Why choose triple glazing in your home? Stepping into a heated house in winter – who doesn’t love that feeling? However, having to turn up the heating sky-high to get and keep your home somewhat warm is less pleasant. With triple glazing, or three-pane glass, you can keep the heat in your home and the energy costs down. Wondering if triple glazing is right for you? On this page you can read all about it.
What are the costs of triple glazing?
Triple glass (or HR++ glass, where the cavities between the glass panes are filled with argon gas instead of dry air) provides better insulation in your home, saving you money on your monthly energy bill. Good for your wallet, in other words. Unfortunately, before you can enjoy these savings, you have to invest in the purchase and installation of triple glass.
Triple glass has the highest insulation value of all types of glass. On the one hand, this makes triple glass a lot more expensive than single glass and double glazing. On the other hand, this also means that you save more energy costs than with any other type of glass. As a result, you will recoup the difference in price and often save more yourself. Below you will find an overview of the average prices of different types of glass, so that you can compare triple glass with the less insulating variants. Based on the prices and cost savings, you can decide whether triple glazing is for you.
| Glass type | Average prices, including installation and VAT |
|---|---|
| Standard double glazing | £115 for a 20m² house, the annual cost saving is then about £140 |
| HR glass | £120 for a 20m² dwelling, the annual cost saving is then about £180 |
| HR+ glass | £125 for a 20m² dwelling, the annual cost saving is then about £220 |
| HR++ glass | £130 for a 20m² dwelling, the annual cost saving is then about £260 |
| HR++ glass (triple glazing) | £170 for a 20m² dwelling, the annual cost saving is then about £280 |

What is triple glass?
The different types of glass can be distinguished according to their insulation value. The insulation value depends on the number of glass panes and the cavity.
- Glass panes: Where single glass consists of only one pane of glass and is virtually non-insulating (it is also said that single-glazed households are “firing for the outdoors”), triple glass has three panes of glass. The middle ground is double-glazing with two panes of glass. You get the idea: single glass is the least popular option these days, and triple glass is the best insulating option.
- S cavity: If you choose HR or HR+ glass, then you choose double-glazing, where the cavity is filled with dry, stagnant air. If you choose triple glass, HR+++, or HR++ glass, then the cavity is filled with a noble glass, such as argon.
The three panes of glass and the filling with argon gas make triple glass the best insulating performance of all glass types.
What are the advantages of triple glass?
Isolation
Argon gas has greater insulating power than stagnant air, making triple glass more insulating than HR and HR+ glass. In addition, three panes of glass provide higher efficiency than two, making it a smarter choice than HR++ glass. Triple glazing insulates as much as twice as well as double glazing.
The result? In summer, your home stays nice and cool because no extra heat enters and no coolness is lost. In winter, triple glazing keeps your home comfortably warm. As a result, you need less energy to keep your house at a pleasant temperature.
In addition, using less energy is also better for the climate. Milieu Centraal therefore advises replacing single glazing with at least HR++ glass as soon as possible.
Other advantages
The insulating effect of triple glazing is not the only advantage. For instance, it is also suitable for households that suffer a lot from noise pollution. Triple glazing blocks much more noise than other types of glazing. Moreover, it prevents condensation.
Are my window frames suitable for triple glazing?
Are you planning to buy triple glazing? Please note. Not all window frames are suitable for triple glazing. This is because it is a lot heavier than other types of glazing: triple glazing weighs ten kilograms more per square metre than double glazing.
When considering switching to triple glazing, it is advisable to have a specialist look at your window frames. The window frames in new-build homes are usually suitable, while older homes are mostly set up for double glazing.
If you want to save money on your energy bill, it is also advisable to look at the quality of your window frames. For instance, it is wise to have rotten window frames replaced immediately when installing triple glazing. After all, good insulation does not only consist of high-efficiency glass, but also of high-quality window frames. If the window frames are of low quality or poorly maintained, they can allow moisture and air from outside to pass through. Both wood window frames and plastic and aluminium window frames are suitable for triple glazing. So choose the window frames that suit you best. Plastic window frames are characterised by their long lifespan, as are aluminium window frames (as they do not rust). Wooden window frames, on the other hand, have a higher insulation value. The choice is yours.
Let triple glazing be fitted by a professional
The insulating effect of triple glazing (and all other types of high performance glass) is only fully utilised if the glazing is fitted correctly. It is therefore very important that triple glazing is installed by an experienced glass fitter. After all, otherwise it will be a waste of your investment.
