  • Patent number: 10697174
    Abstract: A retrofitting appliqué for stepped application to a building wall construction. For external retrofitting, the system has an air barrier layer impermeable or semi-permeable for moisture, a ventilated air cavity used to modify temperature and/or remove water that may be coming from both sides or to modify the relative humidity of the ventilation air, a layer of thermal insulation, a composite material called Eco-Wrap with capillary active capability, in which a hydronic heating or cooling system may be located, and a surface finishing layer. For internal retrofitting, the system has an air barrier system arranged onto the wall of the building and separated from a layer of permeable or semi-permeable thermal insulation by a ventilated air gap. The layer of insulation, in turn, is in contact with a layer of Eco-Wrap. A permeable interior finishing layer that may also have capillary active performance is in contact with the Eco-Wrap. Methods for installing the retrofitting appliqué are also disclosed.

  • Patent number: 10011990
    Abstract: A laminated board is secured to the inner wall of a cavity wall construction to establish a defined spacing between the inner and outer walls and prevent excess mortar from bridging to the inner wall. The laminated board has a series of spaced sockets into which fasteners may project into the face of the inner wall or framing thereof to secure the outer wall. The board is installed prior to the construction of the outer wall and establishes a minimum spacing or gap between the walls based upon the thickness of the board. The outer wall is constructed immediately adjacent to the outer face of the laminated board. The board is impervious and eliminates bridging by the mortar, eliminates transfer of bulk water from the exterior finish to the inner wall and provides an air conduit to exhaust even the minimal amounts of vapor that will occur in the cavity.

  • Patent number: 9771714
    Abstract: A manufactured apparatus formed via a deep drawn stamping process for use within a building as an insulation device applied both to the exterior sheathing of an existing or new edifice and also above the ceiling plane below its roof structure; which consists of two half vessels made from malleable material, each containing similar structural appurtenances on their exterior faces, which when bonded together encase a cruciform rigid plastic grid-like lattice having many apertures therein for the complete removal of air within this subsequently sealed vessel. This complete state of vacuum totally prevents or drastically stops the transmigration of heat energy loss via conduction and convection from the interior of a building's space to the outside environment during the winter months; and vice versa, thus also retarding any interior gain of ambient heat during the hot summer months.

  • Patent number: 8424251
    Abstract: Panels for use in building construction (partitions, walls, ceilings, floors or doors) which exhibit improved acoustical sound proofing in multiple specific frequency ranges and also present improved structural integrity, are provided. The improved performance is achieved through the use of one or more layers of glue such that at least one layer of glue includes a viscoelastic material in a first pattern and a structural adhesive in a second, non-overlapping pattern. The viscoelastic material may have a varied shear moduli and functions as a glue and energy dissipating layer. In some embodiments, one or more constraining layers separating one layer of glue may be included. The constraining layer may be formed of a material such as gypsum, cement, metal, cellulose, wood, or petroleum-based products such as vinyl, plastic, or rubber. In some embodiments, standard wallboard, typically gypsum, comprises the external surfaces of the laminated panel.

  • Patent number: 8418807
    Abstract: A noise abatement wall includes a frame defining a window, at least one shell, at least one sheet of sound-insulating material and a sheet of screen material. The at least one shell has a base panel portion and a peripheral panel portion integrally formed with and extending perpendicularly from the base panel portion to surround the base panel portion thereby forming a shell cavity. The at least one shell is sized and configured to be received by the window in a close-fitting relationship therewith and is connected to the frame. The at least one sheet of sound-insulating material is disposed in and occupies the shell cavity. The sheet of screen material covers the at least one sheet of sound-insulating material and is connected to the frame. A plurality of noise abatement walls are connected together to form a noise abatement wall system for abating noise generated from stationary noise-generating equipment.

    Abstract: An apparatus and method for constructing pre-insulated structural panels is disclosed that has a tongue and groove assembly arrangement. Each panel may include one or more c-channels or profiles embedded in expandable polystyrene (EPS) foam to provide structural integrity to the panels, and resulting wall. The panels may be covered with siding, stucco, or similar materials. A chase may be formed horizontally in the panels to provide a wiring conduit through the panel. The panel may also provide when assembled, a vertical chase formed between the mated panels along the length of the panel for wiring. Acoustical properties may be formed in the surface of the EPS portions to provided added acoustical damping measures.

  • Patent number: 8371084
    Abstract: An acoustic ceiling panel for a lay-in or suspended ceiling includes a core portion, and front and rear layers covering front and rear sides, respectively, of the core portion. The air flow resistance of the core portion does not exceed about 100 MKS rayls. The air flow resistance of the front layer lies in the range of about 300 to about 800 MKS rayls. The air flow resistance of the rear layer lies in the range of about 300 to about 1200 MKS rayls. The panel would be supported on a grid suspended below a structural ceiling to form an air space therebetween.

  • Publication number: 20130031852
    Abstract: An attenuating element includes a head part, neck part and base part. The neck part is narrower compared to the head part and neck parts of adjacent attenuating elements form a continuous channel. Via the head parts, this channel is connected so that the cross-sectional area of the head parts is smaller than the cross-sectional area of the base parts. In this way, a water-control structure, sound-attenuating wall and the like can be provided. Such attenuating elements can be produced in a very simple manner by dividing them vertically and producing each of the vertical parts from concrete in a mould.
