The company IsoProfil

The research, development and manufacturing departments of IsoProfil work closely together to deliver solutions for our partners’ requirements in reproducible and efficient series production. Use of the latest and most appropriate technologies ensures that every product that leaves our plant fulfils the quantity and quality requirements.
Carefully considered and ongoing investment in manufacturing facilities combined with the systematic further training of our employees provide quality assurance and constant supply capability in line with your specifications.
IsoProfil develops and supplies precision profiles and system components – on a pre-series basis – using robust production processes for mass production..


By separate customer request, we present realistic solutions shortly after the feasibility study.

IsoProfil uses specially developed production facilities for the series manufacture of medium and large batch sizes. Reliable just-in-time delivery allows us to minimise inventory costs and directly pass these savings on to our customers.

Location Germany

Right in the middle of the action: In Germany, our location is in North Rhine-Westphalia, one of the strongest industrial regions in Europe. Wuppertal has been our home for almost 40 years and our customers still benefit from the strategically ideal location in the Bergisches Land region between the Ruhr area and the Rhineland.

Location Switzerland

Since 2022, our Swiss customers also have a direct route to IsoProfil. With our headquarters in Baar and a warehouse in Muri, we can now respond to customer requests even faster and more straightforwardly.


IsoProfil GmbH & Co. KG was established in 1983 by Dipl.-Ing. Dieter Sander, a qualified engineer and the managing sole shareholder. The company’s headquarters in Wuppertal are located in the heart of North Rhine-Westphalia in the industrialised Bergisches Land region between the Ruhr and the Rhineland. The company is family-owned and is a member of the Berlin-based German Association of Family Entrepreneurs.

In the first two decades of its existence, the company mainly focused on the development and manufacture of spacers – metal profiles for windows which are located in the interior space of an insulating glass pane. These profiles quickly gained in popularity under the “IsoProfil” brand, not least due to their good working properties and cost efficiency. Today, this patented product is still widely known in the relevant business segments and customer groups as “The IsoProfil”. The spacers along with mainly extruded special profiles made of aluminium, brass, steel and copper are currently manufactured on special internally designed roll forming machines equipped with CO2 lasers and solid-state lasers.

New product groups were added in the following years. In addition to the previously mentioned spacers, IsoProfil’s services in the areas of engineering, project planning and manufacture turned to job lots and prototypes prior to series production.

IsoProfil’s services include advice, inspection, planning and implementation – also with a performance guarantee after delivery based on the scope of responsibility.

Today, the company regards itself as more than a manufacturer of profiles and profile systems, having diversified into an application consultant for a wide range of component and profile solutions. This service is highly valued by many of our partners who require the building of prototypes. With decades of experience, our employees possess the specialist and strategic know-how to solve our customers’ challenges no matter the project.


Quality assurance is an important priority for us and we are always guided by the individual wishes of our customers. Possible errors and vulnerabilities are identified at the outset in accordance with the customary quality management guidelines, for example the FMEA (Failure Modes and Effects Analysis) system, and excluded at the planning and development stage. We regard these regular quality and assurance checks as indispensable in order to guarantee that you receive optimised test values and cost-effective manufacturing of your product.
An economical approach to processing raw materials in our modern production facilities pays off for our customers. The research, development and manufacturing departments of IsoProfil find safe and efficient solutions for our customers’ requirements.

Every workpiece or component that leaves our company undergoes comprehensive and documented product and quality assurance. On request, all parts are manually checked and optimised in great detail, a service which is of particular benefit for the manufacture of luxury goods. We have been certified to DIN EN ISO 9001 since 1998 and thereby fulfil international quality criteria. The feedback we receive from our regular surveys of customers and suppliers confirms their satisfaction with our quality.

Guiding principle

Innovation based on tradition

Over 30 years of experience combined with the in-depth expertise of our highly trained team, the manufacture of products of the highest quality as well as the tapping and development of new markets form the bedrock of our success and that of our customers.

IsoProfil’s number one objective is to develop and manufacture products with the internationally valued and/or sought-after quality hallmarks “Made in Germany” and “Made by IsoProfil”. From prototypes to series manufacture through to after-sales support and long-term availability of spare parts, our company has always attached great importance to certification, continuous development and further training. As an extra accompanying measure, IsoProfil reviews its manufacturing system in cooperation with external recognised organisations. Because of this, the quality of the services based on our products is maintained at a high level with further improvements additionally planned.

Close cooperation with our customers is essential for finding creative solutions to their specific product requests and so that we can implement these solutions in a cost-effective manner.

Increasingly demanding requirements and the accompanying rapid advancement of technology call for a broad and flexible portfolio of services. Our employees have the in-depth expertise to deliver these services day-in, day-out, and thanks to them our specialist services are in high demand.

Particularly short decision-making channels and entrusting individual employees with a high level of responsibility results in highly motivated teams who find successful and reliable solutions to each challenge for the benefit and satisfaction of customers.

We assign varied tasks to our employees as well as the opportunity to work on projects autonomously. This allows them to prove and develop their proactive approach to work, their sense of responsibility, and their independence. We strongly encourage cooperation between colleagues. If you are interested in joining our company, please check out our current job advertisements.

We continually reinvest a portion of our profits to maintain and further optimise the high quality of the above-mentioned market segments and services. The objective of our succession planning is to continue and build on our company’s successful history in Germany. A strong ability to adapt to changing circumstances and a solid economic footing will help us achieve this objective.


For us, competence in metal and plastic also means that we have to act responsibly in relation to our environment. We have a fundamental duty to examine the processing and recycling of raw materials at our production facilities from an economic viewpoint. As well as saving resources and costs, this also increases the competitiveness of our customers.

While we use raw materials like steel, stainless steel, brass, copper and plastic, we rely most of all on aluminium. This metal is particularly resistant to corrosion, low in density, easy to process and highly suitable for recycling.

The research, development and manufacturing departments of IsoProfil also find safe and efficient solutions for our partners’ requirements.



IsoProfil is one of many successful companies which regularly donate a share of their profits to social projects. We have been supporting various national and international institutions since our foundation, with most of our donations going to projects supporting children, mothers and education.
