Double Glazing: What You Need to Know
Double Glazing is the most effective way to combat cold air infiltration into a building and is often described as “enforced air” because it requires an air gap between the panes. Insulated glass generally consists of two or at most three glass window panes interconnected by a sealed gas or vacuum in order to prevent heat transfer through part of the building envelope during cold winter months. Double glazing is an effective measure against heat loss, because it is capable of stopping the warm air from leaking out of a building and into the environment, while at the same time keeping in cool air from inside. Even if an uninsulated building doesn’t have double glazed windows, it is still recommended that high quality double glazing be installed if possible.
With double glazing, you not only have energy efficient windows, but you also have windows that are exceptionally durable and secure. Because the seal is tight, you don’t need to replace windows that become damaged or have a leak because they are sealed tightly. If you have older, drafty windows, they can still be opened if the seal is broken, but new windows with seal protection would be better. Windows with double glazing can add as much as 25% to the value of your home, depending on the number of windows and square footage.
In order to install double glazing properly, it is recommended that you use a Double Glazing Evesham company such as https://www.firmfix.co.uk/. This is a metal ring with a lip around it that fits snugly into the upper part of the window. Because the windows are so tightly sealed, any air gap in the insulating layer will cause a leakage through the spacer bar and into the room. In order to maintain the proper air pressure and prevent a leak, the spacer bar must be adjusted properly. If it is not adjusted properly, the seal will not be as effective and the value of your home could be decreased significantly. The cost of the insulating layer alone can be several thousand dollars, depending on how much the property is worth.
