The Key Features of Double-Glazed Windows

Double-glazed windows feature two panes. This makes the panel thicker and more insulating than windows made from single glazing, consisting of one pane, because energy loss via conduction is reduced. In addition, double glazing from windows24.com contains argon gas in the spaces between the panes and is externally coated in an invisible low-e layer to further ensure good standard thermal efficiency.

Beyond the glass' basic construction, we also offer ornamental glazing finishes and frosted surfaces to enhance the window’s character and provide privacy. Furthermore, the glass can additionally be treated during manufacturing to provide purpose-designed acoustic properties or increase safety.

Double-Glazed vs Triple-Glazed Windows: Which is Right for You?

  • Although triple-glazed windows provide a higher level of heat insulation and energy efficiency, they are not necessarily “better” than double-glazed windows; the latter can already be more than suitable for certain installation locations, requirements, and budgets, for example.

 

Made-to-Measure Products that Suit Your Needs

  • We can supply windows in a wide range of sizes. 
  • In the configurator you will find our ranges as well as interactive boxes where you can fill in your measurements.

Popular single sash windows are available and for particularly large dimensions, or for increased versatility, we also have double or triple sash options. These sashes can all be fixed, be fitted with a tilt and turn system, turn-only openings, or various combinations of these for different degrees of ventilation and independent operation. The sashes can be divided by mullion bars or rather not have these separators and therefore offer full views out.

As well as standard square and rectangular windows, we also offer a range of unique shapes. Our trapezoid windows can be ideal for gables, for example, while arched models can add much elegance. Depending on the selected shape, upper and lower fanlights can also be added to increase entry of natural light, meaning that rooms feel particularly spacious and welcoming.

Traditional Timber to Anodised Aluminium – Choose Your Frame

A window’s frame influences both its style and functional performance. To suit different needs, we therefore offer five options: uPVC, aluminium, wood, uPVC-alu, and wood-alu. These materials each bring their own unique benefits and a range of different profiles are available for each, which come with varying installation depths, designs, and extra insulation.

Aluminium

Find the Perfect Design and Select Add-Ons

High-Quality Colour Finishes

So that new or replacement windows can blend or strikingly contrast with your property’s façade or existing windows and doors, we offer a range of high-quality colours and decors.

All coatings are professionally applied during manufacturing via precise technical processes to ensure lasting vibrance.

For uPVC windows, classic white or anthracite are popular options, as are innovative aluplast decors, Woodec and Aludec. These decors make the frame look like it is made from timber or metal, both in terms of appearance and texture while the benefits of the modern material core are retained beneath.

On the other hand, for wooden windows, for example, a water-based varnish can be added to redden or darken the natural tone of the timber. Alternatively, a particularly extensive range of RAL colours can be selected from. Matching glazing bars can also be added, whose number and placement on the glass can be specifically determined.

Protective Roller Shutters

Roller shutters are modern products, popular in Germany and other parts of central Europe. They feature a box that is installed above windows and doors, or rather fixed inside the reveal. The box contains a curtain blind that descends along guide rails to shade interiors from the sun or darken rooms by the desired degree for sleeping. The curtain can be made from premium uPVC or robust aluminium and also adds an extra layer of heat insulation and break-in protection to property exteriors.

Custom Insect Protection

To protect interiors from mosquitoes and other bugs, our double-glazed windows and French doors can be fitted with an insect screen. 

Available as a frame that can be easily clipped in and out, or rather ordered integrated inside a roller shutter box, the nets can be made from quality fibreglass or steel. They also come in different colours, maintain clear views out, and don’t disrupt entry of light through the glazing.
