Pressure absorbing expansion spacers
View Patent ↗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.
1. A system for retention adjacent a first sheeting panel and a second sheeting panel, comprising:
a pressure absorbing expansion spacer is attached to the first sheeting panel,
a bottom of a structural bracket is secured to the first sheeting panel; and
said pressure absorbing expansion spacer is placed in contact with the structural bracket and the second sheeting panel, the second sheeting panel is attached to a top of the structural bracket, the second sheeting panel is located above the first sheeting panel, wherein said pressure absorbing expansion spacer prevents the second sheeting panel from undulating relative to the first sheeting panel, said pressure absorbing expansion spacer prevents undulation when said pressure absorbing expansion spacer makes contact with the second sheeting panel, wherein said pressure absorbing expansion spacer prevents noise caused by the undulation of the second sheeting panel relative to the first sheeting panel.
2. The system of claim 1 wherein:
the second sheeting panel is one of a roof sheet or a wall sheet.
3. The system of claim 1 wherein:
said pressure absorbing expansion spacer is attached to the second sheeting panel with an adhesive or double sided tape.
4. The system of claim 1 wherein:
thermal insulation is installed adjacent the pressure absorbing expansion spacer to add thermal performance to the first sheeting panel.
