Certification
Certified to North American standards
Our GH 80 Tilt & Turn window is certified by CSA Group to the North American Fenestration Standard (NAFS), including the Canadian Supplement. Canada's building code requires windows to meet both. It was independently tested for wind pressure, water penetration and air leakage.
- AAMA/WDMA/CSA 101/I.S.2/A440-17 (NAFS)
- CSA A440S1:19 Canadian Supplement
- CSA A440.2-19 (energy performance)

Tested performance
The numbers from the lab
| Test | Result | What it means |
|---|---|---|
| Performance class | CW-PG30 | Commercial-window class, performance grade 30 |
| Design pressure | ±1,440 Pa (±30.08 psf) | Wind load the window is rated to withstand, pushing in and pulling out |
| Water penetration resistance | 220 Pa (4.59 psf) | Pressure at which the window was tested against water getting through |
| Air infiltration | 0.05 L/s·m² | How little air leaks through when closed |
| U-factor | 1.44 W/m²·K | Heat transfer through the window; lower is better |
| Solar heat gain (SHGC) | 0.22 | Share of the sun's heat that gets inside; lower keeps rooms cooler |
| Visible transmittance | 0.38 | Share of daylight that passes through |
Results apply to the certified GH 80 Tilt & Turn window at the tested size. Source: CSA Group Certificate of Compliance No. 80180231.
Energy efficient
Keep the heat out and cut your cooling costs
Ordinary aluminum frames conduct the sun's heat straight into your home. Our thermal-break windows and doors, available on selected models, have an insulating barrier built into the frame that slows that heat transfer, so rooms stay cooler and your air-conditioning works less. That can mean lower electricity bills.
Ask us which models come with thermal break. Actual savings depend on your home, window sizes, glass and how you use air-conditioning.
Tested on our GH 80 Tilt & Turn window
SHGC 0.22
Only about 22% of the sun's heat striking the window gets through. The rest stays outside.
U-factor 1.44 W/m²·K
A low rate of heat passing through the whole window, frame and glass included.

Fabrication and installation
A window only performs as well as it is built and fitted. Our own team fabricates and installs, anywhere in the Philippines.
After-sales support
We stay with you after installation, so your windows keep performing the way they were tested to.
