A clip and a frame element are provided that facilitate multiple connection options for a vertically-mounted acoustic baffle in a single system. Kits comprising the clip, frame element and an acoustic baffle are also provided.

A corner hardware kit for completing a frame corner that is defined by a first frame element and a second frame element includes a corner bracket having a first portion for attachment to the first frame element and a second portion for attachment to the second frame element. The corner bracket has an upstanding foot that protrudes rearwardly therefrom and carries a coupling member at a distal end thereof. The kit also includes an elastic corner insert that has a curved outer surface and has a pair of first coupling elements for mating to a pair of second coupling elements that are associated with the first and second frame elements to complete the corner of the frame.

A modular wall overlay system for installation on a support surface includes a frame; and a cover securely retained on the frame by a tensioning system whereby the cover is free of direct attachment to the frame but rather is retained under tension on the frame by the tensioning system. The frame includes a plurality of frame pieces and a plurality of corner brackets. The frame pieces are directly coupled to respective corner brackets but are free of direct coupling to one another.

A modular wall overlay system for installation on a support surface includes a frame; a cover that is securely, yet detachably, retained on and along a front face of the frame by a tensioning mechanism that is configured to tension the cover; and elastic corner inserts that are disposed in corners of the frame and include curved outer surfaces that are configured to permit the cover to be stretched over the elastic corner inserts creating radiused corners and preventing tearing of the cover in corners thereof when the cover is tensioned by the tensioning mechanism.

A modular wall overlay system for installation on a support surface includes an outer frame having a pair of opposing ends and a pair of opposing sides and a customizable inner frame that is coupled to the outer frame. The inner frame includes a plurality of transverse supports that extend between the opposing sides and a plurality of longitudinal supports that extend between the opposing ends. The longitudinal supports and the transverse supports lie in a common plane defined within the outer frame. The system further includes a cover that is securely retained on the outer frame.

A corner hardware kit for completing a frame corner that is defined by a first frame element and a second frame element includes a corner bracket having a first portion for attachment to the first frame element and a second portion for attachment to the second frame element. The corner bracket has an upstanding foot that protrudes rearwardly therefrom and carries a coupling member at a distal end thereof. The kit also includes an elastic corner insert that has a curved outer surface and has a pair of first coupling elements for mating to a pair of second coupling elements that are associated with the first and second frame elements to complete the corner of the frame.

An improved sound reducing panel is disclosed comprising a front porous sheet for enabling sound to enter into the sound reducing panel and a rear non-porous sheet. A sound absorbing member dissipates sound entering into the front porous sheet. A sound blocking member blocks sound from exiting from the sound absorbing member. A decoupling member reduces sonic vibration from being transferred from the sound blocking member to the rear non-porous sheet.

The present disclosure relates generally to acoustic panels, for example, suitable for acoustic ceiling surfaces. The present disclosure relates more particularly to acoustic panels that include a panel body (e.g., comprising fiberglass, or having an NRC value in the range of at least 0.5, e.g., 0.5-0.95 or 0.5-0.9) and a perimeter frame extending around a side edge of the panel body. The perimeter frame includes a plurality of frame members including a first frame member and a second frame member. A first adhesive bonds the frame members to the panel body. A second adhesive with a shorter working time may also bond the frame members to the panel body. In addition, or alternatively, a bracket that couples the frame members to one another includes a sharp projection that hinders removal of the bracket from the frame members once assembled. These aspects allow the acoustic panel to be handled before the first adhesive is cured.

Provided herein is a system for reducing the overall noise output of equipment used in the hydraulic fracturing of oil and gas wells, by providing a noise-reducing enclosure and/or radiator which substantially reduce the level of noise that reaches the environment during normal operation.

A passive ventilation panel and system, in particular for use in doors, ceilings, walls and partitions enables an exchange of supply and return air for at least one room or a room, without the need for additional ventilation equipment, such as ducts, and without the needs to install wall openings or grills for the supply and exhaust air in the space.
