In the second part of this article, we shall talk about the types of glass, as they play an essential part from the windows and doors glazing. The glass used for your windows glazing will contrubute greatly to the thermal or sound efficiency of your home or office. 

High - Energy Glass

High-energy glass combines the characteristics of low-emission glass and sun protection glass. The coating of the glass is multi-layered, including layers of different precious metals, as the metal layer is applied unilaterally. This coating of the glass has a low conductivity, reflects the high-frequency infrared radiation characteristic of thermal energy, and at the same time reflects a large part of solar energy. Its efficiency in all seasons and its proven qualities in improving the thermal efficiency of your home make it one of the most commonly used glasses in double-glazed windows. The high-energy glass integrated into the glazing will reduce your costs for heating or cooling your home by about 40%, compared to ordinary double-glazed units. It is mounted on the outside of the glazing.

Soundproof Glass

For better sound insulation, glasses with a greater thickness are usually used - 5, 6 mm instead of 4 mm. The greater the thickness of the better absorption of resonant oscillations and reduced street noise. The use of laminated glass (triplex) in the glazing will also improve the sound insulation. To achieve an even better effect in the sound insulation, triple glazing is often used, and added argon gas in the glazing increases both sound and thermal insulation.

Sun Protection Glass

Sun protection glass is used for both single and double glazing units. When integrated into the double glazing unit, it is mounted on the outside. This glass limits the entry of shortwave solar radiation into the room, thus reducing the total heat load. A special coating and a layer of metal oxides applied to the surface allow this type of glass to reflect up to 2/3 of the heat of the solar spectrum, leaving the room cool. Despite the limitation of penetrating heat, the sun protection glass provides good natural light, transmitting 60 - 70% of light and only 30-35% of infrared rays.

Fireproof end Anti-burglary Glasses

Laminated glass (triplex) is obtained by glueing two or more layers of float glass with PVB resin or foil. The PVB resin layer gives the triplex higher resistance, improving sound insulation properties and also brakes over 90% of the transmitted ultraviolet light. This type of glass is widely used in the glazing of balconies, glass roofs, glazing of buildings located in noisy areas and other.

Tempered glass

Tempered glass is glass that has undergone a thermal tempering process, which increases its mechanical strength of impact and pressure. The fully tempered glass is 4 to 5 times stronger than non-tempered glass of the same thickness. In the event of a strong or sharp impact, the tempered glass breaks down into small safe particles without sharp edges, which significantly reduces the likelihood of injury. This property of tempered glass makes them safer and therefore they are widely used in public buildings glazings. Tempered glass is easily recognizable when viewed at an angle, where you can clearly see spots with shades of various colours.
