Selecting a glass for your windows
The glazing represents about 80% of your window area. Therefore, there should be no compromise in his choices - investments in a good glazing, will be recuperated for a relatively short period.
The glazing is a modern version of double glazing, in which two or more sheets of glass separated by an air gap and a spacer are joined together in a general hermetic module suitable for embedding. Designed primarily for external glazing.
To provide dry air in the space between the glass panes, the spacer frame is filled with an absorber. The frame is glued to the glass double-sided with butyl, which appears to be the first barrier against water vapor. A second barrier uses a resilient vinyl seal with polysulphide, polyurethane, silicone or hotmelt.
Your desire for low heating and cooling costs.
To help you - our customers, we have summed up the characteristics of the various glass panes and the purposes for which they are suitable to be used
Before choosing a glass package, it is important to comply with the following basic requirements:
The climatic conditions of the area;
The purpose of the building (home, office, villa, hotel, etc.);
Orientation of the building towards the sun (east, west, north, south).
Transparent (float) glass - transparent glass is the most common in modern production. By special technology, in which molten glass mass is placed in bathtubs with molten lead, which is gradually cooled. The transparent (float) glass thus produced has exceptional smoothness and is free of any optical defects.
Low-emission glass ("K" glass) - It is a high-quality transparent float glass, one of which is coated with an ionized layer of metal oxide (titanium-plated). Low-emission glasses improve thermal insulation by keeping heat in the rooms and reducing heat loss through the window by over 60%. Placing K-glass reduces the risk of condensation to a minimum, because the thermal insulation coefficient is close to that of the PVC profile.
All-glass Energy Glass - this glass is a modified glass with a soft finish and two super thin silver layers, providing its unique qualities: maximum light transmission, cold insulation and solar heat reflectance. Typical of this is that it reflects up to 70% of the heat of the infrared rays. So in winter the room is warm and in the summer cool. With this new glass design, you will truly enjoy home-like comfort and comfort throughout all four seasons.
Ornamental glass - Produced on the principle of transparent or colored glass, but after special processing of relief ornaments on one or other part of the glass, by special technology - rolling. It has an aesthetic look and is often used in interior doors, partitions, offices and more.
Laminated Glass (Triplex) - Produced by bonding two or more layers of usually transparent glass between which a special layer of coating, most often polyvinyl butaryl (PVB), is placed. Processing of laminated glass is accomplished by a machine process. Several of the main advantages of the triplex is that the intermediate layer retains the two layers of glass bonded even after breaking, and its high strength prevents the glass from breaking into large sharp pieces, which is a guarantee of burglary resistance. In laminated glass, the sound insulation properties are greatly improved, while at the same time it stops 99% of the ultraviolet rays. It is used for glazing of facades, balconies and windows.
Reinforced glass - Steel wire mesh pressed between two semi-melted glasses is produced in glass. Impact and fire resistance. The reinforced glass can be directly applied as an ornamental protective glass. When broken, the wire mesh keeps the glass, which is especially important in case of fire, burglary and resistance to earthquakes.
The general window thermal insulation UW [W / m2k] is determined on the formula in which the main factors are:
- heat insulating qualities of the glass Ug [W / m2k];
- heat insulating profile qualities Uf [W / m2k];
- the specification of the windows and their length in the window construction.
Thermal insulation of double glue glass with float glasses UG = 2.8 W / m2k
The use of regular low-emission glass improves insulation with over 50% up to norms Ug = 1.4 W / m2k
The use of the specific low windscreens and their combination in the glass packet can reduce the value to Ug = 0.6 W / m2k, which gives effectiveness from up to 75%
The use of specific low windscreens is more expensive , but on a long-term plan, the effective decision to minimize the costs of energy efficiency of accommodations.
For choosing the right glass packets, you have to follow the following requirements:
- climatic area in which is the building; - the exhibition of windows on the sun
- the time use of the site (whole year or seasonal).
The same factors are definition for choosing of profiling system. Thermal insulation of the systems,that we are using for our windows are from uf = 1.4 to uf = 0.9 w / m2k.
For the correct choice, you may also consult with our specialists.
Sound insulation is measured in [dB] - reduced noise.
If windscreen insulation is 30 db, at a strong external urban noise 80 dB. The sound from the outdoor entering the room is 80-30 = 50 dB. In such cases, it is necessary to select a glass and a profile with better noise levels to lead to 30-35 db norms in the premises. The most inexpensive option is to use triple glass packet with different glass thickness and the different dimensions of the glass spacers. Such combination may reduce significant interference frequency of vibration and reduce noise in accommodations. For a serious necessity of sound insulation there is a specific glass which have such qualities - acoustic laminated glass (stratophone glass)
Condensаtion on the glass of the window does not indicate that the glass packet is incorrect. The main cause may be some of the following factors:
- if the glass is damaged (leaky or drychmethized);
- incorrect choice of glass with lower insulating qualities from the window profiles.
There is therefore a clear air cooling above the profile and in the width of the window a condensation is displayed. We need to change the glass with low-emition type - for the cold weather, the temperature in the room is close to the outside temperature. In immediately hot heating rooms moisture in the air fast condenses with chilled glass.
