The FIRESTOP Applic 38 automatic drop down seals are designed to form an effective barrier against the outside climate, including noise, light, fire, smoke and insects, and are activated by the closing action of the door, meaning that the seal only drops down when the door is closed. The seals are available in a variety of lengths and can be cut down to size and are supplied complete with screws, to ensure quick and easy fitting on either the inside or the outside of the door. The seals are acoustically tested in accordance with DIN EN ISO 10140-2 achieving a rating of up to 38dB Rw. They are fire tested to BS EN 1634-1 and smoke tested to BS EN 1634-3: 2004.
