Integrity Achieves Milestone with AAMA 624-10 Certification


Company is first & only to achieve 623-10 and 624-10 with completed requirements for 625-10

FARGO, N.D. – All products manufactured by Integrity from Marvin Windows and Doors are made with Ultrex®, a pultruded fiberglass that is eight times stronger than vinyl, three times stronger than wood/vinyl composites and as strong as steel. And now, Ultrex’s coating is the first and only to achieve 624-10 verification from the American Architectural Manufacturers Association (AAMA). The AAMA 624-10 designation specifically refers to Voluntary Specification, Performance Requirements and Test Procedures for High Performance Organic Coatings on Fiber Reinforced Thermoset Profiles.

The toughness of Ultrex is legendary, as it resists rotting, warping, fading and chipping to maintain its beauty. Part of this durability comes from its coating. This patented system protects the Ultrex and allows its natural material characteristics to perform at their highest level. Ultrex is currently the first and only finish to have achieved 623-10 and 624-10 verification and to have completed the lab requirements for 625-10.

AAMA 624-10 certification means that the finish has passed numerous, rigorous tests, including:

  • Dry Film Thickness of >3.0 mils (minimum requirement is 1.2 mils)
  • Dry Film Hardness of 2H (minimum requirement is F)
  • Dry, Wet and Boil Adhesion testing with no loss of adhesion
  • Direct Impact with no film removal
  • Abrasion Resistance
  • Chemical Resistance tests of muriatic acid, mortar & nitric acid without blistering
  • Detergent Resistance test with no loss of film adhesion and blistering
  • Window Cleaner Resistance test with no loss of film adhesion and blistering
  • Humidity Resistance test with no blisters
  • Cold Crack Cycle test with no cracking, adhesion loss or detrimental effects
  • Three outdoor weathering tests

These tests simulate the harsh conditions that a finish will encounter throughout the life of the window or door. Passing these specification tests and achieving AAMA 624-10 gives Integrity independent verification that the Ultrex finish is best in class among fiberglass products.

“Being the first and only finish to have achieved AAMA 623-10 and 624-10, and completing the lab requirements on 625-10, is a great honor,” said Becky Felling, Director of Marketing at Integrity Windows and Doors. “We’ve always known how durable our finish is, but it’s great for our customers to have independent corroboration. It truly shows that when you buy an
Integrity window or door, you’re getting the whole package: beauty, durability, performance, outstanding service and support, and Integrity’s unmatched 10-business-day delivery.”
