Butylclad Rubber Waterproofing Membrane
Description

 Viking Butylclad is a rubber membrane ideal for waterproofing low-slope roofs and gutters.

Viking Butylclad comes in long narrow rolls that minimises unnecessary end-laps and off-cut waste. Viking Butylclad membranes are made of 70% butyl and 30% EPDM (ethylene propylene diene monomer)rubber; the latter providing the extra UV resistance and elongation properties over 100% butyl membranes.

Butylclad is also suitable for industrial, commercial and residential roofs, decks, balconies and parapets and is formulated to suit a wide-range of climatic conditions — ideal for both inland and coastal conditions.
