A method is provided for forming an adhered membrane roof system that meets Factory Mutual (FM) 4470/4474 standards for wind uplift. The method comprises applying a bond adhesive to a substrate on a roof to form an adhesive layer and applying a membrane directly to the adhesive layer. The bond adhesive includes a moisture-curable polymer.

A batten for use in roofing applications is defined by an upside-down U-shaped channel with outwardly projecting horizontal flanges. In certain versions, the legs forming the sides of the channel are asymmetrical to allow vertical orientation of at least one of the legs when installed on an angled roof. This improves strength and load bearing of the installed member, and allows it to provide a fall barrier for roof installers. In certain versions, one of the flanges has a ribbed impact reduction zone. This zone deforms when a building anchor, such as a nail, passes through it to anchor the member to a roof. The deformation prevents anchors fired from conventional equipment from passing completely through the member and holds the anchors more securely in place.

This disclosure relates to an article that includes a nonwoven substrate, a first film supported by the nonwoven substrate, and a second film such that the first film is between the nonwoven substrate and the second film. The first film includes a first polymer and a pore-forming filler. The difference between a surface energy of the first film and a surface energy of the nonwoven substrate is at most about 10 mN/m. The second film includes a second polymer capable of absorbing and desorbing moisture and providing a barrier to aqueous fluids.

The present invention relates to a water resistant, UV resistant, vapor permeable, air barrier roofing underlayment assembly for use on sloped roofs comprising a substrate of permeable polyester, a permeable copolymer acrylate coating bonded to the permeable polyester substrate and a pressure sensitive permeable copolymer adhesive secured to the permeable acrylate coating.

A light steel roof truss with a structure of a double continuous beam includes structural beams (1) and structural columns (2). The structural beam (1) consists of a pair of continuous beams, and the structural column (2) is located between the two continuous beams through locating holes (4). Thereby the stability of a support structure of the roof truss is increased, and the supporting members of the roof truss can be connected conveniently.

A method for producing an asphaltic sheet, the method comprising of providing an asphaltic sheet; and applying expandable graphite particles to the asphaltic sheet.

The present disclosure describes a residential dwelling unit designed for vertical expansion by way of a removable and re-attachable roof system. By removing certain components of the original dwelling unit's roof, that same structure can be converted into the floor of a subsequent vertical addition. Specific components that were removed from the original roof are then re-attached on top of the vertical addition.

A covering of a damaged or uncompleted building; the covering including a film of heat shrinkable material stretched over damaged or uncompleted portions of the building; the film formed as a sheet comprising an assembly of lengths of the heat shrinkable material applied to surfaces of the building.

This invention provides fall protection systems, in metal building construction, and methods of installing such systems. A given such system comprises a suspension fabric, supported by a grid-work of longitudinal and lateral support bands. The distance of the safety band from the rafter corresponds to about 40 percent to about 75 percent of the diameter of the bag. Thus for a 30-inch diameter bag, the distance between the edge of the rafter and the middle of the safety band is about 12 inches to about 23 inches. The safety band protects the suspension fabric from being cut by the near edge of the rafter when a falling object impacts the fall protection system near the edge of the rafter.
