Kömmerling K-vision uPVC windows, supply only
uPVC windows in a Klass of their own: K-vision by Kömmerling is a uPVC window system with a recessed, a square-edged and a flush profile look, and a lift-and-slide door in the same system. We supply it made to measure, supply only — no installation — with a quote for your sizes.
uPVC
4 profiles
Flush uPVC profile, 76 mm deep — the choice when there is little depth to spare and aluminium is not an option. If you want a recessed face instead, look at the K-vision Trend.
Square edges and a block-shaped frame, for an elevation where everything has to be crisp. Apart from the profile look, this is the same K-vision as the Trend.
uPVC lift-and-slide door from K-vision. The usual reason to choose it is that your windows are K-vision too.
The sash sits back within the frame, so from outside an opening window is hard to tell from a fixed one. If you want visible square edges instead, choose the Cube.

Kommerling windows: what is K-vision?
K-vision is a uPVC profile system for windows and doors from the range of profine, the profile group behind Kömmerling. That is why you also come across it as "Kommerling K-vision". A fabricator cuts, welds and glazes the profiles into a finished window; we supply that window made to measure and without installation.
Trend, Cube, Classic and the PremiDoor
The K-vision profiles for windows and doors differ mainly in how the window looks from outside. The Trend has a recessed face: the sash sits back in the frame, so an opening window is hard to tell from a fixed one. The Cube is just as deep, 120 mm, but square-edged, with a straight corner weld instead of a mitre; with a woodgrain foil it becomes a uPVC replacement for a timber window. The Classic is flush and, at 76 mm, a good deal shallower, for replacements where the reveal leaves little room. Then there is the PremiDoor, K-vision's lift-and-slide door, so a sliding door next to your windows stays in the same system. Which profiles can be configured today is shown on the cards above.
Colour: proCoverTec or foil
K-vision colour goes onto the profile in one of two ways: as a foil, or as proCoverTec, Kömmerling's own colour finish, which the manufacturer describes as colourfast. On white uPVC there is no layer that can come loose: that is the colour of the material itself. How a coloured profile holds up over the years is not something we have measured ourselves.
Kommerling windows: reviews and quality
We do not publish customer reviews we cannot check. What is established is the system data: K-vision is tested for burglar resistance class 2, for air tightness between 450 and 600 Pa and for fire resistance EW30 and EI30, with EW60 as an option. The Cube comes with hardware approved under SKG, the Dutch security mark. The profiles are lead-free and fully recyclable. The profile system holds a KOMO certificate, the Dutch quality mark for building products: profine Nederland and Kömmerling are listed with a valid certificate in the public KOMO register. That is a property of the profiles, not a mark of ours or of the factory that makes your window. A class always applies to the complete unit, including the hardware and the way it is installed: whoever fits it helps decide whether the result reaches that class.
For the Trend and the Classic, the detail drawings are on the site: fixed glazing, tilt and turn window and the inward and outward opening door, as a drawing on the page and as a PDF. We do not issue DWG files.

K-vision by Kommerling: frequently asked questions
Is K-vision made by Kömmerling?
Yes, in the sense most people mean it: K-vision comes from the profile range of profine, the group that Kömmerling (Kommerling) belongs to. The window itself is made by a fabricator who processes the profiles.
Does K-vision have a KOMO certificate?
The profile system does: profine Nederland and Kömmerling Chemische Fabrik (certificate K21725/05) are listed with a valid KOMO certificate in the public register. KOMO is the Dutch quality mark for building products; the certificate is a property of the profiles. It is not a Rovenzia mark and not a certificate of the factory that makes your window.
Which K-vision profiles does Rovenzia supply?
The Trend, the Cube and the Classic for windows and doors, and the PremiDoor as a lift-and-slide door — all uPVC. Each has its own page with a cross-section, specifications and the layouts you can put together with it. The cards at the top of this page show which can be configured today.
What is the difference between Trend, Cube and Classic?
The Trend and the Cube are both 120 mm deep with Uf 1.2; the Trend has a recessed sash, the Cube is square-edged with a straight corner weld. The Classic is flush, 76 mm deep and insulates slightly better at Uf 1.1.
Is there a K-vision Trend 76?
No. The Trend is 120 mm deep; 76 mm is a different Kömmerling profile. If you are looking for a flatter 76 mm K-vision profile, look at the Classic.
How much do Kommerling K-vision windows cost?
That depends on the size, the layout, the glass and the colour, which is why we do not give a fixed price. You put your window together in the configurator and receive a quote for your sizes within three working days, in GBP and excluding UK VAT and import duties. Delivery to the UK is quoted with your offer; we do not install.
Can I order a K-vision front door?
You can put together a door in K-vision profile, opening inwards or outwards — both are also in the detail drawings of the Trend and the Classic. The configurator shows which door panels go with it.
Can I buy Kommerling windows supply only?
Yes, that is exactly what we do: K-vision windows made to measure, without a showroom and without installation. We don't claim an official dealer title. You order online on the basis of a quote, and you arrange the fitting yourself or with an installer.
Does K-vision have a sliding door?
Yes, the PremiDoor: a uPVC lift-and-slide door in the same system as the windows. If your windows are K-vision, a PremiDoor keeps the same line.
Is K-vision uPVC or aluminium?
uPVC. If you are looking for aluminium, look at Aluprof or Reynaers in our range.
Which Kommerling windows can I order from you?
Those in the K-vision system. The profile system comes from profine, the group behind Kömmerling; from it we supply the Trend, Cube and Classic as windows and the PremiDoor as a lift-and-slide door, made to measure and supply only. We don't carry any Kömmerling system other than K-vision.
