The right selection of glass is as important as the selection of the right uPVC windows and doors for your home. Available in a wide variety to meet specific needs, glass not only helps in energy efficiency concerns, but lowers the overall energy costs as well. Factors like, the insulation requirement (climatic condition), the sound insulation requirement (surrounding environment condition) and safety requirement, determine the selection of the right type of glass option for your uPVC doors and windows.
The following are types of glasses which can be selected:-
Float or annealed glass is one of the most commonly used form of glasses
These glass varieties are pigmented in various colors in order to typically absorb solar radiation. Preferable in saving energy concerns, tinted float annealed glass undertakes thermal insulation and to a larger extent of solar radiation.
Floating glass with a metallic coating, reflective glass helps in reflecting back the solar radiation, thus taking care of thermal insulation better than tinted glass and also radiation. Also, it ensures minimum visibility from the outside.
These glasses are tempered under very high temperature, thus making quite stronger than the normal float glass. Due to heating, they become brittle and because of that when broken, they shatter into small pieces.
When two glass sheets of any of the above mentioned glasses are sandwiched together with one or more layers of PVB plastic or resin it is called laminated glass. The process of sandwiching/lamination makes the glass much stronger and prevents easy breakage. Due to PVB Plastic or resin in between the glass does not shatter when it breaks.
