ONDULINE DURO SX 35 is made from the same durable and eco-friendly material as all of Onduline’s light weight roofing sheets and tiles. The DURO SX 35 bitumen sheets have a trapezoidal profile and a material thickness of 3.5 mm.

As with all the ranges of Onduline’s bituminous corrugated roof sheets and tiles, ONDULINE DURO SX 35 is made of bitumen, recycled cellulose fibres, thermosetting resin and natural pigments. The homogeneous base sheet is composed of cellulose fibres, pre-pigmented with resin and natural pigments for the colouring, then impregnated with bitumen asphalt under pressure and heat. The sheets and tiles are manufactured in a wide variety of sizes and colours. This process also helps to give the roof sheets their vibrant long lasting colour.

The DURO SX 35 bitumen sheets comply with the EN 534 category S and have excellent stability and durability.
