Pyroclear

This is a high strength, safe and fire preventive sheet glass without a mesh wire.

Pyroclear has no mesh wire and is a heat-resistant glass complies with the Class B and Class A of the Fire Prevention Standards. It is heat tempered to a sheet glass that is processed by the floating method.
Its clarity is as same as that of a sheet glass processed by the floating

method, and in addition, it provides safeness equivalent to that of tempered glass.
Its maximum available size in Japan is 2400 x 1800 millimeters.
Its tones of colors are available in a total of as many as 25 variations.
It provides you safeness, rich light and spacious feeling.

Pyroclear a Conventional Wired Glass

Fireproof glass.
Conventionally, wired glass was used for the purpose of fire prevention.
Wired glass is often misunderstood by people as its appearance. People think that it may be used for crime prevention.
Since molten glass does not drop apart by means of flame. It prevents flame from spreading to in and out of a building.

Pyrolcear is a fire preventive glass:
Its edges are specially processed and heat tempered. It complies to the Fire Prevention Test Standards Notice issued by the Ministry of Construction. It is widely used for the Class B Fire Prevention Door as well as for the Class A Fire Prevention Door.

Heat Resistant Glass:
The Class B Fire Prevention Door Glass
It is approved as the main composition in the General Approval No. 2 covering "The Class B Fire Prevention Door Made of Aluminum".
The Class A Fire Prevention Door Glass:
Conventional Class A doors and shutters were generally made of steel. As we have achieved a specific approval for Pyroclear, it makes you easily adopt this type pf glass.

WIRE LESS
Since Pyroclear is a fire prevention glass processed against the sheet glass made by the floating process which is commonly used for buildings. It provides you very clear visibility as we as quite natural tones of colors.

Pyroclear has the same tone of color that of the commonly available sheet glass processed by the floating method. It is therefore easy for you to tune its tone of color to adjacent glasses.
(However, reflected images appears as same as that of commonly available tempered glass.)

Pyroclear Nomal Flat Glass

High Strength and Safety Glass

Its strength is six(6) times than that of the floating processed glass in the same thickness as this glass is super tempered, and as much as twice stronger than the commonly available tempered glass.
It is not breakable by means of heat.
Pyroclear
This is a generic safety glass. Even if it is broken, it becomes very small particles, therefore, it is safe not only in case of fire but collision by humans as well as earth quake, too.

Classification of Glass Products (Applicable to tempered and safety glasses.)

Conforming to Tempered Glass per JIS R3206 Group
Wind Pressure Design: Corresponds to the coefficient 3.0 of the classification per the notice No. 109 by the Ministry of Construction.
Guidance to Safety Design: Corresponds to the notice of "Safety Design Guidance of Openings" by the Ministry of Construction in May 1986.

Pryoclear has four(4) types. Such as transparent, heat wave absorption, heat wave reflection, and high performance heat wave reflection types in 25 color variations.

Transparent Type (Clear)……………………………….. ………….One(1) color.
This is a Pyroclear glass using generic sheet glass processed by the floating method.

Heat Wave Absorption Type (blue, gray, bronze and green)…Four(4) colors.
This is a Pyroclear glass using the heat wave absorption type sheet glass.

Heat Wave Reflection Type (Ref-light)…………………………….Three(3) colors.
This is a Pyroclear glass using the heat wave reflection type glass.

High Performance Heat Wave Reflection Type (Ref-shine) ….17 colors.
A spattering process is applied to the transparent type Pyroclear.

Available Sizes:

Pyroclear's maximum size is as large as 2400 by 1800 millimeters(8 mm thick).
An extraordinary process is applied to edges of Pyroclear, and its entire circumference is covered with a metal tape in order to protect edges.
Do not detach the tape and install the glass with the metal tape.

Matters Require Attention in the Course of Design, Installation and Use:
How to acquire an approval of fire prevention door:
An approval for any fire prevention door is not solely given to the glass, but the approval can be acquired for the combination of glass and sash and/or glass and its frame. We wish you to confirm prior to your installation whether such approval is being given or not to the door which you intend to use, and check its specifications.
In case the door is to be approved by the general rule:
Install a glass sheet to an approved aluminum sash applying the standard fire prevention manner. Note that the glass cannot be shoved to the corner of the opening.

In case the door is to be approved individually:
An approval against any fire prevention door is not solely given to the glass, but the approval can be acquired for the combination of glass and sash and/or glass and its frame. We wish you to confirm prior to your installation whether such approval is being given or not to the door. If you wish to get a new approval, please contact us prior to your application for the approval.

Use:
For a roof as well as a top light(sky light) that require the 30 minutes fireproof durability, only wired glass can be used for this purpose presently.
Furthermore, other than fire prevention use, we suggest you to refrain from using the glass where a heat more than 200 degrees C is repeatedly given such as a stove.

Typical Characteristic
It has similar characteristic of generic tempered glass.
It tends to suddenly breaks apart without any external force due to growth of deep wounds on the surface of glass.
(In order to prevent breakage from wounds caused by impurities, Pyroclear is treated with soaking process.)
Due to its specific characteristic, it entirely crushes and particles fall down in the worst case of crush. We suggest you to get in touch with us or any of our branch office, if you intend to use this type of glass at a falling height in excess of 16 meters (hanging on a ceiling) and seven(7) meters high (except heat wave absorption type and ceiling installation).

Pyroclear has twice as much as strength compared to that of generic tempered glass, however, we suggest you to use Pyroclear as in the same manner applied for generic tempered glass as far as its wind pressure calculation is concerned.

If you wish to attach greater importance to reflected images, use an eight(8) millimeter thick Pyroclear. As Pyroclear is heat treated, reflected image is somewhat disordered when compared to those sheet glasses which are not heat treated.

Carrying out a construction:
If the glass edges are hurt, prescribed fire prevention may not be guaranteed. In order to protect edges, Pyroclear's entire circumference is wrapped with a metal tape. Pay your utmost attention when you carry it and during installation work. Do not detach the tape and have it remain on the glass.

Processing the Pyroclear
Pyroclear is only available in the form of flat sheet. It is impossible for you to drill a hole, cut its edge and bend. Please order from us showing a size which you are desirous to use.
If case you wish to use Pyroclear in the form of lamination or a specific shape is needed, please call on us.
