IS3021si 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 IS3015si and IS3016si seals are cleverly concealed in a rebated
groove in the meeting stile or bottom of the door leaf (respectively)
for single and double swing timber doors. These seals may be
surface mounted or rebated into doors to allow for depth adjustment
as required. Both seals can provide effective containment against
medium and ambient temperature smoke, sound, dust, light,
weather and vermin.
