AGC WIRED GLASS
Fire Resistant
When wired glass is made, lengths of wire or wire mesh are embedded in the glass during the manufacturing process.
AGC Wired glass containing wire mesh is manufactured primarily for its fire-prevention and shatter-resistant characteristics,
while wired glass made with single strands of wire is primarily intended as psychological burglar proofing and shatter prevention measure.
- Even when wired glass is broken, the wire embedded in the glass holds the broken fragments in the place and prevents glass from falling out and holes from appearing in the window.
- Even when wired glass is broken by fire, it still acts as a barrier to the entry of flames and sparks, effectively preventing the spread of flames and fire through the opening.
- According to the Japanese building Standards Act, openings on an external wall could spread fire. So, there is a need to use fire prevention doors. Wired glass, when installed in a sash that meets the requirements, can be used in a fire prevention door.
Feature, Benefits :
Fire Resistance
Because of the best quality of wired glass structure, it can prevent a fire more than 1 hour even if in a high temperature at 925 degree celsius.

Prevention
Even when wired glass is broken, the wire embedded in the glass holds the broken fragments in place and prevents glass from falling out and holes from appearing in the window. Moreover, it still acts as a barrier to the entry of flames and sparks, effectively preventing the spread of flames and fire through the opening.

Resistance to Shattering
Because wired glass is unlikely to drop shards of glass, even when broken as a result of a projectile impact or earthquake, it is less likely than ordinary flat glass to cause injury or damage due glass fragments.

Resistance to Burglary
Wired glass is more difficult to penetrate than ordinary flat glass and tends to act as a psychological barrier to illegal entry.
Applications :
In opening that could cause the spread of fire, as stipulated in the Building Standards Act.
In location such as fire exit, roof, skylight and veranda where any glass breakage could give rise to the risk of falling glass.
In fire-prevention separations and smoke-retardant hanging partitions.

NOTE :

Warning & caution

 

Precautions

 

- Because the wires in the glass are torn off when wired glass is cut, exposed edges can easily cause injury and the edge strength is approximately half that of ordinary flat glass (100 kgf/sq.cm) Consequently, bear in mind that wired glass is more susceptible to thermal breakage than float glass.

 

- Though the surface of the wire used in wired glass is specially treated to prevent rusting, cut edges are not treated and can rust depending on the circumstances (particularly the presence of moisture.) Severe rusting can cause the wires to swell, causing cracks in the edge of the glass and lowering the edge strength of the glass, which can in turn cause thermal breakage.

 

 

Notes on Use and Maintenance

 

- Radiant heat from heating appliance, water heater and cooking stove can cause thermal breakage. Take care that such appliance do not face directly to the glass.

 

- Thick curtain or furniture placed directly against the glass can cause heat to accumulate and result in thermal breakage. Take care to avoid this.

 

Notes on Design and Installation

 

- Install this product using the glazing procedures for wired glass.

 

- Though wired glass can be difficult to cut, make any cuts as cleanly as possible.

 

- For edge treatments such as polishing, use a sander with 120-drade abrasive or finer

 

- If wired glass is used in location such as an atrium or pool where it is exposed to severe

 

environmental conditions or in location where maintenance is difficult, thorough measures

 

must be taken to prevent rust breakage.

 

Glazing and Installing Wired Glass

 

- Use only sashes provided with water drainage features as stipulated standard.

 

- Use a high-quality elastic sealant (but not acetic acid-based sealants) to ensure that the glass

 

edges are completely waterproofed.

 

- Use polyethylene foam or chloroprene rubber as the backup material.

 

- In 2 locations along the bottom groove of the frame, use setting blocks of high-quality PVC

 

resin or chloroprene rubber with a hardness of at least 90 degree

 

- PVC bead is not suitable for glazing wired glass as it does not ensure that the glass edges

 

are fully waterproofed, If the use of PVC bead is unavoidable, one of the waterproofing treatments described below must be used on the glass edges to prevent rust breakage.

 

   - Application of rust-preventive paint.

 

   - Application of rust-preventive oil (ex.Mobil's Metal Guard #831)

 

   - Application of butyl rubber tape
