What is the coefficient of thermal resistance and heat transfer coefficient?

The heat transfer coefficient - a parameter glazing characterizing the heat transfer through the central area of glazing, which is the ratio of density of a stationary flow or low temperature environment on different sides of the glazing. The value in most cases is calculated for vertical glazing under standardized boundary conditions. The lower the value of heat transfer coefficient, the lower the heat loss of the premises, and the more reduced heating costs. Specifications, which indicates our company apply only to the glazing. They are often called the coefficient of heat transfer resistance in the central area of glazing, without taking into account the heat loss of the marginal zone glazing or window frame.

Arbitrariness whether fire rated glass?

We do not produce fire rated glass.

Does your company laminated glass? Can I laminated low E glass and multifunction?

Our company produces architectural laminated glass with different thickness and sizes, and many architectural glass by magnetron sputtering

Why do windows sweat? How to avoid this?

To predict the temperature of the air, which would occur when the fogging of windows and their loss on condensation, it is necessary to take into account variables such as domestic room air, outdoor air, absolute and relative humidity of internal air. At low outdoor air temperature, the temperature on the inner surface of the glazing will be significantly lower than the air temperature inside the building (in the middle of the room at a height of 1.5 m), which leads to loss of "excess" of water vapor on the cold inside glass surface in the form of condensate or freezing fog. Without going into specific formula, the value at which the indoor air temperature is the temperature at the inner surface of the glass, corresponds to the dew point (at which condensation). For example, the temperature on the inner surface of glazing installed in a room with a temperature of the internal air near 20 degrees and indoor air humidity of 60% under the condition of falling ambient temperature to a value of -30, is substantially below the dew point, resulting in the precipitation of an abundant formation of condensate and ice inside of the windows of the room. In most cases, when someone install glazing in order to save, there is a problem of forecasting the periods in the cold season, when indoor condensation will fall.

Why aluminum profile is hollow?

To reduce weight of a product and material saving. The inner space of the profile is filled with cross webs which serve as stiffeners inside the structure. They form a plurality of compartments filled with air. These air chambers inside the profile provide high thermal protection.

Which producer’s profile do you use most often for creating aluminum structures?

We work with Alutech (Belarus), Reynaers (Belgium), Aluprof (Poland) profiles. These companies differ from others in that they are not only producers, but also competent developers of new technologies for the production of aluminum profile systems. All innovations are thoroughly tested in their own R & D center. These profile systems are a kind of designer. It means that all blends easily, thanks to the harmonized system "all from one source."

What does “warm” and “cold” profile mean?

In the design of "warm" profile is an element called "thermal insert" that allows you to solve the problem with the condensate arising from the difference in temperature on the inner surface of the profile. The "cold' profiles doesn't have such thermal barrier. Application of "warm" and "cold" profile depends on the temperature, which would affect the aluminum structure from the outside.

GENERAL QUESTIONS

How to order a sample of the product?

You can easily get a brand SunGuard glass samples measuring approximately 290 mm ​​x 210 mm for the project at the company's representative in your region

Which of Guardian products available in stock? What are the delivery times?

Architectural Glass SunGuard brand includes a wide range of hardened glass sputter coated. Glass can be recycled at one of the closest to the location of your project. We recommend a certified recycler. This is to minimize the delivery time window on new orders and replacement. The presence of a specific volume of glass or that kind of fill in your details and you will be contacted manager.

What is the solar factor and shading coefficient? What are the differences between these concepts?

Solar factor - is the cumulative amount of solar energy that passes through the glazing and directly re-emitted (absorbed glass surface and re-emitted into the room). Shading coefficient - the ratio of the solar factor glass to the value of the solar factor of clear float glass 3mm (0.87 or 87%) The lower the shading coefficient, the less the amount of solar thermal energy.
