MAGNUM is a bitumen-polymer membrane for waterproofing applications.
The BRAI long experience and research have leads to the creation of the MAGNUM APP compound, combined with the last generation of reinforcement in non-woven po- lyester stabilised with glass fibres threads.
The result is a versatile membrane suitable for hot climate conditions with excellent shape and dimensional stability and mechanical properties in this class of pre-fabricated waterproofing torch-on membranes for the most popular applications with the best ratio cost-performances.
MAGNUM membranes can be supplied with top finish in PE film or sand, self-protecting natural or coloured slate chips.
