ISOLINE LOW LINE Sub-Roof system for waterproofing guarantee at 10 degrees pitches.

ISOLINE® LOW LINE sub-roof systems is used as a secured waterproofing layer, under the tiled roof. This solution is a perfect waterproofing barrier against potential leaks, that may happen over time through a breach in the tiles covering.
With a corrugation height of just 24mm, ISOLINE® LOW LINE is fixed below the primary tile or slate roof covering, acting as the primary waterproofing layer of a roof, making roof tiles a secondary line of defence enabling the pitch of the roof to be much lower than the minimum as recommended by the tile manufacturer.
