A door (10) made in accordance with the present invention includes a plurality of panels (20) with opposed stiles (24, 25) being positioned at the longitudinal edges of a faceplate (21) of each panel (20) and with opposed rails (26, 27) being positioned at the lateral edges of the faceplate (21) of each panel (20). An insulation assembly (30) includes a sheet of insulation material (31) and a backing sheet (32) which has edges (33) which overhang the lateral edges of the sheet of insulation material (31). The insulation assembly (30) is installed in the door (10) by engaging the stiles (24, 25) with the longitudinal edges of the sheet of insulation material (31) to flex the same until the edges are received in notches (34) formed in the stiles (24, 25). Then the overhanging edges (33) of the backing sheet (32) engage the rails (26, 27) and deform to press the sheet of insulation material (31) against the faceplate (21).
A door comprising a plurality of panels, each said panel having opposed rails and a faceplate extending laterally between said rails, a sheet of insulation material having laterally spaced edges positioned adjacent to said rails, and a backing sheet attached to said sheet of insulation material and having lateral edges overhanging the lateral edges of said sheet of insulation material such that the lateral edges of said backing sheet engage said rails to hold said sheet of insulation material against said faceplate.
A method of assembling a door having laterally spaced rails and a faceplate extending between the rails, comprising the steps of attaching a backing sheet to a sheet of insulation material with the backing sheet having lateral edges overhanging the sheet of insulation material, and engaging the rails with the lateral edges of the backing sheet to press the sheet of insulation material against the faceplate.
A method of installing an insulation material, having a backing sheet with a portion overhanging the lateral edges of the material, into a panel of a door having a faceplate with lateral edges defined by rails and longitudinal edges defined by stiles, comprising the steps of positioning the longitudinal edges of the insulation material adjacent to the stiles, and bringing the overhanging portion of the backing sheet into engagement with the rails to deform the overhanging portion thereby pressing the insulation material against the faceplate.
A sectional door panel comprising a pair of spaced rails, at least two stiles extending between said rails, a faceplate integral with and extending between said rails and overlying said stiles, an insulating sheet extending between said stiles and proximate said rails, and means associated with said insulating sheet engaging said rails for maintaining said insulating sheet pressed against said faceplate.
