The invention includes a microbe-mitigating architectural barrier that includes a barrier forming material, and at least one biocide. The barrier forming material may be a bitumen product, an elastomeric polymer and combinations thereof. The microbe-mitigating architectural barrier may be formed by applying an emulsion composition directly to an architectural surface, or may be pre-formed and adhered or otherwise secured to the architectural surface in the form of a sheet or film. The invention also includes architectural assemblies and/or building envelopes that include the microbe-mitigating barrier. Related methods encompassed within the invention include a method of preparing an architectural barrier that includes: (a) preparing an emulsion that comprises a barrier forming material chosen from a bitumen product, an elastomeric polymer and combinations thereof, and at least one biocide, (b) applying the emulsion to at least one architectural surface, and (c) drying and/and or curing the emulsion to form a barrier.

A panel suitable for constructing a floor or wall covering includes a core comprising a mineral composite comprising a mineral and a filler. The panel further comprises an additive within the core in order to improve the flexibility and/or tensile strength of the panel.

Provided is a decorative sheet comprising a base material layer, a transparent resin layer and a surface protection layer in the presented order, wherein at least one of the base material layer and the transparent resin layer is constituted by a resin composition comprising a resin having an ultraviolet absorption wavelength at least at 270 to 300 nm; absorbance All of the surface protection layer at wavelengths from 270 to 300 nm is 0.6 or more; and absorbance A.sub.12 of the transparent resin layer and the surface protection layer at wavelengths from 270 to 300 nm is 2.7 or more, and wherein the decorative sheet can suppress time-dependent degradation caused by ultraviolet ray, and has excellent weather resistance. Also provided is a decorative material obtained using the decorative sheet.

There are provided a decorative sheet which has excellent weatherability and in which white pigment particles are dispersed well, and a decorative material using the decorative sheet. The decorative sheet includes at least a substrate and a surface protective layer. The surface protective layer contains an ultraviolet absorber, and the substrate contains white pigment particles. The white pigment particles are titanium oxide particles having a coating containing Al element and Si element and formed on part or the whole of their surfaces, and contain Ti, Al and Si elements in the following mass ratio: when Ti is taken as 1, Al is not less than 0.02 and less than 0.20, and Si is more than 0.002 and not more than 0.070.

Provided is a decorative sheet comprising a base material layer, a transparent resin layer and a surface protection layer in the presented order, wherein at least one of the base material layer and the transparent resin layer is constituted by a resin composition comprising a resin having an ultraviolet absorption wavelength at least at 270 to 300 nm; absorbance All of the surface protection layer at wavelengths from 270 to 300 nm is 0.6 or more; and absorbance A.sub.12 of the transparent resin layer and the surface protection layer at wavelengths from 270 to 300 nm is 2.7 or more, and wherein the decorative sheet can suppress time-dependent degradation caused by ultraviolet ray, and has excellent weather resistance. Also provided is a decorative material obtained using the decorative sheet.

Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.

A wood or engineered wood structural panel, such as, but not limited to, OSB (“oriented strand board”) or plywood, that is both fire-resistant and water resistant. The panel is factory-coated with a product that provides fire resistance. The treatment gives it a Fire-Resistant (FR) performance (for use in a one- or two-hour rated assembly). The panel also is overlaid or coated in a factory setting with a weather/water resistive barrier (WRB). The structural panel thus combines a fire-resistant structural sheathing and WRB product in one integrated panel produced at a factory prior for installation at a job site.

The present disclosure relates to a plaster board comprising a first layer of hardened plaster material comprising a first surface and an opposed second surface, a second layer of hardened plaster material comprising a first surface and an opposed second surface, wherein the first surface of the second layer faces the first surface of the first layer, and a viscoelastic interlayer disposed between the first surface of the first layer and the first surface of the second layer, wherein the interlayer includes a score-and-snap element.

The present invention provides a decorative sheet having excellent work characteristics, weather resistance, and scratch resistance and a decorative material using the same. Disclosed are a decorative sheet including a base material and a surface-protecting layer, wherein at least one of the base material and the surface-protecting layer contains a white pigment, the surface-protecting layer is a cured product of a curable resin composition, and a Martens hardness of the decorative sheet is 9 N/mm.sup.2 or more and 25 N/mm.sup.2 or less; and a decorative material using the same.

Provided is a panel for constructing a floor or wall covering. The panel includes a core which includes a mineral material and at least one dendritic additive for improving the flexibility and tensile strength of the panel. The panel further includes at least one pair of opposite side edges. The pair of opposite side edges are provided with interconnecting coupling means for interconnecting adjacent panels.
