Structural Glazing Lumira
Xtralite recently introduced Lumira technology, combining impressive thermal, light transmission and acoustic characteristics.
Lumira is made with translucent aerogel granules which fill clear polycarbonate multi-wall rooflight constructions, allowing light to pass through whilst serving as a highly effective thermal insulation. The extremely small pore size means that air molecules collide with the silica lattice, rather than each other, transferring energy to it, substantially limiting heat conduction and retaining heat inside.
Lumira provides vastly improved insulation performance with U values for a triple-walled rooflight reduced from 2.4W/m²K without Lumira to 1.3 W/m²K with the new technology.
Lumira also offers excellent light transmission with diffusion giving a shadow less light quality, as well as a 25% reduction in sound transmittance (at 1,000Hz frequency).
X-Emplar is Xtralite’s new sheer plane rooflight system that offers an overall Ud Value of just 1.1W/m2K.Read more
