Recipe against moisture, draughts and cold

Although 85 % of all bitumen is used in road applications, there are other applications where bitumen’s properties bring value.

In these industrial applications it is used to insulate against moisture, heat, sound and vibrations among other things. Some of the applications use oxidised bitumen, which has high heat resistance.

These are properties required by Hunton Fiber for their bitumen-impregnated wood fibre panels. The company, based north of Oslo, is one of the Nordic region’s leading producers of wall panels and other wood fibre-based products for the construction industry.

The addition of Nybit I 142 in Hunton’s panels keeps the wall sealed so that moisture and draughts do not penetrate the insulation and cool down the wall. The impregnation process also makes the panels resistant to mould, rot and pests.

Nynas expertise highlighted

This year’s E&E Congress will feature presentations of a large number of technical articles, representing top-level expertise in current bitumen and asphalt technology. Experts from Nynas have contributed to several of these, in some cases as lead author. Dr Anna Steneholm, Group Specialist Toxicology, and Dr Ian Lancaster, UK Technical Manager, have also been selected to give oral presentations.

The importance of interlayer bond coat application during pavement construction

With our collective duty to ensure sustainable and environmentally responsible solutions, it is more important than ever that the road construction industry strives to get things right first time and build structures to last. That implies new structures, as well as maintenance interventions, must be effectively designed and the installation must truly reflect that design.
