Liana began as a manufacturer of door and window gaskets and, over the years, has built up extensive experience in the design and production of extruded technical profiles for windows, doors, PVC and aluminium systems, and glass facades. The sector’s continuous evolution has led us to develop high-performance plastic solutions capable of meeting the insulation, sealing and durability requirements of modern closure systems.

 

Our in-depth knowledge of thermoplastic and polyurethane materials enables us to manufacture custom gaskets and made-to-measure profiles for door, window and curtain wall manufacturers. Each solution is designed to ensure high technical performance, dimensional accuracy and seamless integration with the system in which it is installed.

Some examples of application fields.

Our solutions are used for wooden, PVC and aluminium doors and windows, entrance doors, sliding systems and structural glazing. The profiles and gaskets developed by Liana help improve thermal and acoustic insulation, weather protection and long-term reliability, meeting the varied design requirements of door and window manufacturers.

Some examples of our realizations.

Since 2001 we have been providing the wooden door and window industry with foam-core tri-extruded thermoplastic gaskets that are currently the highest quality solutions on the market.

Companies that produce doors and windows must guarantee good thermal breaks. We are able to identify the best solution for any kind of project.

Our long experience in the field of glass facades means we are able to provide high-performance thermoplastic and polyurethane materials.
