Triple or Quadruple Pane Windows
Bit by bit, we are being persuaded to shift from double to triple glazing as we are all interested in improving the energy performance of our windows. Whether you’re planning to replace the windows in your existing home, adding new ones through an extension, or even building from scratch, windows are increasingly becoming more sophisticated. As a matter of fact, quadruple glazing is the next logical step if triple glazing is no longer cutting it.
Having strong, durable and high-quality glazing windows has many benefits especially because it uses materials with more energy-efficient properties. Good quality windows make it easier to control the overall temperature of the commercial building or home. Spotless glass panes, custom-built to perfection allow passers-by to look directly into your store and choose if they want to step in.
A home that doesn’t have glazed windows emits heat directly through the window. A single pane of glass is a poor insulator as it lets heat straight out the window. Double glazing is comprised of a layer of gas trapped between two panes of glass which allow less heat to be lost through the window.
Glazing a window is one of the best things one can do to maximize the energy-efficiency of your home or building.
Those with single glazed window panes notice how hot their rooms become during summer and colder during winter. It’s even so easy for noise from outside to penetrate and break the glass. But even though double glazing has greater capabilities to regulate internal temperature and reduce energy expenses when compared to single pane windows, it also comes with its downsides.
The Downsides of Double Glazing Windows
- Poor energy-efficiency – double-pane windows have poor energy efficiency due to its structure and low thermal protection capabilities.
- Cost of Repair – The materials used will determine how expensive it will be due to the increased amount required for the windows. In case the material happens to be Aluminium or vinyl, the maintenance cost may not be that expensive. However, there will still be costs incurred for painting from time to time. If the material is wood, the maintenance costs will significantly increase due to the biodegradable nature of wood. There will also be increased costs in protecting the wood against termites, rodents, moisture and heat.
- Condensation – Sometimes the sealed units in double glazed window panes could be poorly done and cause condensation to appear on the interior side of the window.
- Conductivity – Double glazing is not the best option when it comes to insulation. It is not effective in keeping the temperature inside a house at a stable level because it lets the outside weather influence it.
Double glazed windows used to be the “standard” choice for homeowners until triple glazing windows came into the scene.
Triple Glazing Windows
As you know, the system of triple glazing window is made up of three panes of glass set within a frame separated either by a vacuum or glass-filled-space. Predominantly, that improves the thermal performance of the windows, adds to the acoustic performance and also makes the windows more secure.
With all these benefits, it’s natural to assume that triple glazing is always going to be more suitable than double glazing. However, things are not that simple. The rough and ready method for comparing the performance of windows is the “U-value” measurement.
Every window – single, double, triple or quadruple – has a Window Efficiency Rating (WER). There are usually three factors that are tested. They include:
- Effective Air Leakage (L factor) – this is the base of a quality window. Air leaking in causes cold draughts and air escaping means heat loss. Therefore, you’ll be spending more on your energy bills to compensate. The lower the L factor, the better the window and frame perform against air leakage. Ideally, you’re looking for a value of 0.00 W/m2.K
- Thermal Transmittance (U Window) – similar to the air leakage test, this measure how good a window is at preventing heat from escaping inside. The lower the transmittance, U value, the less heat can be lost through the window. The ideal value would be 1.00 W/m2.K
- Solar Factor (G Window) – when sunlight passes through a window, heat in the house will increase. This is known as solar gain. A window with a high solar gain will be effective in allowing heat from the sun into your home. This can be handy during winter months.
The combination of these three factors provides you with the energy index Rating.
Pros of Triple Pane Windows
- Triple plane windows have a lower U-value, making them more energy efficient
- Triple glazing windows can keep the cold out and stop heat from escaping your house during winter
- The extra pane of glass makes it a better insulator, therefore, it can prevent heat from getting in during summer
- Triple glazing windows keep noise out, hence, adding value to your property
- Triple pane windows are safer and stronger as they are more rigid than regular windows
Cons of Triple Glazing Windows
- The higher initial cost of triple plane windows when compared to cheaper double glazed option
- Require additional work during installation process
Quadruple Pane Windows
Triple glazing windows recently used to be the most notable new innovation. This was up until the new quadruple pane windows made a mark. Quadruple pane windows are the most advanced type of windowpane right now. It is basically four high-performance glass panes set to revolutionise the window industry.
Pros of Quadruple Glazing Windows
- Provides more efficiency than a house wall and gives off a ‘U’ value of 0.4W/m2.K
- Quadruple glazing windows make the insulation better by using four sheets of windowpane glass with three spaces filled with airtight gas
- Helps prevent condensation on your windows especially during winter
- Improves security and durability
- Helps block outside noise due to the creation of the tight seal
- Reduction in the structure’s carbon footprint
- Minimal re-tooling is required during the installation of current sections
- In some conditions, it can be retro-fitted to existing frame
Cons of Quadruple Glazing Windows
- Quadruple pane windows are quite expensive
- Quadruple pane windows are also heavy and require tougher, more durable window frame and sash
- It can be harder to install large quadruple glazed windows due to their weight
Triple VS Quadruple Window Glazing – Which One Is Better?
Now that we know the triple pane windows offer two layers of insulation and quadruple pane windows offer three, how effective either of them is highly depends on the area one lives in.
There are some technical problems when it comes to adding more and more panes of glass. In fact, quadruple glazing windows can reduce energy efficiency as the amount of sunlight the window can absorb is reduced.
However, when it gets down to the two, quadruple glazing windows are the best and portray great thermal qualities. Besides, various tests have concluded that they are effective at keeping out the cold just like a standard house wall! In the long-run, installing a window system with energy efficiency means that one gets to save a lot of money on their heating bills during its entire operation.
