An insulation system and method comprising an insulation layer, an atmospheric regulation layer, a structural support, and an external surface; wherein the atmospheric regulation layer is supported by the structural support, wherein the insulation layer is located between the atmospheric regulation layer and the external surface, wherein the atmospheric regulation layer has a water vapor permeability of not greater than 3 perms at a relative humidity of 25% as measured by ASTM E96 Procedure A Dry Cup, and a water vapor permeability of at least 6 perms at a relative humidity of 75% as measured by ASTM E96 Procedure B Wet Cup, wherein the atmospheric regulation layer has a fire class A rating as measured by ASTM E84, and wherein the continuous atmospheric regulation layer has a ACH50 value of not greater than 10, wherein ACH50 represents an air exchange at 50 Pascals.

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 stone panel (1) is provided. The composite stone panel (1) comprises a front panel and a backing panel. The back of the front panel comprises a counter-relief image (11) filled with a light-transmitting reinforcing filler and is attached to the backing panel. The backing panel comprises a light source (6) or an opening for receiving the light source (6). The light source (6) or opening is positioned to transmit light towards the counter-relief image (11). A relief (3) is then formed at the front of the composite stone panel (1). The relief (3) is positioned opposite to the counter-relief image (11).

Process for fire resistant protection of the technical elements of a building by means of one or more prefabricated isolation blocks, enabling pre-isolation of a vacant space in the structure of a building. The block comprises an easily modelled fire resistant material and is disposed before pouring the concrete of the structure of the building. The prefabricated block is then opened up in such a manner as to install the technical elements having to be protected from fire.

A system and method for a fire-retardant insulation product are provided, along with a fire-retardant chemical formulation. An insulation product provided includes cellulose fibers and a fire-retardant chemical formulation. The fire-retardant includes calcium chloride.

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.

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.

A retrofitting appliqu for stepped application to a building wall construction. For external retrofitting, the system has an air barrier layer impermeable or semi-permeable for moisture, a ventilated air cavity used to modify temperature and/or remove water that may be coming from both sides or to modify the relative humidity of the ventilation air, a layer of thermal insulation, a composite material called Eco-Wrap with capillary active capability, in which a hydronic heating or cooling system may be located, and a surface finishing layer. For internal retrofitting, the system has an air barrier system arranged onto the wall of the building and separated from a layer of permeable or semi-permeable thermal insulation by a ventilated air gap. The layer of insulation, in turn, is in contact with a layer of Eco-Wrap. A permeable interior finishing layer that may also have capillary active performance is in contact with the Eco-Wrap. Methods for installing the retrofitting appliqu are also disclosed.

A building component utilizing a pourable polyurethane or structural foam that can be used for floors, walls, and roof assemblies with a frame with an interior, back or a front, multiple partition beams forming cells in said frame, pourable polyurethane or structural foam exterior backing attached to said frame back. The structural foam is poured into said cells to a desired level, and after said structural foam is poured into said cells, said interior backing is attached to said frame front. Cabling is used to improve movability of the invention, and improve on wind loading and seismic requirements of the present invention. Safety is also improved during the manufacturing process, loading, unloading, and in final assembly through the use of cabling.
