Needle-punched, non-woven geotextile polyester materials in two unit weights.
For installation between lead sheet and substrate.
Needle-punched, non-woven geotextile polyester materials in unit weights of 200 and 220 g/m². Suitable for uneven surfaces, e.g. traditional timber boards. They do not rot or cause adhesion and allow space for air flow between lead sheet and substrate.
