Optimised safety and comfort

Concept System® 77 includes a high-quality flush door system, which meets the elevated requirements regarding thermal insulation, stability and security.
With regard to security, different door variants are specially designed and tested for burglar resistance, fire resistance, bullet proof and solutions for panic situations, meeting the most severe European standards.

This standard flush door range is available in all inward and outward opening types, realised with a wide range of door locks to meet every kind of locking demand.

To ensure the tightness of the door, specially designed insulation strips are used to avoid possible bending of the element, caused by temperature difference between the in- and outside of the building.
