Kömmerling 76 AD
PVC window Kömmerling 76 AD
Double butt seal
The 76 AD system pairs a 76 mm, five-chamber profile with a double butt seal: high thermal insulation for outstanding value, in renovation as well as new build.
It takes glazing up to 50 mm (double or triple) and optional anti-burglary reinforcement. Available in white, wood-effect or proCoverTec shades — lead-free PVC, calcium-zinc stabilised.

Finish
proCoverTec, the surface coating
Kömmerling profiles can be given proCoverTec, a surface coating that marries looks with robustness. It hugs the profile perfectly, withstands everyday use and has a slightly textured finish that is pleasant to the touch.
Its satin surface holds less dirt, cleans easily and has antibacterial properties. On colour, a wide choice of plain and metallic shades is available, inside and out — you can even choose a different colour on each side: for example a contemporary black on the façade and a bright white inside.

Colours & finishes
White, plain colour or wood-effect
Thanks to the proCoverTec coating, your profile dresses to your taste. Three broad families of finishes, all resistant and easy to maintain.
Elegant white
White remains the great classic. On Kömmerling 76 profiles, it benefits from a high-quality PVC that is highly weather-resistant: the smooth, glossy surface keeps its shine over time and cleans in a single wipe.
Plain colours
After some character? Plain-colour foiling opens up a wide choice of shades — from a bright red to an elegant dark grey, by way of a deep blue. Like white, these finishes resist the weather and are very easy to maintain.
Wood-effect
Wood-effect foiling plays both cards: the warmth and character of wood, without its constraints. The profile stays durable PVC — no sanding or repainting to redo, unlike timber joinery.
Design
Thought through down to the smallest detail
The Kömmerling 76 brings together the latest PVC frame technologies. Its modular design tailors the window to each project, with slim profiles that let the light in while housing insulating triple glazing — for fast installation and easy replacement of your old windows.
High thermal insulation
Even in the standard version, the Kömmerling 76 shows an excellent insulation figure (Uf from 1.1 to 1.0 W/m²K depending on the profile) — an already high-performing baseline against heat loss.
Stability over time
Clever contact points hold the steel reinforcement firmly in place without creating a thermal bridge. The frame keeps its geometry year after year.
Optimised chambers
The profile chambers are precisely calculated: strong thermal and acoustic insulation, high stability and high load capacity, even with heavy glazing.
Enhanced security
The hardware is fixed through several profile walls, with reinforced thickness in the load zones — for a strong, secure window.
Wide choice of glazing
Glazing up to 70 mm: triple glazing, enhanced thermal insulation, acoustic or safety glazing, to combine as you need.
Fast, invisible installation
Fixing with steel brackets specific to PVC: a fast, clean and fully concealed installation, for a neat and secure result.

AluClip option
Kömmerling 76 AD AluClip
The Kömmerling 76 AD AluClip is your PVC frame clad in aluminium: the look of aluminium and an almost unlimited choice of colours (PVC AluClip), without giving up the advantages of PVC.
Love the qualities of PVC but dream of an aluminium look or an almost unlimited choice of shades? The AluClip dresses the outer face of the profile with a clipped-on aluminium shell: inside, all the comfort of PVC (insulation, easy upkeep); outside, the looks and robustness of aluminium.
Where proCoverTec finishes are limited to a range of shades, the AluClip opens up almost every colour. The aluminium is indeed powder-coated: a powder paint is applied then oven-cured to form a hard, durable, weather-resistant coating — in virtually any RAL shade.

Frequent questions
Answers specific to the Kömmerling 76 AD.
Does the 76 AD offer good insulation?
Yes: with a Uf of 1.1 W/m²K and high-performance double glazing, it covers the vast majority of renovations. For a very exposed façade or the highest requirement, step up to the 76 MD.
What does the double butt seal change?
Two seal lines, inner and outer, ensure the seal between the frame and the sash. It is an excellent performance/price compromise; the 76 MD adds a third, central seal.
Can you get a wood look in PVC?
Yes. The proCoverTec finish offers a wood-effect foil and 26 plain or metallic shades, inside and out.
Is the PVC of the 76 AD environmentally friendly?
It is calcium-zinc stabilised, lead-free, and remains recyclable at end of life.
76 AD or 76 AD AluClip: what is the difference?
It is the same PVC frame, with the same performance. The AluClip simply adds an aluminium shell clipped onto the outer face: the look becomes more "aluminium" and the choice of colours almost unlimited (nearly every RAL shade). Inside, everything stays the same.
Does the AluClip change the insulation or the upkeep?
No. The core of the profile stays PVC: the same insulation values (Uf 1.1, Uw 1.2 W/m²K) and the same simple upkeep. The aluminium shell is powder-coated, and just as easy to clean.
When should you go for the AluClip?
If you are after a specific RAL shade not available in proCoverTec, an aluminium exterior look or extra protection for the exposed face. Otherwise, the standard 76 AD already covers many needs with its proCoverTec finishes.
