GLASS TYPES

ANNEALED GLASS

vidro-comumIt is the ideal glass for applications requiring perfect visibility, as has no optical distortion and has high light transmission. It is composed of silica (sand), potash, alumina, sodium (soda), magnesium and calcium; everything is diffused, accurately mixed and melted in the furnace at approximately 1000°C.

Key Benefits    

•    It is the raw material for processing all other flat glass and is used in different segments.
•    Can be used to form the laminated, toughened, curved, screen-printed glass and used in double glazing.

Normally does not receive any special treatment, the glass is cut and polished, can be used in several applications. Made available to the market in colors: green, smoked, bronze and colorless.

 

LAMINATED GLASS (SAFETY GLASS)

The laminated glass that is part of TOSATTI systems combines aesthetics and safety in one system. This type of glass is composed of two sheets of glass intercalated by a high strength plastic film, the polyvinyl butyral (PVB). If there is an accident, the glass fragments are trapped in the PVB film, which remains intact, avoiding injuries and preserving the environment. The use of laminated glass provides more peace of mind to indoor environments and makes them more relaxed and comfortable, because, besides all the security it provides, it reduces the excessive external noises. Laminated glass also filters 99.6% of ultraviolet sunrays (UV), protecting people from sun damage and minimizing the fading of furniture, curtains, carpets and other objects.

vidro-laminado-enKey Benefits

•    Security for assets and people, reducing the risk of injury.
•    By breaking, does not require immediate replacement of the glass.
•    Acoustic control, reducing the inflow of external noise.
•    Better protection against fading and aging of furniture and objects from the sun.
•    Variety of colors.

Because it is a safety glass, according to NBR 7199, is especially suited to ensure the integrity of people and property in the event of shocks, falls or impacts. Its application is recommended for facades, roofs, railings, balconies, doors, windows.

 

TOUGHENED GLASS

vidro-temperado Toughened glass is considered safety glass and is produced by a horizontal or vertical tempering furnace. Annealed glass (float) is subjected to rapid heating and cooling process making it more resistant to breakage by impact, presenting thus strength five times higher than the annealed glass. Once toughened, the glass can not be benefited, cut or punctured; therefore, any process of transformation must be done before the tempering process. To be framed in the systems of TOSATTI, toughened glass gains protection in its corners which are protected within the PVC profiles, making it even safer.

Key Benefits

•    Resistance five times greater than the annealed glass resists thermal shock, weight, bending, buckling and twisting.

It is considered a safety glass because in case of breakage, it breaks into small pieces rather sharp which lowers the risk of injury.

 

PATTERNED GLASS

The patterned glass, also known as fantasy glass, is produced by passing a strip of molten glass between rollers of 900 degrees. Thus, embossed designs on the rollers are transferred to glass. I. e., in their manufacture, are used the same raw materials and basic inputs used in the annealed glass process.

vidro-impressoThe difference is the use of two metal rods at the furnace exit through which the already prepared glass passes (melt). The upper roller is smooth and the lower holds on its surface recording design (standard) you want to print on glass. The spacing between the two rollers determines the thickness of finished product.  After printing, the flat glass that is not completely rigid, is driven by one set of rollers called extend, where the cooling process occurs slowly and gradually. Then the glass sheet is cut into the planned size. The patterned glass can receive processing as laminating, tempering, mirroring, blasting and beveled.

Key Benefits
 
•   A key feature of the patterned glass is smooth and uniform design that has the property of spreading the light and the sun rays while maintaining the privacy of environments without losing brightness. With a huge range of textures, colors and thicknesses, the form provides various decorative effects, privacy and comfort.

 

REFLECTIVE GLASS

vidro-refletivoDeveloping technology that ensures the efficient control of light intensity and heat transmitted to the indoors, the reflective glass, popularly called mirrored glass, are great allies of environmental comfort and energy efficiency in buildings.
The transformation of float glass in reflective glass consists of applying a metalized layer on one of its faces, made by pyrolytic processes (online) or vacuum chamber (offline). In the online system, the metalized layer is sprayed with metal oxides during the manufacture of float; in the offline process, the glass sheet passes through a vacuum chamber, which receives the deposition of metal atoms on one of its faces.
The reflective glass can be laminated, insulating, silk-screen printed or toughened. However, some care are necessary in special situations: the glasses that pass through the vacuum process can not be tempered and the screen printing process should be done before depositing oxides. The reflective pyrolytic can be tempered and screen printed after the pyrolysis process (decomposition by heat).

Key Benefits

•   The advantages are many: differentiated performance for solar control in relation to the transmission and reflection of light and heat, and low shading coefficients; reduction up to 80% of the heat of solar radiation passing into the atmosphere, thus ensuring excellent thermal insulation; barrier against ultraviolet (UV) when laminated; saving power consumption by decreasing air-conditioning use, a result of thermal control that reflective glass provides; control of light incident on the glass: feeling of comfort to the user and rational use of electric light.

 

DOUBLE GLAZING

vidro-duploThe double glass, also called insulated, has thermo-acoustic function; depending on its composition, can provide thermal and acoustic insulation. The double glazing system combines the technical and aesthetic advantages of at least two types of glass. Between the two glasses there is an inner layer of air or dried gas – double sealing. The first seal prevents gas exchange, while the latter ensures the stability of joint.

The double glazing system can be composed of any type of glass (toughened, laminated, colored, colorless, metallic and low emissive), highlighting the qualities among them.

I. e., you can combine different properties glasses, as the strength (external) of toughened glass with thermal protection (internal) of the laminated. The glazing may also contain an inner shutter (between glasses). This system combines all the advantages resulting from double glazing, as the backlight control and privacy.

Key Benefits

•    The double glazing offer privacy, maximum use of natural light without losing brightness control (entry of light and heat), thermal and acoustic insulation (attenuates the sound waves at levels higher than the ordinary glass with best result by using specialty gases) and durability.
