Double glazing
double_glazingGlazing is hermetically closed construction of two or more windows, separated from each other with different sized spacers. In most cases, glazed windows from 75% to 90% of the area of the window and it is therefore essential to choose quality, satisfying all desires for heat and sound - insulating glass, not just high-quality joinery. Depending on the number of windows that make up glass, they are: double (single) or triple glazing (two-chamber) glass. Thermal insulation is best achieved through a combination of high quality profile with the necessary thermal insulation and appropriate glazing. The degree of insulation depends on the distance between the panes, the type and thickness. To increase the thermal insulation is recommended that the low-emission glass in the glass. It is a float glass bearing a thin layer of metal oxide and glass it is almost 2 times better insulator than glass with two white float glass 4 mm thick.


The coefficient of thermal conductivity U indicates the amount of heat that passes through one square meter of glass for 1 hour at the difference in temperature on both sides - 1 degree. Putting argon gas, reduces energy losses and increases the insulating properties of glass by about 10% (from 0,1 W/m2 K to 0,2 W/m2 K). Higher thermal insulation performance can be achieved by placing the triple (dual-chamber) glazing.


Another problem is the noise that determines the placing of different thickness on glass slides. Sound passes easily through the same thick glass, for example, two windows with a thickness of 4 mm. but bends and does not cross the room if he had to pass through media of different thicknesses. Glazing - two glasses of different thickness or glazing, which is one of the triplex windows ensure excellent sound insulation. Maximum sound can be achieved by a triple (bicameral) glass with different thickness of glass and different distances between them, especially if one of the three panes are laminated (triplex).


double_glazing2Depending on the type of the input glazed windows different effects can be achieved. Main types of glass used in construction are:
- White float glass. The most commonly used glass in most cases in combination with other glass and comes with different thicknesses (4 mm. up to 8 mm.)
- Low-emission glass is energy efficient glass, which achieves better thermal insulation. Its outstanding thermal insulation properties - let maximum solar energy and retain large amount of heat in the room.
- All-season glass is energy efficient glass, which achieves optimal thermal insulation, combining control of sunlight and insulating capabilities, providing a pleasant environment throughout the year, without producing "greenhouse" effect. Characterized by high selectivity and low coefficient of thermal conductivity. Suitable for windows with south and southwest view.
- Laminated glass (Triplex: 3.1.3, 4.1.4 or 5.1.5 mm) laminated glass is a multilayered type of glass, joined together by high-tension-film. If broken this glass does not break into pieces and stays in the frame. It has an extremely high degree of soundproofing.
- Reflective glass - Stopsol is suitable for walls or roofs. There is increased solar control and high resistance to scratching and staining.
- Tinted glass. There are tinted blue, green, brown and gray lenses that are suitable for making glass for windows and doors.
All hermetically sealed space in all windows can be filled with argon gas, which improves the coefficient of thermal insulation and reduces energy loss.
