Title: Novel Thermal-Break Development Enabling Breakthrough R7-Architectural Windows

Abstract

Arconic Inc., with their subsidiary Kawneer, undertook the challenge of developing a breakthrough R7 thermal performance Architectural-Grade Windows with Aluminum frames, and have successfully completed the challenge. A novel thermal-break system was designed, developed, and validated that enabled Architectural windows that achieved R7 thermal-performance to serve new and retrofit building and construction markets. The novel thermal-break technology is an innovative concept that incorporates a sandwich-type structure where foam is used as thermal-break material captured between two aluminum pieces creating a highly insulating frame system. It improved the Frame U-Factor by 20% and overall window U-Factor by 15% when compared to the best commercial window in the market today (Kawneer’s R5 OptiQ-Ultra Thermal Windows ). It has the potential to reduce ~2 Quad of energy used in Commercial buildings in USA. Achieving breakthrough R7 thermal performance advances the “state-of-the-art” and significantly raises the bar for commercial/architectural window systems where superior thermal performances don’t have to compromise with high structural performance, window frame aesthetics, longevity, or ease of maintenance. Successful deployment of these ultra-high insulating Architectural R7 windows would be a critical element of DOE Building Technology Office’s (BTO) goal of delivering 50% primary energy savings in the year 2030, relative tomore » the baseline energy consumption projected by the 2010 Annual Energy Outlook; taking us closer to net-zero-energy (NZE) buildings.« less
