Is Rockwool RWA45 Resistant to Moisture?  

Due to it being manufactured from a hardy volcanic rock, this slab is naturally resistant to the damage caused by moisture. Meaning it is protected from mould and rot, extending its lifespan and ensuring its effectiveness years into the future.  

Is This Insulation Resistant to Fire?  

Able to withstand temperatures upward of 1000C, the Rockwool RWA45 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. Helping to protect both your family and property should a fire occur.  

What Level of Thermal Insulation Does the Rockwool RWA45 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 0.040 W/mK – more than suited for many residential walls and floors. This will allow you to create both a comfortable warm and peaceful living space for the entire family.  

Is This Insulation Environmentally Friendly?  

Designed to minimise environmental impact, the resources used to make Rockwool RWA45 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). Therefore, this insulation does not only reduce the energy used by households but doesn’t significantly damage the environment during production.  

Where Can the Rockwool RWA45 Be Used?  

This slab can be applied to both walls and floors, and its acoustic 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

Click here for information on how Coronavirus (COVID-19) is impacting deliveries. 

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 sales@roofingmegastore.co.uk 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.
