You are here: Building Insulation - Roofing - With tiles over wood laths

Technical Specifications

  • Positioning of the edge stop beam
  • Spread a breathable membrane mantle of non-woven fabric
  • Lay down STIFERITE’s Class S panels
    (alternative: STIFERITE’s GT)
  • Spread a waterproofing and breathable membrane of non-woven fabric
  • Lay down and install laths in the panels and the structure underneath
  • Lay down and install metal profiles to support the tiles
  • Lay down and install regular or clay tiles and ventilation elements (bird protector grill, ventilated ridge)

Instructions and Guidelines
Polyurethane foams are able to withstand high temperatures (+90/100°C) that accumulate on the protective element  subjected to the sunlight

The use of metal profiles to install the tiles available as an accessory of the Isoventilato system, is a valid alternative to the traditional double wood laths method

Also see: the installation procedure

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:
