This glass is manufactured by gradually heating a piece of glass up to approximately 620°C (1148°F) and rapidly cooling it with air, creating a product with compressive forces on the surface and tensile stresses in its center. This distribution of forces creates a glass four times more resistant to deflection than normal glass that withstands a temperature differential of up to 250°C (482°F).

Its manufacturing process consists of increasing the glass temperature up to 620°C (1148°F). Cooling is slower than in the tempered glass process, creating a glass two times more resistant than normal glass.

This process reduces waving and bending, and offers aesthetic benefits. Compared with normal glass, semi-tempered glass has a higher resistance to thermal stresses, wind loads and wind-blown objects.

Even though the structural behavior of semi-tempered glass is better than in normal glass, it is not considered a safety glass as its breakage pattern is similar to normal glass.

Tempered and semi-tempered processes are required in the manufacturing of glasses with ceramic coating (Vitrospan absoluto and Vitrospan grafik).

Considering the need to create alternatives that better adapt to the natural conditions of our planet, we have designed the Duovent® Units, the ideal solution that provides precise benefits for each project. Duovent Units are formed by two glass panels that hermetically seal a space of air with an aluminum separator and thus provide better thermal and acoustic insulation. This process reduces heat considerably and avoids heat loss during winter.
Thermal insulation is the main feature of the Duovent Units. The amount of air space determines the degree of thermal insulation. Color glass, reflective glass and laminated glass can be added to the unit to obtain better control of solar radiation. These units also have acoustic insulation properties and can therefore be specified when noise reduction is required. Duovent Units are frequently used today for hospitals, schools, offices, residences and any building where there is a need for environmental, thermal or acoustic control.

These products contribute to LEED certifications for buildings and constructions, and provide architects and designers a real solution while contributing to energy savings and the conservation of the environment.

The lamination process consists of two glass sheets and a polyvinyl butyral (PVB) interlayer, bonding the elements through a simultaneous controlled heat and pressure process; the result is an excellent optical quality sheet. The glass’ adherence to the polyvinyl butyral (PVB) is an advantage if the glass breaks. On the one hand, this condition protects the user in direct contact with the glass, and on another, it avoids the glass from becoming detached, so long as it has an adequate support system.

Depending on the specified resistance requirements, the laminating process can manufacture pieces in various glass thicknesses with polyvinyl butyral (PVB), clear or tinted, with an anti-hurricane film (Sentryglass), in combination with annealed glass, thermal treated glass, reflective glass and color substrates.

The main features of this type of products are their safety and acoustic insulation.

Flat glass can be painted with ceramic paints by means of a serigraphic process that uses a stencil or roller as a model to obtain multiple copies of one design. The glass is submitted to a paint drying process, which can use an oven with temperatures of 160°C (320°F).

When the required layers of paint have been applied, the glass must be tempered or semi-tempered. The result is that the paint is integrated to the glass mass by “glazing” and therefore will not come off easily when the surface is scratched.
This type of glass is ideal for domes and skylights as an exterior sheet for a Duovent® system, and in its semi-tempered mode, it can be included in laminated glass. It is also used to cover structural areas in buildings, such as suspended slabs, drop ceilings and exterior columns, and in general any area where the design requires a decorative element for the building, both in exterior as interiors.

One of today’s most innovative processes is ceramic printing on glass which enables any photograph and multicolor image to be captured on the glass.

This process digitalizes high definition images by using special software and then prints these images using specialized equipment. The glass must be tempered after printing to guarantee the paint glazing, which makes this a safety product.
