Johns Manville Whispertone Wallboard is a widely used raw acoustical fiberglass board due to its excellent thermal and acoustical properties. Manufactured from fine, rotary-process, boorsilicate glass fibers bonded with a special thermosetting resin, Whispertone produces a structurally rigid board-type insulation.

The top surface is smooth and uniform in color. The high tensile fibers resist settling, breakdown or sagging from vibration. The countless air spaces in Whispertone Wallboard create effective sound absorption as well as thermal properties. Perceived noise from air movement and mechanical equipment is noticeably reduced.

This product is a raw material that is commonly covered with acoustical fabric for non-industrial interior applications.
