Abstract
Reinforced door incorporates sheet steel panels on each side of a supporting metal framework where the spaces between the panels and the framework are filled with a material providing thermal and acoustic insulation, pref. a fire retardant polyurethane foam. The borders of the door are enclosed by four lengths of timber. The prod. is used esp. for entrance doors within blocks of apartments or flats. The structure combines security with acoustic insulation without being excessively heavy or unsightly.
