ALU 60mm, a door with excellent insulating and sealing qualities. The fully glazed aluminium panels with vaccum glass and an interrupted thermal bridge ensure the best possible thermal insulation and soundproofing at all times.
The Helix and S600 High speed doors which open 6 x faster than sectional doors manage to save much energy due to their insulation and speed. These doors were created for heavy use. The Helix door offers a revolutionary innovation: the spiral system is space-saving and protects the lamellas from wear and tear.
Thanks to excellent technology, an entrance door with recessed hinges, an interrupted thermal bridge and a low 22mm transition threshold can be built into the door.
Alpha Portas offers 12 standard RAL colours without charge, applied through powder lacquering on micro-lined profile panels.
