Center Seal System

A modern centre seal window system with sloped rebate.

Centre seal system

An attractive system of the new generation
The characteristic feature is the centre seal arranged in the sash profile. The gasket in the indoor sash leg forms the second sealing level. In addition a dust gasket can be integrated in the frame leg. The weldable gaskets coextruded with the profile facilitate clean corners for optimised sealing properties.
The key design attributes are slim face sections, modern straight lines in the EuroFutur MD Classic design, the highly distinctive contours of EuroFutur MD Exklusiv, the self-contained design combining both variants in semi-offset EuroFutur MD Classic, and the soft mouldings of all visible profile edges. The potential of aluminium covers rounds off the system with a virtually unlimited range of colour schemes. The potential of colour accents is provided by RAL powder coatings and anodised surfaces projecting the metallic character of the aluminium covers.
The standard frame-sash structure is designed as a five-chamber system.
This perfected technology and the installation depths 70 and 80 mm ensure above-average thermal insulation properties with Uf values of 1.1 and 1.2 W/m² respectively.
Backset steel reinforcements can be used to form a sixth chamber.

Particularly stable hardware parts installed at the centre of the profile ensure security and protection against forced entry. The findings of the performance test comply with loading group C – the highest categorisation.
This system also sets an example from the ecological viewpoint – The KÖMMERLING brand is the first key producer in the world to manufacture profiles not only with regrinds in virgin window PVC-u, but also exclusively with lead-free PVC with “green” stabilisers based on calcium and zinc.
