Strength, versatility and a suitability for larger homes, place the expansive Pacific41™ system from Altus® Window Systems at the centre of New Zealand’s architectural window & door market

Generous thinking

The Pacific41™ system is preferred for larger family and architecturally designed homes exhibiting large expansive windows and doors.

Aesthetic appeal, functionality, increased glazing capacity and strength of internal components means the Pacific41 system is perfect for taking the next step up for your aluminium joinery.

Versatile in the extreme

The Pacific41 system can accommodate almost any combination of window and door configuration. 

Products such as the innovative Foldback™ Bifold, the iconic Ranchslider™ with optional Levelstep™ and the premium Euroslider™ are all available within the system. 

Seen in all the right places

The Pacific41 system is suitable for upping the looks and functionality of architectural design across multiple market segments.

These include: Mid-Level Residential to High End Architectural homes, Multi-residential, Light Commercial Applications, School Builds, Exposed Architectural Homes and A&A (Additions and Alterations).

All products within the range allow for double glazed insulated units up to 30mm thickness, a must for larger format windows and doors. 

Modern and sleek flat faced frame profiles are available across all product types with window sashes available in flush and flanged variants. 

Flat faced frames seamlessly integrate with both our Tasman35™ and Atlantic48™ systems, where required.

Door unit sizes for the Pacific41 System can be up to 2.6m* high (higher spans can also be achieved) and have sliding panels weighing up to 160kg and hinged panels weighing up to 60kgs, both offer wide glass openings for impressive uninterrupted views and access.
