Derbigum Olivine Membrane

Key Features & Applications

• Derbigum Olivine membranes, have a naturally occurring mineral upper layer that neutralises CO2 via an irreversible chemical reaction when it comes into contact with rainfall 
• The Olivine grains decrease in size with each reaction, however the grains are large enough to last 30 years before having completely reacted
• Derbigum Olivine membranes are 100% recyclable
• BBA approved with fully warranted systems available with a life expectancy in excess of 40 years
• Suitable for flame-free and cold application to warm roofs with metal, concrete or plywood decks and inverted roofs with concrete decks
• The high melt point ensures membrane stability in the hottest weather whilst the polyester/glass fibre reinforcement provides high tensile strength
• Manufactured in accordance with ISO 9001:2008 and ISO 14001:2004
