is the key characteristic to ensure sustained insulation properties over time.

The other advantages of the PU boards are that they are thin, resulting in more internal living space, and they are versatile enough to be used both in the construction of new buildings and in retrofits.

Elastopor H also has a long life cycle, retaining its properties for 10-50 years, and is recyclable by various methods including glycolysis, adhesive pressing, pulverisation and incineration to generate heat. Unlike the others, BASF Polyurethanes also has the technology to increase fire-retarding performance of rigid foam without causing it to lose any of the other key properties. 12

Heat conduction can be reduced to an absolute minimum. Refrigerator energy consumption can be reduced by roughly 30 percent compared to traditional forms of insulation. • Insulation thickness can also be reduced with Elastocool Plus®. This leaves more useable space within the fridge. • Consisting exclusively of organic material, recycling of VIPs is no problem at all.
