The Premium Sheep Wool insulation applies new technology to create a high-density wool insulation that can be applied quickly to give superior levels of insulation.
It can be applied to floors, ceilings and walls.

It is made in a unique way with a concertina structure which gives it the premium density and structural integrity but also means it can very easily be cut to size simply by ripping the material by hand. There is no requirement for any cutting equipment to fit the Premium Sheep Wool insulation.

Raw density: 20kg / m³

Thermal conductivity tr 0,0359 W/mK

The SheepWool Premium insulation can be applied in floors, ceilings and walls. Have a look at the diagram to see applications of Premium sheep wool insulation: 55200-Sheepwool Insulation-Brochures 4pp A4. This product particularly lends itself to being applied in walls, which the value product Comfort is not suitable for.

It is made in a unique way with a concertina structure which gives it the premium density and structural integrity but also means it can very easily be cut to size simply by ripping the material by hand. There is no requirement for any cutting equipment to fit the Premium Sheep Wool insulation.

Other sheep wool insulation products have an element of plastic fibre added to give it the required “loft”. If the wool was to squash down, it wouldn’t be nearly so effective in keeping your home warm. Insulation works effectively by trapping air. That acts as a buffer to prevent warmth from getting out, and cold from getting in. The Premium Sheep Wool Insulation has been cleverly engineered to do this and retain its loft for decades, without the addition of any other materials. It’s 100% wool, 100% chemical free, 100% moth-proofed.

Watch Chris demonstrate how easy it is to fit! “our installer here is wearing no gloves, no mask, no nothing…”

What other sheep wool insulation products are available?

As well as the Premium range, there is Comfort and Optimal.

Comfort Sheep Wool Insulation is a cost-effective product that can be used in floor / ceiling applications. It comes in 100mm and 150mm thicknesses. It has a density of 14kg per cubic metre and thermal conductivity of tr 0.042 W/mK .

Optimal comes in 50mm and 75mm thicknesses, and is smoothly felted on one side for stapling to vertical surfaces. It’s also good for giving a top-up to existing insulation. It’s a medium density sheep wool insulation being 18kg per cubic metre. It has a thermal conductivity of tr 0.0385 W/mK

Why use sheep wool for insulation?

Sheep wool is the perfect natural insulator. It’s made by the same Austrian company that magics our Herdwick wool into mothproof felt for our Chimney Sheeps. They make three different densities of insulation that are suitable for different applications. It is made of 100% wool without any plastic fibres that many other sheep wool insulations have.
This makes it a bit more expensive but it is 100% wool, 100% mothproof, 100% chemical free.

It is safe to handle and apply, requiring no gloves, dust mask or safety equipment. It will last for decades but at the end of its life can simply be composted. There are no plastic fibres or chemicals in any of the SheepWool Insulation® products.

They have all been moth-proofed using the patented and very clever Ionic Protect® treatment. This changes the ionic charge of the wool fibres, so that moths don’t even recognise it as wool and fly on by. Other moth deterrents rely on the moth larvae eating a little bit of the product in order to be poisoned by the treatment – this means a little bit of it deteriorates each time a moth larvae chews on it. Not with the Ionic Protect®. It looks like wool to us, behaves like wool for us – it is wool! but clothes moths and carpet beetles are tricked into looking elsewhere to dump their load of eggs to hatch into a hoard of wool munching monsters.

All the insulation products are designed to fit between standard joists 400mm and 600mm apart, so all the rolls are 380mm and 570mm wide to fit snugly between the joists. The narrower rolls are sent in packs of 3, and the wider ones in packs of two.

What are the benefits of wool?

Ever so many! Here are but a few.

Wool has excellent insulation properties, keeping buildings warm in winter and cool in summer.

Wool is an excellent natural sound absorber and sound insulator.

Wool is hygroscopic, so it will readily absorb water from the air. If you’ve got a damp home, the wool can help absorb moisture then wick it away when there’s enough airflow to dry it out. It can absorb up to 33% of its own weight without feeling damp.

Wool is hypoallergenic – it is resistant to bacteria, mould and mildew that can trigger allergic reactions in many people.

Wool is naturally breathable, allowing air and moisture to move and circulate in a space (purifying air that moves through the wool), but still insulating and keeping your home warm. Think of it like a nice feather duvet, that keeps you snug and warm but still permits moisture and air to percolate through.

It is shorn annually from sheep who must have their fleeces clipped for their own welfare.

Wool is a carbon store. The 100% wool insulation will last for decades, but at the end of its life it can be re-engineered into another product or composted.

Wool absorbs VOC’s – high volatile compounds – such as formaldehyde. These are in the air all around us, especially in new products and furniture, things that have been varnished, things that smell “new”. The VOC’s bind permanently with the keratin in the wool fibre. Read more about it here.

What’s wrong with VOC’s?

They can cause irritation to eyes, nose and throat. They can cause shortness of breath, headaches, fatigue, nausea, dizziness and skin problems. Higher concentrations of VOC’s may cause lung irritation, and damage to the kidneys, liver and central nervous system.
