In critical listening and interior noise-sensitive spaces where proper sound management is of critical importance, TECHLITE® continues to be at the forefront of acoustics innovation. All of our products provide both superior sound absorption as well as a decorative solution to noise control for any type of interior space.

We’d like to believe we are quite creative here at TECHLITE®, which indeed translates to acoustical and architectural solutions that satisfy both form and function. TECHLITE® 3-Point Wedge Panels are designed to mitigate acoustical problems in large cubic volume spaces such as auditoriums, theaters, gymnasiums, industrial buildings to help comply with OHSA regulations and any large venue where there is reinforced sound such as sports arenas. The wedges are designed at 6″ thick and their acoustical performance in the low frequencies is second to none, boasting a Noise Reduction Coefficient (NRC) 1.25 and are 58% absorptive at 125 Hertz in accordance with ASTM C 423-17 Standard Method for Sound Absorption and Sound Absorption Coefficients by the Reverberation Room Method.

The 3-Point Wedge Panels can be direct-applied to ceilings, can be laid in pre-engineered suspension systems and adhered to walls, the latter being their most common application. They can be arranged to create various architectural patterns and effects, and they integrate exceptionally well with interior building mechanical, electrical and plumbing systems.
