ACTIFOAM Installation Steps

ACTIFOAM Firestop is simple to install, making it easier to achieve an effective fire protective, gas tight and water tight seal and saving installation time and cost. See the installation instructions for ACTIFOAM Firestop cable and pipe sealing systems below.

STEP 1

STEP 1

If the walls inside the conduit opening exhibit large irregularities, they should be locally smoothed with FIWA (or NOFIRNO) fireproof sealant, otherwise insufficient smoke tightness will be obtained.

STEP 2

STEP 2

The cables can be ducted through the conduit opening in random order. It is important that they are not pulled too tight in order not to hamper their separation.

STEP 3

STEP 3

ACTIFOAM rubber sheets are cut into strips fitting to the size of the walls inside the conduit opening. For this purpose ACTIFOAM sheets with a thickness of 25mm are used.

STEP 4

STEP 4

The ACTIFOAM rubber sheets should fit snuggly in the conduit opening to ensure a tight fit against the walls. This is important to avoid smoke penetrating between the sheets and the wall.

STEP 5

STEP 5

An ACTIFOAM rubber sheet must also be placed in the conduit opening underneath the layer of cables. A band is placed around the cable bundle to lift the bundle of cables.

STEP 6

STEP 6

A slightly oversized strip of ACTIFOAM rubber with a thickness of 25mm is placed inside the conduit opening underneath the cables. The sheet will be compressed by the weight of the cables.

STEP 7

STEP 7

One layer of cables is spread out on the ACTIFOAM rubber sheet at the bottom of the conduit opening. The other cables are lifted to make room for further finishing to the first layer.

STEP 8

STEP 8

For proper cable separation, square profiles are torn off the pre-slit ACTIFOAM rubber sheets. The sizes of the profiles should be simillar to the cable diameters.

STEP 9

STEP 9

Profiles are slit in sizes of 10x10, 15x15, 20x20 and 25x25mm. This enables an easy fit for corresponding cable sizes. Cables larger than 25mm should be separated by a minimum of 25mm.

STEP 10

STEP 10

Adjacent to the first layer of cables and profiles, one or more extra sheets of ACTIFOAM rubber is fitted to create a level layer for further filling the conduit opening.

STEP 11

STEP 11

An intermediate ACTIFOAM rubber sheet is inserted in the conduit opening on top of the levelled first layer. The thickness of the intermediate layer is dependent on the maximum cable diameter.

STEP 12

STEP 12

The next layer of cables is spread out on the ACTIFOAM intermediate rubber sheet. As indicated before, the cables should not be pulled too tight to enable this.

STEP 13

STEP 13

In the same way as with the first layer of cables, the cables are separated with the ACTIFOAM pre-slit profiles and levelled with one or more ACTIFOAM sheets.

STEP 14

STEP 14

The remaining space is filled with one or more ACTIFOAM sheets. All sheets should fit tightly in the conduit opening to obtain a fair degree of smoke tightness.

STEP 15

STEP 15

Due to better sliding of greased rubber on rubber and for final finishing, an ACTIFOAM sheet must be inserted between the top layers of ACTIFOAM sheets.

STEP 16

STEP 16

Compression of the filling is necessary to obtain stability. For this purpose it is easier to insert a couple of strips instead of sheets. The strips are greased all around with CSD lubricant.

STEP 17

STEP 17

The first strip is inserted into the opening between the layers by hand. For a wall thickness of 150mm, it is advisable to cut three strips 50mm wide to enable easier insertion.

STEP 18

STEP 18

A piece of wood is used to push the strips tightly into the opening between the ACTIFOAM rubber sheets. The use of strips instead of sheets makes this much easier to do.

STEP 19

STEP 19

The finished ACTIFOAM multi-cable penetration. Officially fire tested according to BSEN 1366-3 (NEN 6069) for 2 hours in an aerated concrete wall 150mm thick.

STEP 20

STEP 20

In case the penetration has to be not only fire safe but also gas and watertight, the ACTIFOAM foam rubber filling can be covered with a layer of FIWA (or NOFIRNO) sealant in a minimum thickness of 10mm.

STEP 21

STEP 21

It is not necessary to interrupt the cable tray. ACTIFOAM allows, if required, the tray to be passed thorough the conduit opening. ACTIFOAM sheets are placed around the cable tray.

STEP 1

STEP 1

If the walls inside the conduit opening exhibit large irregularities, they should be locally smoothed with FIWA (or NOFIRNO) fireproof sealant, otherwise insufficient smoke tightness will be obtained.

STEP 2

The cables can be ducted through the conduit opening in random order. It is important that they are not pulled too tight in order not to hamper their separation.

STEP 1

STEP 1

The conduit opening has to be 25mm smaller all around than the inner dimensions of the FIRESTOP. This will keep the rubber pads against the walls inside the FIRESTOP in place during fire exposure.

STEP 2

STEP 2

If the wall around the conduit opening exhibits large irregularities, they should be locally smoothed with FIWA (or NOFIRNO) fire safe sealant. This is to prevent smoke emission between the FIRESTOP and the wall.

STEP 3

STEP 3

Remove the attachment bracket and the cover of the FIRESTOP. Remove all ACTIFOAM rubber pads with the exception of the bottom layer and the layers against the side walls of the casing.

STEP 4

STEP 4

The casing is used as a template to mark off the attachment holes. The ACTIFOAM rubber pads against the inside walls of the FIRESTOP are 25mm thick and should be flush with the conduit opening.

STEP 5

STEP 5

Then drill the holes for the anchoring bolts. After the bolts have been positioned, push all parts of the fire resistant FRR/HF gasket over the anchoring bolts and lay them against the wall.

STEP 6

STEP 6

The casing containing the bottom layer of ACTIFOAM rubber pads and the rubber pads against the side walls, is pushed over the anchoring bolts against the wall and firmly tightened.

STEP 7

STEP 7

Position the attachment bracket on the casing against the wall and mark off the attachment holes. If necessary, the holes in the upper parts of the gasket can also be used for this purpose.

STEP 8

STEP 8

After drilling, position the anchoring bolts and the attachment bracket. Do not tighten the bracket firmly, in order to facilitate insertion of the top layer of rubber pads later during installation.

STEP 9

STEP 9

In case of larger amounts of cables, a band is placed around the cable bundle to lift the bundle of cables. ACTIFOAM rubber pads are placed in the FIRESTOP underneath the layer of cables.

STEP 10

STEP 10

A layer of cables is spread out. For proper cable separation, square profiles are torn off the pre-slit ACTIFOAM rubber sheets. The sizes of the profiles should be equivalent to the cable diameters.

STEP 11

STEP 11

Profiles are slit in sizes of 10x10, 15x15, 20x20 and 25x25mm. This enables an easy fit for corresponding cable sizes. Cables larger than 25mm should be separated by a minimum of 25mm.

STEP 16

STEP 16

The remaining space is filled with layers of ACTIFOAM pads. The filling should be flush with the top side of the FIRESTOP casing. For this purpose the pads are available 10,15, 20 and 25mm thick.

STEP 18

STEP 18

Place the cover on the FIRESTOP casing and fit the attachment bolts in the holes. The attachment bolts are long enough to put the nuts on easily despite the overfill of 10mm inside the FIRESTOP.

STEP 19

STEP 19

Tighten the attachment bolts firmly. With respect to mechanical stability and tightness, it is very important to check if the overfill is sufficient to obtain an optimum compressibility.

STEP 20

STEP 20

Place rings and nuts on all the remaining anchor bolts and tighten the attachment bolts of the attachment bracket firmly.

STEP 1

STEP 1

The conduit opening has to be 25mm smaller all around than the inner dimensions of the FIRESTOP. This will keep the rubber pads against the walls inside the FIRESTOP in place during fire exposure.
