Closing and sealing against fumes and gas
If there are any gaps between the pipe and the wall, seal these
using putty or intumescent strips according to the thickness,
to prevent the passage of fumes in the event of a fire.
Cleaning the pipe
The expansion of the intumescent material in the collar com-
pletely closes the plastic pipes by a mechanical action. If the
pipes are very dirty or have mortar residues, this may delay
the action. Clean the surface of the plastic pipe in the point of
installation of the fire protection collars.
NB: the fire protection collar can only prevent the passage of
fire if it is properly installed
Precautions
In the case of contact of the intumescent material with the
eyes, wash delicately with soap and water. Keep out of the
reach of children.

Lightly-constructed partition walls
Angled wall and ceiling penetration to 45˚
For sealing over pipe collars (to 45˚)

On both sides of a wall; on one side under/in a ceiling
(see figure 37).
(2) Wall & ceiling types:
At least 10 cm thick solid concrete, aerated concrete and
sand-lime brick walls as well as light dividing walls (stud
walls: both sides clad with 12.5 mm plasterboard) and solid
concrete and aerated concrete ceilings at least 15 cm thick.
(3) Structural acoustic insulation:
The acoustic insulation mat provided must be wrapped
around the pipe where it passes through the wall or ceiling.
(4) Joint sealing between pipe and wall/ceiling:
To be packed to the full thickness of the wall or ceiling using
