AURA FAST: BREATHABLE UNDERLAY
![teli_aurafast_intro_web800](https://accessorirasera.com/wp-content/uploads/2017/12/teli_aurafast_intro_web800.jpg)
Breathable underlay in multilayer polypropylene and felt
Allows excess moisture to rapidly escape
AURA FAST consists of two layers of polypropylene and a layer of felt bonded by means of an ultrasonic process without the use of additives or solvents, in total respect for the environment. The peculiarity of Aura Fast is its high condensation dispersion ability achieved thanks to a uniform distribution of the water in the dispersing layer.
The felt layer acts as a conveyor. Its intrinsic characteristics allow it to distribute the water in every part of the membrane by drawing it from areas in which it has concentrated to a greater extent and spreading it evenly in contact with the breathable film. Thus maximum efficiency in terms of water vapour transfer efficiency is obtained by taking advantage of the greatest possible area available.
Completely Made in Italy. Produced with ultrasound technology. Possesses high mechanical performance, non-slip properties and is fully recyclable.
- Available in 240 g/m2 versions.
COMPOSITION
Top layer: heavy non-woven polypropylene fabric with anti-UV and grip treatment. Abrasion and tread resistant. Absorbs mechanical stress (tensile, shearing stress).
Reinforcement: waterproof, highly breathable microporous polypropylene film with anti-UV treatment.
Felt: the felt speeds up the drying process by evenly distributing the moisture.
ULTRASONIC LAMINATION
The three layers are spot welded together to ensure greater mechanical strength and breathability.
