How Double Glazing Works to Enhance Energy Efficiency
Double Glazing refers to the manufacturing of windows in such a way that they are able to keep heat within an insulated room whilst also reducing the amount of noise from outside by controlling the entry and exit times. Insulated glass is made up of two or more individually sealed glass panes divided by a tight or sealed gas-filled cavity so as to prevent heat transfer from passing through a particular part of the structure envelope.
Insulation is achieved by sandwiching a solid block of wax in between two panes of glass, thus creating an air-tight seal. The most effective method of insulating is using a thick, tightly framed double glazing unit fitted in the wall. This is sometimes combined with air-tight insulation and weather stripping between the panes, which is then fixed to the frame. A Double Glazing Worcester company such as Firmfix can talk you through the multiple benefits of using this type of glazing.
Insulation works by allowing cold air from outside to enter through the window opening but allowing warm air from inside the house to pass through the spacer bars. A special type of double glazing called an air gap is used as an insulating gas by driving in air from the top of the window opening via a gas pipe. The air gap is then filled with a cold gas such as argon, krypton, or xenon. The result is a thicker, higher quality gas than the surrounding air, which behaves like a blanket around the glass panes. The thicker, warmer layer acts like a thermos-like device that helps maintain temperature at all times, even during intense heat waves. An example of an open air gap unit is an aluminium spacer bar.
