Knauf Earthwool Dritherm 32 is a mineral wall batt used to insulate external masonry walls up to 25m in height. Dritherm 32 also utilises innovative materials to provide added fire protection and combat moisture transmission.

Overview

  • Brilliant thermal insulation with thermal conductivity of 0.035 to 0.037 W/mK
  • Slabs ‘knit’ together when bundled to eliminate air gaps
  • Excellent fire protection with Euroclass A1 Non-combustible accreditation
  • Repellent to water to minimise moisture transmission
  • Environmentally friendly with a zero Ozone Depletion Potential

Brilliant Thermal Insulation

The Knauf Earthwool Dritherm 32 offers brilliant thermal efficiency through the use of a glass mineral wool. This cavity wall insulation provides a thermal conductivity of 0.035 – 0.037 W/mK dependent upon the thickness. When combined with other building materials, this allows you to significantly reduce a building’s U-value and meet the requirements of national building regulations.

Excellent Fire Protection

Ensuring your cavities are filled with a non-combustible material is essential. Dritherm 32 has been accredited as Euroclass A1 Non-combustible, which requires that the materials used will not aid the spread of fire. You can therefore be confident in the fire protection this Knauf insulation provides.

Prevent Moisture Transmission

Knauf Earthwool Dritherm 32 features water repellent fibres, therefore ensuring the insulation remains dry. These unique fibres also prevent any moisture transfer from occurring. In doing so, it minimises the chance of dampness or rot from occurring within wall cavities of your property.

Ideal for a Variety of Projects

Each slab of Dritherm 32 is 455mm wide to make installation hassle-free. You also have a choice of various thicknesses between 75 – 100mm. You can also place slabs upon each other for additional thickness, at which point they will ‘knit’ together to eliminate air gaps.

Delivery

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.

Refunds

We understand mistakes can be made and we therefore keep our cancellation and returns policy as simple as possible. However, there are a few things to know about cancelling an order or returning an item. These include:

Items Not Required

Should you no longer require an item, you have the right to cancel within 14 days of delivery unless the items are made to order. You needn’t give us reason for cancelling your order but will be required to notify us by email. Once notified we will provide an address for the items to be returned to and arrange the necessary refund.

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 within 48 hours and may require images. To avoid such an issue, we ask that customers do not sign for damaged goods.

Made to Order Items

A handful of items are ‘Made to Order’. This means they are typically manufactured to the specifications provided by you and are therefore non-refundable. This is unless they are deemed to be faulty or damaged at the time of delivery, at which point you should notify us by email within 48 hours of delivery.
