184 Alfa Metal Roof Separation Layer
3-dimensional ventilation layer made of tangled polypropylene spirals. The 9 mm high mat guarantees permanent ventilation under the metal roof.
Separating Layer for Metal Roofs
Alfa Metal Roof Separation Layer is used in ventilated and unventilated pitched roofs as a separating layer to prevent corrosion of metal roofs. The 9 mm high polypropylene mesh allows air to flow under the metal roof. Due to its knotted structure, it is also a drainage layer which canalises moisture reliably and lets it escape.
Because of its special structure, the Metal Roof Separation Layer can be installed regardless of orientation. It also reduces noise caused by rain or hail.
- Separation layer made of randomly intertwined PP threads
- 350 g/m²
