Benefits of Double Glazing

The are many benefits of double glazing your doors and windows. However, how exactly do the double glazing units work? How do they prevent heat from escaping your house and cold air from getting inside?

Aside from the roof, windows are the quickest way for heat to leave your home. While most of us desire airy and light homes, there is always a price to pay for having so much glass, such as, high energy bills as well as a colder home.


Double glazing reduces heat loss in a house through the following ways:

Temperature Control

The impressive insulation attributes of double glazing usually work in two ways. Firstly, it makes your house warm during winter. Secondly, in the summer, you experience a cooler home.


The insulating layer of gas or air inside your window unit dramatically reduces heat transfer from the warm air outside. The gap between the outside pane of glass and the inside pane of glass is the key design feature in maintaining temperature control inside your home. The window cavity itself does not need to be sealed, just as long as the space is maintained between inside and outside, the window shall continue to be thermally efficient.

Improved Insulation

The gas or air inside your double glazing unit normally acts as an insulator. While this does not prevent heat from completely escaping, it drastically reduces the amount of heat that’s lost via the windows.


Moreover, since the air gap is narrow, air has less room to efficiently circulate around the unit. What does this mean? It simply means that there is some amount of heat that is lost via convection.


Effective double glazing accounts for around 54% – 64% reduction in heat reduction from the home.


Additional Benefits of Double Glazed Windows


On top of reducing the loss of heat from your house, double glazed windows bring with a number of added benefits. Installing such kind of windows represents a major investment that might feel like a huge outlay for some little real improvement.


The following are some of the other reasons double glazing is a wonderful investment for your house:

1: Makes home more energy efficient

Double-glazing is better in terms of being more efficient compared to regular doors and windows. This goes miles in limiting the amount of heat that is lost which translates to reduced energy consumption. Ultimately, you can be able to enjoy lower heating bills and a warmer home while at the same time mitigating carbon emissions. On top of that, double glazed windows are handy at helping to ensure your home maintains a constant temperature in such a way that you can be able to enjoy comfortable ambient temperature consistently. As mentioned earlier, you’ll enjoy a cooler environment in the summer and warm environment in the winter.

2: Brightens your Home’s Appearance

Although it may feel like upgrades to your kitchen or interior will yield greater aesthetic rewards, it is worth remembering that doors and windows are the first thing that people see immediately they arrive at your home. A variety of double glazing styles for doors and windows are available today to help you perfect the outward appearance of your home.

3: An Easier to Maintain Home

uPVC windows to be specific provide greater ease of maintenance. They don’t need any painting. All you need to do is just wash them down frequently with some warm soapy water to keep your windows feeling and looking fresh for years.

4: A More Secure Home

One of the best attributes about double glazed doors and windows is that they are stronger compared to the conventional single pane windows. Additionally, the frames are more rigid which makes them difficult to break into. On top of protecting your home from forced entry, this can also act as a major deterrent to intruders.

5: A Quieter Home

Double glazing is highly effective at significantly reducing any unwanted noise thus ensuring you can enjoy the desire quietness and peace at home.

6: Reduced Condensation

Condensation occurs when cold air from the outside meets with the hot surface. The air gap that is inside the two panes usually keeps the inside glass of your unit at room temperature hence virtually eliminating the condensation. Does your home constantly experience condensation issues? If yes, then you should consider double glazing as it might really help reduce it.


Does Condensation Inside my Window mean It is No Longer Thermally Efficient?


This is an extremely common question we receive at Crystal Clear Window Works.

When a double glazing unit fails, air will enter the window cavity causing condensation to settle on the inside of the glass panes causing that misted, foggy, unsightly view.

With the view and aesthetics of the double glazing unit being compromised, many believe that the window is no longer “working”.

However, as detailed above, the core design of double glazing units and their effective thermal efficiency is the window cavity itself; the distance between the glass on the outside and the glass on the inside.

Even though external air has entered the window cavity and the condensation has formed, the unit is still working as expected. Keeping heat inside of your home and ensuring the cold stays out.
