Continuing its leading position in construction materials production, Viglacera Corp. has cooperated with Germany’s Von Ardenne, a leading supplier of glass coating solutions and equipment, to launch a new range of products - energy saving glass - in a move to pursue a “green” technology development strategy.

According to the US’s Energy Information Administration (EIA), the energy used in the building sector for heating, cooling, and lighting accounts for 20.1 per cent of total energy consumption worldwide. Conserving and optimizing consumption, therefore, has become a daunting challenge for administrators.

Strictly complying with DIN EN 1096:2012 Standards, Viglacera’s energy saving glass is manufactured with soft coating (or off-line coating) technology. This coating method utilizes Sputtering Magnetron, also known as Physical Vapor Deposition (PVD), a variety of vacuum deposition methods that can be used to produce thin films and coatings, with several layers of thin metallic and oxide coatings placed onto the surface of pre-cut float glass. The ultrathin compound coating system ensures a reduction in solar heat gain in the glass.

To ensure maximized quality, clear float glass substrates are selected that meet European standards, then cleaned in pure demineralized water. In the sputtering area, standard pressure can reach 1.0x10-6 mbar with complete vacuum pumps.

Optical specifications are strictly controlled by Ex-Situ measurements to guarantee the homogenous status of every glass unit. There are two types of energy saving glass, known as solar control glass and low-e glass.

Solar control glass is a hi-tech product that is ideal for hot climates. With an off-line ultrathin compound coating, solar control glass allows sunlight to pass through a window or façade while reflecting and radiating a large amount of the sun’s heat. The soft coating of solar control minimizes the amount of absorbed heat and solar energy, maximizes natural sunlight, and keeps the indoor air cool.  

Low-e glass, meanwhile, is manufactured with a silver layer and an ultrathin compound coating system. In the winter, it is capable of preventing heat transfer from the indoor space through the glass, which makes the house warmer. In the summer, Viglacera’s low-e glass blocks the sun’s heat and UV rays, keeping the indoor space cooler.

Viglacera’s solar control glass and low-e glass help prevent up to 79 per cent of solar heat and 99 per cent of UV rays, allowing air conditioning costs to be cut by up to 51 per cent in the building sector. They are widely acknowledged as feasible solutions for sustainable development and environmental protection in cities worldwide.
