SELF-ADHESIVE SLATED BITUMINOUS MEMBRANE
BYTUM SLATE 3500
BYTUM SLATE 3500 is the reinforced bituminous membrane that ensures effective waterproofing of timber structures and, thanks to its slated surface, it ensures permanent stability to UV rays.
It consists of distilled bitumen with elastoplastic polymers and a slate coating, and is designed for application on the external side of the roof.
BYTUM SLATE 3500, EFFECTIVE WATERPROOFING AND PERMANENT UV STABILITY
BYTUM SLATE 3500 can be used for flat roofs as the final visible layer in combination with the self-adhesive and self-sealing sheath, BYTUM BASE 2500, for optimal waterproofing.
Can be used as an underlay also for low-pitched roofs. Guaranteed flexibility and workability even at low temperatures ensure easy installation.
