Double glazing, also known as insulating double glazing, consists of two or three panes of glass separated by a layer of air-filled or gas-filled cavity to reduce internal heat transfer over a certain area of the structure envelope. By increasing the thermal resistance between the panes, the temperature inside your house can be kept at a steady state, keeping you comfortable year-round. Some of you may require pvc over aluminium and that’s fine , so the Doorwins upvc department in London are based here .
The heat loss within your house is usually caused by the ventilation process. If you do not have proper ventilation, then the warm air outside the house will be absorbed by the walls, causing them to expand and contract. This causes the room to heat up and cool down, depending on the season. For example, during winter the insulating properties of your walls to prevent heat from escaping outwards, which keeps the rooms inside the house warm.
However, if your ventilation is blocked or poorly ventilated, the inside of your house will get too cold and not allow the cold air to escape through the air-filled cavity, causing the walls to freeze. In order to prevent this, the glazing is fitted over a cavity filled with gas, which acts as an insulator.
The gas fills the cavity with a refrigerant, which acts to keep the temperature constant inside the house. A refrigerant in the gas-filled cavity allows heat to escape at the same rate as cold air, keeping the inside of the house warm and the outside cool. The air-filled cavity also prevents heat loss into other areas of the house, improving the insulation between the wall and other structures.
