Window World announced today that its windows have earned the  Good Housekeeping Seal for the 11th consecutive year.

The Good Housekeeping Institute also granted the seal to Therma-Tru doors sold by Window World.

“We were impressed with the large variety of designs that Window World’s windows and Therma-Tru doors offers, providing consumers with a wide range of options,” says Good Housekeeping Institute chief technologist and director of engineering Rachel Rothman, who oversaw the testing. “Coupled with weather resistance and durability properties, you can find exactly what you need for the project and location at hand.”

Good Housekeeping commended Window World windows for their weather resistance and durability, noting that the large variety of designs gives consumers a wide range of options. The institute validated the performance of Window World’s Therma-Tru doors, saying they exhibited great durability, moisture resistance and insulating properties. Good Housekeeping also found Window World’s siding system to be effective in resisting extreme-force winds in a lab testing environment and color fading from sun exposure.

“Year after year, Good Housekeeping validates the quality and strength of Window World windows with the Good Housekeeping Seal,” says Window World chair and CEO Tammy Whitworth. “We’re incredibly proud of all our products. Receiving the Good Housekeeping Seal for our siding and Therma-Tru doors, as well as our windows, verifies the quality of everything we offer our customers.”

The Good Housekeeping Institute evaluates thousands of products each year to test safety, quality and value. To prove its confidence in the products it endorses, the institute provides a two-year limited warranty for consumers on every item bearing the Good Housekeeping Seal.
