Kömmerling is a long-established German maker of PVC profiles, renowned for its multi-chamber systems and the stability of its windows. wendows is an authorised reseller and installer: a premium profile, guaranteed, and fitted by our own teams — no middleman.
Kömmerling offers PVC in several profile depths and chamber counts. Here are the families we fit most often in Belgium — each chosen on site to suit your project and your budget.
The heart of the Kömmerling range: 5- to 6-chamber systems that keep out both cold and noise. The right performance/price balance in renovation as in new build.
The profile is nothing without the right glazing: Kömmerling takes double and triple glazing with a low Ug to aim for thermal excellence without bulking up the frame.
PVC doors matched to your windows, multi-point security hardware and a good level of insulation. A coherent façade, from frame to door.
PVC sliding doors to open onto the garden or terrace, with wide glazed panes and a smooth action, with no heat loss at the threshold.
Beyond the PVC material, it's the multi-chamber design and the stability of the profile that make the difference. The benchmarks specific to the brand, fitted by our teams.
Kömmerling systems multiply the air chambers within the profile: more chambers means better thermal and acoustic insulation, and a stiffer frame that won't sag over time.
A high-performance multi-chamber profile paired with triple glazing lets the complete window reach an excellent level of insulation. High-efficiency double glazing remains the standard in renovation.
Manufacturer warranty on the profiles and the standard hardware, depending on the range. wendows handles the follow-up directly if work is ever needed.
Kömmerling works a lead-free, recyclable PVC, with a circular mindset. A material that stands up to the Belgian climate without warping or yellowing prematurely.
A wide choice of colours through foiling (wood effect, RAL, two-tone inside/outside). White stays the most economical; dark colours call for a suitable profile.
Multi-point locking as standard, steel reinforcements inside the profile and optional anti-intrusion laminated glazing for the ground floor and easy access points.

Buying a good profile isn't enough: a window's performance comes down to the install. As authorised installers, our salaried fitters install Kömmerling windows to the manufacturer's rules, and we handle the warranty and after-sales directly.
Kömmerling isn't our only option. Depending on your project and budget, other window brands may suit you better. Compare them, then we'll decide together on site.

See prices & grants →When you replace your windows, you choose two things: a profile and an installer. Kömmerling answers the first with premium German PVC. In practice, on a renovation job, that means a rigid frame, carefully engineered insulation and windows that won't warp over the years.
The brand is known for its multi-chamber systems: more air chambers in the profile means more thermal and acoustic insulation, and a more stable frame. PVC also remains the most affordable material, which makes it excellent value for money in renovation.
"A good profile, badly fitted, loses its qualities: it's the install that turns a multi-chamber system into a truly high-performance window.
This is where our role as an authorised installer counts. We choose the right Kömmerling profile for each opening, fit to the manufacturer's requirements and remain your single point of contact for the warranty, adjustments and after-sales. No buck-passing between the seller, the manufacturer and the fitter.
Up to six chambers in the profile. The more air chambers a profile has, the better its thermal and acoustic insulation — and the more rigid the frame stays over time. The exact number depends on the range chosen.
On budget, Kömmerling sits in the premium PVC segment: the gap mostly comes down to the profile system, the colours and the glazing chosen. To place your project, start from our window prices & grants page, then ask for a costed quote, window by window.
The price depends mainly on the profile system, the dimensions and the glazing — not just the brand. Here are starting ranges for Kömmerling fitted by our teams, grants deductible afterwards.

It's a long-established German maker of PVC profiles, renowned for its multi-chamber systems and the stability of its windows. The appeal: good insulation, a rigid frame and a wide parts network. As with any brand, the final quality depends as much on the fitting as on the profile — which is why an authorised installer matters.
The PVC profile is hollow and partitioned into several air chambers. The more chambers there are (5 to 6 at Kömmerling), the better the thermal and acoustic insulation, and the stiffer the frame. It's one of the key criteria for comparing two PVC windows.
Yes. Beyond white, the profile can be foiled in many colours: wood effect, RAL, even two-tone inside/outside. Note that white stays the most economical and that dark colours call for a profile suited to the heat.
