HOW IS FIRETIGHT® INSTALLED?

FAST AND EASY INSTALLATION.

FIRETIGHT® is placed entirely in the joint. After puncture, the high density mineral wool recuperates immediately and completely fills the cavity. Due to the excess, FIRETIGHT® remains in place without additional measures, with the intumescent layer being positioned correctly at the same time. The film remains in the seam and seals it in an airtight manner. FIRETIGHT® products can easily be placed in a row to fill the complete length of the joint.

On this page you will find the complete installation instructions.

FIRETIGHT® in compressed and activated state

STEP 1
Define needs

FIRETIGHT® can be used in joints and seams with a width of 40 to 160 mm. The application the FIRETIGHT® is based on the joint width of your project. Use FIRETIGHTs® in a single or double manner based on your joint or seam width.

JOINT WIDTH	APPLICATION
40 – 90 mm	SINGLE FIRETIGHT®
90 – 160 mm	DOUBLE FIRETIGHT®

For a good fire protection, the thickness of the product is 1,5x the width of the joint or seam. Check if the width of the joint and the thickness of the FIRETIGHT® are according to advised guidelines before use. When the guidelines are followed, the FIRETIGHT® does not need additional support for a permanent placement.

Based on the joinwidth of your project, FIRETIGHT® must be placed in a single or double manner (see the table above).

SINGLE or DOUBLE

STEP 2
PLACE FIRETIGHT®

SINGLE FIRETIGHT®

The FIRETIGHT® can be applied in the seam both from above and below. It is possible the seam is closed on the end(s). If this is the case, fold the protruding part of the packaging back slightly on the end side (see image 1)and place the edge against the end of the seam (see image 2). Make sure that the mineral wool is placed as close to the short end of the seam as possible.

In the case of an open seam, the FIRETIGHT® is simply
positioned at the end.

STEP 3
Activate FIRETIGHT®

SINGLE FIRETIGHT®

After the FIRETIGHT® has been inserted into the seam, it must be pressed against the end with one hand and held in position. With the other hand, cut the foil with a sharp knife over a length of about 5cm, which will break the vacuum. The mineral wool recuperates and clamps itself in the seam (see image 3).

STEP 4
Continue installation

SINGLE FIRETIGHT®

Now place the next FIRETIGHT® in the seam so the protruding foil of the placed FIRETIGHT® lies opposite to the protruding foil of the next FIRETIGHT®. The FIRETIGHT®s are then placed, alternating one and the other (see illustration).

After the 2nd FIRETIGHT® has been inserted into the seam, it must be pressed against the first FIRETIGHT® with one hand and held in position (see image 4). With the other hand, cut the foil again with a sharp knife over a length of about 5cm to release the vacuum and to allow the mineral wool to recuperate (see image 5).

Continue working like this until it is clear that, with the next
FIRETIGHT®, the seam is completely filled (see image 6).

NEXT STEP

STEP 5
Install end cap

SINGLE FIRETIGHT®

When the seam ends with a closed end, self-adhesive
intumescent tape should be applied before the last
FIRETIGHT® is placed.

Cut off a piece of intumescent adhesive tape to size
and stick it on the closed end (see image 7).

Now place the last FIRETIGHT®:

Measure the remaining seam to be filled and determine the length of the remainder (use the FIRETIGHT®clamp if necessary) (see image 8).
Mark the FIRETIGHT®;
The FIRETIGHT® is then inserted into the seam at an angle and cut to size with a sharp knife (see image 9). When you are cutting, the mineral wool will immediately recuperate, which is why the FIRETIGHT® must be at least partially placed in the seam before commencing with cutting. The film allows the FIRETIGHT® to be slid into place in the seam. The cut edge has to be placed
against the short closed end of the already applied intumescent band. After the FIRETIGHT® has completely recuperated, remove the Firetight clamp (see images 10 through 12).

If the seam does not have a definite end but ends in free space, the part of the FIRETIGHT® which sticks out can be easily cut off (see image 13).

PROTECTED

SINGLE FIRETIGHT®

The seam is now fully fire-resistant (see image 14 and 15).

INSTRUCTIONS FOR DOUBLE FIRETIGHT®

Below you’ll find a detailed description of the installation for the double FIRETIGHT®.

STEP 2
PLACE FIRETIGHT®

DOUBLE FIRETIGHT®

The FIRETIGHT® can be applied in the seam both from above and below.
It is possible the seam is closed on the end(s). If this is the case, please apply a self-adhesive intumescent tape to the inside of the end of the seam. Cut a piece of the self-adhesive intumescent tape to size and stick this to the short end of the seam (see image 1).

The FIRETIGHT® strips should be placed in the seam in an alternating fashion.

To do this, fold the protruding part of the packaging back slightly at the end (see image 2), and place the edge against the end of the seam (see image 3). Make sure that the mineral wool is placed as far as possible against the end of the seam. Place a second FIRETIGHT® on the same side of the seam against the end of the first FIRETIGHT®.

The two FIRETIGHT®s are now laying end-to-end in an alternating fashion (see image 4). Hold this FIRETIGHT® in place in the seam with your hand.

Now place the third FIRETIGHT® on the opposite side against the first and second FIRETIGHT® in the pattern as shown in the illustration. The third FIRETIGHT® is now halfway between the first and second FIRETIGHT® (see image 5).

If the seam is not closed, the FIRETIGHT® is simply positioned at the end, also see step 6.

NEXT STEP

STEP 3
Activate FIRETIGHT®

DOUBLE FIRETIGHT®

After the FIRETIGHT®s have been inserted into the seam, they must be held in position. Then cut the foil of the third FIRETIGHT® with a sharp knife over a length of about 5cm. This will break the vacuum.

The mineral wool recuperates and clamps itself in the seam (see image 6). At this stage, leave the first and second FIRETIGHT® intact for a while. The position of these FIRETIGHT®s can still be easily adjusted so that the strips can be properly connected to each other.

NEXT STEP

STEP 4
Install end cap on closed end

DOUBLE FIRETIGHT®

Position the missing FIRETIGHT® using the FIRETIGHT®clamp.

Slide the Firetight clamp over the FIRETIGHT® with the open bottom underneath (see image 7).
Measure the length of the remainder and mark the FIRETIGHT® (see image 8).
The FIRETIGHT® is then inserted into the seam at an angle and cut to size with a sharp knife (see image 9). When you are cutting, the mineral wool will immediately recuperate, which is why the FIRETIGHT® must be at least partially placed in the seam before you commence with cutting. The film allows the FIRETIGHT® to be slid into place in the seam. The cut edge has to be placed against the short end of the already applied intumescent band.
After the cut-to-size FIRETIGHT® has completely recuperated, remove the FIRETIGHT®clamp. The first FIRETIGHT® can now be activated by cutting through the foil (see image 10). The FIRETIGHT®s wil now fill the entire seam and connect well to each other on the short sides (see image 11).

NEXT STEP

STEP 5
Continue installation

DOUBLE FIRETIGHT®

Now place the next FIRETIGHT® in the seam opposite of the protruding FIRETIGHT®.

This FIRETIGHT® can now be recuperated by cutting into the foil. Continue until the entire seam is filled (see image 12).

In the case of a closed end, repeat step 4. Proceed with step 6 in the case of an open end.

NEXT STEP

STEP 6
Install end cap on open end

DOUBLE FIRETIGHT®

If a seam has an open end, for example because the connecting building element has not yet been placed, the last FIRETIGHT®s must simply protrude. The protruding parts are then cut off (see image 13).
