Derbigum has a life span of 45 years.
Other waterproof solutions have a life span of 10 to 20 years, then they have to be replaced and a new investment has to be done in the renewal of your roof. Furthermore they are less resistant and have therefore higher costs for maintenance and repairs.
Independent studies have shown that after 45 years, a new layer of Derbigum is enough to extend the life span of your roof with another 45 years.
The strict energy checks during the production process, the use of recycled materials and the life cycle analysis make that Derbigum membranes are produced with respect for the environment. In 8 years time Derbigum hasreduced its CO2-consumption during the production process with 70%.
