THE STORY BEHIND SUSTAINABLE INSULATION Sustainability aims to strike a balance between economic and social development and environmental protection.

Insulation is a key tool to make buildings sustainable.

CONSUMER CONFUSION A lot of claims are being made with regards to how ‘green’ insulation products are.

Insulation is not a stand-alone product, like for example a washing machine. Insulation is used in buildings/building components in combination with other materials.

PU INSULATION IS THINNER AND SAVES VALUABLE SPACE

WHEN TAKING ALL ASPECTS INTO ACCOUNT, PU INSULATION SHOWS AN EXCELLENT ENVIRONMENTAL PERFORMANCE Different materials have different thermal insulation capacities, densities and installation requirements.

PU may have a higher impact at product level but reduces ancillary material use and has a similar impact as natural insulants when assessed at the building (element) level.

HOW TO INFORM PROFESSIONALS?

AND CONSUMERS?

BEYOND FACTORY GATES

Multi-indicator building ratings based on EPDs allow for informed choices for LCA experts and architects.

Unfortunately, there is no satisfactory communication format today. This does however not justify claims that do not reflect real performance.

When looking for the sustainability of insulation, one has to look beyond the factory gates.

How the product performs in the built environment, how much product is needed to achieve comparable energy savings and what other savings can be achieved by saving space and weight should all be taken into account.
