GLASIO is a porous material formed of thermally bonded particles of crystal glass. The panels are bonded by heat and do not contain any additives, such as fillers and binders. The material is a Czech product made of recycled glass.

GLASIO is an acoustic panel with the maximal acoustic attenuation at mid frequencies where the absorption capability exceeds 90% of the incident acoustic energy. These frequency bands (octave bands of 500Hz and 1 kHz in particular) are also essential from the perspective of speech intelligibility.

The panels can be produced in a bent shape and are available in various colours. The material is ideal for use in theatres, auditoriums, lecture halls, classrooms and in a number of other indoor spaces where acoustics and interior design are a priority.
