Wall and ceiling penetrations in Vreden sealed audit-ready, installed to approval, tracked in penetration plans for the consultant's sign-off.
An F90-rated wall in Vreden loses its function the instant a cable, pipe or duct passes through it unsealed. Only the approved penetration seal restores that fire resistance — and only if the system used matches the cable density.
The system depends on opening size, occupancy density and wall type.
