Pella Corporations’ CW-rated Architect Series® line of wood windows¹ has been expanded to include the new Monumental Hung window. This addition to the line means Pella now provides a complete portfolio of CW-rated wood products.
“Pella EFCO Commercial Solutions has always had a full breadth of products and services to meet the design intentions of architects and engineers,” said Stacy Seelye, Pella product specialist. “The new Monumental Hung window is a welcome addition to the available choices in the market.”
Available this summer, architects and builders can now specify Pella for virtually any low- to mid-rise commercial project, especially for building retrofits, where historical accuracy and energy efficiency can be equally important.

The Architect Series Monumental Hung window features the following product enhancements:

• Increased size range up to 72” x 144”
• Sightlines and feature additions for improved aesthetics and historical accuracy
• CW30 to CW50 available

• Class 5 (AAMA 902-99) balances available

 CW-rated products
Architect Series products, with a CW-rating can be used in a larger number of non-residential and multifamily building applications that may require larger sizes, higher wind loading requirements, limits on deflection, durability of hardware and resistance to water infiltration.
Compared to R- and LC-rated products, enhanced performance features of CW-rated products based off of the AAMA 101 Standard include:

• Higher overall performance grade
• Higher levels of resistance to wind pressures as measured by design pressure
• Larger gateway test sizes, meaning larger windows have been tested to meet higher performance criteria
• Increased resistance to water infiltration
• Less deflection of sash and frame at design pressures due to wind
• More durable hardware for heavy use
