EFIGREEN® ACIER is intended to new flat roofs or renovation: Non-accessible, ballasted technical flat roofs, including aerial work platform runways accessible to pedestrian traffic and including surfaces protected by tiles on pedestals, roof gardens and green flat roofs, in plain and mountain climates.
- excellent dimensional stability,
- maintains insulation performance over time,
- in the event of occasional or accidental traffic, its high mechanical resistance reduces the risk of compaction of the insulation and damage to the waterproofing layer.
EFIGREEN® ACIER is a roof insulation panel for steel deck including trough width > 70 mm and < 200 mm, under self-protected waterproofing mechanically fastened or loosely laid under heavy protection (gravels, slabs with adjustable pads or screed). It is also suitable for green roofs.
