Abstract: Disclosed is waterproofing sheeting that uses a polyester layer that provides high lateral stability and puncture resistance. The waterproof sheeting can be used in many applications including waterproof roof underlayments, waterproof sheeting for foundations, underlayment for tile and flooring and various other applications. The waterproof sheeting can be manufactured without many of the problems associated with the granular coatings of existing waterproof sheeting that create excessive wear and environmental hazards.

Abstract: A material for use in building construction (partition, wall, ceiling, floor or door) that exhibits improved acoustical sound proofing and fracture characteristics optimized for efficient installation. The material comprises a laminated structure having as an integral part thereof one or more layers of viscoelastic material which also functions both as a glue and as an energy dissipating layer; and one or more constraining layers, such as gypsum or cement-based panel products modified for easy fracture. In one embodiment, standard paper-faced wallboard, typically gypsum, comprises the external surfaces of the laminated structure with the inner surface of said wallboard being bare with no paper or other material being placed thereon.

Abstract: Laminated structures for use in building construction are fabricated by a manufacturing process such that the laminating steps to not require elevated drying temperatures or an extended dwell time at any point. The process employs stock materials that simultaneously reduce cost and improve performance. This is accomplished using a specially formulated viscoelastic glue and ambient temperature drying apparatus. As a result, the production capacity of the manufacturing facility, cost of goods, and delivered performance are greatly improved over existing methods.

Abstract: The present invention provides an improved uncoupling membrane for use between a top coat of mortar in which a tile layer is set and a base coat of mortar applied to a substrate surface. The membrane being of the type including a dimpled plastic layer, the dimples defining, on one side of the membrane, a number of depressions into which the top coat extends in use and, on the other side of the membrane, a number of protuberances. The improvement may include a polymeric coating overlaying the plastic layer and to which the top coat of mortar adheres in use.

Abstract: A single layer roofing material having a headlap portion and a tab portion wherein the headlap portion has a color-value gradient or gradation and the tab portion has tabs and openings. The tabs may have a relatively uniform color. Openings between tabs expose the color gradient of the headlap portion when a first sheet of the roofing material is installed over a second sheet on a structure. A plurality of horizontal striations may be used to establish the desired color-value gradient. An illusion of depth or thickness is created when the roofing material is applied to a structure, such as a roof deck. The amount of tone and contrast may be selected to create the desired illusion of depth or thickness. The amount of contrast may be varied depending upon the color selected for each roofing material. The number of horizontal striations and their width may also be varied to provide the desired color-value gradient. Tab color, shape and size may also be varied to enhance the illusion of depth.
