Windows probably is the most taken for granted part of the house. Even though they serve quite a lot of purposes, many tend to keep windows and their maintenances at a bay.
It is always important to ensure that your windows are not only properly maintained, but also beautiful to look at. In that case, Double glazed windows are a perfect choice, especially when you aspire to have beautiful windows that also keep the house cozy and warm.
If you are new to the concept of double glazing windows, here, you will understand everything that you need to know about double glazed windows and what are the benefits of using such windows.
What Exactly is Double Glazing?
Just as the name suggests, double glazing is a form of door or window that contains two glass panes instead of one within the frame. Interestingly, the efficiency of these windows does not come from its extra thickness, rather, from the gap that is present between each pane. This empty space offers optimal insulation from cold and heat waves.
One cannot simply deny the need for insulating glass for commercial and residential properties. Several studies reveal that windows remain responsible for heat gain or loss in a room. Here are a few things to look at:
- During winters, heat loss which occurs only through windows will be 10 times more than an insulated wall. On average, this can account to over 40 percent of heat loss in a typical household.
- During summers, heat gain is amplified to over 100 times when you have un-shaded windows in your home. Put it simply, a square meter of single or the traditional glass pane windows would produce heat equivalent to bar radiator.
Heat Gain and Heat Loss in Double Glazed Windows
The rate at which conduction of heat occurs is calculated in U-Values. For glass pane having the thickness of 3mm, the U-Value would be about 5.9. On the contrary, two glass panes having a thickness of 3mm and 6mm respectively with a gap in-between come with U-Values of 3.1. It means the addition of another glass pane decreases conduction of heat to about 50% roughly.
The frame of double glazed windows also brings a significant difference to the overall U-Value. A conventional aluminum frame would have U-Value of about 6 to 10, based on the grade that you choose, while timber frame is rated at only 2.8.
Now, loss of heat is measured in terms of R-Value, which is basically the ability to prevent or resist heat from moving outdoors. In winters, the R-Value matters a lot. Therefore, simply by opting for double glazed windows with the desired R-Value you not only save energy loss but at the same time reduce your utility bills too.
Apart from the material, there are other factors that affect heat gain and heat loss in a double-glazed window and these include:
- The argon gas present in between the panes of double-glazed windows takes its thermal efficiency of the window to the next level.
- There are several manufacturers out there that have come up with aluminum framed windows with exceptional U-Values
- Counting on a reliable professional for installation is also essential, as this determines whether you will be able to harness the properties of the window or not.
When you want to renovate your existing home or are building a new one, do not forget to uplift its efficiency with high-quality double glazed windows. By selecting this technology, you get a guarantee that your home will stay pleasant and efficient for generations. They are indeed a great investment which can minimize your carbon footprint and save a lot of money.
