Pella® 350 Series Vinyl Windows Earn ENERGY STAR® Honor

Pella's Top Energy-Saving Product Line Receives 'Most Efficient Products' Title

PELLA, IA--(Marketwired - January 02, 2014) - Pella 350 Series premium vinyl windows earned the 2014 ENERGY STAR Most Efficient Products designation from the U.S. Environmental Protection Agency (EPA).

"Whether you're remodeling your home or building a new one, Pella 350 Series windows offer exceptional energy efficiency with a more premium look than other vinyl windows," said Sandi Robinson, Pella's integrated marketing specialist.

"This product is quickly becoming a favorite Pella window line for homeowners, builders, architects and contractors who value a stronger, more durable vinyl window with outstanding energy-saving features," she said.

Second year for designation

This is the second year that Pella 350 Series has earned the newer rating, Most Efficient Products, which identifies the most energy-efficient ENERGY STAR-qualifying products in the United States market at the time. Pella Windows -- which earned a U.S. ENERGY STAR Partner of the Year 2013 award -- met strict energy requirements to earn the Most Efficient designation, including:

  • Meeting the North American Fenestration Standard/Specifications (NAFS) performance grade greater than or equal to 15
  • Achieving a U-Factor of less than or equal to 0.20
  • Attaining a Solar Heat Gain Coefficient (SHGC) requirement specified based on four U.S. climate zones
