Using the substructure insulating profiles, you can adapt all profiles from our module to your desired floor recess height. You get a strong, adjustable, waterproof, and highly insulating substructure for your door thresholds and floor-level elements.


Schwellenunterbau für Anschluss Haustür

Floor-level windows: UDPtherm in combination with our windowsill connection profiles made with Kerdyn™ Green FR


Doors: UDPtherm with adapter profiles for door thresholds made with Phonotherm®200

Custom heights can be achieved by combining standard heights. The individual modules are glued and screwed together with one another. From a structural perspective, this results in a monolithic system without internal joints. This significantly improves the rigidity of the complete system. At the same time, the profiles can be adapted to the existing circumstances at the construction site without sacrificing any stability. Depending on the floor height, securing the profile with steel brackets – preferably on the inside of the building – may be necessary.

Combination of standard heights. Also available in Phonotherm®200.

Standard module available in two different widths.
