Sierra Pacific Windows has unveiled a new line of architectural wall systems, which offer architects more freedom to design with expanded use of glass, clean straight lines, and transparency between indoors and outdoors. With their all-wood interiors and load-bearing structural integrity, the new line, in many cases, can eliminate the need for steel beams. The walls are tested to ASTM standards for air and water infiltration, as well as structural wind-load performance. Additionally, they meet today’s energy standards for heat loss and solar heat gain.
