Further Information

Kömmerling uPVC windows – a wide range of options

Since its profiles first entered the market in 1967, innovative customer-oriented window and door systems have been an unwavering hallmark of the traditional German brand. Having made an international name for itself, the company now sets standards in modern window and door construction, impressing with expertly designed, high-performance product ranges characterised by quality seals, secure locking systems and energy-efficient frames. Purchasing Kömmerling windows and doors from windows24.com means excellent customer service from our expert team, a competitive purchase price, and wide scope to personalise products.

With all options clearly laid out and selectable in our sophisticated online configurator, we work with our suppliers to have designs and specific functional requirements become reality. Durable woodgrain foils or a range of RAL colours, such as anthracite grey, can be selected for Kömmerling windows, for example. Or perhaps privacy and thermal efficiency are your priorities; in this case decorative glass or triple glazing can be added to configurations.

The choice of profile

At windows24.com, the available Kömmerling profile systems differ in terms of design, frame depth, thermal performance and the number of in-built chambers or seals.

This is ideal for meeting different customer needs. With construction depths ranging from 70 to 88 mm, for example, the windows can fit a wide variety of wall depths, including those of low-energy new builds featuring multi-layered insulation.

In terms of the number of seals and thermal performance, our Kömmerling profiles have product names ending in the abbreviations "AD" or "MD". Literally translated from the original German, this describes the number of built-in seals the profiles have; AD have two, whereas MD have three. The greater the number of seals and chambers a profile has, the more insulating it will be.


Superior thermal insulation can be recognised by a low u-value, defining a reduced transfer of heat. Kömmerling 76 MD has a lower thermal uw-value of 0.77 W/m²K, for example, than its counterpart Kömmerling 76 AD model with 0.81 W/m²K.

Although MD profiles perform slightly better in terms of insulation, our full range of Kömmerling windows offers an above standard performance. uPVC as the base material, combined with German design innovation, meets the highest thermal standards for modern living, superior to that of wood or aluminium frames. This reduces energy loss and costs by contributing to the maintenance of a stable interior temperature.

Security meets elegance

Insulation is not the only key functional advantage of Kömmering profiles; thanks to a built-in steel reinforcement, hardware fittings and quality locking points they are also highly secure, sturdy products.

Both door and window systems feature the market-leading European tilt and turn mechanism which allows for different degrees of air supply as well as excellent security, even when left tilted ajar overnight.

Alongside the window profiles displayed on this page, Kömmerling also offers homeowners a range of door systems, available in different styles. A wide range of French doors in different colours can be purchased from windows24.com, for example. Brightening interiors with their generous glass window surfaces, they are perfect at making the space appear larger and more welcoming. Lift and slide patio door systems, such as the Kömmerling PremiDoor 76, are then also available, ideal for those after larger fronts or barrier-free thresholds.

Frequently asked questions

As our products can be highly personalised, the exact cost of a window from the Kömmerling range varies depending on the glazing, profile frame or security add-ons selected. In general though our uPVC windows offer a great price to performance ratio and in its most basic configuration a Kömmerling window can be purchased from 39 €. Any further selections then made to the model, which impact the price, can be seen displayed live in the configurator.

In terms of installation costs, at windows24.com customers can reduce costs and self-install products with our step-by-step illustrated instructions on how to install or organise for local installers.

Passive houses are low energy buildings, required to achieve excellent thermal insulation. Our Kömmerling range, such as the 88 MD, 76 MD and 76 AD window systems, with low u-values of 0.72, 0.77 and 0.81 W/(m²K) respectively, meet the requirements and are therefore suitable to be installed in passive houses.

All materials used for the frames in windows and doors bring their own unique benefits and the choice comes down to personal requirements and taste. Whether used in windows or doors, wood creates a warm traditional atmosphere, for example, and adds a unique textured pattern. uPVC windows, on the other hand, impress with their superior thermal insulation and modern properties like low maintenance. Regardless of whether the product is from our range of French doors, windows, or lift and slide door systems, uPVC can also be flexibly designed to feature a durable woodgrain replica decor.

At windows24.com, new uPVC windows from Kömmerling are available in a wide range of colours and decors. Easily selectable in our online configurator, all are long-lasting, UV and weather-resistant and are applied onto window and door systems during manufacturing in a special process. Most popular with customers are our colour and decor variants, golden oak, nut brown, and woodgrain grey.
