Guidelines and warnings
Green roofs offer significant advantages in terms of: aesthetic enhancement, effective thermal and acoustic insulation, reduced thermal stress on the waterproofing membrane, rainwater retention, mitigation of the urban heat island effect, and improved air quality.
STIFERITE panels are compatible with this roofing system and help to enhance its performance.
For the correct installation of green roofs, please refer to the guidelines set out in the UNI 11235 standard.
STIFERITE panels have an elastic compressive strength exceeding 5,000 kg/m².
