About this detail

A sound-insulated steel door assembly features a 16-gauge cold-rolled steel welded one-piece frame with an integral stop, backed by metal stud jamb framing. The frame cavity is packed with mineral wool insulation for acoustic performance. A Pemko S-88 gasket and Pemko 29310CS jamb and head seals are set in acoustic sealant along the stop to prevent sound transmission. The sound-insulated steel door closes against the framed opening, with a mortise automatic drop bottom and a Pemko 434ARL threshold set in sealant at the sill.
