Legerdrain

Legerdrain

Legerdrain is a type-3 expanded polystyrene insulation panel with four rabbeted edges. Its integrated drainage grooves are ideal for rooftop terraces.

The polystyrene blocks are highly resistant to temperature variations and thaw-freeze cycles, and they are waterproof, making them an ideal choice for the insulation and drainage of green roofs.

Our wide range of panels have a compressive strength range from 207 kPa (30 psi) to 414 kPa (60 psi).
