- Involves heating and cooling treatment whereby high compressive stresses are set up at the surfaces with balancing tensile stresses in the center. - Improves the glass strength against impact and thermal stress loads. - Keeps the original volume, chemical composition, color and clarify of the glass.
Tempered glass is approximately 5 times stronger than annealed glass against impact. Tempered glass is appropriate for using as safety glass because it matters into small, blunt edged fragments, which reduce the risk of injury.
Certain "tempering patterns" which are only visible under some lighting conditions and distorsions within allowable bow&warp tolerances are normally accepted as an inherent and unavoidable characteristic of heat treatment and not a defect.
Tempered glass may have "spontaneous breakages" due to nickel sulphide particles inside float glass. To reduce the risk of "spontaneous breakages" Heat Soak Test is available in our facilities under EN14179 standard. The heat soak test only reduces the risk, it never eliminates.
Yıldız Cam tempering production is under EN12150, and heat strengthened production is under EN1863
Lamegla is the trademark of laminated glass of Yıldız Cam.Produced by combining two or more panes of glass with polyvinly butyral (PVB) or ionaplast (Sentry Glas) interlayer(s).
When broken tends to keep splinters in place therefore minimizing the risks of injury caused by broken glass.Therefore it is called safety glass.Lamegla is produced under EN14449 standard.
Laminated safety glasses prevent (EN12600) or slow down (EN356) break-ins depending on the thickness of PVB,Ionaplast and glass and the extend of the attack.Therefore,it is recommended to use,
Shop windows, Overhead glazing, Glazing up to 80 cm above floor level. Glazing from floor level to ceiling( without any frame in between). Glazing in doors and glazing adjacent to doors as well.
Laminated glasses can be reduced up to 97% UV radiation, which causes fabrics to fade due to PVB and Ionaplast layers.If the UV transmittance is required for the places such as botanic gardens, the UV transmitted PVB and Ionaplast are available.
The body-tinted glasses having different colors, like blue, bronze, green, grey are called sun control glasses. The glasses have high level of energy absortion. We advice ascertaining whether the glass should be tempered.
Tinted Float is the trademark of tinted glasses of Trakya Cam.
Sound control glass can be produced by using "Acoustic PVB" which is 1.14 mm in thickness or 0.76 mm in lamination.
It is possible to create 3-4 times of difference between "exterior" and "interior" noise levels by sound control glasses. It is possible to create combinations which have 50 dB (decibel) noise isolation.
Yıldız Cam, which entered into the sector by retail glass sale in 1978, began wholesale glass sales in 1985. Yıldız Cam developed its sale network by active sale policy and was entitled as Şişecam Authorized Dealer in 1990. It continued to develop itself by following innovations and developments in construction sector which use glass intensively and by being entitled as authorized producer Şişecam in 1992. By making new investments in order to meet requirements of other sectors using glass in 1994, it started to produce processed glass in the same year, tempered glass in 2000 and laminated glass in 2005. It started to produce fusion glasses and serigraphic printed glasses in 2006 by following developments in processed glass closely and taking the importance of change as a principle. Yıldız Cam will carry on its sectoral developments and activities in order to protect and serve its best quality level. Yıldız Cam is working and making investments since its inception for giving better service; it is renewing and developing itself.
Products we produce contribute to total quality chain of firms we supply. Our target is always to keep best quality level and to be best supplier by ideal supplies.
