An insulation system includes insulation support wires connected to wooden structural members that support roof sheathing. Insulation batts are disposed between the wooden structural members and on the insulation support wire. Portions of the insulation batts are disposed directly under bottommost surfaces of the wooden structural members.

A holder for supporting a material such as insulation. The holder includes a support member having a first and a second wire element for supporting the material, with each of the first and second wire elements having a first end and a second end adapted to engage two beams. The first and second wire elements also are coupled together by a serpentine section defining a planar holding surface. The second ends include U-shaped clamping members.

A precursor to form an impaling clip, and an impaling clip formed therefrom. The impaling clip is configured for mounting an acoustic panel on a structural component, e.g., a wall stud, of a building. The impaling clip includes a base member from which a pair of prongs project upward perpendicular to the plane of the base member. The base member includes at least one hole for receipt of a fastener, e.g., a screw, to fixedly secure the base member of the clip to the structural component. Each prong includes a leg portion terminating in pointed head and outwardly projecting under-cut barbs configured to pierce through the back surface of the panel to lock the prong within the panel so that it is resistant to removal.

An insulated wall system for a building includes a sheet assembly spanning across an opening in a building frame. The sheet assembly includes an outer plastic sheet member at an, an inner plastic sheet member at an interior, and a core layer of heat insulating material between the inner and outer sheet members. One or more perimeter boundaries of the sheet assembly includes a tensioning pocket formed on the inner sheet member to receive a frame member therein such that a tensioning mechanism can apply tension between the frame member in the pocket and a corresponding boundary of the building opening to tension the sheet assembly. The outer sheet member is joined to the inner sheet member about a perimeter while the core layer is bonded to both sheet members to transfer tension of the inner sheet member through all layers of the sheet assembly.

A method of using a self-stick insulation. The method includes providing a piece of insulation product with an adhesive coating. The adhesive coating includes polystyrene-maleic anhydride (SMA) and/or polyacrylic acid (PAA); an alcohol amine; and at least one of a polyvinyl alcohol and a starch. The adhesive coating is then activated with liquid water. Once the adhesive coating is active, the insulation product is attached to a surface with the adhesive coating.
