film on both sides which should be kept
on until work is completed. The U.V. protected side is to be faced
towards the sun and is marked with a white printed film or light blue
film and a sticker saying multiwall polycarbonate sheet.
crates or sheets should be stocked in an area not exposed to
the sun which could make the removal of protective film difficult.
Stiff fixing by means of adhesive or putty is to be avoided. Top and bottom
ends of a sheet must always be sealed by means of the proper
polycarbonate profiles or an adhesive aluminum tape to prevent dust or
dirt penetrating the inside of the ribs and will help reduce
condensation. |
