A thermally modulating roof system wherein a minority of climate space between an existing and new roof is occupied by a phase change material assembly. The system maintains an industry standard of no more than a distance of about 4 inches between the roofs while still incorporating a substantial capacity to modulate an otherwise rising temperature of a facility during the day. Unique methods of installing the system, utilizing it and circulating air through the system to enhance performance are detailed.

An underlayment that meets underlayment requirements and provides thermal insulation is disclosed. The underlayment includes a core material and an upper emittance layer having an exterior surface. An upper reinforcement layer is positioned between the upper emittance layer and the core material. A first encapsulation layer is positioned between the upper emittance layer and the upper reinforcement layer. A second encapsulation layer is positioned between the upper reinforcement layer and the core material. The underlayment includes a lower emittance layer having an exterior surface. A lower reinforcement layer is positioned between the lower emittance layer and the core material. A third encapsulation layer is positioned between the lower emittance layer and the lower reinforcement layer. A fourth encapsulation layer is positioned between the lower reinforcement layer and the core material.

There is provided a decorative sheet which has satisfactory heat-shielding properties and can exhibit a design which is excellent in the degree of darkness. The decorative sheet includes an infrared-reflective substrate, and a decorative layer disposed on the substrate and including a solid printing layer and a picture layer, wherein the solid printing layer contains an infrared-transparent or infrared-reflective pigment and a binder resin, the infrared-transparent or infrared-reflective pigment containing (A) at least three compounds selected from the pigment group consisting of a quinacridone, an isoindolinone, a nickel azo complex and a phthalocyanine, or (B) at least one compound selected from the pigment group consisting of a composite oxide containing manganese and at least one metal element other than manganese, an azomethine-azo compound and a perylene compound, and wherein the picture layer at least partly contains carbon black and a binder resin.

Disclosed are methods to produce composite materials, which contain customized mixes of nano- and/or micro-particles with tailored electromagnetic spectral properties. In some defense-related applications, the use of such materials enables an improved spectral match between different structures, such as vehicles or buildings with the surrounding environment at least in the VIS and NIR wavelength range. This can camouflage the structures, and reduce the detectability thereof by ground-, air- or space-based multi-spectral long-range imaging systems, including aircrafts, drones, and satellites, and thus, generally delay, complicate, or eliminate detection or classification of the camouflaged structures.

Embodiments of a system and a method for manufacturing a cementitious panel can be used to produce a cementitious panel having a multi-layer air/water barrier membrane assembly. The layers of the membrane can be built up via a series of applicator stations applying a fluid composition using roll coating, for example. Between applicator stations the applied layer of fluid composition can be subjected to drying conditions via infrared heating. To help protect from the deleterious effects of infrared heating, the cementitious panel can be conveyed through a cooling tunnel after each drying section.

A thermally insulating sheet for installation adjacent a surface of an object comprising a reflective metalized polymeric insulation material having moisture vapour transference properties. An apparatus and methods for producing a reflective metalized polymeric thermally insulating assembly having moisture vapour transference properties are also provided. The insulation material provides enhanced thermal retention.

A radiant barrier sheathing product formed by directly bonding an unbacked, metallized polyethylene (PET) sheet or film, or similar sheet or film, directly to a wood or cellulosic structural panel. A very thin layer of aluminum (or similar metal) is deposited via vapor deposition manufacturing processes onto one or more sides of a polyethylene sheet to form a metallized PET sheet. The elimination of the backing substrate eliminates the cost and conversion expense of producing a combined overlay product.

A composite insulation batt is provided. The composite insulation batt includes a fiberglass insulation core within a sheath of closed cell plastic material and provides greatly increased insulating properties over conventional fiberglass insulation batts.

Insulated wall and roof sheathing systems for use in building construction designed to provide moisture permeable wall panels that protect from bulk water, excess air, and thermal transfer.

An insulating element for thermally insulating spaces, including closed cells, in which a first and a second group of closed cells are formed by first or second recesses in a first or second flat element and the first and the second flat elements form first or second connection regions between recesses adjacent to the edges of the openings, to which respectively a flat covering element closing the openings of a plurality of first recesses is bonded on a front side of the flat element. The second recesses are arranged between the first recesses on a rear side of the first flat element and the first recesses are arranged between the second recesses on a rear side of the second flat element such that the space remaining of the first and second recesses between the first and the second flat elements amounts to less than 50% of the space enclosed by the first and second recesses.
