How do AAW architectural windows meet NZBC Clause H1 5th edition compliance in Wellington Zone 4?

AAW Series 800 windows feature advanced 34mm polyamide thermal struts paired with SunCool Low-E double or triple glazing with 90% argon gas fill, delivering typical whole-window R-values between R0.51 and R0.78, easily exceeding the mandatory NZBC H1 Zone 4 minimum of R0.37.

What wind zone classifications under NZS 4211:2008 do AAW joinery suites support?

AAW extrusions are engineered and tested for High (H), Very High (VH), Extra High (EH), and Specific Engineering Design (SED) wind pressures, with water penetration resistance verified up to 900 Pascals for severe Wellington coastal slopes.

Why is 25-micron marine anodising recommended for coastal Wellington properties?

Properties located within 500 meters of the coastline in Eastbourne, Seatoun, or Kāpiti experience continuous salt-spray aerosol. 25-micron marine hard-anodising provides a thick electro-chemical barrier that prevents corrosion, pitting, and finish breakdown for 25+ years.
