Why Should I Consider Derbigum Membranes? Derbigum membranes offer a number of key benefits and superior performance characteristics to architects, specifiers and contractors. 30-35 Years Life Expectancy Examinations on roof constructions with a Derbigum upper layer were carried out by BDA Dakadvies, on roofs aged between 10 and 27 years old. The assessors said ‘the quality of these old Derbigum roofs is still such that the remaining lifespan will still be several years. This means that the life expectancy can be adjusted from 30 to 35 years.’ In the Derbigum BBA Certificate 86/1593C, the BBA...
