Swisrail EWI: NHBC  

 

  • An NHBC compliant, fully warranted system with an effective life in excess of 30 years
  • The Swisrail system incorporates a drained cavity via a support frame to give full NHBC compliance. A cavity is provided to prevent moisture penetrating to the underlying structure
  • The system is fully weather resistant whilst remaining vapour permeable and allows the fabric of the building to act as a heat store, increasing thermal efficiency
  • Swisrail eliminates cold bridging, condensation and mould growth and protects the structural fabric of the building and is resistant to impact damage. It is rated Class 0 for surface spread of flame and contributes to sound reduction within the external wall construction
