ISOLINE LOW LINE: The sub-roof system for roof pitches as low as 10°
BRE and BBA tested waterproofing system for any roof tile down to 10 degrees.
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.

GUARANTEED WATERPROOFING
Designed to be used with all roof tiles, new or existing; ISOLINE® LOW LINE, lightweight bituminous sub-roof 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.

Fast installation

Increased ventilation
Due to the corrugations, ISOLINE® LOW LINE allows increased ventilation and airflow both above and below the
sheet and tile battens positioned above the corrugations allow moisture to drain to the eaves which, with the enhanced ventilation, maintains excellent moisture control within the cavity.
