Loft Insulation

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:

• Ensure you have accurate measurements of the area you are insulating
• Inspect all existing joists and electrical cabling, to ensure proper condition. 
• If laying over ceiling spotlights, put light covers over them for ventilation. 
• Evenly distribute material and avoid open joints between products. When laying in layers avoid stacking joints.

Sustainability and energy efficiency

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.
