Insulated glass units or double glazed multiple planes are made by combining multiple glass planes. They are either made using two (double glazing) or three (triple glazing) panes. The different panes are usually separated by a layer of gas and a spacer. They are increasingly becoming more popular in the modern days due to the rising cost of energy. They are fitted with wider windows. The space between glass panes is meant for increasing the insulation to prevent heat loss.
Preventing heat loss is an effective method of keeping the house warm in winter. They are also used in preventing unwanted heat that would increase the indoor temperatures thereby eliminating the need for air conditioners and artificial heaters. In addition to this, they are also effective in reducing the noise levels. Increasing the gap between the two panes is also useful in improving sound reduction.
Typically, the space between the glass ranges from 6-20 mm. The optimum space for improving the thermal performance is 12mm. A 15 mm space is recommended for reducing low-frequency noise. Large gaps are known for increasing the rate of convection. This, in turn, reduces the insulating performance. To improve the energy efficiency, you are advised to use a double glazing having a space of 10-20 mm.
What is in between the gall planes?
The space between the glass planes should be fully sealed. This space is meant to increase the level insulation thereby preventing heat loss from the building. The gas filling this space is also useful in increasing acoustic and thermal performance. The gas used should have conductivity properties. The commonly used gas is argon. A spacer is also included for removing any moisture that might be trapped within the airspace.
Laminate and low-e glasses are the main types of glass used in making the double glazing units. They are known for being effective in controlling noise and increasing energy efficiency. Additionally, low-e glass is helpful in reducing heat loss and disrupting sound waves. This has made it ideal for improving the acoustic performance.
- Improved home security: manual locks and security systems can be incorporated into these windows and
- doors to provide extra security.
- Maintenance: Little maintenance is required.
- Saving money: They are effective in lowering energy consumption.
- Reducing noise pollution
- Heat cannot flow easily across the window
- Costly: The acquisition cost is very high, but they will help you in saving cost in the long run
