 |
 | Fire resistance |
|
The glass is formulated for fire protection performance. In case
of fire, the glass cracks but broken pieces tend to remain in the
sashes rather than fall out, restricting the spread of flame and smoke.
|
 | Fallout resistance |
|
When the glass is broken by the impact, fragments tend to remain
in the sashes rather than fall out. The chance of shattering is therefore
less than that of float glass.
 |
 | Cost effectiveness |
|
Wired glass is one of the most cost-effective glazing materials
when fire protection is required in windows, doors and partitions.
 |
 |
 |
Exteriors and interiors of general constructions
 |
 |
Doors and windows of buildings where fire protection
is required |
 |
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 edges, decreasing
strength.
 |
 |
Exposed metal wires along the edges of the glass can
be rusted by rainwater or condensation. Wired glass can be damaged
as rust spreads. |
 |
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. |
 |
 |
The building designer is responsible for incorporating
specific characteristics of wired glass when determining the applicable
locations and area for the glass.
 |
 |
Follow the building codes and glazing instructions and
precautions stated in this catalog. |
 |
To prevent accidental falls, do not step on the glass
unit when installed in a skylight. |
 |
 |
Use a superior elastic sealing compound (polysulfide
or silicone).
 |
 |
Three water drain holes (5 mm in diameter) must be provided
at the sash bottom for draining rainwater or condensation quickly. |
 |
Protect edges of the wired glass from corrosion with
butyl tape or corrosion-protecting paints in accordance with the standard
glazing diagrams. |
 |
Cut wired glass units carefully. |
 |
Use a sander of #120 mesh or above to smooth and correct
cut edges. |
 |
Use polyethylene foam or chloroprene rubber as a backup
material. |
 |
| Provide setting blocks of chloroprene rubber (90 |
° |
hardness) |
|
| at two places along the bottom edge. |
