In interior spaces windows are the initial cause of heat dissipation. People have been looking for a solution to heat the exterior spaces in winter and protect interior spaces from exterior heat in summer for centuries. In most of the constructions, small windows have been built, the scenery and sunlight has been partially sacrificed and construction expenses have increased.
 

Using the most recent high technology in window production, Wintech has been the trademark by maximizing scenery and natural sunlight options and providing the best thermal and water insulation.
 

Three and five chambered profiles with three and two effective seal system in frame wing combinations, stabile air channels and 2 and 3 manias occur along joinery. These qualifications leave the negative conditions of exterior environment outside and maximize the interior comfort. Comfort in interior spaces is felt without sacrificing natural sunlight and wide scenery.
 

A window does not only mean comfort and appearance in a building. It is a source of savings with right choice and correct application methods. Wintech meets the expectations of customers from a window by using double glaze and specially insulated glasses instead of single glaze application on a window.
 

The comparison of a single glaze wooden window and double glaze plastic window exchange in a space has been presented as follows:
 

External Temperature
(External Temperature -15′C)

U Value of Glass W/(m2 K) 

Internal Temperature
(Internal Temperature 20′C) 

-6.2’C

5.8

-5.4’C

-10.4’C

3

+6.9’C

-13.0’C

1.3

+14.3’C


U = Heat conducting coefficient
 

As seen above, the external temperature of the external glass section decreases as the U value decreases, however, internal temperature of internal glass section increases. The U value for 60mm width is 2,6 W(m2/K)
 

The decrease of the U value of a PVC window enables heat saving as follows:
