Safe building
In fire-safe buildings, the details determine
the effectiveness. The joint width and the
wall thickness therefore need to be indicated
if fire resistance is specified. By using fire-
resistant Cocoband 6069, fire penetration,
smoke and toxic gases are held back. The
Construction Decree places requirements
on resistance to fire penetration and fire
spreading (WBDBO) between
compartments (also in residential
construction).

Working recommendation
Cocoband 6069
Joint dimension
● Minimum 2 mm.
● Maximum 30 mm.
The fire resistance of Cocoband 6069
depends on:
● the joint width
● the joint depth (wall thickness)
● the type of structure.
Joint dimension l minimum 2 mm l maximum
30 mm. Strip choice: choose the right strip
dimension for each joint width.
For example: joint width 12 mm strip
choice 30/12 or 40/12. 30 and 40 is the
strip width (the deeper the joint fill, the
broader the strip). Place a fire-resistant strip
on both sides of the wall. Wall thickness: 100
mm. Joint depth 80 mm filled.
● Strip +10° C to +25° C.
Substrates
● The substrates should be free of dust
and grease.
Working
The compression factor dictates the
functional requirements for the joint sealing.
This is the factor with which the maximum
joint width is multiplied. Whenever fire
resistance is required, this means a
compression factor of 5x the joint width (=
strip thickness in expanded form). The
minimum joint depth (= strip width) is 20 mm
for joints up to ≤ 10 mm and 30 mm for larger
joints.
● The strip can be placed in the joint directly from the roll.
● Corners and splices need to be
applied carefully.
● Cocoband 6069 should never be
drawn around a corner.
● Always cut splice connections and
butt the strip with excess length.
NEN 6069 experimental determination of the
fire resistance of building parts.
In determining fire resistance, the behavior
needs to be determined by means of one or
more specimens under the influence of
heating according to standardized fire
conditions,
illbruck Sealant Systems B.V. produces,
besides Cocoband 6069, also a number of fire-
resistant joint sealant systems per NEN 6069.
