IS 8010si automatic threshold seal is a drop down seal with a high efficiency mechanism which lifts the seal clear of the floor as soon as the door is opened by a few millimetres. It requires no power connection. It can be used in fire doors with the addition of an intumescent cladding kit. When fitted to the ‘EWOOD’ veneered door in a suitable frame with the correct acoustic seal arrangement it will achieve up to 32dB sound reduction.
