Abstract
An acoustically absorbent porous panel with a layer constructed from a substantially continuous open-celled porous material comprising a cured foamed cementitious material including a first face and a second face. The first face has a surface with a substantially planar profile and the second face has a substantially geometric pattern of depressions formed therein comprising approximately 50% to approximately 90% of the layer by volume.
Claims22
An acoustically absorbent porous panel comprising:
- a layer constructed from a substantially continuous open-celled porous material comprising a cured foamed cementitious material having a first face and a second face;
- the first face having a surface with a substantially planar profile;
- and
- the second face having a substantially geometric pattern of depressions formed therein comprising 81% to approximately 90% of the layer by volume,
- wherein the foamed cementitious material is formed from an aerated aqueous foam slurry comprised of:
- about 29% to about 74% by weight of cement;
- about 17% to about 60% by weight of water;
- about 0.05% to about 15% by weight of synthetic organic fibers;
- and
- about 0.01% to about 10% by weight of surfactant.
An acoustically absorbent porous panel comprising:
- a layer constructed from a substantially continuous open-celled porous material comprising a cured foamed cementitious material having a first face and a second face, the first face having a surface with a substantially planar profile and the second face having a substantially geometric pattern of depressions formed therein comprising 81% to approximately 90% of the layer by volume;
- and
- a scrim material attached to the second face, wherein the scrim is formed from a non-woven fiberglass material having an air flow of approximately 100 cubic feet per minute to approximately 1000 cubic feet per minute.
