US Patent:

20070098997, May 3, 2007

Filed:

Nov 2, 2005

Appl. No.:

11/264890

Inventors:

Usama Younes - McMurray PA, US
James Kotar - McMurray PA, US
James Lambach - McMurray PA, US
John Perry - Scenery Hill PA, US

International Classification:

B32B 27/40

US Classification:

428423100

Abstract:

Weather resistant composite articles which have a smooth, bubble-free surface and are sufficiently puncture resistant to pass the DynaTup Instrument Impact Test are produced by an open pour process. These composites include a polyurethane, unreinforced barrier coat and a fiber-reinforced polyurethane layer. These composite articles are particularly useful for the production of doors and panels.

International Classification:

B32B 27/12

US Classification:

428301400

Abstract:

Weather resistant composite articles which have a smooth, bubble-free surface and are sufficiently puncture resistant to pass the DynaTup Instrument Impact Test and have sufficient structural integrity and strength characteristics are produced by an open pour process. These composites include a polyurethane, unreinforced barrier coat and a fiber-reinforced polyurethane layer. These composite articles are particularly useful for the production of doors and panels and as structural components for spas, hot tubs, above ground pools and the like.

Appl. No.:

17/053177

Inventors:

- Pittsburgh PA, US
James L. Lambach - McMurray PA, US

International Classification:

E04C 2/38
E04B 2/70

Abstract:

Wall structures and methods of manufacturing wall structures are described. The wall structures include a frame, a foam panel attached to the frame, a brace disposed in a cavity defined by the frame, and a foam layer. The wall structures can impart a high wall racking strength and good thermal performance through the combination of the foam layer, brace, and the foam panels.

International Classification:

E04C 2/38
E04B 1/26
E04B 1/343
E04B 2/56
E04B 1/74

Abstract:

Modified and connected foam wall structures and methods for making them are described. The wall structures include a frame, a foam panel attached to the frame, a foam layer disposed in a cavity defined by the frame, and a structural adhesive. The structural adhesive may be disposed in at least one of: (A) an aperture located within the foam layer, and (B) an aperture located between the foam layer and a frame member. In some cases, a cured structural adhesive is located between connecting members of adjacent foam wall structures.

Appl. No.:

16/529012

Inventors:

- Pittsburgh PA, US
James L. Lambach - McMurray PA, US
David M. Baily - Upper Saint Clair PA, US

International Classification:

E04C 2/292
B29C 44/12

E04B 1/14
E04C 2/38
B29C 44/18
E04C 2/20
B29C 44/34

Abstract:

Methods of manufacturing wall structures having high racking strength are described in this specification. The methods include spray applying a foam-forming composition into a cavity of a wall structure, wherein the wall structure is disposed in a climate-controlled spray application station and allowing the foam-forming material to expand within at least a portion of the cavity to form a foam layer deposited in the cavity. In the methods, the foam layer is formed in-situ during the manufacturing method, and the density of the foam layer is selected and the relative humidity and dew point of the air in the climate-controlled spray application station throughout the spray applying is selected so that the wall structure has a racking strength of at least 500 pounds per linear foot.
