High-quality insulating glazing reduces energy costs from heating. Thanks to the higher surface temperature and improved joint impermeability, air inside the room doesn’t cool down saving energy, heat and costs. Additional solar protection can also be added as required.
In single pane safety glass, the stability under tension is increased so as to better resist temperature fluctuations and cracks. If broken, it breaks into tiny pieces with many pieces still hanging together to reduce potential injury, especially from sharp edges. Single pane safety glass is often used in vehicles for example, in the side and rear windows. In home windows, it reduces the possibility of stress fractures occurring and risk of injury.
When employing laminated safety glass there are at least two panes of float glass, which are coated with layers of tear proof 0.38 mm thick polyvinyl butyral (PVB) foil. Under pressure and at high temperatures - after laying the panes on top of each other together with the foil - the two materials are pressed together and then finally molded together under the heat of an autoclave.
Also known as ornamental glass, it is given its characteristic surface structure via a special rolling technique. This helps reduce visibility but not light transmission which is ideal for interior places requiring both light and privacy, such as bathrooms. Its decorative appearance makes this a popular choice for doors, windows and facades.
However, ornamental glass can break more easily meaning a fine mesh wire is generally incorporated to boost its toughness. Nevertheless, wire-reinforced glass is more liable to break than float glass and therefore not suitable for use as safety glass.
Acoustic insulation entails thicker panes designed to substantially reduce outside noise. For sound reduction, the entire window's performance has to be evaluated, including the frame, not just the glazing itself. Homeowners in busy areas will hear a noticeable improvement in outside noise by replacing old windows.
Solar control glass is used in order to avoid and minimize extreme increases in the indoor temperatures. The glass panes are treated with a reflective coating or an absorbant, colored layer (iron oxide or copper oxide). The advantages of solar glazing include:
