FEW COMPONENTS TO KEEP INSTALLATION COMPREHENSIBLE
|
In developing the FIRSTO firestop on the basis of the ACTIFOAM technology, it was sought to keep the number of components to the absolute minimum. Basically, the FIRSTO firestop consists of
- a metal enclosure,
- a firesafe filling with ACTIFOAM sheets and
- a set of gaskets. |
 |
The metal enclosure consists of a casing (a), an attachment bracket (b) and a cover (c).
Angle-irons are positioned below the casing and on the cover to ensure sufficient stability under fire
load.
A fireproof gasket (d) is fitted between the casing and the wall or
floor. Inside the enclosure, fireproof ACTIFOAM sheets (e) are placed all round against
the walls of the casing and below the cover.
The space around the cable tray and in between the cables is packed with ACTIFOAM sheets cut to size or ACTIFOAM pre-slit sheets (f).
Height adapters (g) are placed between the casing and the cover to enable the firestop to be adjusted in height
to the existing conduit opening.
Length adapters (h) are placed between the sides of the casing and the cover in order to adjust the firestop in length to the existing conduit opening. |
| The enclosure casing is not used in the case of floor conduits in front of a wall. In such situations, the side walls of the firestop are assembled with the aid of height adapters. The covers and attachment brackets correspond with those of the firestops for wall conduits. Gaskets are placed on the floor and against the wall. |
