Project Name: Thompson Elementary School, Bend OR Gypsorb Product: Special Stratum Completed: 2021 Using specially created Stratum panels, the architects produced both a beautiful design and excellent acoustical environment in this historic school building. GypSorb worked within the historical preservation parameters to create the best acoustic management solution while fitting into the required vintage appearance. Our sister company, PolySorb, supplied the PET acoustic panels for the walls for even more sound attenuation.
