TM 77N is an advanced, next-generation window-door system designed for modern construction. It combines energy efficiency, production efficiency, and environmental care, making it an ideal solution for various types of structures.
The doors in the TM 77N system not only offer high thermal and acoustic insulation but also increased security with RC2 burglary resistance. They feature modern design and the ability to be customized to the investor’s individual needs, offering a wide range of configurations and finishes.
The TM 77N system is equipped with new gaskets that have reduced prefabrication time by 20%, significantly increasing production efficiency. Additionally, these innovative gaskets are fully recyclable, contributing to sustainable development.
The TM 77N system is available in three variants, allowing perfect adaptation to different types of buildings and individual investor needs:
TM 77N ST
TM 77N I
TM 77N HI+
TM 77N ST: Standard version with a central gasket and thermal inserts.
TM 77N I: Enhanced insulation with an additional central gasket and insulating foam.
TM 77N HI+: Best thermal performance with enlarged insulating inserts.
TM 77N ST
TM 77N I
TM 77N HI+
Each variant is designed to ensure optimal thermal efficiency within its category, leading to savings and increased comfort for users.
*WT2021 – In accordance with European Directive 2010/31/EU, WT2021 is an update to the Technical Conditions for buildings and their location, effective from January 1, 2021. These changes introduce more stringent standards for the energy efficiency of buildings, including higher requirements for the thermal insulation of partitions, window and door joinery, as well as ventilation and heating systems. The goal of WT2021 is to increase the energy efficiency of buildings, reduce CO2 emissions, and promote sustainable construction.
