Delta Trela by Dörken is a high-performance underlayment designed for pitched metal roofs. Its structured separation layer provides ventilation and drainage, preventing moisture buildup, condensation, and corrosion beneath metal roofing. Made from durable, vapor-permeable material, Delta Trela ensures a dry, protected roof assembly while reducing noise and enhancing long-term performance. Ideal for residential and commercial applications, it delivers superior protection and durability for metal roof systems.

Product Benefits

  • 8mm studded fiber mat ventilates the underside of the metal panels
  • Drainage course – studded structure reliably channels residual moisture to the exterior
  • Vapor permeable, watertight fabric ensures airtightness and allows moisture within the roof cavity to escape via diffusion
  • Rattling noise from rain or hail is reduced by up to 15dB
  • Installed parallel to the eaves, with the studded structure facing upwards, the next section of membrane is overlapped in shingled fashion, ensuring that water is shed to the exterior
  • Burled, studded texture provides a non-slip surface during installation
  • One-step installation, faster and easier than applying an underlayment and a separation layer in independent steps, saving time and money on project schedules
  • Included with every roll is a package of 120 DELTA®-SEALING NAILS used for fastening

SHIPPING TIME

  • All Delta rolls ship for free (standard ground, see map)
  • Call: (800) 731-8420 for pricing and shipping questions.
