RT-74 is a casement system with thermal break and uses extruded aluminium semi-profiles joined by 34 mm polyamide bars and reinforced with glass fibre which grant maximized insulating properties and high mechanical resistance.
This system has 73.6 mm fixed frames and 81.7 mm mobile frames which allow applying straight and rounded beads with maximum filling of 55 mm and the possibility of internal or external opening.
RTA-74 has two channel possibilities, the European chamber and a 16 channel which allow a vast range of accessories to be applied and therefore very different solutions can be obtained.
Seals used by the system are in EPDM and the central seal and the internal casement seal are coextruded which grant optimal airtight, thermal and soundproof performances.
The RT-74 SUPERTHERMIC system meets EC marking standards. To verify the said compliance, it was submitted to typical initial tests at a certified laboratory.
