Associated Lead Mills

Needle-punched, non-woven geotextile polyester materials in two unit weights – 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.


  • Reduce drag arising from thermal movement of lead sheet over substrate.
  • Assist in the protection of lead against condensation corrosion, or chemical attack from stone, concrete or timber.
  • Protect lead from damage due to any uneven nature of substrate and provide support against downward pressure.
