Our contribution

9.1.1. Optimize the acoustic quality of spaces

All the noise nuisances, including traffic, construction, and loud music, affect our quality of life and sometimes even our health. SageGlass can help reduce external noise and improve indoor acoustic comfort by combining two glasses of different thicknesses, or by adding a spacer specifically designed to optimize sound insulation. It's essential to note that for optimal performance, the glazing must be used on waterproof joinery with excellent acoustic properties. 
Also, by completely replacing the often noisy mechanical sunscreens, SageGlass eliminates an additional source of noise and distraction for occupants.
