Double-glazing your windows can be a great way to insulate your home so that your heating and cooling systems work better. You can save a significant amount of energy that will reflect on your energy bills. However when you purchase the glass for your window,
you need to look out for a few things.
But first, how does double-glazing work?
Double-glazed windows have two sheets of glass with a gap of a few millimeters in between them. The air that is trapped in between the two layers is what prevents some of the heat that has entered your home, from leaving. Otherwise, your windows can be significant source of heat loss through the glass as well as by leakage.
Sometimes the gap in between may also be filled with highly insulating inert gases such as xenon, argon etc.
Things to look for in the glass
1. Now, the kind of glass that you buy will decide how much energy you save. Glass with the ability to let in heat but trap it so that it doesn't escape is available. This kind of glass has low powers of emission. These will be graded as Low-E for 'low emissivity'. That is the kind of glass you need to buy.
2. Check to see that the pacers that are placed between the two layers of the glass are not made of metal.
3. Many manufacturers grade their windows with energy ratings. These are usually from A to G. This rating takes into account the overall energy-efficiency of the window. If you are installing a new window, then you should look for these ratings.
There are several alternatives to double glazing for those who cannot make any constructions on their properties. One way is to use secondary glazing. If you have an existing window, then simply fit a pane of glass on the inside of it. It won't be as effective in insulating your home with a sealed unit, but it will be less costly. It can still save you around 100 pounds of your energy bill annually. Use glass with low emissivity, and it will have better efficiency.
If you are looking for professionals to give your windows a double-glazing, Surrey has many glass contractors who can do the work for you. Remember that it may cost more than a secondary glazing, but that is a one-time cost. In the long run, you will be saving your energy costs.
