Cleverly crafted using home-grown hemp fibres, Thermafleece NatraHemp is a reliable, safe and highly efficient insulation product, perfect for use in walls, roofs and flooring. As hemp is such a fast-growing plant, the fine, low-impact fibres are ideally suited for use in insulation. Fitting between rafters, joists and studs, this high-quality insulation provides an impressive thermal conductivity rate of 0.040 W/mK with a far superior level of insulative performance in comparison to lower density insulation products. It is non-hazardous and 100% safe to handle, cut and install within the home.

Brilliantly sustainable, Thermafleece NatraHemp can reduce your carbon emissions by many tonnes over its entire lifetime. The hemp-fibres fix carbon dioxide which helps to effectively minimise levels of greenhouse gas and CO2 being released into the atmosphere. With the use of a high-quality insulation such as NatraHemp, you can provide excellent insulation for your home, lowering the amount of energy lost and reducing both energy consumption and costs. In fact, this impressive insulation produces such high energy savings, that it pays for itself within just a few years.

Not only does Thermafleece NatraHemp ensure exceptional thermal insulation, but with a density of 25 kg/m3, it also offers great acoustic insulation throughout a multitude of systems. Better yet, by regulating moisture content in the building, NatraHemp can even contribute to a healthier home environment.

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 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.

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.
