Precast and Window Integration Advances

July 21, 2022

AltusGroup has been working closely with Innovation Partner Kawneer on developing a standard way to integrate windows into punched CarbonCast panels. Delivering pre-glazed exterior wall panels to the job site can simplify and accelerate construction, speed dry-in, improve envelope performance and enhance enclosure quality.

To verify performance of the CarbonCast panel with an integrated Kawneer window, AltusGroup engaged Intertek’s York, Pa., facility for testing in accordance with ASTM E283/E283, ASTM E331 and ASTM E330/E330M. (Intertek Report No.: M9610.01-109-44.) The panel performed exceptionally well.

Design Pressure: ±2560 Pa (±53.47 psf)
Air Infiltration at 300 Pa (6.27 psf): <0.1 L/s/m2 (<0.01 cfm/ft2)
Water Penetration Resistance Test Pressure: 580 Pa (12.11 psf)
Uniform Load Structural Test Pressure: ±3840 Pa (±80.20 psf)

Additional development is in the works across the AltusGroup member roster to refine design and connection details to deliver an integrated panel that is efficient to manufacture, ship and install.
