IS3070si(IS3100si) Threshold Seal

Ideal for sealing the gap between the door bottom
and the floor - a commonly overlooked area that is
essential to achieve containment.

The IS3070si weather resistant door bottom seal can be fitted
without removing the door, and can be used with alternative
threshold plates. This seal provides effective containment against
cold smoke, sound, dust, light, insects and weather. The aesthetic
cover strip ensures there is no visible screw line.
The IS3100si set incorporates an IS3070si door bottom seal plus
an IS4100 threshold plate.
