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-FritT can be either Heat Strengthened or Fully Tempered glasses according to the designed specification.
Bur-Frit™ is an ideal glass processed for nonvision 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 resistant 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-FritT 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.
Maximum Production Size : 2200 x 3600mm
Bur-HSK™iconsists 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-HSKT is procesed in our Heat Soak Test Kilns (HST) manufactured by Pujol, Spain. Bur- HSKT 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.
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.
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 as glasses are tested prior to installation.
Size of HST Kilns - 4000 x 2500mm.
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 shatter resistant. The polyvinyl used in Bur-LamT, is perfectly 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-LamT complies with the American (ANSI) and European (EN) Standard. Bur-LamT glass provide strength, beauty and durability. It 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-LamT glass can be made using sheets of annealed, tempered, chemically or heat strengthened glass. It is easy to replace, work with and offers important structural performance features and benefits, such us those mentioned below.
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.
The use of laminated glass with a tinted interlayer reduces the heat gain from sunlight and helps reduce energy costs.
The PVB interlayer filters out UV rays which damage draperies, art and interior furnishings.
If broken in natural or manmade disaster, laminated glass will remain in its frame much longer hence averting damage to building interiors.
Laminated security glass with PVB interlayer helps from intrusion burglary, bullet penetration and explosions without compromising light transmission and visibility.

Fire Resistant Glass is a specialist glass that has been proven to provide a period protection against fire. It is also known as Fire Rated Glass.
The degree of protection offered depends on the type of fire resistant glass used and it acts as a barrier to help prevent the spread of flames and smoke in the event of a fire. Certain types of fire resistant glass will also provide a degree of protection (insulation) against the heat of a fire. The use of fire resistant glass is therefore an important component in building safety and Building Regulations specify where it must be used.
The benefits of the fire resistant glass is the ability to compartmentalise and restrict fire damage. It is used for areas which are designated to provide a safe exit/access route in the event of a fire and to help prevent the spread of fire throughout a building which reducing structural damage.
Fire resistant glass has many uses, comes in many different forms and is highly flexible. It comes as Polished, Wired or Laminated/ Toughened. Certain fire resistance glass can therefore be used where both Impact Safety Rating and fire resistance are needed.
It is also comes as Single Glazed or as part of an Insulated Glass Unit. It can be used as a Vision Panel or Privacy Panel, side panel or even as a Glazed Partitions. Fire resistant glass can also come with acoustic ratings that can be vital for certain building projects.
Fire-resistant glass which remains transparent in the event of fire offers protection from fire and smoke but does not reduce the transfer of dangerous radiant heat in the event of a fire (integrity only performance).
Glass in this category offers an integrity performance (protection from fire and smoke) whilst reducing transfer of dangerous radiant heat.
Fire-resistant glass in this category offers highest level of protection from fire, smoke and radiant heat for a defined period of time (from 30 upto 180 minutes).
It 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 fromsplinters of glass.
The 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.
Optical glass usage in passenger vehicles has progressed over the years to larger windows for superior viewing and enhanced performance. The trend of using clear tempered glass has now changed to tinted tempered glass which not only reduces glares, temperature and heat but also enhances the ambience inside resulting in an unobstructed view and comfortable travelling experience.
There is also an increase in the usage of laminated glass in busses and coaches with respect to noise reduction, security and safety concerns. In this aspect Burhani Glass has diversified and obtained the E certification to be able to supply high quality glasses for the Bus & Coach market.
