the power of diffusion
Kalwall has been leading the diffuse daylighting revolution for more than 60 years with its high performance translucent building systems. Unlike transparent glazing materials, Kalwall scatters visible light waves providing even, diffuse daylighting to interior spaces no matter the position of the sun. Kalwall also meets target daylight levels while transmitting lower percentages of visible light, when compared to conventional vision glazing, due to a process called lambertian diffusion. This phenomenon is also why artists have long preferred northern light which is naturally diffused by the atmosphere. Kalwall provides museum-quality daylighting™ that is balanced without areas of high contrast, hot spots or glare eliminating the need for additional light redirection or shading devices on all elevations of the building. Kalwall’s power to diffuse daylight also means that light penetrates much deeper into interiors, reducing artificial light usage during the daytime.
