An insulation product may include a container, a first insulation material forming a first layer inside the container, and a second insulation material forming a second layer inside the container, and the first layer is compressed by the second layer. A structure in a building may include studs, first and second claddings mounted to opposite sides of the studs, and structure spaces defined between the studs and the opposing claddings. A first insulation material may include first layers on and substantially covering a first one of the claddings inside the structure spaces. In addition, a second insulation material may have second layers inside the structure spaces. The first layers are compressed and substantially covered by the second layers, and the second layers substantially cover a second one of the claddings inside the structure spaces.

An environmentally friendly, bio-based binder system that is useful for the formation of fiberglass insulation, the system includes: A) an aqueous curable binder composition, which includes a carbohydrate and a crosslinking agent; and B) a dedust composition, which includes a blown, stripped plant-based oil and optionally at least one emulsifying agent. The bio-based binder system is typically heated to form a cured binder system.

A fibrous insulation product having a plurality of randomly oriented glass fibers and a binder composition that holds the glass fibers together is disclosed. The fibrous insulation product has an R-value in the range of 10 to 54 and, after curing, has a density, when uncompressed, in the range of 0.30 pcf to 2.7 pcf. Furthermore, the fibrous insulation product includes glass fibers that, prior to the application of the binder composition, have an average fiber diameter in the range of 15 HT to 19 HT and a quantity of binder that is in the range of 2% to 10% by weight of the fibrous insulation product. The fibrous insulation product also has an average fiber diameter to density ratio (Fd/D) of less than or equal to 40 and a comfort factor less than or equal to 3.417(Fd/D)+60.

A demountable structure system is disclosed. The demountable structure system may have a roof system positioned atop one or more structural panel(s) and a floor system positioned beneath one or more structural panels(s). The structural panels may have different shapes, configurations, and features, and may support the roof system in order to form a demountable structure. Alternatively, the roof system is omitted and a wall or other structure can be formed from the structural panels. Each structural panel may have other features, such as finish panels, fabric panels, accessory mounts, recessed lighting, electrical outlets, etc. Some structural panels have sound dampening features, such as to form portable musician's sound booth. Thus, a structure may be formed which is both readily disassembled, yet also sturdy.

An environmentally friendly, bio-based binder system that is useful for the formation of fiberglass insulation, the system includes: A) an aqueous curable binder composition, which includes a carbohydrate and a crosslinking agent; and B) a dedust composition, which includes a blown, stripped plant-based oil and optionally at least one emulsifying agent. The bio-based binder system is typically heated to form a cured binder system.

An insulation product may include an insulation material. The insulation material may include at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation. The insulation material may include a first end and a second end positioned opposite the first end. The first end may include a protrusion. At least a portion of the protrusion may widen in a direction opposite the second end. The second end may define a cutout that substantially matches a size and shape of the protrusion. The cutout and the protrusion may be aligned with one another along a length of the insulation material.

A method of manufacturing a mineral fibre thermal insulation product comprises the sequential steps of: Forming mineral fibres from a molten mineral mixture; Spraying a substantially formaldehyde free binder solution on to the mineral fibres, the binder solution comprising: a reducing sugar, an acid precursor derivable from an inorganic salt and a source of nitrogen; Collecting the mineral fibres to which the binder solution has been applied to form a batt of mineral fibres; and Curing the batt comprising the mineral fibres and the binder which is in contact with the mineral fibres by passing the batt through a curing oven so as to provide a batt of mineral fibres held together by a substantially water insoluble cured binder.

An un-reacted substantially formaldehyde free curable binder solution for binding loose matter consists essentially of a solution obtainable by dissolving a reducing sugar, an ammonium salt acid precursor, optionally a carboxylic acid or a precursor thereof and optionally ammonia in water.

Insulation devices, methods and related construction techniques are provided. An exemplary device may include a body having a plurality of openings defining an openwork, to allow the passage of air therethrough when placed in contact with insulation material. The device may further include a plurality of spacer struts and/or spacing depressions fixedly attached to the body. The struts may be configured to maintain a predetermined distance between a first side of the insulation material and a building surface. The body and struts act together to define and maintain a space between the first side of the insulation material and the building surface, for example, for ventilation. The building surface can be the bottom face of a roof, an insulated attic floor, wall sheathing or a soundproofed demising wall, for example. The spacer device can be capable of being transported and stored together with, or as a separate item from, the insulation material, and can also be stored in nested layers. The device can also be stored in rolled form. The openwork of the device can additionally or alternatively include a sheet of entangled net filaments or other similar material.

A temperature modulating blanket utilizing a reflective surface to block radiation away from a phase change material during daylight and in thermal conductivity with the material to allow heat conduction out of the material at night at a faster rate than it is absorbed during the daylight. The reflective surface is uniquely tailored to both serve a reflective function during daylight while also being sufficiently thermally conductive to facilitate the heat conduction as indicated during night. Additionally, the facilities may be uniquely configured to promote an attic circulation that further facilitates freezing and recharge of the phase change material of the blanket during night hours.
