Aluminum windows are structurally stable and resistant to weather conditions. They do not age and are easy to maintain. Their advantage is that their staining profile is not expensive and the possibility of combining colors are higher than the PVC where colors other than white are often significantly increasing the final cost of the product. People do not decide to install aluminum windows because of the high price. If you are interested in buying new windows, visit us today.
Plastic windows have better thermal insulation than aluminum, but the aluminum window have better sealing and better sound insulation. Price is quite lower than the aluminum, but may have a shorter lifespan, and are unacceptable from the environmental aspect since their production and recycling is polluting the environment (some profiles contain cadmium, toxic plasticizers and means for protection against fire).
It should be noted that there are people who reported problems with their PVC windows in the first winter after installing them due to temperature differences which caused a large expansion or shrinkage of the windows.
The next question is what kind of glass should you install? To minimize heat loss, laminated glass is a standard glass for aluminum and PVC windows. Laminated glass is a glass body consisting of at least two sheets of the glass surface, where the intermediate space is filled with dry air or another type of gas, for example, argon. The quality of the windows depends on the quality of materials and production procedures.
Types of glasses:
Float glass is a flat transparent glass, and incorporated in the thicknesses from 3 mm to 10 mm.
Laminated glass is composed of several float glasses and a glued foil. This glass is used for security reasons because it does not break into small pieces when damaged.
Tempered glass is float glass that is heat-treated to improve the mechanical properties. In case of breaking into pieces, it is very safe.
Patterned glass is glass in which the surface is decorated with various patterns.
Reflective glass coated with metal film portion
According to the new technical regulation on thermal energy savings and thermal protection in buildings low – chemical glass windows are required in new buildings. Windows with such glasses have a heat transfer coefficient of around 1.30 W / m2K, which is certainly a recommendation when buying new windows when renovating old buildings. The principle of the low – chemical glass is that the glass has a thin layer based on vanadium dioxide. This layer prevents the passage of heat radiation through the glass during summer.
In the end, it is extremely important to pay attention to the quality of the sealing. After examining the cross-section of the window profile, you can see that the connection of the window sash and frame, creates a complex structure that prevents the passage of air and water. The outer part prevents the infiltration of water to the inner part of the window.
