Wausau, Wis. — Nov. 18, 2014 — Recognizing Wausau Window and Wall Systems’ industry leadership and expertise, the National Fenestration Ratings Council (NFRC) has approved the company as a Manufacturer Approved Calculation Entity (ACE) Organization under the Component Modeling Approach (CMA) Certification Program.
NFRC is the global leader in delivering energy and related performance ratings and certification for fenestration products and systems. Many of Wausau’s products are listed in NFRC’s Certified Products Directory, including operable and fixed windows, sliding glass doors, and unitized curtainwall. In 2009, Wausau’s John Callback and Tom Mifflin also were among the first CMA software tool (CMAST) users who earned ACE certification.
“ACE certification keeps us at the forefront of emerging industry trends in energy-efficiency. Based on our experience and knowledge, we can provide our customers with the expertise and comfort to decipher new energy-code requirements,” Kolbeck said. “Manufacturer ACE Organizations can generate code-mandated CMA Bid Certificates and Label Certificates for framing systems included in the NFRC CMAST library, no matter which glass is selected. This helps ensure responsive and accurate thermal performance verification on a project-to-project basis.”
Mifflin added, “Model Energy codes like ASHRAE 90.1 and IECC [International Energy Conservation Code] reflect best practices for non-residential applications. Wausau recommends specifying U-Factor and SHGC requirements by citing the values used in the default, prescriptive, or performance compliance path option employed during permitting. Performance of specific Wausau frame-glass combinations can be obtained from the NFRC Certified Products Directory or CMA Bid Certificate.”
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 California’s Title 24, to determine compliance. In addition to 24 active product listings in the NFRC Certified Products Directory for factory-glazed fenestration, Wausau has 16 Framing Product Lines in the CMAST library, and new product variations are added frequently.
Nationally recognized for its innovative expertise, Wausau Window and Wall Systems is an industry leader in engineering window and curtainwall systems for commercial and institutional construction applications. For more than 55 years, Wausau has worked closely with architects, building owners, and contractors to realize their vision for aesthetic beauty, sustainability, and lasting value, while striving to maintain the highest level of customer service, communication, and overall satisfaction. Wausau is a part of Apogee Enterprises, Inc., a publicly held, U.S. corporation.
