What’s the influence of aluminum spacer for insulated glass?

Insulated glass is consisted of two or more glass panel, which is seal by glazing tape with high strength and high air tightness composite adhesive around. In order to make sure the air dry degree of each glass panel, we filled with the dry gas in the aluminum spacer as the desicant. We can choose different kinds of glass according to customer’s requirement. For example: colorless transparent float glass embossed glass, heat-absorbing glass, reflective glass, laminated glass, tempered glass, Low E glass etc. The thickness of glass such as 3、4、5、6、8、10、12mm and thickness of spacer like 6、9、12mm.



To design the perfect insulated glass with suitable aluminum spacer is very important. The reason is that the thickness of the spacer will be affect the energy transfer. It can reduce the energy transfer by the radiation form, thereby reducing the energy loss.

Convective transfer is causing by temperature difference between two sides of the glass. Causing the air to fall on the cold side and rise on the hot side. All these resulting in air convection and the loss of energy. Maybe at this moment, you will ask why everything happen like this? The answer is the aluminum spacer.Here talking about three main reasons:

1.Glass and the surrounding frame system of poor sealing, resulting gas can be directly exchanged to produce convection in inside and outside, making the energy loss.
2.The unreasonable design of the aluminum spacer for the insulated glass, which makes the interior gas convective because of the temperature difference.Therefore, it’s driven by energy exchange, resulting in the loss of energy.
3.The temperature difference between inside and outside of the window constituting the whole system is large. Air with cold radiation and heat conduction

In a word, The thickness of the aluminum spacer play an important role for the insulated glass. Even thought it can affect the function of the insulated glass. When we choosing the insulated glass for windows, doors, partition wall etc. We should  looking for the professional glass manufacturer to make sure the insulated glass is perfect design and work well.
