Areas of application
Isola Isokraft is a strong bitumen-based type of underlay that can be exposed for long periods of time (even during the winter), thus enabling roofing work to be completed during more favourable seasons. Suitable for all types of sloping roof constructions with a supporting sub-roof with a minimum pitch of 6º.
Isola Isokraft is particularly suitable for use as underlay for turf roofs and Isola Takshingel (where required).
Other areas of application: slate roofs, strip roofs, sheet roofs and tiles.
Isola Isokraft consists of a polyester core with reinforced netting and self-adhesive edges designed to guarantee adhesion at temperatures as low as 3ºC. The core is coated on both sides with SBS polymer bitumen and the surface is coated with silane sand. This back of the underlay is covered with smooth foil that prevents the coating from sticking to the sub-roof.
