At ROCKWOOL, we’re dedicated to enriching modern living. We strive to
increase our positive impact on people and society by maximising our positive
product impact and minimising our operational footprint. We recognise that
operating with integrity and as a responsible business is equally important and
underpins everything we do.

As governments and societies continue to grapple with the COVID-19 pandemic,
greening the economic recovery takes on even greater significance. We’ve
just released our Sustainability Report 2020 which details the contribution our
products make toward this goal, including updates on operational improvements
and our progress on supporting the UN Sustainable Development Goals. We’re
happy to say that all ROCKWOOL Group products have been classified as having
a positive impact on the UN Sustainable Development Goals – and we’ve met or
exceeded two of our six sustainability targets ahead of time.

To celebrate, we’ve collected 10 interesting case studies – each with a
sustainability angle – from all over the world to inspire your next building project.

It was in 2017 that Bryan Baeumler discovered the
former ‘Emerald Beach Club’, while on vacation with
his wife. Located idyllically on the beach-front of the
largest and least commercial of the Bahamas islands,
St. Andros, Baeumler could see incredible potential in
the space. Although it had been closed and derelict
for eight years, he was completely captivated by the
ruined resort – to the point that he decided to invest
everything he had into revitalising the neglected
buildings with a goal of transforming them into
the ultimate luxury resort. Sounds like the plot of a
spell-binding television show? That’s exactly what
it became. Not only is Baeumler a talented builder
himself, he is also the face of all things DIY and

6,000 litres of water almost destroyed the building. The
water alone used to quench the fire could fill six stand-

the roof and interior were completely destroyed.

The investigation carried out by the fire department
in the aftermath showed that the trigger occurred
during work on the historical facade when a painter
tried to remove acrylic resin paint using a Bunsen
burner. The existing roof insulation ignited as a result.
For Dewies, fire safety became a top priority when
considering the resulting renovation of the historic roof
and creation of a new roof structure.

Stone wool – naturally fire resistant
Insulating a roof is an effective way to minimise heat
loss and reduce heating bills and is important to con-
sider as a major aspect of any roof renovation project.

Non-combustible stone wool was the obvious insu-
lation choice for Dewies. Supported by Schade and
his team, they decided on a ROCKWOOL insulation
solution for pitched roofs that offered heat, noise and –
most importantly – fire protection.

The geometry of the roof was a challenge when it came
to installing the modern insulation, as the large dormer
windows at the front and back created many ridges
and throats. This made a lot of detailed work necessary,      After the renovation, the Hirsch pharmacy reopened for
