Westlake Royal Window Solutions Products Meet New Energy Star Requirements
New requirements for Energy Star-rated windows go into effect Oct. 23, 2023, and Westlake Royal Window Solutions, a Westlake company, is ready to serve customers with a range of options across all three of its window collections.
About Version 7.0 and Westlake's offerings
Under the Energy Star Version 7.0 Residential Windows, Doors, and Skylights Final Specification, finalized Oct. 20, 2022, windows, doors and skylights must meet higher benchmarks of energy efficiency to earn the Energy Star certification and label. This includes more stringent requirements for U-factor and solar heat gain coefficient ratings in each of the four Energy Star climate zones and as well as adjustments to those zone boundaries.
Westlake Royal Windows offers several window and sliding glass door products that meet the new Energy Star 7.0 requirements in the Southern, South-Central and North-Central climate zones in which the company’s windows are sold. Qualifying products are available within all three of Westlake’s window collections, Magnolia, Krestmark and Legacy, and in standard, impact-resistant and sound transmission class grades.
What Westlake says
“As the Department of Energy notes, windows account for just 10% of an average home’s surface area but lose 35% to 45% of a home’s heat in winter. Therefore, it’s essential that we continue to push the envelope with window and glass technology to help reduce energy waste while decreasing a home’s carbon footprint and energy costs,” says Alex Bradaran, general manager, Westlake Royal Window Solutions. “Westlake Royal Windows is pleased to offer an array of options certified under Energy Star Version 7.0 through all four of our manufacturing facilities. As such, we have a solution to meet each customer’s and each project’s unique aesthetic, performance and energy efficiency needs.”
