Sam Pardue Built a Climate Business From a Flickering Candle
A draft moved the candles in his 1906 Portland house. The fix led from a failed magnetic prototype to a patented insert, a precision-measurement system, and a company built around keeping good windows in place.
The $30-a-Foot Fix for People Who Hate Their Windows - but Refuse to Rip Them Out
Indow built a climate-tech business around an unglamorous idea: keep the old window, measure it obsessively, and press a precisely cut acrylic panel into place. The first magnetic prototype failed. The stripped-down version became the product.
NxLite
NxLite (formerly 3E Nano) makes next-generation, transparent energy-control coatings for glass and lightweight polymers. Spun out of the University of Toronto in 2015, the company's patented nano-thin, low-emissivity and solar-control coatings are air-stable and can be applied to glass, acrylic (PMMA) and polycarbonate, cutting the heat that windows gain or lose. NxLite sells to window and door makers, refrigeration and transportation manufacturers, and building-retrofit customers, and runs a 45,000-square-foot Advanced Innovation & Manufacturing (AIM) Center in Canton, Michigan.
