Solatube Dome is made of injection molded high impact acrylic/polycarbonate with UV inhibitors. The patented LightTracker® & Ray bender 3000® technology harnesses maximum daylight during the early morning & late evening hours to deliver uniform light throughout the day. The Spectralight Infinity tubing in Solatube has a spectral reflectivity of 99.7%. The highest in its class. The proprietary Cool Tube technology in Solatube prevents I/R infiltration and ensures no additional Heat Load on the building. The engineered prismatic diffuser in Solatube has a number of micro-prisms which diffuse the light over a wide area underneath. Different Diffuser options available for different applications. No. of Solatube DS required are much lesser for the same room size as compared to competitors. Overall project cost lesser.
