Which One to Choose - Triple Glazing or Double Glazing

Those who have been hoping to upgrade their conservatory in order to enjoy unsurpassed levels of comfort and efficiency will often look to the experts at Elephant Windows. Boasting more than 35 years of experience in regards to windows, doors and conservatories, our technicians offer the flexibility to tackle nearly any project imaginable. One of our specialties involves replacing an existing conservatory roof in favour of a new design in order to lessen energy costs over time as well as to reduce exterior noise pollution. This is when a system known as triple glazing will often come into play. However, what is the difference between double and triple glazing? Are the associated benefits worth the transition? Let us first examine the science behind this technology before moving on to highlight some of the many benefits which customers can expect to enjoy.

Triple Glazing vs Double Glazing: The Main Takeaway Points

The main principle behind either of these variants is the presence of a gas between sealed panes of glass. This gas acts as an effective thermal insulator; enabling rooms to remain cooler in the summer and warmer in the winter in regards to exterior temperatures. As the name already denotes, triple glazing adds a third layer (pane of glass) to the system whereas double-glazed windows consists of only two panes. This unique design feature is one of the most thermally efficient configurations currently on the market. So, why could a triple-glazed conservatory roof represent an excellent option? Let us take a look at some professional observations to learn more.

Staving Off the Cold Winter Weather

Double- and triple-glazed window systems utilise a non-reactive gas (such as nitrogen or argon) permanently sealed between their panes. The main takeaway point here is that the gas represents an effective barrier against heat transfer. When we translate this into a conservatory environment, energy savings are enhanced. Let us also take into account the fact that the majority of heat will often be lost through the roof of a conservatory.

Thus, it only makes sense that triple-glazed windows will offer superior levels of insulation when the temperatures outside begin to drop. This is only one of the advantages which homeowners can expect to enjoy when opting for triple glazing.

The Principle of Solar Gain in the Summer Months

We should also quickly mention a concept known as "solar gain". Solar gain signifies how much warmth a room will experience due to the radiation from the sun. This is important during the colder months of the year, as higher levels of solar gain will help to reduce heating costs. The solar gain associated with double-glazed conservatory roofs is roughly 62 per cent. Triple-glazed variants absorb slightly less; 50 per cent on average. However, it is important to note that specific coatings which can be added to the glazing will be able to return this value to the aforementioned 62 per cent. In other words, you can enjoy superior levels of thermal insulation while still maximising the amount of solar gain within a conservatory.

Undeniable Acoustic Advantages

One interesting feature of triple-glazed roofs and windows is that the presence of gas between their panes also acts as a potent barrier against exterior noise pollution. This can be a very real concern if you live near a noisy urban centre or close to a motorway. When we consider the sheer dimensions of the average conservatory roof, leveraging this type of acoustic insulation is wise if you hope to fully enjoy all that your structure has to offer.

Increased Structural Stability

A final benefit associated with triple glazing involves its inherent strength due to the presence of a third pane. These windows will be much more difficult to break; offering an additional level of security. This is also important in terms of conservatory roofs, as any branches or tree limbs are less likely to cause damage when compared to standard double glazing.

This is perhaps one of the main reasons why 80 percent of the windows sold throughout Europe now contain three panes of glass.

Additional Considerations

In terms of triple glazing vs double glazing, cost will need to be taken into account. The same holds true in regards to selecting the right glass thickness as well as the cavity between panes. These will be addressed by the professionals at Elephant Windows so that the most suitable configuration can be selected. The good news is that the slightly increased cost of these windows will normally be offset by the amount of savings you will enjoy on heating costs over time.
