PORASPHERES - The world's first Hollow Glass Spheres made from 100% recycled glass. Lightweight, durable, with a closed surface structure - and, unlike PORAVER, with a single cavity.
PORASPHERES Hollow Glass Spheres are the further development of the proven PORAVER lightweight aggregate and the result of years of research work.
In contrast to PORAVER, PORASPHERES do not have an internal multicellular structure, but a single cavity. This structure - in conjunction with a closed surface - results in a further significant reduction in water absorption, a lower grain density and, compared to the axial compressive strength of PORAVER, an extremely high isostatic strength.
Like PORAVER, PORASPHERES are made exclusively from recycled glass, binders and blowing agents and have the same environmentally friendly properties as PORAVER, which has been tried and tested worldwide for decades.
Product highlights from PORASPHERES
