GreeN rOOFING Recently, green roofing systems have been attracting increasing interest because of the significant contribution they can make to environmental compensation, particularly in areas where construction makes permanent changes in the landscape. Green roofs help reduce stormwater runoff because of these systems’ ability to retain and gradually release rain water. With this publication, IMPER ITALIA presents a number of green roofing approaches based on the latest generation TPO/FPA thermoplastic olefin and flexible polypropylene waterproofing membranes in the RUBBERFUSE Division’s...

Filter layer Leveling layer he filter layer prevents fine particles from the growing medium from reaching the drainage layer and clogging it over time. Our filter layer consists of 100% isotactic polypropylene nonwoven needled and hot-calendered DRENO FELT PP 200 geotextile. Our leveling layer and substrate for the subsequent sealing layer consists of 100% isotactic polypropylene nonwoven needled and hot-calendered DRENO FELT PP 200 geotextile. Protection and drainage layer Protection and drainage functions can be performed by a single preformed panel or by several different products...
