Designed to be used with all roof tiles, new or existing; ISOLINE® LOW LINE, Onduline’s lightweight bituminous sub-roof, is fixed below the primary tile or slate roof covering, acting as the main waterproofing layer of a roof, making roof tiles a secondary line of defence.
The ISOLINE® LOW LINE sub-roof is ideal for:
- Low pitch roofs: by integrating the ISOLINE® sub-roof, all roof tiles can go down to 10 degrees
- Heritage sites: the existing roof tiles can be re-used, as the ISOLINE® sub-roof becomes the main waterproofing element
- Extra guarantee / protection: the ISOLINE® sub roof is forgiving, meaning any issues with the roof tiles are taken care of by the ‘roof beneath the tiled roof’
WHY USE ISOLINE® LOW LINE?
