The standard inaccessible multi-purpose and multi-support roofing system
Derbigum SP FR is the ideal waterproofing membrane for renovation and new construction of flat roofs that are inaccessible without additional protection, even in single-layer construction. It requires little maintenance for lasting peace of mind. Of course, its application system is ATG certified.
Perfect UV resistance without protection
Derbigum SP FR is composed of the best APP bitumen and two reinforcements decentralised to the surface – glass fiber and unwoven polyester fleece. Derbigum SP FR is perfectly resistant to UV rays without additional protection, but also to wind forces, thermal shocks, “halogen free” fire and also offers perfect dimensional stability. The roof, although technically considered inaccessible, remains walkable without risk of perforation or tearing.
Durable: 50 years, proven!
The BBA, British Bureau of Agrément, an independent British institute, has carried out surveys on 50- year-old roofs, such as on the highly exposed ArcelorMittal site in Dunkirk . The BBA report attests that after 50 years of good and loyal service, the “durability of Derbigum SP FR membranes used in accordance … can reach at least 50 years. »
Derbigum SP FR can even double its service life thanks to a new Derbigum coating on top of the old waterproofing. A very economical long-term solution.
At the end of its life cycle, Derbigum SP FR is 100% recyclable for a more circular economy.
