series  ESF 9/... ZK
contraction and sound insulation joints
 

Material:
Stainless steel side plates with perforated mounting brackets.
Flexible insert made of cellular rubber.



Standard colour grey
Special colour black
Production length 3 m

Special Properties:

  • Good fixing by perforated mounting brackets.
  • Reduced visible width of profile (only 9 mm).
  • Extra sound insulation can be obtained by installing insulation material as a joint filler.

Installation instructions:
A 5 mm thick joint filler strip must be placed between the aluminium mounting brackets. The height of joint filler depends on the overall height required, but it must be sufficient to ensure that the screed is completely separated at the joint locations. This strip also helps levelling the profile. The perforated legs of the profile are pressed into the first fresh layer of mortar or screed and levelled. Then more screed is applied.
Depending on the thickness of the floor finish (measured from top edge of profile) the profile must oversail the screed to suit.
