Fulham Prep school SonaSpray fcx installation

I am writing to congratulate your company for the success achieved in the reduction of the noise level in our school dining room when 200+ children are having their lunch.

Prior to the application of SonaSpray, the noise level was deafening, and now it is possible to talk to ones neighbour in a normal voice when lunching at the staff table...
