Described herein is a stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.

Humidity and sag resistant building panel

Described herein is an acoustic building panel comprising a body comprising inorganic fiber in an amount ranging from about 60.0 wt. % to about 90.0 wt. % based on the total weight of the body; and microfibrillated fiber in an amount ranging from about 0.5 wt. % to about 10 wt. % based on the total weight of the body.

Sag-resistant acoustic board

Described herein is an stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.

Lamellar-structured highly microporous silicate compositions are provided which can be used as insulative articles and insulation material. The silicate is in the form of lamellae selected from the group consisting of mica and vermiculite. The silicate lamellae form the microporous structure, by forming the pore walls with the lamellae. Processes are described which prepare these compositions by removing the water from flocculated or unflocculated aqueous dispersions of chemically delaminated silicates while the arrangement of the lamellae in the dispersion is largely preserved, resulting in the highly microporous lamellar structure.
