More than five decades ago Metecno-group established a new way of building with the automated and continuous production of insulated wall and roof panels with external steel sheets. The big success of these panels led to a quickly increasing demand and a fast expansion within but also outside of Europe. In 1998, the German subsidiary, originally part of a joint-venture with DLW AG in Bietigheim-Bi... see moressingen was fully integrated into the Metecno-group.
In 1994, a modern production facility was established in Thuringia. Thanks to the ongoing investment in new technologies, this facility represents the most up-to-date technology within the field of sandwich panel production. In 2016, a second product line was put into operation at this plant, resulting in a striking increase of production capacities and also in a massive reduction of lead and delivery times. Due to the increasing requirements for thermal insulation and fire resistance as well as for cost-effective construction, the sandwich elements have become a vital part of the building sector. Various types of profile geometry and a vast choice of available colours make architecturally sophisticated solutions possible.
An extensive range of accessories such as edge profiles, pilaster strips as well as filler blocks and sealing tapes complement our product range, making deliveries of complete packages possible. Our panels are commonly used for industrial, commercial and agricultural building as well as for the building of sports facilities. Special products with highly specific structural-physical requirements are mostly applied for acoustic construction or technical insulation. Our most important export markets are the Benelux countries, Austria, Switzerland and Scandinavia. Besides our constantly high quality of products, especially our excellent customer service makes Metecno stand out on the German market. A highly motivated team led by experienced specialists ensure an ideal customer support on every level. This results in a high rate of regular customers representing our focus on continuity and partnership at eye level.

Manufactured in | Germany |
This sandwich panel with highly heat-insulating CFC-and HCFC-free polyurethane rigid foam core is suited best for today's requirements for thermal insulation and moisture protection.
Besides that, it may also be used as a visual design element for façades.
The sloped element joint with integrated sealing closes during installation without any additional working steps. Thus, one single operation produces a reliable connection without any thermal bridge. The G4® panel ensures a very high installation speed and is therefore THE preferred product-of- choice for many professional installation companies.
The optional stucco-embossing on the internal steel sheet reduces the mirror effect on the surface.
Depending on the application, a minimum roof slope of > 5° is recommended.
