With superior energy and acoustic performance, triple glazed windows are moving from common to standard throughout Europe. They are constructed from three panes of glass and deliver improved thermal insulation, noise reduction and energy savings to homeowners. Our top of the line triple glazed windows deliver more comfort in the home and higher energy savings than double or single pane options. Best of all, because it is so common in Germany, the price difference is usually less than 10% for standard glass. Experience the difference yourself.

What is Triple Glazing?

Simply put, triple glazing is three panes of glass built into a window. This modern innovation outperforms single and double glazed windows across the board. Windows are the most exposed part of a home and consequently provide abundant opportunity for energy loss.

We are all familiar with the importance of wearing multiple layers of clothing in winter. Each additional layer provides not just another barrier against the weather, but also creates a space to trap warm air between them. Windows are similar.

Triple glazing adds more than a third pane of glass, but also a second air cavity (see illustration left). Similar to wearing multiple layers of clothing in winter, both the pane and second air gap create further barriers against the elements and heat loss. Each air gap is also typically filled with argon which is heavier and less conductive than air. This makes it even tougher for energy to move through, reducing loss.

Triple vs. Double Glazing

Compared to double glazed windows, triple glazing can offer up to 40% more energy efficiency. Particularly in cold climates where heating costs are higher, this can add up to significant savings over the life of the window.

Adding a third pane and creating a second air cavity sees a substantial boost in energy efficiency, sound reduction and security. Finally, separating the glass with warm edge spacers and filling the gaps with argon gas provides the ultimate combination of savings.

All of our frames are built for triple glazing, whether they be timber, uPVC or their aluminium clad versions. Insulate yourself against rising energy costs and stricter building standards with triple glazed windows.

Does Triple Glazing Cost More?

There is a widespread myth that triple glazing is expensive and may not be worth the extra cost when spread over the life of the window.

While this may hold some water in countries with lower energy standards and building regulations, it could not be further from the truth for German windows. Triple glazing is so common in Germany that the price difference for new windows is typically 10% at the most for standard glazing.

While the insulating value is improved by 40% the price differs not more than 10% from double-glazed to triple-glazed windows.

Are Triple Glazed Windows too Heavy?

Another common concern is that the additional layer of glass is unduly heavy and may cause issues for the frame or sash, as well as making them somewhat more difficult to open or close. This is another myth, based on fitters in other countries trying to jam three panes into an existing double glazed unit.

Ironically, it may be cheaper to buy triple glazed windows abroad where they are standard than at home where they aren't.

All of our windows feature the best hardware and precision built frames, designed for triple glazing from the start. Moreover, every single piece of the window is made in Germany, ensuring the same reliability and quality people around the world expect from us. In fact, opening your German made windows and doors will probably be easier and smoother than your current single or double pane ones!

Security and Burglary Protection

A third sheet of glass in your window makes them that much more difficult to break through. Neuffer also offers laminated safety glass in several configurations which can be added on the exterior, interior or both depending on your requirements. Exterior only is best if security is your only concern while interior only is best when safety is key, such as an area where kids typically play and the danger of broken shards would be unacceptable.

Noise Reduction

The acoustic performance of triple glazing is also much better than glazed windows with only two panes. The additional glass and air gap reduce the ability of heat to move through, from one side to the other. Whether this is cold moving from outside into the house, or sound waves moving from a passing car inwards, the effect is the same. The triple barrier and argon gas filled cavities reduce their energy and ability to move, meaning less cold and sound entering the home.
