Innovation Yields Big Picture Value Proposition as Market Driver
The value proposition is not just in delivering affordable highly thermal resistant windows, but how they eliminate up to 7 sf of header, jack & cripple stud material & cost that accompanies every 13 sf of the typical conventional window. Detailed preliminary calculations show that the windows ‘marry’ well with 24”on-center wall framing in creating affordable Near & Net Zero Energy Buildings:
- An R5 egress window in 2x6s,24”oc costs the same or less than a 3’x6’ low-e/argon window in 2x4s,16”oc: architects & builders can double envelope energy efficiency for the same or less cost as conventional construction.
- An R9 window in 24”oc advanced framing yields PassivHaus performance at a negligible .5-2% cost premium, enabling wide adoption.
- NZEBs, including rooftop solar can be built for a 6-8% cost premium, presenting a ‘holy grail’ for AFFORDABLE, routine & commonplace NZEBs.
