Double or Triple Glazed Windows?
When it comes to choosing windows for your home, it’s not just a decision for today; it’s an investment that lasts for decades to come. Double and triple-glazing are two popular choices, each with its advantages. That is why it’s very important to make the right decision between double glazed windows or triple glazed windows. In this post, we will answer the question: What is the difference between double and triple glazed windows? Which is the better option for your home?
Some people are very convinced that triple glazing is a better option than double glazing in every way possible (well it is). Others would argue that choosing triple glazed windows over double glazed windows is not that beneficial. But, who is right? Are triple glazed windows better than double and single glazed windows?
What are the main differences between double glazing and triple glazing?
At the core of the double vs. triple glazing debate lies a simple yet crucial distinction: the number of panes. Double glazing comprises two panes of glass, while triple glazing boasts an additional layer, featuring three panes. The magic, however, lies not just in the numbers but in the meticulous design that enhances the functionality of these glass units.
- Construction and Composition: The panes in both double and triple glazed windows are separated by a warm edge spacer, a critical component that maintains their vertical alignment and optimal distance. This spacer is instrumental in preventing heat loss and condensation, ensuring the longevity and efficiency of the window.
To elevate their insulating properties, the space between the panes is filled with noble gases, typically argon or krypton. These gases are renowned for their excellent insulation, creating a thermal barrier that minimises heat transfer and maximises energy efficiency.
- Tailored Treatments for Diverse Needs: While the panes used in each glazing unit are typically the same, manufacturers have the flexibility to employ various thermal or chemical treatments to meet specific needs. This customization allows for the creation of windows optimised for:
- Heat Retention: Triple glazed windows, with their extra pane, excel in retaining heat, creating a cosy environment while contributing to energy savings.
- Noise Reduction: The additional layer in triple glazing provides enhanced acoustic insulation, making it the preferred choice for those seeking tranquillity in noisy environments.
- Increased Privacy: Strategic treatments on the glass can enhance privacy, turning your home into a sanctuary shielded from prying eyes.
- Heightened Security: Beyond aesthetics, triple glazed windows contribute to home security, acting as a formidable barrier against potential intruders.
Double or Triple Glazed Windows: Are double glazed units enough for your home?
The answer is yes, it may be enough. But, this depends on several factors:
Location and Climate:
The geographical context of your home plays a pivotal role in determining the optimal glazing solution. In areas with milder climates and higher average annual temperatures, double-glazed windows may present a viable choice. The inherent brightness of double glazing, thanks to each pane absorbing some light, contributes to well-lit interiors. Additionally, the windows allow more solar heat to penetrate, leading to faster warming of rooms.
However, in colder climates like the Irish winters, where temperatures demand robust insulation, the advantages of triple glazing come to the forefront. This is especially true for windows that don’t receive ample sunlight during the winter months. The extra layer in triple-glazed units significantly improves heat retention, ensuring a more comfortable living environment and potential savings on heating costs.
New Builds or Renovation:
The stage of your building—whether it’s a new build or undergoing renovation—shapes the feasibility of opting for triple glazing.
In the case of new builds, where modern, energy-efficient materials and technologies are being employed, choosing triple glazing aligns seamlessly with the overall commitment to superior insulation. The long-term benefits, including enhanced living quality and reduced heating expenses, make triple glazing a prudent investment than double glazing.
For older buildings undergoing renovation, the decision becomes more subtle. The depth distinction between double glazing windows and triple glazing units poses a challenge in fitting the latter into existing window openings. However, skilled window fitters like the professionals at JR Fixing Ltd can navigate this hurdle effectively. Relying on their expertise minimises installation costs and eliminates unexpected renovation work, ensuring a smooth integration of triple-glazed windows into your revitalised space.
Double or Triple Glazed Windows: Why choose triple glazing windows over double glazing
Double and triple glazing units may share similarities in terms of glass parameters, but the key distinction lies in the thickness of the glazing unit. The capacity to use thicker units in triple glazing, contingent on the depth of the window frame and the chosen window model, sets the stage for heightened performance and efficiency across crucial dimensions.
1. Heat Retention:
The fundamental principle behind double glazing involves creating an air gap that mitigates the thermal transmission of hot and cold air. Triple glazing takes this concept further by introducing an additional pane and, consequently, another air gap. This amplification of insulation significantly enhances the efficiency of heat retention and solar gain. As a result, triple-glazed windows prove especially advantageous in colder climates, ensuring your home remains warm and energy-efficient.
2. Noise Reduction:
While triple-glazed units can potentially pose challenges in noise reduction due to the middle pane, manufacturers have developed innovative solutions. To optimise sound reduction, specialised laminated layers are added to the glazing unit. These layers, equipped with sound-absorbing films, disrupt sound waves transmitted through the glass, offering a quieter and more peaceful indoor environment. This feature is particularly valuable for homes located in busy urban areas or near noisy thoroughfares.

3. Security:
The added layer of complexity in triple-glazed units, with three glass panes instead of two, inherently enhances security. To further bolster security measures, manufacturers may incorporate laminated glass, featuring a polyvinyl butyral (PVB) layer on the external side of the window. This additional layer toughens the glazing unit, making it more resistant to break-ins. In the unfortunate event of breakage, the laminated glass adheres to the PVB layer, preventing shards from dispersing and maintaining the structural integrity of the window.
4. Laminated Glass for Safety:
Laminated glass, with its PVB layer between two panes, plays a pivotal role in safety. This construction ensures that even if the glass breaks, it remains fused to the layer, preventing dangerous shards from falling. Widely popular in areas prone to mechanical damage, such as skylights or glass ceilings, laminated glass adds an extra layer of protection against potential hazards.
5. Low U Value
Our triple glazed windows boast an impressive U value of 0.74, positioning them as leaders in energy efficiency throughout Ireland. The U value represents the thermal transmittance of a window—simply put, how well it prevents heat from escaping. A lower U value indicates superior insulation and reduced heat loss.
JR Fixing Ltd takes pride in offering triple glazed windows with a U value of 0.74—the lowest in Ireland. This remarkable feat signifies cutting-edge technology and our unwavering commitment to energy efficiency. Homeowners can relish the knowledge that these windows provide an exceptional barrier against temperature extremes, ensuring a cosy and sustainable living environment.
When to Choose Triple Glazing Windows?
Triple-glazed windows are specifically designed for energy-efficient residences, particularly in passive houses, and are highly recommended in contemporary constructions. They demonstrate their effectiveness in various scenarios:
- Homes situated in colder climates.
- Rooms are located in the colder northern part of a house.
- Frequently utilised spaces like living rooms and dining rooms.
- Buildings with numerous or spacious window openings.
Triple-glazed units are expected to be approximately 20 to 30% more energy-efficient (with a U-value of 0.9 W/m2K) compared to double-glazed ones. Nevertheless, several variables can impact the outcome, including:
- Incorrectly spaced gaps between the panes.
- The type of gas or coating used as an insulator.
- The utilisation of a warm edge spacer (composite spacer) within the glazing unit enhances the U-value of the glazing unit.
