POLYMANT is a safe, practical and, above all, cost-effective solution to the problem of rendering asbestos cement in existing buildings completely harmless. POLYMANT is an insulation/waterproofing system produced using a hot lamination process to bond together a 2 mm-thick plastomeric membrane - with a reinforced fibre glass mat carrier - and a pre-shaped rigid expanded polystyrene panel rebated on both sides, featuring varying densities and characteristics in terms of both thermal and fire performance.
