Low lambda products ensure better thermal performance.

The lambda value (thermal conductivity) of an insulation material is a measure of its ability to prevent the passage of heat at a particular thickness, in defined conditions.

As the lambda value decreases, the thermal performance of the material increases. With new system designs, having a product with a lower lambda value allows the designer to make use of a thinner product which will yield the same results and save time on installation and encapsulation.
