DELTA®-TRELA Underlayment for Metal Roof CladdingsThe roof of this sport stadium in Bochum, Germany, was refurbished 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 15,000 m² of DELTA®-TRELA, a highly vapor permeable underlayment with integrated structural separation layer, were installed.
