ACOUSTIC PROPERTIES

Exciting new developments are unfolding in this field and Bellcomb is committed to providing clients with reliable, tested acoustical control offerings.

First, it is important for us to know what you need in the area of acoustical control. Do you want sound deflected, reduced or absorbed? Frequency ranges and decibel levels influence material selection and specification for both cores and skins. Skins tend to influence higher frequencies; stiffer skins will encourage greater deflection. Cores tend to absorb lower frequencies. It is a matter of physics that the greater the mass of a material, the less easily sound is able to travel through it. Greater mass, however, is in direct competition to one primary advantage to Bellcomb composite structural panels: the need to be lightweight.

Most applications also have other performance characteristics to take into consideration, such as weight, fire resistance, thermal efficiency, even visual appearance. This is where Bellcomb offers you so much. You talk and we listen; we ask you questions and you describe your problem. We truly offer a customer engineered solution using structural composite lightweight panels.

Our professionals are ready to discreetly work through your specific panel application requirements to find the best possible panel solution. Call us at 763-537-0200 or e-mail us at sales@bellcomb.com and see how Bellcomb can help you.
