AF COVER STRING

AF COVER STRING is certified to protect small service installation penetrations on REI 120 false ceilings, including electrical cables, corrugated pipes, suspension chains, threaded rods, etc.

Membrane false ceilings are excluded.

When combined with AF SEAL W sealant, AF COVER STRING is an effective protection system, easy to install and does not overload the false ceiling.

 

AF COVER STRING is a rock-wool cylinder covered with aluminium foil with a longitudinal cut that enables its opening.

Once placed around the element to be protected in the false ceiling extrados, the remaining space between the inner surface of the cylindrical element and the element to be protected must be filled with the AF SEAL W firestop sealant. The assembled product guarantees REI 120 class fire resistance.
