Stratigraphy Details: Refurbishment with re-qualification of flat roof with transformation into extensive green roof.

An "extensive green roof" always requires thermal insulation, so if there is no thermal insulation in the existing layers, or if there is a desire to supplement insufficient insulation, the “inverted roof” system is the simplest and least costly insulation system.

Description of the layers and related product data sheets:

1. Old bitumen covering

2. Primer

INDEVER

ECOVER

3. Membrane (first layer)

FLEXTER TESTUDO SPUNBOND POLIESTERE

4. - 5. Membrane (second layer)

DEFEND ANTIRADICE POLIESTERE

6. Thermal Insulation

POLISTIRENE ESTRUSO
