A method of making a structural lightweight and thermal insulating concrete is described. The concrete has a coarse aggregate partly replaced by recycled plastic pieces. This enables the concrete to maintain a high compressive strength, low thermal conductivity, and low weight, while providing a use for waste plastic. The waste plastic pieces may comprise polyethylene in the form of flakes, fibers, or granules. Due to its low unit weight, adequate compressive strength and high thermal resistance the developed concrete can be used as a structural lightweight and thermal insulating concrete. The use of this concrete leads to economic and environmental benefits.

A composite wall panel having a front surface, a rear surface, and side surfaces extending therebetween is provided. The panel includes a cured composition of pieces of cellulose and/or chaff and at least one binder. A wall assembly is also provided. The assembly includes: a frame including a plurality of linearly arranged elongated studs having a top end, a bottom end, and a first longitudinal side and a second longitudinal side extending between the respective ends; a plurality of interconnected wall panels mounted to the first side of the elongated studs of the frame to form a first wall portion; a plurality of interconnected panels mounted to the second side of the elongated studs to form a second wall portion; and an insulating layer inserted within a cavity between the first wall portion and the second wall portion.

The biodegradable composite insulation material is a composite of wood from the date palm tree (Phoenix dactylifera) and polylactic acid. The composite may have up to 50 wt % date palm wood powder of maximum particle size of 212 m, the balance being polylactic acid (PLA). The composite may be prepared by melt blending the date palm wood powder with polylactic acid pellets in a twin screw extruder at 190 C., followed by compression molding the blend in a press or the like into the desired shape for building thermal insulation, and finally, annealing the molded product for three hours at 95 C. The composite material is biodegradable, thermally insulating, water-resistant and relatively strong.

Process for manufacturing a blow-in insulation material made of straw, including a processing step in which the straw is crushed between rolls in a crushing apparatus, a crushing nip in the crushing apparatus being selected in such a way that the straw nodes are crushed during the crushing operation.

Disclosed are biodegradable insulation materials comprising a structural scaffold; and at least one temperature resilient fungus. Also disclosed are methods of making and using biodegradable insulation materials comprising a structural scaffold; and at least one temperature resilient fungus. For example, disclosed are methods of insulating an infrastructure comprising administering the disclosed biodegradable insulation materials to an infrastructure.

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.

An insulation system for hanging insulation in a truss is disclosed and includes a first rail configured to be installed on a first truss and a second rail configured to be installed on a second truss spaced apart from the first truss. A first cavity is established between the first rail and the second rail. Further, the first cavity is configured to receive and engage a first insulation batt.
