Trocal WarmCore combines a highly thermally insulating PVC core with a durable aluminum surface. This combination creates a hybrid system for modern windows and doors, combining energy efficiency, quality materials and clean lines.
The inner core reduces heat loss, while the aluminum layer protects against weather conditions and ensures a uniform and precise appearance. Trocal WarmCore is suitable for both new construction and renovation, offering a harmonized aesthetic throughout the building.
Trocal WarmCore 76 further expands on the hybrid principle. The greater construction depth, multi-chamber design and continuous aluminium surface enable generous formats. The system is particularly suitable for sophisticated architecture and sustainable building concepts.




Trocal WarmCore 76 In is an inward-opening, tilt-and-turn window system that combines modern design with high stability and good energy efficiency. The hybrid construction combines a multi-chamber PVC core on the inside with a surrounding aluminum surface on the outside. The PVC core supports the window’s thermal insulation, while the aluminum surface provides a high-quality appearance and offers additional protection against weather conditions. The result is a window system that meets the functional and design requirements of modern buildings.
The design guarantees reliable protection against wind and rain, while enabling convenient everyday use. The system can also be used to create larger window formats, enabling brighter environments and larger glass surfaces.




Trocal WarmCore 76 Pure is an inward-opening, tilt-and-turn window system with a modern all-glass look. The flat exterior makes the window sash invisible from the outside. This creates a smooth and uniform facade appearance with clean lines. At the same time, the design allows for a higher percentage of glass, allowing more natural light to enter the interior and creating bright, open spaces.
On the inside, a multi-chamber PVC core provides good thermal insulation properties and supports the stability of the profile construction. The surrounding aluminum surface gives the system a precise and high-quality appearance, as well as protects the construction from the effects of atmospheric conditions. This combination creates a window system that combines modern design with functional properties.




Trocal WarmCore 76 Door is a hybrid entrance door system that combines stability, thermal insulation and quality design. A multi-chamber PVC core on the inside supports the thermal insulation and ensures the stability of the construction. The surrounding aluminum surface gives the entrance door a precise look and offers additional protection against weather conditions. This creates a durable and easy-to-maintain entrance solution for various types of buildings.
The design ensures high dimensional stability and reliable operation even with frequent use. At the same time, the system offers good protection against wind and rain and enables comfortable everyday use.
Trocal WarmCore offers a uniform aluminum look with many color and texture options. This includes RAL colors, metallic and fine-textured variants, as well as wood imitations. Different colors can be selected for the interior and exterior. The surface is weather-resistant and easy to maintain.
The thermal insulation properties of the hybrid core help reduce heat loss and improve the energy efficiency of the building.
Trocal WarmCore offers a complete system for windows, doors and large opening solutions. The combination of insulating performance, material quality and modern appearance creates a reliable basis for contemporary building projects.
We create inspiring spaces that combine modern design with sustainable functionality, turning your vision into reality.
