Your choice of glass

As important as the selection of the uPVC windows & Doors is the selection of the glass i.e the glazing.Lingel uPVC Windows & Doors can be delivered with the best glass for your needs: laminated glass, tempered glass, insulated glass, bent glass, sound control glass, burglar resistant glass, and more, even bullet proof glass is available.

The common factors affecting glass choice are:

Solar Control

Solar energy can be pleasant and utilisable in many cases, but especially in buildings, it represents a major source of overheating and unpleasant glare. Solar control glass, usually either body-tinted (absorbing) or coated (reflecting), is used to reduce unwanted solar radiant light and heat energy transmitted through glass.

Acoustic Insulation

The need to restrict sound arriving from the external environment means that glass should be able to shield and insulate the internal spaces of a building. Glass type is the major factor influencing the passage of sound. The most common types of glass used are laminated and insulating glass (Double glazed). Laminated glass incorporates a special acoustic PVB interlayer, which absorbs some of the incident sound energy, reducing its passage. Better sound insulation can also be achieved with double-glazed glass in which vacuum-sealed inner spaces and some gases affect sound insulation and provide acoustic stability.

Thermal Insulation

The U value is a measure of the rate of heat loss of a building component. It is expressed as watts per square metre, per degree Kelvin, W/m2K. Lower U-Values are achieved by multiple glazing layers, gases and the use of low-e coatings.


Glass is subjected to different types of environmental and human loads, which can cause glazed surfaces to malfunction or break. Since each load has a specific impact on glass, with different calculation formulas, it is important to understand each of these phenomena in order to choose the appropriate glass.

Visual Appearance

When we talk about visual appearance we have in mind the color of glass surface. Thanks to the latest manufacturing processes, glass can be made available in several colors. When we combine single sheets of glass in laminated or insulated units, they typically change in overall color and appearance. Glass color appearance can be also conditioned by several environmental factors such as sunlight (midday sun or sunset), reflected sky and clouds, etc.
