Product benefits

  • Ventilated roofs
  • Strong understructure
  • Easy installation


ISOLINE is a special waterproofing sheet applied under the roof tiling.  It is fully compatible with Marseille and many other types of  tiles.

It can be used for all types of clay tiles with wooden battens. It is possible to form up absolutely watertight, perfect roofing systems which may incorporate heat insulation on option, together with ISOLINE sheets.



With its high quality, ISOLINE system meets the international standards related to environment and sustainability.







An air space of 90 cm²/m resides beneath the ISOLINE gutters. This space helps to discharge the vapor inside the building before it condenses, creating an air circulation over the heat insulation materials. Additionally, the flow of air created among the roof tiles and ISOLINE allows rapid drying of roof tiles.





Aesthetic roof

Roof tiles are laid into the special grooves provided on the ISOLINE. By this technique, not only roof tiles are prevented from surging with one another but also the need for conventional rope tensioning technique, used in normal course of procedure to ensure a level and flat roofing, is completely eliminated. An aesthetically appealing look is thereby obtained with easy and fast workmanship.





70% savings   

For standard Marseille type tiles, it is considered enough to have flat battens laid at 34 cm distance. Compared with full deck roofing systems this application technique availed by the highly strong structure of ISOLINE provides up to 70 % savings from wood battens used for roof cover

ing, while ensuring a significant reduction in the overall costs of roofing. And a spaced construction ensures a comfortable breathing for wood elements.






ISOLINE is the perfect and outstanding waterproofing solution for all types of clay tiles.





ISOLINE has a special design that is compatible with many tiles and makes you save money on the infrastructure cost since wooden battens are laid instead of covering the whole roof with OSB.





ISOLINE is a system which makes possible to apply tiles on a large roofing area.





ISOLINE is an ideal waterproofing system for historical buildings covered usually with tiles.





With ISOLINE, application gets quite easy for refections of all types of constructions.

ISOLINE is easy to master. For a complete overview of the installation, please download our documentation.



The tiles in the ISOLINE system can be fastened with a copper wire to be extended and encircled around the heads of the nails fixed  at every  5 corrugations. It is also possible to use ISOLINE hooks in fitting the tiles. The hook should especially be used at the first 2 rows of the eaves and sides of gable end, as it prevents the tiles from dislodging due to strong winds. They are also effective against slipping at steep angles when fitted behind the tiles.





ISOLINE system is fixed onto wooden roofs through galvanized steel Onduline nails with plastic washers. With nails developed specially for applications on reinforced concrete substructures, it is possible to carry out the entire application without using any wood. Concrete nais designed to get fixed in the nail hole opened with a drill ensures high durability of the cover against even the harhest winds. There are both wood and concrete nails with various sizes for fixing them together with heat insulation sheets.
