Four more Wausau associates earn NFRC ACE certification

Four more associates at Wausau Window and Wall Systems have earned a Certificate of Approval for successfully completing the National Fenestration Ratings Council (NFRC) Approved Calculation Entity (ACE) Training Workshop and passing all necessary examinations.

Wausau’s most recent ACEs include: engineering team leader, Jerry Habeck; research and development design engineer, Josh Cole; and architectural sales representatives, Brad Glauser and Gregg Tassone.Based in Washington state, Glauser serves design and building teams in Alaska, Oregon, Washington and northern Idaho. On the opposite coast, Tassone supports New York City and northern New Jersey.

As an NFRC ACE, each is qualified to carry out performance calculations of fenestration products for design support and final certification using the NFRC Component Modeling Approach (CMA). They join their colleagues, John Kolbeck and Tom Mifflin at Wausau, who were among the first to earn ACE certification in 2009.

In 2014, the NFRC also approved Wausau Window and Wall Systems as a Manufacturer ACE Organization. Many of Wausau’s products are listed in NFRC’s Certified Products Directory, including operable and fixed windows, sliding glass doors and unitized curtainwall.


“We are proud of all four of them for their accomplishments. With this knowledge, they are able to directly support architects and our customer’s project needs and keep Wausau at the forefront of emerging industry trends in energy-efficiency,” said Mifflin.

Through NFRC’s CMAST libraries of approved frames, glass and spacer components, users can configure fenestration products for a project, and can obtain a U-factor, solar heat gain coefficient and visible transmittance rating for those products. Performance values are then compared to the energy requirements of local codes, such as New York City’s Energy Conservation Code and Seattle’s Energy Code, to determine compliance.

Performance of specific Wausau frame-glass combinations can be obtained from the NFRC Certified Products Directory or the CMA process. In addition to 24 active product listings in the NFRC Certified Products Directory for factory-glazed fenestration, Wausau has many approved curtainwall, window and door products in the CMAST library, and new product variations are added frequently.

NFRC is the global leader in delivering energy and related performance ratings and certification for fenestration products and systems. Learn more at
