Instructions for proper RAL installation
NOTE
Interruption of the thermal insulation composite system.
Damage to the building structure.

Observe the regulations in the RAL installation guidelines!
Wall sleeves must be inserted in wall openings, aligned with a gap and finished flush to the
interior wall. Modern walls consist of multiple vertical layers which are penetrated during the
creation of the wall opening. Replace this construction as far as the wall sleeve. A similar
situation exists during the installation of windows and doors; their installation must be carried
out according to RAL
1)
and is regulated normatively. Apply this procedure also for inVENTer
®
ventilation devices. In addition to the supporting and insulating properties of the walls, there are
also defined barrier layers:
Water vapour barrier
The water vapour barrier is usually in the interior wall and prevents the penetration of water va-
pour from the living space into the wall. This water vapour can condense to water at cold spots
in the wall and thus lead to thermal bridges.
Rain barrier
The rain barrier is waterproof and resists rainwater up to a certain pressure. This barrier is lo-
cated on the outside and is permeable to water vapour in order to bring the moisture out of the
wall and keep the wall sufficiently dry for a long time.
Wind barrier
Multilayered walls often have special windproof layers that are created
using film systems. Frequently, water vapour barriers also perform this function.
Expanding waterstops
Expanding waterstops complement the barrier system by flexibly filling gaps and joints between
components and masonry. They often also serve locally as rain barriers and water vapour bar-
riers.
Adhesives
Adhesives create a long-term bond between various foils.
If present, rebuild these wall layers as far as the wall sleeve. Various materials, systems and
additives are available for this purpose. Only use tested and approved materials and read the
manufacturer's working instructions thoroughly prior to use.
