German Windows & Doors System

KÖMMERLING continued to offer innovative products to its customers: in 1957 it transformed the roller shutter industry with the presentation of the first uPVC roller shutter. Just 10 years later, in 1967 KÖMMERLING introduced window profiles made of modified high impact uPVC.Read more...

Glass Option

Glass should be selected on the basis of thermal insulation requirement (climatic condition), sound insulation requirement (surrounding enviroment condition) and safety requirement. KÖMMERLING windows and doors can accommodate any type of glass as desired and required as per the clients requirements. Following are the type of glasses which can be selected

Float / Annealed Glass

Standard float glass which is generally used in Windows where there is not much requirement of thermal / Sound / Safety.

Tinted Float Annealed Glass

These are standard float glass but pigmented in various colors in order to typically absorb solar radition. Tinted glass takes care to a smaller extent of thermal insulation and to large extent of solar radition.

Reflective Float Glass

These are float glass with metallic coating thus helping to reflect back the solar radiation thus taking care of thermal insulation better than tinted glass and also solar radition. Further since it reflects the light in the day time it ensures minimum visibilty from the outside.

Tempered / Toughened Glass

These are float glass which have been tempered under very high temperature, thus making them times stronger than the normal float glass. Due to heating they become brittle and because of that when broken they shatter into small pieces like automative glass.

Laminated / Shatter Proof Glass

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.

Double Glazing

The insulating glass is a free fabricated unit made of to glass panes supreted by air gap and edges sealed together.

Triple Glazing

Triple Glazing is the introduction of a third glass with a second air gap unit which help in providing greater Insulation thereby providing greater energy saving and greater sound insulation. It is generally installed where lesser sound decibels is required.
