Built-up Roofing (BUR) Built-up roofing, or BUR roofing, is used primarily for flat roofs. It''s made from multiple layers of asphalt, ply sheets, aggregate, and other materials. BUR roofing protects from ultraviolet damage and has great waterproofing qualities. The average cost of a BUR roofing system for flat roofs is $3.42–$4.90 per ...

Indium demand is expected to rise to 1,730 tonnes by 2050—largely because of demand from solar energy. Similarly, vanadium may also see a large spike in demand due to the growing need for energy storage technologies. On the other end of the spectrum, iron and aluminum have the largest demand figures in absolute terms.
