Front Line tm curtain wall systems provide exceptional performance to meet or exceed your projects design criteria. From low-rise to high-rise applications, PW251 is designed to meet a variety of conditions. PW251 is available in captured and butt-glazed systems.

Performance:
Test Method/Results
* Air infiltration test at 6.24 PSF (ASTM E283) | less than 0.06 cfm/ft2
* Uniform load deflection test (ASTM E330) at | +60/-60 PSF
* Water infiltration test (ASTM E331) at | 20 PSF
* Uniform load structural test (ASTM E330) at | +90/-90 PSF
* Thermal Transmittance (U-factor) = 0.43
* Condensation Resistance Factor = 66
