aluplast GmbH

aluplast GmbH is a German-founded, family-owned manufacturer of high-performance uPVC (plastic) profile systems for windows, doors, and sliding solutions. The company serves window fabricators, construction companies, architects, and planners across Germany, Europe, and North America. Its product lineup includes window profile series, entrance door systems, and sliding door solutions — all engineered for energy efficiency, security, and design flexibility.

With sales sites worldwide, aluplast ranks among the most dynamic international window profile system manufacturers in Europe. In the U.S. market specifically, aluplast strengthened its position through the acquisition of Chelsea Building Products, a Pittsburgh-based uPVC system provider, expanding its portfolio to include not only window and door systems but also cladding, cover profiles, and roller shutters.

What sets aluplast apart is its commitment to compatible, open systems — products that can be combined with each other, allowing for constant expansion and the freedom to choose solutions suited to market needs. The company holds certifications including TÜV Süd ISO 9001, RAL quality marks, and Passive House Institute recognition, underscoring its reputation for technical rigor and reliability.

energeto® neo IDEAL NEO ADMD

INNOVATION IS IN OUR NATURE

Today's fast-paced world presents us with many challenges. In contrast, simple forms and clear structures are the answer. They are concrete and calming.
The energeto neo system was inspired by the Bauhaus style. This style revolutionized architecture. Simple and elegant design for everyone. Lots of light and the combination of indoor and outdoor elements are themes that are as relevant as ever, even today, hundreds of years later.

energeto® neo is an extremely attractive offer for customers who appreciate modern style. The system's straight, symmetrical cubic shapes are a distinctive feature.

Smart-slide NEO - a new dimension of comfort

The Smart-slide NEO sliding door is a new development in the door segment. It is a sliding door that is an attractive alternative to PSK/PATIO terrace doors. Its secret lies in its simplicity and the use of proven solutions.
It is a smart choice for both family homes and public buildings where terrace doors are to be installed and where the following are expected above all
ease of use and reliability.

The minimalist design of Smart-slide NEO is reminiscent of Scandinavian design. The simple, symmetrical shapes and narrow, expressive contours give the windows an extraordinary lightness and elegance.

The guiding principles of our contact center are professionalism and an individual approach to the questions of the company's customers and clients. We understand that only quality service that meets customers' expectations will secure loyalty to the company at every stage of long-term cooperation.
That is why we:
- make our services simple, accessible and convenient for customers,
- identify customers' needs so we can help with professional advice.
We value our customers' time.

The decorative films contain special color pigments that reflect up to 80% of infrared radiation, preventing the surface from heating up, while increasing the functional reliability and service life of the structure.

The new woodec surface offers a faithfully
the look of natural wood thanks to its deep embossing and matte top layer.

The new aludec surfaces reflect this trend in full as they are available in seven attractive shades,
ranging from white and gray, through bronze, anthracite and metallic Alux to a deep black effect
