Abstract
A demountable acoustical panel structure having a honeycomb core, and a thin, dense, sound transmitting glass fiber sheet of uniform thickness adhered to each of the oposed major surfaces of the core. One of the thin sheets advantageously carries segments or patches of a separable fastening means to enable the panel structure to be installed on a supporting surface provided with cooperating segments or patches of a separable fastening means by simply aligning said fastening means.

A demountable acoustical ceiling and wall panel structure, consisting essentially of:
- a lightweight core member in the form of a honeycomb having wall portions defining a plurality of open-ended cells and opposed cell end planes;
- a single-ply, thin, dense, sound transmitting, substantially homogeneous, glass fiber sheet of substantially uniform thickness secured to each of the opposed major surfaces of the core member in substantially parallel relation to each other and to said cell end planes;
- separable fastening means secured in preselected spaced relation on the exposed surface of one of said single-ply glass fiber sheets to enable the panel structure to be demountably secured on a supporting surface provided with cooperating separable fastening means with only hand pressure;
- and decorative coating on the exposed surface of the other of said single-ply glass fiber sheets, said panel structure having a flame spread of less than 25.
An acoustical wall panel installation, comprising:
- a panel supporting surface having separable fastening means secured in preselected spaced relation thereon;
- and a plurality of hand demountable acoustical panels positioned in abutting relation on said surface, said panels each being provided with a lightweight core member in the form of a honeycomb having wall portions defining a plurality of open-ended cells and opposed cell end planes, the opposed major surfaces of the core member having a single-ply, thin, dense, sound transmitting substantially homogeneous, glass fiber sheet of substantially uniform thickness secured thereon in substantially parallel relation to each other and to said cell end planes, one of said glass fiber sheets having separable fastening means secured in preselected spaced relation thereon for engaging the separable fastening means on said panel supporting surface with only hand pressure, said separable fastening means on the panel supporting surface and said panels acting to maintain the panels in spaced relation to the panel supporting surface to provide a sound insulating space therebetween, said panel structure having a flame spread of less than 25.
A demountable acoustical ceiling and wall panel structure, consisting essentially of:
- a lightweight core member in the form of a paper honeycomb having wall portions defining a plurality of open-ended cells and opposed cell end planes, said core member having a thickness of about 1/4 to about 1 inch;
- a single-ply, thin, dense, sound transmitting, substantially homogeneous, glass fiber sheet of substantially uniform thickness adhered to each of the opposed major surfaces of the core member in substantially parallel relation to each other and to said cell end planes, each of said single-ply sheets having a thickness of about 0.010 to about 0.020 inch and a density of about 8 to about 12 lbs/ft..sup.3 throughout;
- separable fastening means secured on the exposed surface of one of said single-ply glass fiber sheets;
- and a decorative coating on the exposed surface of the other of said single-ply glass fiber sheets, said panel structure having a flame spread of less than 25.
