SOLATEX is an extra clear patterned glass formed with a smooth pattern on both faces. This ensures the highest energy transmission over the whole solar spectrum.

Combined with the excellent durability of glass, SOLATEX is the product of choice for photovoltaic modules (crystalline and CIGS, where its pattern allows for an easy lamination) and for thermal collectors (for which SOLATEX is labelled U1 from SPF). Through its pattern, SOLATEX also ensures non-blinding reflection and a better aesthetics to the solar modules.

SOLATEX conforms to EN572 and is delivered fully tempered as per EN12150. It can be supplied with AGC Solar Plus Anti Reflective Coating (SPARC).
