E90tt system is made with a broken thermal bridge, basic profile depth 90mm. The system is used to make entrance doors with one-sided and double-sided hidden wings for internal opening. The termination of the thermal bridge is achieved with polyamide strips 34 mm wide for the frame and wing.
Specially designed polyamide on the wing reduces deformation of the door due to temperature expansion or contraction of the panel. The new insulating profiles consist of two interwoven parts which, in case of different linear expansion between the aluminum components, move against each other.
The sealing between the frame and the wing is made with EPDM outer and central seals and three extruded TPV seals on the inside for a hidden wing on both sides.
