Energy Efficient Triple Glazing

Triple glazing isn’t that different from double glazing. In fact, it utilises the same technology. Both double and triple glazing trap argon gas between their panes to prevent heat transfer. Triple glazing is different in that it uses three glazed panes instead of the two used for double glazing. This creates an additional pocket of gas, which equates to even better heat retention and lower utility bills.

Triple glazing is incredibly good at insulation and will make your living space more comfortable all year round. With the increasing costs of living, there is more demand for homes that have triple glazing as they will have lower heating bills.

Triple glazing also makes it more difficult for not only intruders to get into your home, but also for the noise from outside your property.

Frequently Asked Questions

How much is triple glazing?

It is difficult to provide a price for your triple glazing as various factors contribute to the overall costs. The best way to get a price is to call us at 01985 215566.

Will triple glazing really make a difference?

You will notice a considerable difference. It is far more insulative than single or double glazed windows. A brick wall has a U-value of 2.0  W/m²K, a double glazed window has 1.2  W/m²K, and a triple glazed equivalent trumps them all at 0.6  W/m²K. 

You can look forward to great savings on your heating bills, as the interior of your home will retain heat more effectively. 

Should I swap my double glazing for triple glazing?

Bear in mind that triple glazing is more expensive. It’s commonly found in colder areas like Scandinavia where winters are harsher than those in Warminster and the surrounding area.

Switching is worthwhile if your double glazed units are old and underperforming, or if you live in a rural area where temperatures drop sharply during winter nights. However, if you live in a built-up area and your double glazing is new, you won’t see as big a return on your investment.

How long does triple glazing last?

A specific response to this question is tricky without some data. The area you live in, local weather conditions, and how well maintained your windows are will all contribute to the answer.

For your reassurance, our triple glazed windows carry a 10-year manufacturer’s guarantee. In fact, your units will last decades longer if you regularly clear dirt and debris from the frames. Expect yours to work effectively for 20 years, and even up to 35.

How is double glazing different to triple glazing?

Double glazing keeps heat in using two layers of glass that are filled with argon gas. This gas works to prevent cold transfer from pane to pane. 

The same principle applies with triple glazing, but with a third pane of glass. This extra layer provides more insulation because the units are much thicker.
