Why You Should Have Triple Glazing Windows
Triple-glazed windows have three layers of glass, separated by two air or gas-filled spaces. This design provides much better thermal efficiencies than single or double glazing. This additional layer of glass and air gap between them increases the insulating properties of the windows, offers soundproofing, and saves energy.
Standard triple glazing varies in thickness between 28mm to 44mm, depending on the need. This thickness includes the glass panes and the gaps between them, which are often vacuumed and infilled with gases such as argon or krypton to enhance protection against heat transfer.
Benefits of Choosing Triple Glazing for Windows and Doors
Some advantages of having triple-glazed windows and doors are as follows:
Improved Insulation
The additional layers increase the thickness of the air cavity, making it more efficient in heat retention, regulating indoor air temperatures and minimising energy consumption costs.
Enhanced Noise Reduction
Noise reduction is another advantage; thicker glazed panels provide better soundproofing. This is particularly useful in noisy urban areas or living close to heavily trafficked roads since it helps to minimise the disturbance.
Increased Security
Triple-glazed glass is harder to break than normal glass and thus makes your home more secure.
Comparing Triple Glazing Thickness Options
Here is a quick comparison of common triple-glazing thickness options:
28mm
It has moderate insulating capability and meets most homes’ demand for insulation. It is relatively cheaper, but it does not give the best insulation.
36mm
Has improved insulation and reduced noise levels. It falls under the mid-range category and is well-equipped to handle performance and cost matters.
44mm
It gives the highest thermal performance as compared to other thicknesses. It is suitable for homes in cold or hot environments or regions with much noise but is more costly than others.
How to Choose the Right Triple Glazing Thickness
Selecting the right thickness for your triple-glazing windows depends on several factors:
Climate
Thicker glazing is also beneficial for cold areas, as it helps to save money on heating as it is better insulated.
Noise Levels
The thicker glass will help minimise the noise from the outside, especially if your home is located in a noisy area.
Window Frames
Check whether the frame of the old windows can fit these thicker units. Some older frames may require some modification or even replacement to bear the extra load or size associated with triple-glazed windows.
Budget
It is, however, important to note that thicker glazing units are better, but they will cost more than the thinner ones. Before you plan an installation or purchase, fix your budget and needs, and select glass which meets both.
Triple Glazing vs Double Glazing- Which one is better?
When considering window upgrades, the choice between double glazing and triple glazing is pivotal for enhancing your home’s energy efficiency, comfort, and security. Both options offer significant benefits, but their suitability depends on various factors such as climate, budget, and specific needs. Here’s a detailed comparison to help you decide which glazing option is better for your home.
Energy Efficiency
According to the Energy Saving Trust, upgrading from single to double glazing can cut energy bills by approximately £115 a year in an average semi-detached home. With triple glazing, these savings can be even higher, although the exact amount depends on various factors including the quality of the windows and the existing insulation of your home.
Sound Insulation
Triple glazing offers better sound insulation compared to double glazing. The additional glass pane and gas layer help to dampen external noise, making it an excellent choice for homes in noisy areas, such as near busy roads or airports. For urban dwellers or those sensitive to noise, triple glazing can significantly enhance indoor comfort by reducing unwanted sound intrusion.
Condensation
Condensation on windows can be a persistent problem, leading to mould and damage to window frames. Triple glazing reduces the likelihood of condensation forming on the inside of the windows because the inner pane remains warmer than with double glazing. This helps maintain a healthier indoor environment and prolongs the lifespan of your windows.
Cost Considerations
The cost of triple glazing is higher than double glazing, typically by around 30-50%. This initial outlay may be a deterrent for some homeowners. However, it’s essential to consider the long-term benefits and potential savings on energy bills. Additionally, some government incentives or grants may be available to offset the initial costs, making triple glazing a more viable option.
Security
Both double and triple glazing offer enhanced security compared to single glazing. The additional layers of glass make it more difficult for intruders to break through. Triple glazing provides an extra level of security due to its three panes of glass, making it a more robust barrier against forced entry.
Climate Suitability
Triple glazing is particularly beneficial in colder climates where the additional insulation can make a significant difference in indoor comfort and energy savings. In milder climates, the benefits of triple glazing may not be as pronounced, and double glazing might be sufficiently effective while being more cost-efficient.
Conclusion
Triple-glazing windows are expensive but can be of great value and add value to your home by improving the home’s comfort, security and energy efficiency. Knowledge of thickness in triple glazing is crucial in arriving at a well-informed decision on the glazing to be used. Depending on the type of climate where you live, noise, and window frames one has, the appropriate thickness must be chosen within the set budget.
