New Grout Free STC Retrofit System


Security Metal Products has created an innovative acoustical split frame that does not require grouting to achieve high sound ratings up to STC 51 (operable). The SMP Retrofit System is the perfect choice for any room where sound transmission needs to be kept to a minimum. The STC Retrofit System is also lead free and will help to insure the quality of sound in or outside the room won’t be affected by other noise sources.

The SMP Grout Free STC Retrofit System includes metal sound door, frame, seals, threshold, door
bottom and cam-lift hinges.
