The M65 TB series allows the manufacturing of large openings with a streamlined visual impact and maximum stability. M65 TB profiles have a section in view of only 18 mm and are made from solid 2 mm thick sheet metal, with thermal break. The depth of the profile, from 65 to 72 mm, is designed to achieve high moments of inertia and to accommodate the latest generation of insulating glass. The PA 6.6 polyamide insulating core guarantees excellent performance in terms of energy saving.
