Premiered at this year’s Fensterbau/Frontale, not only does this new addition exhibit a Uf value of 1.4 W/(m²K), an outstanding thermal insulation for lift/sliding doors, but its small installation depth of 76 mm makes it ideal for renovations.
Nevertheless, thanks to its stable five chamber design throughout its length, the system can take glazing up to 50 mm thick and provides the static prerequisites for elements up to 2.6 metres in height.
A high passage of light is ensured by the slender sight lines – 65 mm at the casement, 100 mm at the sash, and 103 mm at the centre closure – and its elegant character is enhanced by the slender play of lines.
In addition to the classical version there is also the “lux design” sash, offering a particularly slender sight line of 40 mm for even larger glazed areas and higher solar energy gains.
The premium quality of PremiDoor 76 finds testimony in its ease of handling, reliable function, and the pleasantly smooth and quiet run of its sliding sashes.
The benefits of this flush-mounted system are rounded off by the op-tional combinations with upgrade technologies like AluClip and the huge design potential presented by wood grain, plain, and metallic colour laminates.
With the changeover to the new 76 mm system platform, PremiDoor 76 will become the successor system to the PremiDoor 70 lift/sliding door.
Moreover, profine offers in this growing premium segment its PremiDoor 88, a lift/sliding door with 88 mm installation depth and an excellent thermal insulation value of Uf = 1.2–1.3 W/(m²K).
