A mounting rail for mounting tiles to a backing system of a building wall structure comprises a tile support linked with a back-fixing rail via a tile-support carrier. The tile-support carrier comprises an acoustic damper between the tile support and the back-fixing rail. This impedes the transmission of acoustic energy from the tiles to the backing system, and so improves the acoustic insolation while the mechanical stiffness of the tile-support carrying arm is maintained. The acoustic damper may be provided in the form of one or more angled bends, apertures, an obtusely angled connection of the tile-support carrier to the back-fixing rail or a connection of the tile-support carrier at an upper or lower end of the back-fixing rail, or combinations of two or more of these features.

An acoustic mount is described for damping vibrations between a primary structure of a building and a secondary structure of a building and which has a vibration damper interposed in use between the primary and secondary structures. The vibration damper is resiliently compressible in the axial direction and has at least one resiliently compressible damper element which is elongated in the axial direction so that the axial length of the damper element is greater than half of a transverse width thereof. The damper element reduces in cross sectional area in the axial direction; has a convex outer surface in planes containing the axial direction; and possesses non-linear axial deflection or compression characteristics under a range of static loading conditions enabling effective vibration damping or vibration isolation for a substantial range of loadings of the acoustic mount in use. Damper elements have a continuous convexity of outer surface extending to a tip and the continuous convex outer surface in a plane containing the axial direction has a curved shape defined by a quadratic equation, including segments of ellipses, parabolas, hyperbolas.

A sound isolation assembly comprising: a center ferrule; a top grommet isolator; a bottom grommet isolator; a spring; and a furring channel engagement portion. The sound isolation assembly is configured to engage with a structure and a furring channel, which itself is connected to a ceiling panel, such that the noise passing from one floor to the other is lessened as compared to a control system that does not use the sound isolation assembly. The spring may be steel and the grommet isolators may be rubber or the like, and the combination of the steel spring and grommet isolators reduces noise.

A sound control firestop device. It has a horizontal pad portion made from an elastomeric or fibrous material with a first surface and a second surface opposite the first surface, the horizontal pad portion having a length and a width; and a vertical projection spacer portion projecting outwardly from the second surface, wherein the vertical projection portion extends across at least a portion of the width of the horizontal pad portion. A method of installation thereof.

A deflect-plate for a frame of a building includes a lower wall, an upper wall above the lower wall and in spaced apart facing relation with the lower wall, and a plurality of spring members connecting the lower wall to the upper wall. In some embodiments, a first one of the spring members deflects inwardly in response to a vertical force on the upper wall, and a second one of the spring members deflects inwardly in response to a vertical force on the upper wall.

An insulation support system preferably includes an edge-folded ceiling liner sheet, an encapsulated package and a plurality of compressible thermal spacers. The edge-folded ceiling liner sheet includes opposed folded-up edges. The folded-up edges have sufficient length to clear pinch points along structural beams. The edge-folded ceiling liner sheet is fan-folded for retention in the encapsulated package. A pressure absorbing expansion spacer prevents roof or wall panel rumble noises and may be applied directly to roof or wall structural members, or may include a snap clip bonded to a pressure absorbing expansion spacer material. A bottom of the pressure absorbing expansion material is bonded to a top of the snap clip. The snap clip is attached to flanges of purlins or girts eliminating the need for stand-off roof panel clips, rigid thermal blocks and severe compression of an extra layer of blanket fiber glass insulation.

A clip insulation for a furring channel clip, the clip insulation having a substantially planar bed portion having two opposed ends, the bed portion adapted to at least cover a portion of an outer surface of the clip, a plurality of projections extending from the bed portion, and two opposed skirt portions, each skirt portion extending from an end of the bed portion, each skirt portion adapted to attach to an end of the clip.

It has a horizontal pad portion made from an elastomeric or fibrous material with a first surface and a second surface opposite the first surface, the horizontal pad portion having a length and a width; and a vertical projection spacer portion projecting outwardly from the second surface, wherein the vertical projection portion extends across at least a portion of the width of the horizontal pad portion. A method of installation thereof.

An infill wall support clip is described. The infill wall support clip provides lateral bracing for wall panels in residential or commercial buildings. The infill wall support clip anchors to a top track of wall panels and to a bottom track of a floor truss. The infill wall support clip provides spacing between the wall panel and the floor truss such that drywall may be continuously overlaid on top of the wall panel.
