Double Glazing Glass

Double Glazing Glass

Insulated glass units(I.G.U.), also known as double glazing units (or double-pane, and increasingly triple glazing/pane) is made of two or more pieces of glass sheets separated by aluminum frame filled with molecular sieve ( desiccant ). The frame is stuck and sealed by butyl glue on the glass surfaces and Thiokol or silica gel seals all outside edges. Filling gas inside the glass cavity can strengthen its sound and heat insulation properties efficiently. Laminated or tempered glass may also be used as part of IGU.

Product Details

Double glazing glass windows consist of two layers of glass with a layer of inert gas sealed between them. This creates nearly twice the insulation as single glazed units. Once sealed, the unit becomes airtight.


The advantages of double glazing glass windows are:

Energy cost saving.The airtight construction of double glazed windows creates thermal insulation. This reduces the flow of incoming and outgoing heat. Less energy is used to heat up or cool down the space, resulting in lower energy bills.

Adding a third or fourth layer of glass increases the insulation value of your window. Each layer of glass traps a significant amount of heat that passes through, increasing the windows protection against heat loss.




Double Glazing Glass Characteristics
1)  Energy Saving: good heat insulation property, heat transfer coefficient is much lower than single glass  when insulated glass is used in air conditioning and heating environment. I.G.U. is the ultimate
solution which can save substantial amounts of money in the monthly bills.
2) Sound Insulation: Windows installed with insulated glass are well insulated from any noise, can     deaden outside noises into indoors through windows.
3) Anti dewing. The dry air inside the enclosure protect the I.G surface from dewing  when        circumstanced a big temperature difference between indoors and outdoors.
4) Excellent UV filtering function effectively lower the UV radiation effects on the indoor furniture and home appliances.


TSING GLASS provides the following 5 types of insulating glass units for windows:
1. Double Pane Insulating GlassThe most common insulating glass unit is constructed with two plies of glass and one sealed air space. This configuration is a dual pane or double pane insulating glass unit, however is commonly shortened to insulating glass.
Insulating glass is used due to the improvement in solar performance it provides. The most significant improvement is thermal performance (u-value) which improves by approximately 50% when compared to a monolithic glass ply. This improvement occurs whether the glass is coated or uncoated.

2. Insulating Laminated Glass Insulating Laminated Glass provides the solar controlling properties of an insulating unit along with the safety features of the laminated inboard component. In addition, Insulating Laminated Glass enhances acoustical performance, ultraviolet light protection, and the laminated component is designed to remain integral in the opening should glass damage occur. For this reason, insulating laminated glass is utilized for skylights or other overhead glazing applications.

3. Laminated Insulating Glass Laminated insulating glass is an insulating glass unit with a laminated outboard. This configuration can be used in applications where the exterior is overhead glazing or in specific hurricane zones where safety glazing is required for the exterior. As for Low-E or Reflective coating placement within the unit, please consult the salespersons.

4. Double Laminated Insulating Glass  Double laminated insulating glass units have both a laminated inboard and laminated outboard with a space in between. This configuration is often selected when improved OITC acoustic performance is desired such as in schools. In addition, double laminated insulating units can meet protective glazing requirements.
As for Low-E or Reflective coating placement within the unit, please consult the salespersons.

5. Triple Insulating GlassThe most common triple insulating glass units are constructed with three plies of glass separated by two hermetically sealed and dehydrated spaces. This construction increases the insulating value of the glass unit, thus reducing the u-value. A triple insulating glass unit is especially useful in applications where a low u-value is necessary. More commonly, triple insulating glass units are constructed with three plies of 1/4" glass and two 1/2" spaces.
