When it comes to building or renovating a home, you will confront a decision to make as to whether to purchase a single or double glazed windows. Many people believe that investing in double glazed windows offer better insulation properties than the standard windows. They are expensive as well. But once you know how they work and how effective they are, they may seem like a worthy investment. Read on to know more.
What are double glazed windows?
Double glazing is a window or a door that bears two glass panes installed in its frame rather than one. But, its energy efficiency isn’t derived from its extra thickness but from the gap created by the glass panes. The empty space between the panes offers insulation from heat and cold. The significance of insulating glass cannot be overestimated.
How Do Double Glazed Windows Work?
The key to effective working of double glazed windows is the gap or space between the two glass panes that makes it a double glaze window. The trapped air or gas in this space delivers three important functions:
- It acts as an insulator, helps in reducing the permeating of hot or cold air inside and outside the house.
- Double glazing assists in preventing the condensation from occurring from the internal of the house when it is cold outside and warm inside.
- It helps in reducing the noise pollution by eliminating the ability of external noise through your windows and into your home.
While they have a knack to act as an insulator from hot air temperatures, they don’t offer insulation from the radiant heat. To help in reducing this, a special ultraviolet or UV light blocking window tinting is needed. This works better on both single and double glazed windows.
Not All Double Glazed Windows Are Same
What is inside the gap between the window panes makes all the difference in their efficiency. Standard windows tend to trap the natural air between the window panes. This is proven to be quite effective, but the alternative to double glazed windows are effective too.
- When the gap is filled with nitrogen gas, it increases the insulation properties.
- Argon gas can also be used as it is used while manufacturing the double glazed windows.
- The laminated glass window has a thin plastic membrane packed between the two glass panes. This is usually utilized in the commercial structures but can also be used in residential buildings as well and have a greater insulation and being shatterproof at the same time.
- Thermal glass also consists of a thin membrane which is particularly designed to cut down on the UV radiation and keep the radiant heat at bay from passing through. This kind of glass is typically used in for making skylights. Your choice of windows should be made on the basis of the amount of the insulation you need and whether or not your windows should be exposed to the direct sunlight.
If a part of problem is the heat coming from the direct sunlight, opt for installing awnings apart from the double glazing windows to increase their effectiveness to paramount. If this is not possible to implement, go for tinted or thermal glass.
