Inherently, low-density
polyethylene will last indefinitely when buried in the ground and more than forty years in roofing
assemblies.
No maintenance is required after the membrane is
installed.รก Stored in a covered
warehouse, the membrane will remain usable for many years.
What are its limitations?
Temperature,
fire, long term exposure and solvents limit the effectiveness of low-density polyethylene.
Monofilaments have U.V. stabilizers that help increase resistance to long-term
exposure.
