Description
 
Looking for a layer of protection underneath a pitched metal roof? Look no further than Dorken's DELTA®-TRELA, now available at Spycor Building Products.

DELTA®-TRELA is specially designed for pitched metal roofs, whether they are ventilated or non-ventilated. DELTA®-TRELA metal roof underlayment promises the ultimate level of protection. This waterproof material is resistant against tears and scuffs, and it is water vapor permeable. It provides air circulation underneath the roof panels and superior drainage that channels moisture.

Why Do You Need Protection for Metal Roofs?

When it comes to moisture management, the challenge of metal roofs and metal cladding is that they're not completely sealed to the roof's deck or sheathing. Because of this, moisture can collect under the metal. If this moisture accumulates, it can damage the roof's substructure, and it can also corrode the metal, shortening both the lifespan on the metal roof and the substructure underneath it.

The Advantages of DELTA-TRELA Underlayment

DELTA-TRELA underlayment is vapor permeable, designed for optimal structured separation and superior drainage. It's made from studded fiber mat that's thermally bonded to watertight fabric that allows vapor to permeate. DELTA ®TRELA's special design allows for ventilation under metal panels while it wicks any moisture to the outside, away from the roof's substructure. It keeps everything airtight while allowing moisture to escape. As added advantages, DELTA®-TRELA by Cosella Dorken also provides a non-slip surface for easy installation as well as it reduces rain and hail noise up to 15 decibels.

Material

With its highly vapor permeable membrane (3-layer made of tear-resistant, diffusive, PP spun non-woven fabric / film combination) combined with a polypropylene randomly oriented fiber mat with studded structure, DELTA ®TRELA is the industry leader in roof underlayment for metal roofs.

Characteristics

The 8mm high randomly oriented studded fiber mat ensures a permanent swirling of air around the underside of the roof panels. As a drainage course, the studded structure reliably channels the moisture away from the rafters and sheathing that can get water damaged when not using a high-quality metal roof underlayment like DELTA®-TRELA. By virtue of how the studs are arranged, DELTA-TRELA can be used in any direction around the formation of detail elements, so no matter what angle your roof is pitched at, DELTA®-TRELA will work for you. The metallic rattling noise of rain or hail will also be deadened to as low as 8dB. Due to the membrane's high vapor permeability residual moisture from the rafters and sheathing is able to migrate to the outside.

Application

Lay DELTA®-TRELA parallel to the eaves of the roof. Have the studded structure face up. Overlap the next membrane in clapboard style, thus ensuring that water runs off towards the eaves. The studded texture of the metal roofing underlayment is non-slip and the laid area is rainproof.

5 of 5 But why? January 23, 2020
Reviewer: Guy from Barstow, CA United States  
Product is definitely high quality, and seems like will solve all the problems I was worried about with this roof.  Installation couldn’t be easier, but for one minor detail- why are the included nails affixed to the inside of the roll?  This makes no sense!  Having the fasteners inaccessible was my greatest difficulty on this installation.
