An insulated door for refrigerators, freezers or similar cabinets where the inner and outer door surfaces are normally subjected to substantially different temperatures. The main door components, the door face and drum, are interconnected without the use of threaded fasteners such as screws or bolts. Instead a hardened, foamed in situ insulating material forms the main interconnection between the door face and drum, securing them together but yet accommodating thermally induced, relative movement between the two components. In constructing the door S-shaped retainers are used which receive in their oppositely opening loops the edges of the face and drum. Temporary spacers are then interposed between the face and drum edges for the foaming operation. Following the filling of the door cavity with insulating material the spacers are removed and an anchoring leg of a gasket is snapped into place into the cavity left by the removal of the spacers, securing the gasket to the door without the use of screws or other mechanical fasteners, but permitting gasket to be removed as necessary for replacement or repair.
