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.
