A roof over your head

With the right kind of bitumen, it’s possible to avoid expensive, complex roof renovations. Nynas is one of the leading suppliers.

The roof is the most exposed part of a building. Rain, wind, snow and ice, as well as hot sunny days, can all subject the material to extremely tough stresses. 

To prevent moisture from penetrating the structure of the roof, and also to guarantee a strong resistance to mechanical wear, builders use roofing felt, or to give it its proper name: roofing membrane. 

A roofing membrane contains limestone filler and bitumen. The proportion of bitumen is very high, 65-70%, in contrast to asphalt, where the proportion is around 5-6%. Furthermore, a relatively rigid, hard bitumen is used with especially tough demands to withstand, for example, ageing, high temperatures and fire. 

Polymers are now usually added to the bitumen used to manufacture roofing membrane. The advantage is that the polymer modification enhances the elasticity at both low and high temperatures, creates greater splice strength and also makes it possible to use softer bitumen, which improves the thermal properties.

Nynas has developed a product – Nytop 210 – that is being used by many leading roofing membrane manufacturers all over Europe in their production.
