The Awnings can be made with transparent plasticsBy Carlos Mello
The Awning crystal, known as " transparent " curtain, it is indicated for closing of atmospheres that need to protect against
cold,
wind and
moderate rain, without losing
visibility, because their main characteristic is
transparency.
The awning crystal doesn't have
internal plot, therefore their mechanics qualities are limited and inferior to
one of
canvas of PVC. If be picked up wet and stay closed for some time,
water doesn't evaporate and " penetrates " in
crystal, leaving it with a characteristic " milk ".
This problem will disappears completely after some time open " taking sun ".
The manufacturing of
awning crystal is in two ways:
Horizontal welds:
Less numbers of welds, however can have shrink in
width after some weeks, because
product doesn't possess
internal plot. Due to
static energy generated by
attrition in
rolling up and
extremely flat surface,
awning Crystal " glues " if it is coiled for several hours.
