An excellent solution to insulating pitched roofs at ceiling level, this loft roll from Earthwool boasts several unique features that make it ideal for such applications. Suitable for a range of different pitched roofs, it is great on both new builds and renovations. 

What is This Insulation Made From? 

This insulation has been created using low-density glass mineral wool. This material has been utilised in insulation products for many decades, and with good reason – it is an outstandingly high performing substance, with excellent durability and a long lifespan. 

What Thicknesses and Sizes are Available? 

This roll is available in several different thicknesses ranging from 100mm to 200mm. While thermal conductivity doesn’t change with the roll thickness, thermal resistance does – it increases alongside the thickness. For example, 100mm rolls have a thermal resistance of 2.25 m2K/W, while 200mm rolls possess a thermal resistance of 4.50 m2K/W.  

Is Knauf Earthwool 44 Resistant to Mould and Moisture?  

This roll is highly resistant to damage posed by water vapour and mould. It is rot-proof as well as odourless, meaning that it can last for many years in your ceiling without the need for replacement due to wear or damage. 

Is This Insulation Resistant to Fire?  

This roll achieves an A1 fire rating. This is one of the highest achievable fire resistance accolades on the Euroclass Fire Ratings scale. The roll is non-combustible and is not only resistant to fire-induced damage, but its properties mean it will not aid any flames in spreading. 

What level of thermal insulation does this board offer? 

The loft insulation roll has a thermal conductivity of 0.044 W/mK – this means this product is capable of exceptional levels of insulation. The quilt is unfaced, meaning the thermal conductivity levels are consistent throughout the material. 

Is Knauf Earthwool 44 Environmentally Friendly?  

This roll benefits from a Green Guide Rating of A+ - this is due to the lack of certain environmentally damaging properties, as well as a cleaner production process than many other insulation types. For example, it contains no ozone-depleting substances (ODP). 

Where Can This Insulation Be Used?  

This insulation has been created specifically for the ceiling of your building, where its various features allow it to perform at its very strongest. Designed for cold pitched roofs in particular, it is a testament to the manufacturer's ability to create highly effective specialised insulation products.

Delivery Information

We understand that ordering products online can be daunting, especially when ordering roofing materials. It is for this reason that we make our delivery processes as simple as possible for you. However, there are a few things to know about our delivery processes. These include:

  • When placing an order, you’ll see a breakdown of your delivery charge in your shopping cart. These charges are for the UK mainland only, and additional charges may apply for Northern Ireland, the Scottish Highlands and other regions.

  • Deliveries only take place on working days (Mon - Fri) and do not take place on Bank Holidays. 

  • You’ll find an estimated delivery on the majority of product pages below the 'Add to Basket' button. Whilst we aim to deliver your items within the estimated delivery, it is only an estimate. 

  • You're able to select a preferred delivery date in your shopping basket. Whilst we aim to deliver your items on this date, it is not guaranteed.
  • Orders placed after 12pm, during the weekend, and on a bank holiday will not be processed until the next working day. Please consider this when placing your order as it may impact your delivery date.

  • After you’ve placed your order, you’ll receive an order confirmation by email outlining the details of your order. Please check your order confirmation email and inform us of any mistakes or errors immediately.

  • Shortly after receiving your order confirmation you’ll receive a separate email confirming the planned delivery date.

  • We can only provide a delivery date and are not able to confirm the time delivery will be attempted. Therefore, we ask that somebody is able to accept and sign for your items throughout the started delivery date.

  • If you are unable to accept and sign for an order, it can be left in a safe location in most circumstances. Please email [email protected] if you would like an item to be left without a signature. 

  • Whilst we aim to hold the majority of our products in stock, due to the vast number of products we offer this is not always possible. Because of this we are required to send your items directly from the manufacturer on a small number of occasions, at which point a different delivery charge may apply as standard.  

  • On occasions the items ordered may be shipped from different depots, which could result in seperate deliveries taking place.

If you have more questions about our products or delivery, please contact our team online or by telephone.
