|MEGRAME® GLAZING UNITS
Glazing units are very important part of windows and doors. Window characteristics depends on the glazing method. Glass units make up a large area of the product, so most of the heat can be lost through the window glazing unit, but also it can be gained through the glass as well. For this reason, the thermal insulation of a window largely depends on its glazing. Glazing units also determine window sound insulation level.
In order to purchase energy-effective glazing units, you should pay attention to the following key elements for achieving the maximum effect:
- Double or triple glazing: (2 or 3 sheets of glass in the glazing unit). Triple glazing unit is almost twice as warm as a standard double glazing.
Note that the accuracy of the shades displayed on your computer, phone or tablet screen depends on its specifications and may differ from physical color palette.
Spectrally-selective Low-E glass keeps heat inside the room and improves thermal characteristics of windows. You can reach the highest effect of energy saving when glazing windows with triple glazing units that are filled with argon. For this reason, triple glazing is used for buildings with high energy saving requirements. Also, triple glazing has very high sound insulation - as a result, triple glazed windows are the most common choice for the individual houses as it ensures comfort and saves energy.
ADVANTAGES OF LOW-E TRIPLE GLAZING UNITS:
- High heat insulation, reduces heating costs.
- Solar energy utilization - 63%.
- Suotable for Passive House.
- High sound insulation.
- Particularly high light penetrability - 79%.
- Does not change color of passing and reflected light.
The maximum heat insulation is achieved in triple glazing units with two selective glasses, uPVC thermal frames between the glass 14, 16, 18, 20 mm. Glass units filled with argon gas. Such glazing units achieve a very good thermal performance with U=0.5 W/m2K. The warmer glazing units you choose, the lower are the energy loss and the lower are the heating costs.
Double glazing units contains 2 glass joined together with aluminum or uPVC frame. KS selective glass (glass is covered with a special coating that keeps the heat) to further improve the thermal characteristics of the glass. Heat-saving glass units contains selective glass, filled with argon gas.
The heat transfer coefficient U of double glazing with selective glass can vary from 1.0 W/m2K to 1.7 W/m2K.
The heat transfer coefficient U of double glazing without the selective glass is 2.7 W/m2K.
