SOURCING REFERENCE for cavity foam HS1.
IMPORTANT: The cavity foam may only be use for cavity sealing at the points at which cavity sealing is present as standard!
The following repair represents the replacement of a shaped part for the cavity sealing by the use of cavity foam.
This type of cavity sealing is used at points at which shaped parts cannot be used for repairs.
This is the case when large amounts of heat occur (e.g. due to welding, soldering or tin-plating) in the direct vicinity or at the point of the standard cavity sealing.
It is not possible here to install shaped parts for the cavity sealing because of the fire risk! To replace shaped parts with cavity foam at further locations, adopt the procedure shown here and adapt it to the relevant ratios.
It must be ensured that the cavity sealing is fully completed.
NOTE: Check the accessibility for the spraying pipe of the cavity foam to the affected cavity after removing the defective parts.
