DURO SX 35 Onduline, a ribbed bitumen roofing sheet with a 20-year guarantee!
In residential settings, for garden chalets, garages, carports or outbuildings, as well as for agricultural buildings, which already use bitumen products, structures must be covered with quality materials that withstand bad weather, and within reasonable budgets.

To offer them a roofing solution that is as durable as it is easy to install, ONDULINE, the specialist in lightweight roofing and underroofing systems, is launching DURO SX 35, a particularly resistant ribbed bitumen sheet with a 20-year guarantee. The DURO SX 35 sheet is a bitumen sheet reinforced with cellulose fibres combined with a resin. Its thickness of 3,5 mm gives it good rigidity and great strength, which allows the manufacturer to guarantee it for 20 years. Leaks and other infiltrations are prevented, so structures are protected for a long time. The DURO SX 35 sheet is the ideal solution for anyone looking for a reliable, durable and easy-to-install roofing system. Its double overlap guide technology makes it easy to align the sheets during installation and ensures the watertightness of the whole.

Lightweight, with a weight of 5,9 kg for a size of 200 cm by 82 cm, and flexible, the sheet is very easy to roll up, to pass through tight spaces, and to handle on site to ensure the edges overlap properly and thus provide good watertightness.

An ONDULINE roofing sheet with perfect finishes


To ensure a neat roof finish, ONDULINE has developed matching verge pieces and ridge caps. These are offered in the same material and the same colours as the sheets, and provide a uniform and harmonious appearance. The verge pieces developed by ONDULINE allow for an adjustment of 5 cm between the sheets and the roof. As for fixing, the choice is up to the installer depending on the quality of the substrate. ONDULINE offers 65 mm nails or 60 mm screws fitted with their sealing washer. ONDULINE universal screws are the same for all ONDULINE ranges.

Different colours available for ONDULINE DURO SX 35 sheets


With ONDULINE DURO SX 35 sheets, the new roof will blend harmoniously into its surroundings. The manufacturer offers the sheet in a choice of 4 colours: intense red, classic red, anthracite grey or green.

An environmentally friendly roofing sheet


Natural pigments, developed by ONDULINE's research and development department, are used to colour the DURO SX 35 sheet. Made of recycled fibres, the materials of this sheet are free of asbestos and ferrous metals, which guarantees that it poses no health risk. With a positive carbon balance of 4066g CO2/m2, the lowest in its category, DURO SX 35, like all ONDULINE products, is environmentally friendly.
