series  D 25/...  and  DE 25/...
expansion joints for facades, walls and ceilings (under plaster solution)

Material:
Aluminium side plates with perforated aluminium mounting brackets.

Flexible insert for exterior and interior use, weather resistant.

Standard colour grey
Special colours on request
(subject to min. quantitatives)
Production length 4 m


All profiles of series D 25/... and DE 25/... are also available in type D 12/... for use with plaster of 12 mm thickness.

 

Special Properties:

  • Good fixing and cohesion to plaster by perforated mounting brackets.
  • Double protection against water is possible for double fixed insert in aluminium profile.
  • Profile absorbs large movement (fold insert)
  • Profile absorbs settlements (insert is sliding within the metal profiles)
  • On request, the flexible insert is also available in one piece up to approx. 50 m max

INSTALLATION INSTRUCTIONS

The part of profile remaining visible after installation is protected from dirt during transport and plastering by an adhesive strip. The perforated side plates are fixed to the substrate with non-rusting steel nails (at distance of 30 cm).
Before the light metal plates are fixed a 70 mm wide strip of mortar must be applied on both sides of the joint. If plaster is thicker than 15 mm, compensation must be made for this in the initial mortar layer placed under the side plates. The profile must be fixed rigidly to the substrate and must on no account be allowed to have free movement, otherwise cracks in the plaster will occur. Fixings must be made

 

on both sides ofthe perforated side plates. When flexible insert is longer

than 8/10 m, it is necessary to fix this, to avoid sliding.
