Wall sleeve installation
NOTICE: If the slope of the core drill hole is too low, condensation can run towards the interior wall. Ensure a slope of 1...2 % towards the exterior wall so that any condensation which collects can drip off to the outside.
Exercise CAUTION when handling construction foam. Wear protective gloves and goggles.

- Drill a core drill hole in the wall.
- Shorten the wall sleeve to the wall thickness. Select the length of the wall sleeve so that it is flush with the plaster on both sides.
- Seal the gaps between the wall sleeve and the wall all around in a permanently elastic and weather-resistant manner. Fix the wall sleeve with non-pressing or expansion-free construction foam. Cut off protruding construction foam flush with the wall.
