Sinusoidal shaped member units and support member units are parts that form pre-stressed assemblies having flexural properties. Sinusoidal shaped members are relaxed material members that have been elastically deformed. Support members maintain the elastically deformed state of the sinusoidal shaped members. The sinusoidal shaped members and support members are organized into pre-stressed curvilinear assemblies containing stored elastic potential energy that is equal to the work done by the forces that deformed their pre-stressed structure. The assemblies' sinusoidal shaped members and support members are adapted to use materials having exceptional mechanical properties and flexural strength. This includes nano-composites. The assemblies' pre-stressed state enhances its mechanical, electrical and structural performance. The size, number, density and possible geometric configurations of the sinusoidal shaped member units and support member units within an assembly/structure is vast. Products of this sinusoidal building system have mechanical and structural applications and can be manufactured using an automated process.

A non-asphaltic breathable sheet is provided that includes at least one breathable polymer layer and at least one nonwoven layer. The breathable sheet may include an open-mesh reinforcing fabric embedded in a breathable polymer layer. The breathable sheet has an advantageous balance of strength, water resistance, and permeability to water vapor.

A method and apparatus for making a water drainage-promoting wrap for applications such as housewrap and roofing underlayment. A substrate, which may be breathable or non-breathable, is conveyed through a nip between a rotating sleeve and a roll, the sleeve having a plurality of apertures therein. A fluid resin composition is fed into the sleeve and is fed out through the apertures in the sleeve as it rotates and as the substrate moves through the nip, forming spaced-apart spacer elements on a face of the substrate. The spacer elements are then dried or cured.

The present invention provides a structure protection sheet capable of dramatically reducing a construction period to place protective layers on surfaces of structures such as concrete, protecting the structures for a long time, preventing swelling phenomena caused by water vapor inside the concrete, and preventing a decrease in attachability. The present invention relates to a structure protection sheet including: a polymer cement cured layer on a side facing a structure; and a resin layer on the polymer cement cured layer, the structure protection sheet having a water vapor transmission rate of 10 to 50 g/m.sup.2.Math.day.

In one aspect, a fastener includes an elongated fastener body with an external surface extending between the first end and the second end, and a coating material disposed on at least a portion the external surface. In another aspect, a fastener includes an elongated fastener body with an external surface extending between the first end and the second end, and a polymer annulus surrounding at least a portion of the external surface of the of the elongated fastener body at or adjacent the head of the fastener.

An adhesive membrane is provided which is airproof and moisture-proof and permeable to water vapor, intended for surfaces of buildings, including at least one film (1) permeable to water vapor and a layer of a pressure-sensitive adhesive, the adhesive layer being deposited on one of the faces, a so-called lower face of the film; the membrane includes a first layer (2) of a pressure-sensitive adhesive deposited on the totality of the lower face of the film over a thickness of less than or equal to 50 μm and a second layer (3) of a pressure-sensitive adhesive deposited on the first layer (2) for covering the first layer (2) over 2 to 99% of the surface of the first layer (2) over a thickness comprised between 50 μm and 2 mm.

A passive thermal management system and methods of using a thermoresponsive hydrogel coating configured to autonomously switch between a heating state and a cooling state based on ambient temperature. At temperature greater than a lower critical solution temperature of the thermoresponsive hydrogel, the thermoresponsive hydrogel coating becomes solar reflective and has enhanced radiative cooling ability to achieve daytime radiative cooling. At temperatures less than the lower critical solution temperature, the thermoresponsive hydrogel coating becomes transparent to facilitate absorption of solar radiation by sun absorber.

A flooring material having a textile pad substructure with a density of greater than 10 pounds per cubic foot is provided. The textile pad has reinforcement and binding fibers. The binding fibers are thermoplastic and are used to bind the reinforcement fibers together. The pad is created by heating and compressing a fibrous textile batt so that it has a density of greater than 13 pounds per cubic foot.
