Bur-Tuff ™- Toughened Glass

Tempered glass is often called Toughened Glass which is four to five times stronger than annealed glass of the same thickness. This type of glass typically breaks into small pieces with dull edges avoiding injuries. The product complies with EN 12150 std. and ANSI Z-97.1, 1984 standard. However Tempered Glass is also mandated in other parts of the world by individual country regulations specifications.
BUR-TUFF™ has a surface stress of 70 to 122 Mpa which complies with international standards. It is manufactured by heating up the flat glass to a temperature of around 700deg. Centigrade and blowing the air onto its surface, quenching it down swiftly and uniformly. It features high degree of strength and decreases the possibility of breakage. It has excellent thermal resistance permitting it to last under a rapid temperature change of 200 deg. Centigrade. It has the same level of transparency compared with flat glass even after heat treatment process.
Applications:
Entrance doors in buildings, windows for vehicles, ships, interior fixtures, balustrade, extreme wind loads, fireplace enclosures, suitable where safety glass is required.


How we process it?




Bur-HS™ - Heat Strengthened Glass


Bur HS is approximately twice as strong as annealed glass of equal thickness. It has higher resistance to thermal loads than annealed glass and typically breaks into large pieces.

Applications:
Suitable in use of spandrel and or vision areas where added resistance to wind-load and thermal stress is required, laminated solariums, highwind loads areas, laminated skylights.





Bur- IG ™- Double Glazed Glass

Bur- IG™ is a double glass pane, with aluminium spacers placed between two panes and the entire unit is hermetically sealed with polysulfide polyurethane, or silicon sealant according to the structural requirement of glazing.
The Product offers design flexibility in colors, light transmittance, solar reflection, energy efficiency and considerable energy cost reductions compared to ordinary glasses.

Bur-Frit™ - Ceramic Frit Paint Glass


Bur-Frit™ is produced using the most sophisticated printing machine from Kera Glass, Italy. The machine applies ceramic paint on glass surface, which is dried into the glass surface going to infra red processing. The glass is then heated into the furnace. Bur-Frit™ can be produced or either Heat Strengthened or Fully Tempered glasses according to the designed specification.

Bur-Frit™ is an ideal glass processed for non-vision spandrel areas in typical curtained wall applications. It is available as monolithic (single glass position 2), insulated double glass (surface position 4) or multiple glasses for lamination or bullet proof glass application. The surface covered can be 100% when an overall specification is required or it can take form from infinite variety of decorated patterns. Such as the one displayed here:


The accuracy of our state-of-the-art silk-screening equipments also allows for double painting with the same glass surface, using different colors without any pattern overlap. Hence, Bur-Frit™ can show a different color on each surface while retaining complete silkscreen accuracy.

Bur-Frit™ silk screen high performance allows designers to create a large facade pattern which can run through the entire double-glazed-vision, or single-glazed-spandrel areas without loss or change in color uniformity.

Standard Bur-Frit™ paint color is available on request.

Bur-HSK™-Heat Soak Test

Bur-HSK™ is consists of performing superior Quality Test to avoid spontaneous breakage of tempered glass. This method reduces the incidence of NiS induced failure in tempered glass by causing the phase change to occur before glass panel is installed into the building. Bur-HSK™ is being process in our Heat Soak Test Kilns (HST) and (HST +).

Laminate Kilns made by Pujol, Italy. Bur-HSK™ offers extra security in application for structural glass and avoids cost for replacement of broken glasses in high attitude buildings exceeding tenth floor or more as well as in total glass enclosures.

Heat Soak Test Procedure

Testing is directed on glasses that would pose a danger in the event of breakage of façade, roof and balcony glazing.
Heat soak testing investigates glass which is sensitive to breakage.
The nickel sulfide (NiS) crystals might cause the glass to break, although this is improbable.
Testing: Treatment time 12 h, temperature during testing 290 +/- 10º.

Injury due to falling glass
An occupant or passer-by can be seriously injured by falling fragments. When a panel of toughened glass breaks spontaneously it produces a loud noise which can be heard from a significant distance. The reaction of people when hearing a noise above them is to look up, and this may result in fragments of glass striking a person in the face, or getting into the eyes. Bur-HSK prevents such incidents from occurring at glasses are tested prior to installation.
Size of HST Kilns - 4000 x 2500mm



Bur Proof™-Bullet Proof Glass


Bur-Proof™ relates to glasses that are resistant against the firing of specified weapons and ammunition, preventing the passage of bullets or parts of bullets through the glass into the protected side. It also protects personnel against injury from splinters of glass.

Bur-Proof™ glass is obtained by bonding several layers of the glass with Polyvinyl Butyral (PVB). The Polyvinyl Butyral (PVB) in this case is more of soft glue which absorbs most of the energy from the bulk of the glass which will stop the bullet from penetrating. The more layers and thickness, the greater the strength of the glass all over.

Bur-Lam™- Laminated Safety Glass


Bur-Lam™ contains one or more sheets of flexible, tough and transparent polyvinyl butyral film laminated between two or multiple sheets of flat glass. It is both extra-safe and shatters proof. The polyvinyl used in Bur-Lam™, is perfect- ly clear and free of any discoloration. More over it is also highly resistant to moisture and heat. The polyvinyl butyral film will not blister or in any way detract from the perfect clarity of glass sheets. All these outstanding features make Bur-Lam™ the ideal product whenever safety glass or a safety glazing material is required.

Bur-Lam™ complies with the American (ANSI) and European (EN) Standard. Bur-Lam™ glass provide strength and beauty, durability and is made by bonding two or more layers of glass, using heat and pressure, with one or more “interlayers” of PVB (Polyvinyl Butyral) film or EVA film.

The result is a tough, adaptable glazing material that offers outstanding features and design needs. Bur-Lam™ glass can be made using sheets of annealed, tempered, chemically or heat strengthened glass. It is easy to work with, replace and offers important structural performance features and benefits. Such us those mentioned below.
Features:-
Safety :
Laminated glass with PVB interlayer resists penetration from impact. When broken, the glass adheres to the resilient plastic interlayer unlike ordinary glass which may create dangerous shards.
Sound Control :
Laminated glass significantly reduces noise transmission. The viscoelastic properties of the interlayer provide a damping effect on unwanted noise.
Energy Control :
The use of laminated glass with a tinted interlayer reduces the heat gain from sunlight and helps reduce energy costs.
UV Control :
The PVB interlayer filters out UV rays which damage draperies, art and interior furnishings.
Weather/Disaster Control :
If broken in natural or manmade disaster, laminated glass will remain in its frame much longer hence averting damage to building interiors.
Security :
Laminated security glass with PVB interlayer helps from intrusion burglary, bullets explosions, without compromising light transmission and visibility.
