Perforation Guide

Carritec has created actual size perforation patterns to be used as a guide for aesthetic selection and performance criteria.

Noise reduction may be achieved by adding acoustical absorbing material. Your acoustical consultant may make specific recommendations. Contact Carritec for available options.
