Three-Performance Test: Air, Water & Wind
Ensuring safety, durability, and long-term protection through industry-standard performance testing.
What Is the Three-Performance?
The Three-Performance Test is a key industry standard that evaluates a window or door system’s ability to withstand weather conditions through three indicators:
Air Tightness
Reduces air leakage to improve energy efficiency and indoor comfort.
Water Tightness
Prevents rain penetration during heavy or wind-driven storms.
Wind Load Resistance
Ensures structural stability under strong wind pressure—critical for high-rise and extreme-weather regions.
Benefits:
Ensures long-term safety and structural reliability
Enhances weather protection and overall energy performance
Improves indoor comfort by minimizing drafts, noise, and moisture
Complies with international and regional building standards
How We Ensure Three-Performance Excellence
Our window and door systems are engineered to exceed industry requirements for air tightness, water tightness, and wind load resistance. Each component is optimized to deliver long-lasting performance in demanding environments.
Performance Breakdown
Air Tightness
Air tightness measures a system’s ability to block unwanted air infiltration through gaps in the frame and sash. Strong airtightness helps maintain stable indoor temperatures, reduces HVAC load, and improves overall energy efficiency.
Our systems use multi-layer sealing, precision frame tolerances, and high-elasticity EPDM gaskets to ensure minimal air leakage.
Water Tightness
Water tightness determines how well a window or door prevents rainwater penetration under pressure.
Our systems incorporate pressure-equalized chambers, optimized drainage paths, and full-perimeter seals to keep interiors dry, even during heavy storms.
Wind Load Resistance
Wind load resistance reflects the system’s structural ability to withstand positive and negative wind pressure without deformation, sash disengagement, or glass failure.
Our solutions use reinforced aluminum profiles, thick-wall cavity structures, and high-strength corner connectors to ensure stability in extreme conditions.

Frequently Asked Questions
Find clear answers to common questions about system performance, customization, installation, and project support—helping you select the right solution with confidence.
What does the Three-Performance Test include?
It covers air tightness, water tightness, and wind load resistance — the core weather performance indicators for windows and doors.
What standards do your products comply with?
Our systems can be tested according to ASTM, EN, AS/NZS, and CSA standards depending on your region.
Does frame material affect the Three-Performance results?
Yes. Thermal-break aluminum frames with multi-chamber structures offer superior strength and sealing capability.
Why is air tightness important?
Better airtightness prevents air leakage, improves energy efficiency, and ensures stable indoor comfort.
How is water tightness measured?
Through pressurized water infiltration tests that simulate heavy rain and wind conditions.
