Locations where fallout protection is required |
 |
 |
When the wired glass is cut, the exposed metal wires
are bent and hairline cracks can occur along the glass edges, decreasing
strength.
 |
 |
Exposed metal wires along the edges of the glass can
be rusted by rainwater or dew condensation. Wired glass can be damaged
due to the spread of rust. |
 |
Maintain an ample distance between the surface of the
glass and thick curtains, shades, lockers, etc. |
 |
The glass surface should not be painted or coated with
paper. |
 |
The glass surface should not be exposed to direct currents
of air from air-conditioning units. |
 |
Calculate and carefully consider thermal values to avoid
thermal cracking when a shading or decorative film is put on the glass
surface. |
 |
Use a flame-resistant silicone sealing compound when
polished wired glass are used as fire door. |
 |
The building designers are responsible
for incorporating specific characteristics of wired glass when determining
the applicable locations and area for the glass.
 |
 |
The primary feature of polished wired glass (diamond
and cross mesh) is its fire resistance. These glass products are not
safety glazing materials, and should not be used as such or in locations
where human impact is possible or where safety glazing is required.
However, there is some use of polished wired glass if building regulations
require or permit it for such application.
|
 |
 |
CENTRAL GLASS's polished wired glass (diamond and cross
mesh) are listed by Underwriters Laboratories, Inc. of the US as fire
resistance rated glazing material 11G4, after tested in accordance
with UL9, UL10B and UL10C.
In Japan, it conforms to the fire performance test specified by the
Japanese Industrial Standard (JIS R 3204) and the Building Code of
Japan.
