Insulating glass is made by two or more than two sheets. The space between the glasses is field with air or other special gases and sealed with sealants.

  Fine performance

Insulating glass is made by separating two or more pieces of glasses with effective support and well-proportioned partition, and felting and pressurizing their edges with dry gas space between the glass layers. Insulating Glass usually has single-cavity and double-cavity structures.

1.Energy conservation heat preservation and heat insulation

The heat insulation of Insulating Glass is the more satisfying one among all the present deep processed glass products. Especially,  the application of LOW-E Glass. inertgas filling and warm edge technology makes the heat insulation of Insulating Glass reach its optimization.

2.Comfortableness Sound insulation and noise reduction

nsulating Glass is the ideal material for sound insulation and noise reduction and can effectively reduce the sound level in a large range. Under the obstruction of Insulating Glass, all kinds of noises can be steadily reduced by more than 30db,Another 5db can be reduced further if inert gases have been filled in.

3.Environmental protection Low Temperature but No dew

The most fulsome trouble caused by window glass must be the dew on the surface of the glass in high latitude zones. The wet window frame is the perfect bed for bacteria breeding. This will not only bring visual uncomfortableness  but also will even be the inducement for people’s sickness in winter. The sufficient quantity of desiccant filled in the spacer strips of Insulating Glass can effectively absorb the water vapor in the air cavity, including that infiltrated from the outside, The heat insulation of insulating glass successfully solve the problem of dew on the inner layer of glass and make the indoor glass surface get rid of dew so that the trouble puzzling people has been eliminated.

4. beautiful-clear and penetrated:

Different kinds of original glass pieces are used to compound Insulating Glass, The visible light transmission ratio can be adjusted from 12% to 80%. The reflectivity can be kept within 13-15%. Take the compounded Insulating Double Silver Coating LOW-E Glass with E value of 0.04 for example, after inert gases have been filled in, its U value can reach 1.3 and even 1.1 That equals to the heat preservation and heat insulation performance of a 370mm thick brick wall. That this kind of Insulating Glass is widely used can not only beautify the buildings, increase daylighting areas and save energy, but also partly replace brick walls or concrete walls and lighten the load bearing of buildings.

Insulation glass synthetic materal spacer layer

The thickness of commonly used insulating Glass is 6mm,9mm, 12mm or 15mm,The thickness of the gas spacer layer influences the thermal resistance value of insulating units, With the same glass quality and the same seal structure, the thicker the spacer layer is, the higher the thermal resistance value is. But when the thickness of the gas layer reaches a certain degree, the increase rate of the thermal resistance will be very little, The reason is: After the thickness of the gas layer reaches a certain degree, because of the temperature difference of the gases in the glass, convection and sped-up heat transmission will happen so that heat insulation will be weakened, Experiments proved that by insulating and compounding glasses with a thickness of 6mm,
There will the increase of the thickness of gas layer if it is over 13mm. Inside the insulating Glass, besides dry air, inert gases like argon gas and krypton gas can be filled to decrease K value by 0.1-0.2. Whichever kind of gas is filled in, with the same thickness, basically, the SHGC value and visible transmission ratio of Insulating Glass keeps unchanged.

Desiccant

In order to realize real heat preservation, sound insulation, dust removal, energy conservation and useable life-span extension of Insulating Glass, the correct choice and use of desiccant is very important, The chosen desiccant should absorb water only rather than other substances; its absorbing performance should be ≥19%,but the absorbing speed should not be too high; its anti-pressure intensity should be%20N,etc.
3A molecular sieves are more applicable to be the desiccant of gas-filled insulating glass. Usually the dosage should be controlled  around 110g/m2

Sealant

The compounding method of sealant has long been the focus. Actually, every kind of seal structure and sealant compound has its excellent applications. Regarding specific selection, one should know the quality and characteristic of every kind of sealant, the structure of insulating glass, different applicable part, installation method and structure, different applicable zones, environment and climate, etc. the solutions should be confirmed after comprehensive analysis.

 

Sealant depth:

 

In the GB/T11944-2002 Insulating Glass standard, the hypo-sealant depth ranges from 5mm to 7mm. But for frame-hidden curtain wall, the particularity of the structure determines the security caused by the insulating glass Units(IGU) under load bearing, The sealant must be silicone structure sealant and the seam must accord with the safety load design, Under normal conditions, the seam of structure sealant should not be less than 6mm,but not more than the thickness of spacer layer of insulating glass. when the spacer layer is over 12mm, the sealant depth should not be over 13mm, For structure sealant, it is not the deeper, the better.

 

Application scope

 

The insulating glass has a fine performance of heat and sound insulating and much lighter comparing with the brick wall and concrete wall. To meet the requirement of energy saving the building should has, the insulating glass has been widely used in hotel, restaurant,  airport, hospital, lab; and instruments, electronic, broadcast, TV, where the constant temperature and moisture, sound and heat insulating are need, also including the luxury houses, food cubicle, refrigerator and so on.
