Our accreditations
Our Accreditations

We are striving to develop and bring to market products and solutions that will be vital in supporting the construction sector, to deliver a low energy and sustainable built environment. We are amongst the pioneers in product sustainability performance information, with more information than ever available about our products.

What’s more, we have developed tools to help the market see how our products contribute to sustainable buildings. Through cooperation with our supplier, we are also making our supply chain more responsible and resource efficient. We also give clear guidance on the handling and comfort of our products.

We are working hard to help the building chain get the most out of the saving potential of insulation in practice, not just in theory.
