Celebrate Wool Month with natural wool insulation

Celebrate Wool Month with natural wool insulation

Posted by Sarah, Celtic Sustainables on 6th Oct 2025

Campaign for Wool 2025  -Live naturally, choose wool insulation!

The Campaign for Wool’s 15th anniversary serves as a timely reminder: when you opt for wool, you select a fibre that is natural, biodegradable, renewable and truly worthwhile.

The global campaign for wool, backed by British Wool, highlights the natural, renewable, and sustainable qualities of wool, including its use in products like Thermafleece insulation and Truewool insulation. Led by its patron, Prince Charles, the campaign aims to educate consumers about the benefits of wool in various applications. Throughout the month, there's a buzz of activities, promotions, and workshops promoting the benefits of wool and its sustainable qualities.

You can get involved too! Share your wool photos on social media using the hashtag #Woolmonth. Whether you've used wool insulation in a van conversion, garden shed, or home renovation, share your experience! Inspire others and pass on leftover insulation to share the benefits with others. Don't forget to include #Celticsustain and #Woolmonth. Join the movement today!

Now, let’s delve into some of the reasons we love wool insulation:

  • Wool is a natural insulator, making it an effective and sustainable choice for thermal insulation.
  • Sheeps wool helps maintain warmth in buildings, contributing to energy efficiency.
  • Wool improves indoor air quality, reduces noise, and is flame-resistant, enhancing safety and comfort.
  • Wool is also suitable for people with allergies due to its hypoallergenic and antibacterial properties, making it a healthy option for many.
  • Natural fibre Insulation is naturally breathable, providing a comfortable living space.
  • Did you know wool insulation can absorb moisture? It can hold up to 30% of its weight in water, efficiently regulating humidity, buffering against temperature fluctuations, and helping to prevent condensation, mould, and dampness.
  • Our range of natural fibre insulations is safe and straightforward to handle for DIY Installation.
  • All manufactured in the UK with a minimal carbon footprint.

Wool is cool! Keeping a house cool in summer and warm in the winter.

We sell insulation by the roll!

If you’ve been comparing prices between our website and other suppliers, you may have noticed some differences in prices and coverage. Don’t worry. That’s because we sell our products by the roll, and the prices and coverage shown on our website are based on one roll.

Why do we do this?

We’ve found that selling by the roll makes things simpler and more convenient for you:

1. Flexibility for your project – It’s easy to choose just one or two rolls in the size you need, or mix and match different sizes. This is perfect for smaller projects like topping up loft insulation or insulating a campervan.

2. Fast, efficient delivery – Smaller orders are quicker to dispatch with couriers like DPD. Each roll is carefully boxed and shipped individually, ensuring your order arrives safely (it won't roll off a courier's conveyor belt) and promptly.

Cosywool Sheep’s Wool Insulation

Thermafleece Cosywool roll is crafted from a rich blend of wool fibres that are thermally bonded to boost durability and prevent slumping once installed. Wool is an outstanding natural fibre; as a sheep’s fleece grows, it absorbs carbon dioxide from the atmosphere.

When used as insulation, wool traps and removes many airborne pollutants that can harm us, helping create a healthier indoor environment. Plus, using Thermafleece insulation is one of the most effective ways to achieve substantial energy savings in your building.
