Technical Specifications

  • Install waterproofing safety mantle made oa bituminous membrane 4 mm thick, reinforced with polyester fibre, folded up on the parameters and soldered to eventual wall breaks.
  • Lay down STIFERITE's GT panel
    (alternative: STIFERITE Class S - STIFERITE GTE)
  • Separating layer and vapour barrier.
  • Lay down reinforced mesh
  • Vertical separator made of closed cells expanded polyethylene, 5-10mm thick, installed on the parameter and on the base of the elements in elevation.
  • Laying down of the cement floor slab

Instructions and Guidelines
The safety mantle helps against the rise of humidity and necessary in case of shallow groundwater. 
The function and type of vapour barrier must be evaluated relative to the internal hygrometric and ambient conditions.
Due to its’ high compression resistance, STIFERITE’S Class SH panel is available in cases of very heavy loads.

The tables indicate the suggested thickness of Stiferite’s panels based on

  • Climate Zones
  • Current legislative set limits of thermal transmittance
  • And the following composition of the structure:
