What is Knauf Earthwool loft roll 44? 

As one of the most established materials for loft insulation, the Knauft Earthwool loft roll is manufactured using Knauf’s unique bio-based binder, ECOSE® Technology, and is available in a range of thicknesses. They also contain no ozone-depleting substances or greenhouse gases, making them a sustainable choice for your building works. 


These rolls are easier to install than other, rigid boards as they adapt to slight imperfections in the substrate and knit together. This means it prevents any air gaps, which would impact the performance. 

In addition, the non-combustible insulation is compression packed and lightweight for easy handling and transport.

Customer Questions
How do I cut loft roll?
Knauf loft rolls are 'combi cut' for ease of application. If the size doesn't match your requirements then the whole roll can be cut easily when in the pack, using an insulation saw or sharp knife with a plain or serrated edge.
What is the weight of 1 100mm roll? can I carry it myself to the loft?
The Knauf loft roll at 100mm weighs approx 13kg. The size of the product can make moving the rolls awkward and care should always be taken.
I have read that Knauf uses ECOSE technology, what is this?
ECOSE technology used on the Knauf mineral wool rolls is a bio-based binder which makes the product softer to touch and easier to handle during installation, while also minimising the level of dust caused.
Where are the products manufactured?
The Knauf rolls are manufactured in the UK, at the Knauf plants in Wales.
My timber joists are at 400mm centres. Do you supply a roll 400mm wide?
Knauf loft rolls are supplied at approx 1200mm widths, however these are perforated at 400mm and 600mm centres allowing you to easily cut/tear the roll to the required width.
