Abstract
A sectional garage door panel formed by a member including a front wall, top and bottom edges and spaced apart back wall parts defining an interior space which is partially filled with an expandable PUR foam insulation material. A rigid polystyrene insulation member is placed in the interior space and bonded to the expanding foam material. The panel is placed in a laminator to secure the insulation member in the panel interior space during foam expansion and to provide for forced foam expansion into spaces defining panel top and bottom edges. A sheet backer is adhesively bonded to the insulation member and the back wall parts. A system includes conveyors, foam and adhesive dispensing nozzle arrays and a laminator including conveyor belts which hold the insulation member forcibly within the interior space of the panel during foam expansion and curing.
