DELTA-Trela
Brand: Delta®
DELTA®-TRELA is a vapor-permeable underlayment with structured separation and drainage - specifically designed for metal roofs and façades with metal cladding, preventing corrosion and moisture accumulation underneath panels and ensuring the longevity of your metal roof.
Features- 8 mm studded fiber mat ventilates the underside of the metal panels
- Drainage course – the 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 15 dB
- 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
