A liner retains fill while remaining part of a wider installed system. Selection should follow the intended fill, exposure and attachment arrangement rather than a colour choice alone.
Describe fill and exposure
Identify the expected fill grading, placement method, moisture exposure and storage period before installation.
Confirm attachment and coverage
State which faces require lining, how overlaps are handled and whether replacement access is important for the site plan.
Request traceable documentation
Agree the data sheet, inspection record and batch identification needed with the shipment instead of assuming one document suits every destination.
