BCM’s TECHLITE® Pipe Insulation is a fast, efficient way to insulate a variety of industrial and critical process foam insulation applications. In other words, a 50w attenuator will sound the same as a 200w attenuator on smaller amps. We are musicians ourselves and share your passion for making it. Tecnalco's product range has grown to the now 17 chapters its catalogue makes up, including products such as: volume control dampers, sound attenuators, fire dampers, jet diffusers, air louvers, exhaust valves and perforated diffusers.
