GEALAN-acrylcolor® ⭐ Komsta

GEALAN-acrylcolor®

Gealan introduced GEALAN-acrylcolor® technology to the market in 1980. The color is provided by a layer of PMMA, or acrylic glass, which is fused with a standard white PVC profile during the co-extrusion process. Foils and GEALAN-acrylcolor® are two different ways of adding color to a PVC profile. Decorative foil is attached to the profile using an adhesive layer. In GEALAN-acrylcolor® technology, the colored acrylic layer is created together with the profile: the PVC and PMMA are fused in the extruder nozzle, without the use of glue.
‍
Komsta offers both finishes. Foils provide options such as wood-effect decors, while GEALAN-acrylcolor® offers a uniform RAL color or a metallic shade. Both can also be combined in a single window. PMMA is one of the hardest materials that can be extruded and is significantly harder than PVC. This is why the GEALAN-acrylcolor® surface is ideal for the exterior side of a window, where it is exposed to sun, wind, rain, cold, and temperature fluctuations.

Advantages of GEALAN-acrylcolor®

The acrylic layer protects the window color from the sun, weather, and damage, from installation through decades of use.

‍

No peeling: the durable bond between PVC and PMMA eliminates the risk of the color layer peeling or flaking.
Scratch-resistant: the hard acrylic layer is more scratch-resistant than most building materials.
Weather-resistant: the surface retains its properties for decades, even in extreme climates.
Colorfast: the color remains stable for decades, even in strong sunlight.
Polishable scratches: the acrylic layer is thicker than any lacquer coating, so minor scratches can be polished out.
Easy to clean: the uniform, brushed surface is resistant to dust, dirt, and pollen.

Metallic shades

In addition to solid colors, Komsta offers windows and doors with a GEALAN-acrylcolor® surface in metallic shades as well, including gold. The acrylic layer contains metallic pigments that give the PVC window the look of aluminum.

According to their own materials, Gealan is the only window system supplier to offer PMMA surfaces in metallic shades. The palette includes six shades: bronze, gold, pearl beige (RAL 1035), white aluminum (RAL 9006), silver (similar to RAL 9007), and DB 703.

The metallic pigments are evenly distributed throughout the acrylic layer, giving the profile a deep color and an elegant sheen. A Komsta advisor will confirm the availability of a chosen shade for a specific model during the quoting process, or you can check it yourself in the WH-Okna quoting software.

The co-extrusion process

The GEALAN-acrylcolor® profile is created through a co-extrusion process, in which two liquid materials are combined in a single tool:

The main extruder feeds liquid PVC.
A second extruder, known as a co-extruder, feeds liquid PMMA in the chosen color.
Both materials are permanently bonded in the machine's nozzle.
The surface is polished to achieve a uniform, brushed texture.

Gealan also uses tri-extrusion, which involves extruding three raw materials at once: a recycled plastic core, PVC, and colored PMMA on the visible outer surfaces. Windows made from GEALAN-acrylcolor® profiles are fully recyclable.
‍

Komsta manufactures windows and doors from ready-made profiles using a modern machine park, drawing on over 30 years of experience in window and door production. Gealan systems also allow us to create windows in custom shapes and large sizes.

Color palette

Gealan offers the GEALAN-acrylcolor® surface in 18 colors from the standard and extended palette, as well as in 44 special colors. The available palette depends on the window system, so please confirm your chosen color with a Komsta advisor during the quote process or check it in the WH-Okna estimation software.
