Copolyester polyol resins comprising the reaction product of an aromatic component selected from phthalic derivatives, polyethylene terephthalate, or dimethyl terephthalate, an aliphatic component selected from certain dibasic compounds, at least one primary hydroxyl glycol, and at least small amounts of a secondary hydroxyl glycol, the mole ratios of the components being:

Copolyester polyol resins, polyol blends comprising the same, and

A composite panel for use in the construction industry includes a core of foamed plastic material and a skin on at least one of its faces comprised of a two-ply material consisting of aluminum foil bonded to a mat of randomly oriented glass fibers into which the foam core has been expanded. The core material comprises the rection product of isocyanurate and polyester/polyether polyol with the isocyanurate in sufficient excess to form trimmer rings and to react with the polyol to form urethane linkages. Panels formed of the core material and the two-ply skins have excellent thermal insulation and fire retardant properties and the skins have excellent mechanical strength.

Apparatus for fastening building construction insulating panels to a supporting wall structure comprising a slotted channel member and an anchoring clip. The channel has flanges by which it is secured to a supporting wall structure and a slotted mounting surface spaced from the supporting wall a preselected distance to provide improved insulation. The anchoring clip has opposed flanges on one end for engaging the edges of adjacent insulating wall panels and an anchor on the opposite end for engaging the slot in the channel and thereby holding the insulated panel to the supporting wall with the preselected spacing.

Insulating panel fastening system

Composite panels, each having a rigid board facing, made from gypsum, concrete, wood, or fibrous material, backed by a layer of foamed plastic insulating material whose reverse face is protected by a highly reflective, flame-retardant, moisture-vapor-proof material applied thereto, are held together edge-face to edge-face in building construction by special retaining clips which secure the panels to supporting structure, such as exterior, load-bearing walls, roof, or ceiling, and also serve to guide installation of the panels so that flush registry is assured without time consuming care in installing an additional panel relative to one already in place. The clip has flanges extending perpendicularly from lateral edges of a web strip whose width depends upon the use intended and the panel thickness. A flange along one edge of the web strip is adapted to be secured directly to the supporting structure. Flanges extending mutually oppositely along the other edge of the web strip are adapted to respectively penetrate the interfaces between insulating material and rigid board facings of mutually adjoining panels received by the clip. The outer extremity of the securement flange is formed as a ramp for deflecting a to-be-installed one of the mutually adjacent panels into proper flush position with respect to the one already installed. As an optional feature, the underside of the securement flange can also be provided with projections adapted to serve as spacers with respect to the structure against and to which it is secured.

Panel building construction and method, and clip

A composite panel-board is made up of a rigid, gypsum board, base panel having a rigid, organic plastic, foam layer formed in-situ on, self-adherent to, and essentially covering one of the broad, flat surfaces of the gypsum board base panel. A water-vapor-resistant, flame-retardant layer is adherent to and covers the otherwise exposed, broad surface of the rigid foam layer. The composite panel-board is fabricated by attaching upwardly extending edge sheets on or adjacent to the mutually opposite, side edges of the gypsum board panel so that the mutually opposite edge sheets, together with the gypsum board panel, form a trough. The upper surface of the gypsum board panel is heated to a temperature of at least about 95.degree. F in the presence of a water unsaturated atmosphere, and then a uniform layer of a foamable, liquid, organic plastic material is applied to the upper surface of the gypsum board panel. A sheet of water-vapor-resistant, flame-retardant material is applied to the exposed surface of the layer of liquid, organic plastic material immediately following the formation of such layer on the gypsum board panel, and the foamable, liquid organic plastic material then reacts and expands to form a layer of rigid foam which is self adherent to the gypsum board panel, the sheet of water-vapor-resistant, flame-retardant material, and the edge sheets.
