Insulation Diagram of the Wall Lead-through
Installation instructions
1. Create a core hole in the outer wall (maximum wall
thickness 480 mm) with a diameter of at least 125
mm.
Keep an eye out for possible supply lines in this
area!
2. Insert the telescope pipe in the wall lead-through that
you created so that the outer pipe (100 mm diameter)
is on the inner side of the wall.
To prevent cold bridges, insulate the telescope pipe
with a suitable insulation material..
3. Place bricks around the telescope pipe in the core
hole so that it is aligned with both sides of the wall.
