Radiant heating using flexible film, natural wool insulation for walls and windows plus reflective window insulation is now the focus of Warm Rooms brand of Powers Design Company. After years in residential design/build we are now promoting products that conserve energy, materials and resources. https://www.facebook.com/warmroomsspace/ Images of many homes with installed Warm Rooms materials can be found on our Facebook page with a shopping link to Amazon. Please visit and share. Custom homes, remodeled homes (especially those built in 1950- 80 with electric ceiling heating and no ducting), tiny houses, houseboats, trailers - all appropriate spaces for flexible film radiant ceiling and floor heating. Radiant ceiling heating is desirable if the architect wishes to avoid fitting in ducting, or a lowered heating bill is desired, or the homeowners desire a healthier home with no heated air blowing dust around and causing drafts.
