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.
