Why to opt for bitumen roofing?


ONDULINE uses Bitumen as roofing material because of its excellent waterproofing performance and is an expert in bitume roofing solutions. Why bitumen?
The bitumen is naturally waterproof and insoluble in water which is why it has been used since the beginning of human civilization to protect the roofs and boats from water.
The bitumen is a thermoplastic material, which means that it is liquid at high temperature (>150°C) and solid at ambient temperature. It is an interesting property to process and can be used for industrial purposes, as well as on roads or roofs. Bitumen is also a viscoelastic material, which means that it has the capacity to absorb sound by transforming vibration into heat.

That’s why bitumen is also used as a heavy mass around car engines and in washing machines… as a sound proof material.


Different applications of bitumen roofing


  • For low pitched roofs, flat roofs and foundations, Onduline offers bitumen membranes – called BITULINE

BITULINE membranes can be installed on pitched – even low pitched roofs and on flat roofs to create green roofs for example 
The installation is made by a professional: the membranes are torch on together by fusion welding. Once applied, this welding ensures that your roof is protected from leaking for many years.
Depending on your needs and your project, we have a range of high-performance membranes for the roofing with coloured finishes, specific membranes for green roofs or for tropical areas.
