The 41Architectural™ system will be superseded from September 2022 to the Pacific41™ system.

Our beloved 41Architectural™ system will be no longer available from September 2022. For joinery required after this date, please click the link to have a look at our new Pacific41™ system.

The 41Architectural™ system is a residential and Architectural aluminium joinery range that is based on the AllSeasons™ system profile. It offers the same square face design, structural strength and the Altus proprietary connection systems, but without the thermal break.


  • Square flat faced frame with a 19mm flange, accommodating a flush sash.
  • Fixed glazing, 41mm glazing platform (IGUs up to 30mm).
  • Provision for up to 24mm IGUs in pocketed sashes and 30mm in beaded sashes.
  • A range of mullions and transoms to add strength to cope with higher wind loads.
  • 50mm wide panels for greater strength and height on Hinged and Bi-fold Doors.
  • The two-piece Stacker Door design means you can add multiple panels.
  • The outside sliding door wide track means larger panels can move freely on the track and provides a cleaner surface appearance.
  • Door stiles are designed for Mortise locks sets to improve security.
  • Hinged door panels include torsional stiffening blocks for stronger panels.
  • Optional wide stiles and rails.
  • Standard and heavy duty coupling bars available.
