• Base product for all other glass types.
• High light transmittance thanks to its transparency.
• Continuous and uninterrupted supply in different thicknesses and sizes.
• A wide distribution network spread all over Türkiye.

Areas of use

Subprocesses (e.g. edge processing, curving, tempering, partial tempering, lamination, coating, double glazing, mirroring) allow the use of Şişecam Extra Clear as safety and security glass, heat control glass, solar control glass, noise control glass, heat and solar control glass, and decoration glass.
Subprocesses add many functions to Şişecam Extra Clear and allow its use in many industries, including construction, decoration, automotive, white goods, agriculture, and energy.

Production method

• Şişecam Extra Clear is produced with float technology, which is the world standard in high quality and flat glass production.
• Flat (float) glass is obtained by floating glass melting on molten tin.

Float Glass Production

Float Glass is produced by float technology as follows:

The glass blend, a mixture of raw materials with certain properties and quantities, (notably sand, soda, and limestone), is melted in the furnace at approximately 1600°C. The glass melt is poured from the furnace into the molten tin bath at approximately 1100° and by floating the glass on the tin, the two faces are ensured to be flawless and parallel to each other, while creating a glass thickness and a ribbon width. Once the glass ribbon comes out from the tin bath without interruption, its temperature is lowered in a controlled manner and the stress within the glass is relieved in the cooling section. The glass is then cut into the desired sizes on the cutting line, collected in packages, and made ready for shipment.

Flat (float) glass is the basic product for architectural and automotive glass use and can be used as it comes off the production line or after undergoing different processes such as lamination, tempering, coating, and mirroring in order to improve its basic properties. In this way, it is transformed into an impact-resistant, safe, and decorative material that provides heat and sound insulation, and solar control, as required.

Size and Thickness

Şişecam Extra Clear is produced in standard thicknesses of 3 mm, 4 mm, 5 mm, 6 mm and 8 mm and various sizes such as 3210x2140 mm, 3210x2250 mm, 3210x2550 mm, 3210x6000 mm, 3210x9000 mm and 3210x12000 mm.

Processing Principles

Storage

Transport glass packages or crates at a 5° angle vertically. Stop stacking crates when they begin to lean and empty that row promptly.
Do not store packages or crates outdoors. Store them in a closed environment with appropriate humidity and temperature conditions for ideal storage, a temperature of 9-25°C and humidity below 70% is recommended. Protect the packages or crates in stock from water (e.g. rain or snow) that may cause the glass to get wet. The glass that gets wet in stock has a high risk of corrosion. Therefore, if the glass plates get wet due to condensation or in any way, clean them before they dry.

When loading and unloading glass packages to/from the stands, place and/or unload them evenly on both sides of the stand.
It is recommended to use only rubberized wooden stock wedges when stocking jumbo packages.
Use wooden or metal (rubber) stock wedges for machine size and split stocks.
Use rubber parts to compensate for the level differences caused by the floor between the stand leg and the stock wedge.
Wooden wedges should be made of kiln-dried hornbeam or beech.
Never store packages with broken or cracked plates.

Washing

The water to be used for washing the glass should have a hardness of maximum 5°Fr and a pH between 6 and 8. It is recommended that the electrical conductivity of the washing water be lower than 1 µS/cm for glass to be coated off-line and 30 µS/cm for insulating glass. The brushes in the washing machine must be soft enough not to scratch the glass. Water on the glass must be removed with an air knife before it dries.

Transport/Handling (in-house use)

• Transport glass packages or crates at an angle of 5° to the vertical, not horizontally.
• Outdoor transport must be done in covered vehicles that are protected against wetness and dust.
• There must be no cracked or broken glass in the package. Cracked or broken glass can scratch the glass in front of and behind it and cause serious workplace accidents as well.
• Place glass packages on rubber and felt surfaces. Do not place them in direct contact with metal or wood.
• Use proper dust or paper separator between glass plates. Improper separator materials may cause scratches, dents, cracks, and corrosion on the glass.
• If paper is used as a separator material, it must be ash-free and have a pH between 5.5 and 7.
• All separator materials must be clean and dry.
• Loading and transport equipment must not be damaged.
• During transport, secure packages or crates to the transport vehicle.
• Load and unload packages or crates onto/from the transport vehicle using equipment appropriate to the type of packaging of glass. Inappropriate equipment may cause work accidents and glass breakage. Take the necessary work safety precautions before dismantling the glass packaging.

Cutting

• Use the appropriate cutter's relay, cutting oil, and cutting pressure.
• After cutting, break out the glass immediately.
• Make sure the surfaces of the cutting tables are smooth and clean.
• Make sure that all sides of the glass plate to be cut are at the same temperature. The glass that is exposed to sunlight on one side and heated may not be cut properly due to temporary stresses.
• After cutting, break out the glass immediately.
• Cutting and breaking problems in heat-treated glass at temperatures above 480°C are caused by the subprocess.

Quality

Şişecam Extra Clear is produced in compliance with TS 10288 EN 572-2 Glass in building - Basic soda lime silicate glass products - Part 2: Float glass.
The production also complies with the ISO-9000 Quality Management System and ISO-14000 Environmental Management System.
