B_Durability

Ondulit roofing is resistant to corrosion

Multilayer technology is particularly successful in hostile locations, such as industrial spaces, and it is very resistant in corrosive environments, such as marine and urban areas. Take a look at its performance after 4,000 hours of salt spray.

Acoustic comfort

Ondulit roofing is silent

Ondulit products absorb the impact of rain and hail, thereby avoiding the rumbling effect, typical of metal roofs. Listen to the audio of the indoor and outdoor spaces. Do you like the acoustic comfort provided by our products?

Thermal comfort

Ondulit roofing is cool

In a summer climate, the multilayer technology, which is just over 2 mm thick, guarantees the same thermal insulation as a 40 mm panel.
Take a look at the comparison between the Ondulit multilayer sheet, a common pre-painted metal sheet and a sandwich panel, all subjected to the same irradiation.

Multilayer technology is suitable for environments with any kind of climate

Multilayer technology is suitable for environments with any kind of climate

Characteristics

Mechanical strength

The steel core and the special multilayer processing give Ondulit roofing high mechanical strength. Odulit roofs are resistant to loads and therefore also ideal in areas that are subject to strong winds and hurricanes.

Characteristics

Thermal expansion

Ondulit roofs undergo limited thermal expansion – precisely that of steel. Furthermore, thanks to the ability of the multilayer to repel direct solar radiation, the roofs undergo limited overheating. This unique quality makes our products suitable for areas with strong radiation or with considerable temperature variation.

Characteristics

Photovoltaic

Ondulit multilayer roofing is particularly suitable for accomodating photovoltaic systems, thanks to its durability, robustness and heat reflection. This is why the Easy-fix line was created. It is a system especially designed to allow solid anchoring of any photovoltaic module without compromising the impermeability of the roof.

Characteristics

Sustainability

Multilayer technology is at the forefront in energy saving and in contrasting the phenomenon of heat islands.
Our products have a long service life, with a positive eco-balance and an advantageous life cycle cost. At the end of their life they can be subjected to selective treatment and the recyclable raw materials can be recovered.
