InVert™ Self-Shading Windows use smart thermobimetal inside a standard window cavity to dynamically block solar heat gain and reduce our reliance on energy. Using zero energy and no controls, the individual pieces respond to the sun and curl to block solar radiation from entering the building using up to 15% less air conditioning and reducing greenhouse gas emissions. InVert retains high levels of natural daylighting and full-color spectrum-both essential to human wellness-by using no film on the glass. Its magical beauty keeps humans in tune with nature and our greater ecological environment.
