What is Earthwool made from?
Earthwool is a new glass mineral wool designed to improve upon the already exceptional environmental credentials of standard glasswool by increasing the use of both sustainable and recycled raw materials.

How is Earthwool different from other glasswool?
Earthwool improves the already exceptional environmental credentials of glass mineral wool and is manufactured with an increased use of sustainable raw materials and recycled glass (which result in the distinctive brown colour). It has a higher thermal performance than our standard loft roll(0.040 W/mK Lambda value).

Why is Earthwool brown?
Earthwool is brown in colour resulting from the use of new, more sustainable raw materials including glass and other ingredients. The brown is the products natural colour i.e. It does not contain any colour additives or dye

What thicknesses of Earthwool are available?
Earthwool is available in 100mm and 200mm thicknesses – 100mm fits nicely between your ceiling joists, and 200mm lays across the joists to give a total depth of 300mm.

What is the thermal performance of Earthwool?
Earthwool has a lambda value (also called Thermal Conductivity) of 0.040 W/mK.

How much loft insulation do I need?
To meet current Building Regulations you need a minimum of 270mm of mineral wool insulation. With Earthwool, we recommend 100mm between the ceiling joists and 200mm laid across the joists. This will achieve a better U-value than the requirements of the Building Regulations, and provide additional long term reductions in the energy usage and CO₂ emissions associated with the dwelling. For top-up only, just use 200mm across the joists

How do I find out how much loft insulation I have?
Simply push a tape measure or ruler down the side of a piece of loft insulation until it hits the plasterboard ceiling and read off the depth.

How do I know how many rolls I need to insulate my loft?
First, you need to find out the length and width of your loft. You can do this by using a tape measure to measure the length and width of your house (in metres) or, if you don’t have a tape measure, a large stride equates roughly to 1 metre. Once you have these measurements, enter them in our calculator here, choose the thickness(es) of Earthwool you require and click calculate.

How long would it take me to insulate my loft?
Once you have cleared any stored items out of the loft, allow about 3 hours for installation in an average sized (about 25m2) loft. You will need to install one layer of 100mm between your ceiling joists, then a second layer of 200mm on top (cross layered) to comply with current Building Regulations.

Will Earthwool deliver right into my loft?
No. We will deliver it to the room of your choice or even right under your loft hatch, but not actually up into your loft.

How long will I have to wait for my order to be delivered?
You should allow 28 days for delivery. However, the vast majority of orders will be delivered within 14 days, and depending on where you live and on what day you place your order, delivery can be a quick as 3 days.

Can I return any unused Earthwool?
No. Unfortunately, due to the size and weight of the rolls, we cannot take back any product that has been delivered, except as specified in our Terms & Conditions.

What are Knauf Insulation mineral wool products with ECOSE™ Technology made from ?
Knauf Insulation mineral wool products with ECOSE™ Technology form a new generation of mineral wool insulation, which employ a revolutionary, new bonding agent made from natural and more sustainable organic materials than the non-renewable, phenol-formaldehyde based resins currently used.
back to top

Why are mineral wool products made with ECOSE™ Technology more sustainable than the comparable standard available products ?
All Knauf Insulation mineral wool products are inherently sustainable — they have high recycled and renewable content and save hundreds of times more energy in use than required to manufacture them. However, glass and rock mineral wool made with ECOSE™ Technology are even more sustainable, as they have the added benefit of using a natural resin, which is 70% less energy intensive than traditional binders. With ECOSE™ Technology, rapidlyrenewable organic materials replace the traditional chemicals used in standard insulation binders to create more advanced and sustainable products. And, since there is no formaldehyde or phenol used with ECOSE™ Technology, it also helps to reduce our carbon footprint even further.

What is the health risk of formaldehyde in existing products ?
Formaldehyde has recently been reclassified by the International Agency for Research on Cancer (IARC) as a carcinogen. This has increased the focus on building products which contain formaldehyde or include it in their manufacture. A large number of tests conducted by independent expert laboratories in many countries have shown that, mineral wool products are an insignificant source of formaldehyde within buildings and therefore not a risk to the health of occupiers or installers. However, the use of ECOSE™ Technology will remove formaldehyde from the supply chain and increase the confidence with which mineral wools can be used.

How is mineral wool with ECOSE™ Technology distinguished from the traditional mineral wool, in a visible way ?
The products distinguish themselves by colour and of course packaging. With the new technology the mineral wool colour results in a distinctive natural brown colour, which we did not choose, it occurred naturally! The ECOSE™ Technology brand and logo are clearly visible on all packaging where this new technology is used and serves as your complete assurance that there is absolutely no formaldehyde, acrylic, phenol, dye or artificial colours added in the chosen Knauf Insulation product. Currently ECOSE™ Technology is applied on plants which also manufacture traditional products. During the transition to full production with ECOSE™ Technology, products may be produced with small residues of conventional binder.
back to top

Why was ECOSE™ Technology selected, if current products are considered sustainable ?
Sustainability is also about continuous improvement, pushing the technical boundaries. We believe there are always opportunities to improve. This development was driven by our intensive research & development programme to fulfil our desire to provide customers with innovative products to meet the growing market need for more sustainable construction materials — and by our company-wide commitment to greater sustainability in all aspects of our business.

How is Knauf Insulation mineral wool with ECOSE™ Technology different from traditional glass and rock mineral wool ?
It improves the already exceptional environmental credentials of both glass and rock mineral wool, because it is manufactured with a brand new kind of binding material which reduces the already low environmental impacts in manufacture whilst still providing superior product performance. It is also formaldehyde-free.
back to top

How does mineral wool with ECOSE™ Technology perform compared to traditional mineral wool ?
Where assessed to insulation standards, like EN 13162 and ASTM C665, glass and rock mineral wool products with ECOSE™ Technology have the same industry-leading performance as other Knauf Insulation glass and rock mineral wool products, with the additional benefit of being more environmentally friendly, sustainable and easier to handle.
back to top

What testing have Knauf Insulation mineral wool products with ECOSE™ Technology gone through ?
The products have undergone a comprehensive and rigorous evaluation to determine their environmental effects and acceptability in use and indicate that products with ECOSE™ Technology improve on the already excellent performance of conventional mineral wool products. As with all Knauf Insulation products, the new products comply to the (regional) applicable standards, like for example health and safety standards, quality certification for mineral wool products and CE-marking for Europe, as well as ‘Underwriters Laboratories’ criteria (UL) in North America.

What is the warranty of the mineral wool products with ECOSE™ Technology ?
The same as for our conventional glass and rock mineral wool products.
back to top

Why is ECOSE™ Technology not yet used on the total mineral wool product range of Knauf Insulation ?
It will be ! The technology has been applied successfully to glass and rock mineral wool and will be gradually introduced throughout our entire range, in line with our customer demand.
back to top

Will all Knauf Insulation mineral wool products be made with ECOSE™ Technology ?
There will still be standard mineral wool products available from Knauf Insulation as long as customers continue to demand them.
