What are the Main Features of This Insulation? 

This particular slab has been designed with durability in mind. Due to its desired use on external cavity walls, it is remarkably sturdy and has been produced to resist such hazards as mould, condensation and more. It is also non-combustible, meaning it is highly resistant to fire. 

What Materials Were Used in the Making of This Insulation? 

Made from a glass mineral wool created to last, this slab is an example of more traditional external cavity wall insulation methods. The materials in this product have been used in insulation for many decades now, and with good reason – they perform extremely well. 

What Level of Insulation Does This Insulation Offer? 

This particular slab possesses a thermal conductivity of 0.032 W/mK, which is again ideal for residential buildings. An insulation slab with this level of conductivity is guaranteed to continue to perform well throughout the year. 

Where Can This Insulation Be Installed? 

This slab has been specially designed for use within external masonry cavity walls. Knauf has consciously created this specialised slab to be perfectly adapted to such areas, which allows it to perform to noticeably higher standards. 

Is This Insulation Environmentally Friendly? 

Unlike many insulation products available, this roll has been produced using tools with no Ozone Depletion Potential (ODP) and no Global Warming Potential (GWP). To rate ‘zero’ in both these areas is rare, and makes this roll ideal for newer builds.

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.

Faulty or Damaged Items

On the rare occasion that an item is delivered faulty or damaged, we will exchange it or provide a refund. We must be notified by email as soon as possible and may require images. To avoid such an issue, we ask that customers do not sign for damaged goods.
