• Fix the wall installation sleeve with a slope
of 1 – 2° to the outer wall.
►
Fix the wall sleeve on the inside and outside walls
with the mounting wedges so that it has a gradient
of 1 – 2° to the outside wall.
►
Check the inclination of the wall sleeve with a spirit
level.
1 – 2°
NOTE:
Avoid contamination of the wall
sleeve and the fastening
elements!
• Before foaming the free space between
the wall sleeve and masonry, insert the
Styrofoam disks.
• Do not remove the thread locks of the
fastening elements until the inner cover
has been fitted.
►
Insert the Styrofoam disks into the wall sleeve on
the inside and outside walls.
►
Align the two lateral mounting elements of the wall

►
Before foaming, stabilise the wall sleeve with a
suitable material so that it does not deform.
►
Foam the free space between the wall installation
sleeve and masonry all around with non-pressing
2-component installation foam.
NOTE:
Interruption of the thermal
insulation composite system.
Damage to the building substance!
• During installation, guide the wall structure
back up to the wall installation sleeve.

Mount the external closure
NOTE
Mounting on unfinished outer wall

Penetration of condensation water and/or algae accumulation around the weather
protection hood
leads to damage to the masonry/external wall and/or discolouration of the facade!
• Prior to installation of the external closure apply all sealing strips on the weather protection
hood circumferentially.
• Before installation, make a biocidal presetting/water-repellent pretreatment of the surface
weather protection hood (Please consult your planner!).
