Double and Triple Glazing

Difference Between Double Glazing And Triple Glazing

When planning window upgrades, it's only natural to wonder whether to choose double or triple glazing. 

The only difference is that double glazed windows have two panes of glass, whereas there are three glass panes in triple glazing. 

However, despite having only one significant difference, both present a unique set of advantages and disadvantages that should be studied thoroughly before either is selected. Think about how energy efficient they are and which one's better at insulating the house, for starters. 

The two (or three) panes can also be made of decorative glass to create windows that look good in any setting. They may also be covered with window films that add to the insulation and protects from sunlight. However, despite being aesthetically pleasing, these windows can still be a barrier between the inside and outside of the house.

Gases like krypton, xenon, or argon are commonly used to fill the space between the panes and keep the heat or cold inside from escaping outside. 

Let's study each type and its pros and cons.

Double Glazing

Here are the advantages:

• It could be less expensive than triple glazing windows
• They can decrease the heat loss
• They are excellent at keeping the noise away from the houses, making them suitable for homes in noisy or congested locations

The drawbacks:

• They are inefficient in terms of energy efficiency when compared to single or triple glazing
• Double glazed windows are less secure than triple glazed windows
• The third panel gives an extra coat of protection. Unfortunately, they do not have the same longevity as the triple glazing windows

Triple Glazing

To begin, let's look into the advantages:

• They provide excellent sound insulation — far better than double glazing
• Longevity and durability (triple glazed windows can last up to 30 years!)
• Owing to the additional layer of glazing, it is more secure against break-ins
• Has a low U-value (Learn more about U-values)
• They are incredibly energy-efficient and can help save money on the utility bills

Now, get familiar with the drawbacks:

• Installation costs can be higher than for double glazing
• Due to the additional layer, it is significantly heavier than single or double glazing

Are Double or Triple-Glazed UPVC Windows A Good Option?

For a variety of reasons, UPVC windows are extremely popular. The material used in the UPVC double glazing windows, in particular, is quite adaptable.

Here are several reasons why people should opt for the UPVC Windows:

• It is steady, which means that it can withstand the rain and wind without being harmed

• It's long-lasting, so it will last for years to come
• UPVC comes in a variety of colours to complement the households
• It is relatively inexpensive, as compared to others
• It's pretty simple to keep up with and clean
• There are numerous window styles to choose from
• With double glazing, it works perfectly

Benefits Of Double & Triple Glazing

Let's study some benefits that double glazed windows and triple glazed windows offer.

Energy Efficiency

Among the most compelling reasons to upgrade to double glazed glass from a single pane is the greater energy efficiency that comes from the extra panel of safety glass.

Hence, it is understandable that triple-glazed windows improve energy efficiency even more. However, because windows lose almost one-third of a home's heat, it's critical to maximize insulation and decrease the heat levels considerably.

The U-value is used to calculate how much heat a house loses. Single glazing usually has a U-value average of 5.8, double glazing has an average of 2.9, and triple glazing has an average of 0.9. It's a no-brainer.

The additional panel of frosted glass aids with reducing heat loss. The extra air gap also helps with a passive gas like krypton argon to maintain delightful warmness in the households.

It's important to realize that replacing the windows to conserve energy is just one of the many factors. So, also make sure to insulate the doors, roof spaces, and floors.

Noise Reduction

Replacement windows will significantly reduce noise levels if anyone resides in a loud area or a heavy traffic road.

While double glazing might aid in reducing noise, one can get even better results with triple glaze. However, keep the following in mind:

• The thickness of the tempered glass determines sound insulation. Noise can be further reduced by selecting diverse combinations of windowpane thickness, as every level of glass thickness will bring about an altered sound frequency. The change in thickness should ideally be around 35% for the most remarkable effects
• The distance between the panels is also significant because the more extensive the gap is, the better the noise suppression will be
• If someone utilizes trickle ventilators on the windows, the drop in noise one has accomplished will be ruined

When deciding between triple and double glazing, it's a good idea to consult a professional about the specific scenario and the noise problem.

While triple glazing tends to be more valuable in many aspects, it is also more expensive.

Cost Comparison

There is always some cost implication when comparing products. But, as people might guess, triple glazing is the more expensive alternative because it relies on more costly manufacturing procedures and contains more raw ingredients.

One should, in all likelihood, get a return on investment for the money spent on double glazing or triple glazing with the lower heat bills and lower expenses for the future.

Triple glazing is the right option for anyone who wants the highest comfort and energy efficiency from their windows.
