Epiclad (EPDM) Rubber Waterproofing Membrane
Description

Viking Epiclad is a ‘no nonsense’ membrane made from 100% EPDM (ethylene propylene diene monomer) rubber, with over 25-years of proven performance in New Zealand.

Viking Epiclad has excellent elasticity, tensile and elongation properties and is virtually indestructible by UV, ozone and weathering. The wide sheets mean less joins, minimal installation time and optimal waterproofing capabilities. Unlike other membrane types, Epiclad membrane is arguably the industry’s best at forgiving a timber building substrate flex and movement, without splitting; especially during changing seasons.

Key Features
  • Water potability certified
  • UV resistant
  • Formulated to suit a wide range of climatic conditions
  • Impervious to heat ageing
  • Elongation breaking point
  • Pliable material
  • Can be painted with approved paint systems
  • Wide rolls (up to 6.0m wide) — fewer joins
  • Installed only by Viking Licensed Applicators
  • 20-year product warranty
  • BRANZ Appraised
