TN-ROOF Inverse

A non-operational inversion roof system on a concrete base with a bitumen-polymer roofing carpet.

  1. Bitumen primer TECHNONICOL No. 01
  2. Technoelast EPP
  3. Needle-punched geotextileTechnoNICOL 300 g / m2
  4. Extruded polystyrene foam TECHNONICOL CARBONPROF 300
  5. PLANTERgeo drainage membrane
  6. Ballast (pebble or granite crushed stone, fraction 20-40mm)
  7. Sloping layer of expanded clay gravel
  8. Reinforced cement-sand screed with a thickness of at least 50mm
Description

In this inversion system, the bitumen-polymer material Technoelast EPP, laid in two layers, plays the role of vapor and waterproofing.

Only extruded polystyrene foam is used as thermal insulation, which has low water absorption and fully retains its thermal insulation properties under conditions of constant presence of water.

To create a drainage gap and quick drainage of water, a layer of needle-punched geotextile is laid between the extruded polystyrene foam and the bitumen-polymer material.

In the TN-ROOF Inverse system, the entire roofing cake is held by its own weight of the ballast.

Application area

The TN-ROOF Inverse system is used for the installation of ballast unexploited roofs according to the inversion scheme on residential and public buildings and structures. Such a system is convenient to use for roofing in areas with constantly low ambient temperatures, as well as on buildings and structures with a multi-level roof.

Main advantages
  • High protection of the roofing carpet from mechanical damage and exposure to ultraviolet radiation
  • Durability of the roofing system
