ABSTRACT:
A door has a pair of spaced stiles at its side edges, a top rail extending between the upper ends of the rails, and a pair of synthetic resin skins providing the faces of the door and adhesively bonded to the stiles and rail. The skins have opposed flanges along their top and bottom edges which abut to form top and bottom peripheral walls, and they also have opposing spaced lips along the side edges thereof which extend along a portion of the outer surfaces of the stiles. The peripheral walls provided by the flanges have vent openings extending therethrough, and a cellular synthetic resin core is bonded to the skins and fills the interior space between the skins bounded by the stiles, rail and bottom flange. Baffled passages are provided between the vent openings and the interior space. In making She door, after the skins have been assembled and adhered to the stiles and rails, the stiles and flanges effectively seal the interior space which they define and this assembly is placed in a heated press. As a foamable resin mixture is injected under pressure into the interior space and expands therein, air is expelled through the baffled passages and vent openings, and the press precludes bowing outwardly of the skins.
