Electricity, insulation, and economics came together in a short span of time to shape how we live and work. Before electricity, big glass windows were a vital evil. We needed natural light to see, even though glass allowed heat to escape in the winter and invade during summer. With electricity and artificial light, that lack of insulation was too costly, and new buildings relied more on non-glass materials.
In 1934, the Libby Owens Ford Glass Company patented an insulated glass called Thermopane. Competitors all picked up the insulated glass, builders could eventually control electrical costs while keeping the aesthetic and natural light of large glass windows and doors.
Architects started blending rooms, breaking the barrier between inside and outside, delivering workspaces with breathtaking views, and giving us the landscape we see today.
