A method of producing a fire retarded cellulose fiber material composed of both a liquid fire retardant and a powdered fire retardant useful in producing insulation and other such products is provided.

The disclosure provides a method of forming an acoustical panel base mat, including providing a green board including an alkyl ether sulfate surfactant, wherein the green board includes from about 10 to about 40 wt. % solids, and dewatering the green board slurry to form a dewatered green board, wherein the dewatering comprises supplying hot air and applying a vacuum to the green board.

A structural assembly (20) providing both a surface (21) and an insulating stratum associated with the surface. The assembly (20) can comprise structural members (23-24) and pods (30) associated with the structural members (23-24). The pods (30) contribute to structural integrity, thermal insulation, and/or sound attenuation. The pods or pod-like material can be used in or on horizontal or vertical cavities, in or on horizontal or vertical surfaces, and/or incorporated into a structural assembly or equipment housing.

Environmentally responsible insulating construction blocks and structures constructed primarily of recycled materials are disclosed. The environmentally friendly construction blocks and structures comprise shredded rubber tire pieces coated with silica fume, slag cement and cement, which are then mixed with water and formed in a mold. A layer of grout or a fireproof material may be disposed on one side of the environmentally responsible insulating construction block. The environmentally responsible insulating construction blocks provide high insulation as well as strength for applications such as green roofing, wall construction and green roofing decks. Environmentally friendly structures can be built by pouring the coated shredded rubber tire pieces into molds to form walls, and then to pour a layer of the coated shredded rubber tire pieces as a roof deck, thereby creating a self-supporting structure in a monolithic pour.

The present invention relates to ash recycling and use in thermal insulation (decrease of thermal transmission from inside buildings into outside, and vice versa). Ash insulation panels are made of the following basic materials: ash and Polystyrene (PS) and/or waste plastics made of Polystyrene and chemical bond. These panels have many advantages beside thermal insulation such as lightweight and low water absorption rate. They are produced by mixing the mentioned basic materials, casting the mixture into molds of variable size and shape depending on the desired product, pressing the mold, and treating the final product thermally.

A cellulose-based fire resistant insulation and related method for making the same. The insulation includes a plurality of superstructures that establish voids in the insulation. The insulation may be blown in place while the superstructures maintain the void portion of the insulation. The insulation is made with fiber residuals, either alone or in combination with other cellulosic materials. The method of making the insulation includes the steps of treating the cellulosic materials with a fire retardancy chemical or chemicals and creating bonds between the fibers to form the superstructures.

The water resistive barrier system may include a foam panel coupled to a frame of a building. The system may include a membrane above the foam panel. The system may include a scratch layer above the membrane. The system may include an exterior layer above the scratch layer. The system wherein the foam panel has a thickness between two and eight inches may have a structural tensile strength of 50 psi. In some embodiments, a method of manufacturing the water resistive barrier system may include providing a foam panel. The method may include coupling a membrane above the foam panel. The foam panel and the membrane can be manufactured as one panel. The method may include providing a scratch layer material for further coupling above the membrane during an installation. The method may include providing an exterior layer material for further coupling above a scratch layer during the installation.

The building insulation system includes a reflective, non-porous bag filled with thermal insulation material. The covering of the bag is made from reflective polymeric facer or plastic, which facilitates reflection of thermal energy radiation. The reflective non-porous bag provides a thermal barrier for conduction, convection and radiation aspects of thermal energy transfer.
