Is the Rockwool Flexi Slab Resistant to Moisture?  

Much like the hardy volcanic rock this slab is produced from, Rockwool Flexi is highly resistant to various forms of potential damage, particularly condensation and moisture. The Flexi Edge will also help to prevent cold spots by aligning and snugly fitting alongside timber frames. 

Is This Insulation Resistant to Fire?  

Able to withstand extremely high temperatures, the Rockwool Flexi Slab easily achieves a Euroclass A1 Fire Rating. It is non-combustible and will not only resist fire damage but avoid serving as a means through which the flames can spread. Therefore, providing your family and property further protection.  

What Level of Thermal Insulation Does the Rockwool Flexi Slab Offer? 

While the acoustic properties of this slab are absolutely outstanding, the thermal conductivity it possesses cannot be understated either. This slab has an impressive thermal conductivity of 0.038 W/mK – more than suited for most residential walls and floors. Allowing you to achieve a comfortable living space throughout the year.  

Is This Insulation Environmentally Friendly?  

Designed with the preservation of the environment in mind, the resources used to make this slab have been sustainably sourced. The production processes used in the creation of the wool have both zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP). This makes the Rockwool Flexi Slab ideal for environmentally conscious homeowners.  

Where Can the Rockwool Flexi Slab Be Used?  

This slab can be applied to both walls and floors, and its acoustic and thermal properties will be extremely effective in both. Minimising both acoustic and thermal bridging, the noise-reduction results of this insulation slab compared to others on the market is undoubtedly noticeable, with exceptional results.

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.

Refund Information

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 custom made. 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 as soon as possible and may require images. To avoid such an issue, we ask that customers do not sign for damaged goods.

Custom Made Items

A handful of items are ‘Custom Made’. 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 as soon as possible.
