Alpen HPP receives .10 U-value rating from NFRC

We are very proud to announce the availability of a commercially viable full-frame fixed window package capable of providing an R10 insulating value.

Following independent testing by National Certified Testing Laboratories and subsequent certification by the National Fenestration Rating Council (NFRC) in June, our new Zenith Series ZR10 double-film fixed picture window design (NFRC Certified Products Database number ALP-M-10-00120-00001) was verified to deliver a .10 U-Factor.

Earning an NFRC rating, additionally, makes the Alpen ZR10 window eligible for the U.S. Department of Energy’s (DOE) ENERGY STAR® certification, and a candidate for ENERGY STAR Most Energy Efficient 2016 recognition.

According to the DOE’s R-value scale, which is a part of its Office of Energy Efficiency and Renewable Energy (EERE) Building Technologies (BT) Program, this performance data equates to an R10 insulating factor.

The BT Program’s R-value rating scale translates the NFRC’s U-factor to a thermal resistance number, with, for example, an R6 window indicating a U-factor of 0.17, and an R10 window representing a 0.10 U-factor.

“Achieving R10 performance represents a major accomplishment – beyond Alpen as a company and for the fenestration industry at-large,” said Alpen CEO Brad Begin.

“With the goal of developing a market accessible R10 window by 2020, the DOE’s Building Technologies Program has funded millions of dollars in research and development for high performance building shell technologies, which has led to billions invested both publicly and privately over the last 15 years.

“Despite a great deal of work and commendable advancements, hitting the mark on ‘low incremental cost’ and crossing the commercialization chasm has remained a challenge for the fenestration industry,” Begin continued.

“Alpen’s Zenith Series ZR10 fixed picture window has now overcome the challenge as both a validated R10 performer and a market-ready product – truly surpassing the DOE’s goals for bringing a market accessible R10 window technology to the U.S. by 2020.”


Praise from window authorities

“More than 20 years ago, and well after the introduction of low-E coatings, LBNL completed a series of research studies that clearly identified need for improving the thermal properties of windows as part of a comprehensive national energy conservation strategy,” recalled Stephen Selkowitz, former leader of the Windows and Daylighting Group at Lawrence Berkeley National Laboratory (LBNL).

“We outlined several aggressive technology development pathways that could result in windows with lower energy costs than a highly insulated wall. As climate and orientation vary widely across the U.S., we also noted requirement of a variety of window performance properties to optimize performance in different regions.

“We are delighted to see Alpen bringing to market what can likely meet – if not exceed – our original Net Zero envelope performance criteria.”

“While we were confident of our analyses and test results, window manufacturers have remained challenged with developing a commercially viable solution – until now,” Selkowitz continued.

“We are delighted to see Alpen bringing to market what can likely meet – if not exceed – our original Net Zero envelope performance criteria.

It was also exciting to note their use of the LBNL’s WINDOW and THERM simulation tools, developed and updated thanks to ongoing support from the U.S. Department of Energy, to optimize design features such as glazing layers, coatings, gas fills and frame design.

As passive house performance requirements continue to increase across the U.S., it’s great to see the growth and success of a domestic company like Alpen, which is wholly focused on development and production of cutting-edge high-performance building shell technologies.”


 Alpen products are defining high performance

The Alpen ZR10 rounds out the company’s existing range of Zenith Series 1025 and 925 double-film high-performance window designs, engineered to provide super insulating properties in both heating- and cooling-dominant climates.

At-large, the Zenith Series is one of four series of window and door systems that comprise the current Alpen product offering.

In total, Alpen has updated NFRC ratings for all of the company’s previously NFRC certified window and door products this summer, as well as achieved a new NFRC rating for the Alpen Zenith Series ZR10 fixed window.

Begin shared that several additional product rollouts are planned by the company during the remainder of 2016.

“As a company, Alpen has worked diligently over the years in advancing toward an American-made solution to the DOE’s Energy Efficient Building Technology Roadmap challenge, and along the way we’ve made incredible breakthroughs while developing some of the highest-performing windows and glass products the world over,” said Begin.

“We did this by putting our heads down, never taking no for an answer, and realizing that the stakes were high and the payoff well beyond that of monetary value – especially without the support of any Federal grant funding, even to this very day. “

“Alpen’s proprietary and unique combination of materials and components have allowed us to create a suite of products that start at performance levels where typical fenestration products level off, and we couldn’t be more proud of what has resulted from an unrelenting work ethic right here in Boulder County,” Begin continued.

“It’s this kind of dedication that has led us out of the lab and onto the manufacturing floor with what we believe to be the industry’s first commercially available R10 window product.”
