In order to develop a fire-protection rolling door of the type in question such that the fire resistance duration and thermal insulation are improved and increased and in particular heat transfer points extending through the door are avoided, a fire-protection rolling door is proposed which is composed of: —a rolling-door armor of profiled plates which interconnected in an articulated manner; —a sheet-shaped intermediate layer of fire-retardant and thermally insulating material; and—overlapping cover plates, which fire-protection rolling door is held, in the open state, above an opening to be closed in the event of a fire, such that the fire-protection rolling door can be guided in guide rails disposed on both sides, the sheet-shaped intermediate layer having planar carrier segments, which are covered with at least one layer of fire-retardant and thermally insulating material on both sides.

A generator enclosure for an engine-generator includes multiple walls defining at least one air path. In one example, a first wall includes an exhaust path for the engine-generator, and a second wall includes an intake path for the engine-generator. The generator enclosure may include at least one air flow frame associated with the exhaust path or the intake path and at least one movable wall supported by the at least one air flow frame, At least one thermal fuse may be coupled to the at least one movable wall and configured to release the at least one movable wall to block the exhaust path or the intake path.

A fire damper including a frame and a plurality of blades rotatably mounted to the frame such that each blade is rotatable about a respective rotational axis between an open rotational position and a closed rotational position, each blade including at least one substantially planar portion; and a side edge portion which is curved away from a plane of the substantially planar portion, wherein a first curved side edge portion of a first of the blades is adapted to engage a second curved side edge portion of a second of the blades, adjacent the first, when the blades are in the closed position; and wherein the first curved side edge portion curves in an opposite direction to the second curved side edge portion when the first and second blades are engaged.

A slat assembly may include a slat having a first and second receiving portion. The first and second receiving portions being a pair of bent portions forming an acute angle. The slat assembly may further include an insulation layer lined on the slat. The slat assembly may further include a retaining mechanism disposed on the insulation layer to press a first portion of the insulation layer into the first receiving portion of the slat and to press a second portion of the insulation layer into the second receiving portion of the slat such that the retaining mechanism may cooperate with the first and second receiving portions to hold the insulation layer between the retaining mechanism and the slat without puncturing or penetrating the insulation layer with fasteners. A roller shutter including the slat assembly. A method of manufacturing a slat assembly and a method of manufacturing a roller shutter.

The present disclosure provides a non-powered open/close fireproof shutter including a shutter, a shutter track which is disposed in a horizontal direction and guides both end portions of the shutter in a width direction, a coil box in which a winding shaft for winding the shutter is installed to store the shutter in a coil form, a winding motor which rotates the winding shaft, and a weight which is connected to the shutter and deploys the shutter stored in the coil box along the shutter track. The non-powered open/close fireproof shutter according to the present disclosure can significantly reduce initial facility investment and maintenance costs, prevents malfunction of the fireproof shutter, which may occur when power is lost due to a loss of an emergency power source, in advance, and can secure reliability of a fire blocking function.
