Rockwool’s innovative insulation enables climate action

4 min read 2 Aug 22

Rockwool is the largest maker of fire-resistant stone wool insulation for buildings. Made by spinning molten rock into wool, this material is, over its useful life, a more carbon-efficient alternative to plastic foam and glass wool insulation. The company also applies its stone wool technology to ceilings, cladding, horticulture and water management.

Why do we invest?

Rockwool is well-positioned to meet growing demand for more sustainable, energy efficient and fire-resistant buildings. Its advanced technology differentiates it from competitors. While less-costly plastic foam and glass wool alternatives dominate the market for insulation materials, the better insulation qualities of stone wool mean it can be more cost-effective in the long run. The market for new and retrofitted building insulation is vast, with particular opportunities for stone wool products in underpenetrated markets like the US and UK.

What is their impact?

Verbund is a leader in clean energy. It generates 95% of its electricity from renewable sources, and aims to achieve 100%. Having closed its last coal-fired power station in 2020, the company is adding more onshore wind and solar generation capacity. Electricity production accounts for roughly one-quarter of the world’s greenhouse gas emissions.

By generating low-cost, zero-carbon electricity from renewable sources, Verbund contributes to the achievement of UN Sustainable Development Goal 7 – affordable and clean energy for all.
