Description

A roll of honeycomb-structured copper with an underside fully coated in butyl. Highly conformable, it allows three-dimensional laying that keeps contact with the substrate at every point, with no shrinkage, on broken relief. The strip seals the junctions between a roof in small elements and penetrations: walls, chimney stacks, roof windows, dormers. Laid over the ridge, it serves a second purpose as a moss treatment, both preventive and curative: rainwater takes up copper oxide on contact with the surface and then spreads it down the slope, the honeycomb relief improving water retention and therefore the effectiveness of the reaction. The quantity of ions washed off stays low, which keeps it possible to use collected water for watering. Width 300 mm, 5-metre rolls, natural copper with a quick patina. Cartons of four rolls.
