Uninsulated buildings may lose up to a quarter of their heat through attic and roof spaces1. ROCKWOOL loft insulation helps to reduce this.
Our range is made from premium stone wool, providing a cost-effective and energy-efficient solution to maintaining consistent temperatures.
Learn all about it – and discover which ROCKWOOL product is right for your new build or renovation project.
As heat normally rises, uninsulated lofts and attics are prime places where it can escape from a building. Cold air can also easily enter.
The short-term solution? Turn up the heat in the winter – and put the aircon on in the summer.
However, this wastes a lot of energy and leads to bigger heating and electric bills – as well as having a negative impact on the environment.
Installing loft insulation in the loft space, both between and over the joists, can combat this - helping keeping the heat in and the cold out.
Premium stone wool insulation helps to:
High quality ROCKWOOL stone wool can last the lifetime of a building 2 3, passing on the savings to the people who live and work in those spaces for decades to come.
ROCKWOOL insulation is made from stone wool 5. Our entire range harnesses the power of these natural materials, creating insulation that is:
Loft or attic insulation can be installed by a local professional to ensure optimal performance.
If you are installing yourself, be sure to follow the product installation guidelines – these can be found on our product web pages.
Some key tips:
At ROCKWOOL, we make products that improve energy efficiency. But we also want to ensure the materials we produce, and how we produce them, are sustainable too.
All our stone wool insulation is made from volcanic rock, one of the earth’s most abundant and sustainable resources. What’s more, our production processes are designed around ambitious goals that go beyond just neutralising our impact.
Our manufacturing techniques include circular economy practices, re-using waste produced during the making of our and other businesses’ products. We take stone, the most abundant natural resource on Earth, and upcycled secondary materials that would otherwise end up as waste and turn them into long lasting stone wool insulation products. These products are themselves recyclable and can be recycled again and again without any deterioration in quality.
Because of this, after just 200 days, ROCKWOOL insulation will have saved more carbon than was used in its manufacture.
For further information, Environmental Product Declarations (EPDs) are available for all of the stone wool insulation products manufactured in the UK. To request an EPD for loft insulation, please contact technical.solutions@rockwool.com.
Financial support is currently available for eligible buildings and households through a home energy grant for loft insulation.
Visit Simple Energy Advice to find out more.
Check the Energy Savings Trust website to see whether there are any additional financial support schemes available for loft insulation.
ROCKWOOL products are designed to last the entire lifespan of a building. Stone wool material won’t decay and will perform for the lifetime of the building. 12 13
The recommended thickness is between 270 and 300mm, according to UK building regulations. This baseline is designed to help reduce energy bills and raise energy efficiency in buildings. 14
Rolled insulation and blown insulation suit different building needs. Rolled insulation can be more suitable when there is space to roll out the batts. Blown insulation can be helpful for coverage in hard-to-reach attic spaces.
