Cavity barriers are designed to restrict the movement of fire and smoke through concealed cavities.
Their position and construction depend on the external wall system.
They can interact with:
Problems can include:
Because cavity barriers are usually concealed, investigation may require targeted opening-up.
Our dedicated survey team can undertake intrusive façade investigation to establish the existing wall construction and investigate concealed components.
Where defective cavity barriers are identified, remediation may involve:
See our Cavity Barrier Remediation Services.
Cavity barrier defects can form part of a wider external wall problem.
A remediation project may therefore involve:
Investigation → Assessment → Strategy → Design → Cavity Barrier Remediation → External Wall Remediation
Where cladding is removed, previously concealed cavity barriers may become accessible for inspection.
This can provide an opportunity to address associated defects as part of a coordinated remediation programme.
If an existing survey, fire assessment or external wall investigation has identified defective cavity barriers, Trident Facades can discuss the required remediation scope.
