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. By virtue of how the studs are arranged, DELTA-TRELA can be used in any direction around the formation of detail elements. The rattling noise of rain or hail is 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.
Lay DELTA-TRELA parallel to the eaves. The studded structure is to face up. Overlap the next membrane in clapboard style, thus ensuring that water runs off towards the eaves. The studded texture is non-slip, the laid area is rainproof.
