In coastal and high-rise locations, windows must resist strong, sustained wind pressure and wind-driven rain. SKATE high wind-load windows use heavy-duty profiles, glass sized to your design pressure and a three-chamber drainage design.
Built for Wind Pressure
- Wind load resistance of 5.0 kPa (grade 9, the top class of GB/T 31433) on our 75 tilt and turn, 95 and W110 series
- Safety test (Pmax) at 7.5 kPa, positive and negative pressure
- Heavy-duty 6063-T5 aluminum profiles with up to 2.0 mm walls (110H series)
- CNC-machined joints to ±0.05 mm, which our tests show improve wind resistance by about 15%
- Seamless welded corners with joint strength of at least 85% of the profile

Certified Rating in Australia
Our 76M tilt and turn window is certified to AS 2047 (StandardsMark SMK41686) with an SLS design wind pressure of 800 Pa and ULS of 2000 Pa at 1500 × 600 mm.
FAQ
Q1: What wind pressure can your windows take?
A: It depends on the series, size and glass. Our 75 tilt and turn, 95 and W110 series tested at 5.0 kPa (grade 9) with a 7.5 kPa safety test; send us your design pressure and we will recommend the right configuration.
Q2: How do you choose glass for high wind loads?
A: We start from pane area (5 mm under 2 m², up to 12 mm for 5–6 m²), then check each pane against your project's design wind pressure and recommend laminated glass for exposed sites.
Q3: Are your windows certified for Australian wind conditions?
A: Yes. Our 76M tilt and turn window is certified to AS 2047 (StandardsMark SMK41686) with an SLS design wind pressure of 800 Pa and ULS of 2000 Pa at 1500 × 600 mm.
Q4: How do welded corners help in strong winds?
A: Our seamless welded corners reach a joint strength of at least 85% of the profile, and CNC-machined joints to ±0.05 mm improved wind resistance by about 15% in our tests.
Q5: Will strong wind push rain into the window?
A: Our three-chamber design drains water that enters the outer chamber. Our 75 tilt and turn, 95 and W110 series showed no water leakage at 700 Pa, grade 6, the top class of GB/T 31433.
