A non-walkable roof system with combined base made of profiled steel sheeting and sheet-backing of plate materials with a roof cladding of polymer membrane, without additional insulation.
  • Fast assembly
  • A cost-effective system
  • High endurance of the foundation layer


A roof system used on profile-shaped flooring without additional insulation. To create an even supporting surface where the membrane is to be laid, a sheet-backing coat is used.

The sheet-backing coat is made of cement-asbestos boards or cement bonded particle board, at least 12 mm thick, laid in two layers with spacing of seams and the fastening of one layer to the other, which provides the system with advanced fire resistance.

The roof cladding is made of LOGICROOF polymer membrane, which has a combustibility group rating of G1/G2, which is why the TN-ROOF Combi system can be used on roofs with a large area.

The system has fire hazard class K0 (15) according to GOST 30403-2012, which makes it possible to use it for atticless roofs in buildings of II-V degree of fire resistance with any class of building fire hazard. The system also has an RE 15 fire resistance limit according to Federal Law No. 123.

Area of application:

The TN-ROOF Combi system is successfully used for the construction of cold roofs on public and industrial buildings with high loads arising during the servicing of the roof (including snow removal), as well as during inspections and maintenance of equipment placed on the roof. TN-ROOF Combi can be installed quickly and easily due to the large width and length of the polymer membrane rolls, which is economically justified at construction sites of a large area.
