Did you know that safety glass resists shocks 5 times higher than regular glass? laminated glass, in case of breakage, does not scatter the resulting shards?
The notion of double glazing, widespread in the market, refers to insulating glass, so a glass with good thermal insulation properties. When choosing to buy a window we must pay attention to the insulating glass (double glazing). Because the glass surface is 75-85% of the window surface, the thermal insulation qualities of the glass are decisive for the thermal insulation of the window.
Thermal insulation glass (double glazing) is an assembly consisting of two sheets of glass, separated by an aluminum spacer. There is also the solution with three sheets of glass, separated by two spacers. Between the glass sheets, a dry, colorless gas is kept, separated from the environment by the perimeter sealing of the insulating glass. The role of this gas cushion is important, the gas cushion being responsible for the thermal insulating qualities of the insulating glass.
There are several solutions for choosing the glass sheets from which the glass is made, for the gas between the glass sheets as well as for the distance between the glass sheets. All this influences the qualities of good insulator of double glazing. The performance of thermal insulation windows is highlighted by the heat transfer coefficient denoted by Ug, measured by W / mpK and which is highlighted on each window. A thermal insulating glass insulates the better the lower this coefficient is.
Glass manufacturers offer a wide variety of solutions. Glass sheets with various thicknesses, clear, matte, colored in mass or provided with metal deposits (reflective), laminated or heat treated, meet the most diverse demands in the construction of insulating glass.
Secured Glass or Laminated Glass?
Glass is constantly evolving, especially in terms of its use in architecture. And for safety reasons, two of the most used types of glass were invented: laminated glass and safety glass.
Although both are used in architecture and construction, the composition and method of production is very different for each of the two types, leading to different advantages and uses. Thus, depending on the purpose of the products intended for glass arrangements, one or the other or a combination of the two will be used.
Laminated glass is used starting from doors and windows, to glass floors and railings, respectively aquariums and shop windows. The strength of this type of glass is due to the lamination foil - if the panel breaks,it holds the pieces of glass together; thus, laminated glass reduces the risk of injury. This is the main reason why it is considered safe, the second being the fact that breaking into a "secure" home with such type of architectural glass, involves not only significant effort but also the production of a lot of noise. Depending on the number and quality of the foil between the two sheets of glass, laminated glass can be a good option in the case of noisy areas, with a lot of traffic, due to the sound insulation properties.
The safety glass is 5 to 10 times harder than the variant that did not go through the safety process. As in the case of laminated glass, one of its main qualities is the behavior of the glass at the time of breaking; Compared to normal glass, safety glass breaks into small pieces and not into large, sharp pieces.
It is used when mechanical shock resistance, thermal resistance and protection against the risk of breakage are desired.
Float glass is made by floating a continuous strip of glass on a metal bath (using "float" technology) and a perfectly flat-faced glass is obtained with transparency undistorted by surface irregularities.
Float glass is based on 4 raw materials that are part of it: - White sand (silica - Soda (Sulfate carbonate) - Lime (Limestone) - Shards of glass in a percentage of 25%). For certain types of glass, metal oxides are added to color the glass in bulk. Uses: It is recommended in cases where a high light transfer coefficient is desired.
Float glass is ideal when it requires good visibility and clarity and is characterized by flat surfaces, light transmission, undistorted transparency, optical clarity. To improve your ambiance, glass can be used, indoors or outdoors, in a variety of ways. For windows, doors, furniture partitions, etc.
The most common solution to obtain an effective insulating glass (double glazing) is to use LowE glass. LowE glass is obtained by depositing (in the factory) a layer of metal oxides on one of the surfaces of a simple, float glass. The thermal insulation of the double glazing is significantly improved by using LowE glass. The layer of metal oxides reflects a large part of the thermal radiation that tends to pass (in winter) from inside the building to the outside, back inside. This characteristic is also the basis of the name, Low E, which in English translates as "low emissivity".
LowE glass is able to meet the highest requirements for thermal insulation, transparency and homogeneity. When designing and installing a low-insulating glass with LowE glass, attention must be paid to the position of the glass face provided with the deposition of metal oxides. The correct position is on face 3 of the insulating glass (double glazing) provided with two sheets of glass, the numbering of the faces being done from the outside to the inside. Therefore, the layer of metal oxides must be positioned on the inner glass and on the face inside the insulating glass (double glazing). Thus, the insulating glass (double glazing) will work properly and eliminates the risk of damage to the oxide layer.
Because the oxide layer is difficult to perceive with the naked eye, especially by a non-specialist, the manufacturer is obliged to label the glass, informing about the presence of LowE glass and the correct mounting position in the carpentry. LowE windows are also used successfully in combination with other types of windows (matte, mass-colored, reflective, laminated, etc.) depending on the requirements to be met by the various insulating windows (insulated windows). They can also be embedded in trypane windows (three-sheet thermal insulation windows), the LowE glass being always positioned in the middle.
Due to its excellent thermal insulation capacity, Low-E glass is suitable both for new constructions and for various renovation works:
single-family and multi-family buildings, office and public buildings, windows, glass doors, greenhouses, facades.
4 Seasons Glass
It is obtained by cathodic sputtering in special installations (magnetron), in conditions of high vacuum and controlled atmosphere. These deposits are characterized by a low emissivity with a double property: they reflect long-wavelength infrared radiation, characteristic of heat from heating and at the same time reflect much of the solar energy. 4S glass combines a high level of thermal insulation with effective sun protection. The low solar factor lowers air conditioning costs and creates a pleasant indoor ambience.
It is the right choice where requirements such as thermal insulation and sun protection, energy control and comfort are specified. Provides energy control and environmental protection: a solar factor of 42% provides effective protection against solar energy, ensuring low costs for air conditioning.
A low U-value reduces heating costs during cold winters, directly contributing to environmental protection by reducing CO2 emissions. Solar control glass filters the different wavelengths of solar radiation, mainly infrared, which would otherwise heat the interior of the building. These are reflected, while allowing natural light to enter virtually without restriction.
At this time of the year, insulating glazing with 4S glass ensures increased comfort - thermal insulation ensures the ideal temperature regardless of weather changes.
Due to its solar control function, 4S glass reflects twice as much solar energy as regular double glazing, without the need for additional sun protection. An ideal temperature - comfort and coolness are ensured even on hot days. Lower air conditioning costs - limiting the amount of solar energy entering the house reduces the need to use air conditioning.
The transition to the cold season becomes imperceptible. Cost reduction - premature heating costs are eliminated.
It offers 3 times more insulation than ordinary double glazing, the advantages being obvious: Heat and comfort - reduces heat loss and significantly reduces the cold area of discomfort near windows. Significant savings - efficient thermal insulation means low energy consumption.
4S glass is ideal for the windows of any new or renovated construction. Its characteristics allow the use of the product both in the residential sector (individual houses, blocks of flats) and in the non-residential sector (office buildings, hotels and restaurants, shopping centers, schools). It combines perfectly with all types of carpentry: PVC, wood, aluminum.
It can be a very interesting design element for any interior. Decorative glass adds charm and, together with a cleverly arranged light, can transform the atmosphere of a room, a bar or a hallway. We offer a whole range of decorative glass designs, but on request, personalized motifs can also be obtained and fit perfectly into your interior design project.
