Ondulit metal sheets are particularly successful in hostile environments such as industrial spaces and exhibit high resistance in corrosive atmospheres like coastal and urban areas. We have tested their performance after 4,000 hours of exposure to salt spray, which is why we can guarantee their durability for 30 years.
Ondulit sheets provide protection from external heat. Just a few millimeters in thickness offer as much protection as a sandwich panel. Thanks to the patented formula they are made with, Ondulit sheets create cool environments inside buildings.
Ondulit roofing sheets are made using multilayer technology: 3 layers of metal and 2 layers of plastic composite, welded together to create unique products that last for decades.
1. Upper aluminum layer
Anticorrosive and reflects the sun’s rays
2. Protective and soundproofing compound
Anticorrosive and ensures that the metal sheet is soundproof
3. Galvanized steel
Structural and provides mechanical strength
4. Primer
Anticorrosive and protects the steel
5. Lower aluminum layer
Low emissivity inwards and is a gas and vapour barrier
