DELTA®-TRELA Underlayment for Metal Roof Claddings
Residence, Hagen

This residential building in Hagen, Germany, was designed with a high-end zinc roof cladding that was installed over DELTA®-TRELA to enable drainage of condensation water and backside ventilation for the zinc panels to prevent corrosion.

Around 900 m² of DELTA®-TRELA, a highly vapor permeable underlayment with integrated structural separation layer, were installed.
