To ensure that the insulation maintains its shape throughout its service life Thermafleece uses a synthetic binder.  There are no natural materials available that can do this. Consequently every effort has been taken to ensure that the virgin polyester content is kept to a minimum.

Thermafleece will not contribute towards the developmental stages of fire. Thermafleece sheep’s wool  insulation complies with British Standard BS 5803-4 for flammability and resistance to smouldering.

Thermal performance of Thermafleece CosyWool is approximately 10% more thermally efficient than low density glass fibre insulation. Thermafleece UltraWool is more than 20% efficient

Sheep’s wool is the best acoustic insulation.  Because of their irregular surface, shape and density, natural fibres such as sheep’s wool are very effective at disrupting sound. That’s one of the reasons why sheep’s wool insulation can provide acoustic performance comparable to the best mineral fibre products.

The environmental benefits of  sheep’s wool insulation are many. At Thermafleece we use the coarse coloured wool from hardy hill sheep which would otherwise go to waste to make our thermafleece sheep’s wool insulation. All our wool is British and we manufacture in Yorkshire, the home of British Wool.

Each kg of natural fibre locks up about 2 kg of carbon dioxide which helps remove CO2 from the atmosphere. Furthermore, once installed in your property Thermafleece will last the life of the building significantly reducing the impacts of replacement and repair.

Thermafleece is breathable, allowing a healthy moisture balance which helps protect the building fabric and health. It helps your building stay warm in colder months, helping to reduce energy bills whilst the higher thermal mass buffers the heat to reduce overheating in summertime.  It is very effective at lowering sound levels within the building and is itch free, safe and easy to install.

The density of Thermafleece varies from 18kg/m3 to 32kg/m3 depending on the product. To clarify refer to product fact sheets for details – available to download from our product information pages.

Thermafleece insulation can’t be used as insulation in cavity walls of brick and block or block and block. It can be used within timber frame walls or within a frame on the inside of a solid wall.

All the insulation we supply is completely safe to handle. However, because lofts are inherently dusty places, we would always recommend using protective equipment when working in a loft.

Do you want to know how thermafleece sheep’s wool insulation is made?  Take a look at The Campaign for Wool video.  It will show you the thermafleece production process from start to finish.

Yes, Thermafleece is made from British Wool.

All the wool used in our Thermafleece sheep’s wool insulation comes from British flocks, roughly split between England, Scotland and Wales. British flocks are relatively small in size compared to larger wool producing nations like Australia. The sheep we use for Thermafleece run free on the mountains and fells and are brought down to lower lying land in the winter. They are not housed indoors although in lambing season the ewes may be brought under cover to protect them.

All the wool clip comes from live sheep that are shorn in the spring of each year. All our wool is purchased through British Wool which is the government agency that manages the supply of all British wool bought and sold within the UK. They also conduct training and promote welfare. Our wool is only purchased at the British Wool auctions by a licenced wool merchant.

We are a British Wool licensee. Both British Wool and our company take animal welfare very seriously. You can find information on animal welfare on the British Wool web site:

You would definitely need a vapour control layer in this application. The outer metal skin of the van will produce a heavy condensation point without a control layer and possible deterioration of the insulation could take place.

Thermafleece CosyWool Roll is delivered compress packed – this allows us to increase the number of packs we can get on a pallet and therefore minimise transport costs.

Once your CosyWool Roll is unpacked it will regain to its full depth within 5-7 days . It will continue to regain whilst in situ.

How to Cut Thermafleece: Although tearing thermafleece to fit is self-explanatory, cutting Thermafleece accurately is always a good topic for a discussion.

Roll and Cut Method: Tools Required: Sharp Scalloped Edge Knife or Insulation Saw
FOR AN ACCURATE LENGTH: If you have a slab or a roll and want an accurate length, take the insulation and  roll it as tightly as possible along the width. Measure where you need to  cut to give you the length you require. Taking the insulation saw / knife  easily cut through. This provides a nice, neat edge and is an alternative to tearing by hand.

TO CUT THE WIDTH OF THE ROLL: Keep the insulation rolled and do not unwind. Measure the required width that you need then using the knife or insulation saw begin to cut through the whole roll.

Compressing between boards: You can also cut Thermafleece by tightly compressing or clamping the insulation between two pieces of solid 15mm board. Overhang the fleece where you want to cut keeping the two board edges aligned. Saw cut the edge using a sharp, scalloped edged knife and keep the blade firm and square against both board edges throughout. Trim any fine remaining fibres with large scissors or shears.

Yes, SupaSoft is an insulation suitable for campervan conversions. Place between the campervan panels or simply lay on top of existing van insulation to improve overall insulation performance. SupaSoft insulation is an open non-woven material that allows water vapour to pass through the insulation and does not support mould growth.

It takes an average of 10,000 waste plastic bottles to produce enough SupaSoft to insulate a typical loft. That’s 10,000 plastic bottles that would otherwise have been buried in landfill, incinerated or left to litter the environment.

‘Let’s stop using things once and start dealing with the legacy we have created. SupaSoft Insulation provides a long term use for waste plastics that helps reduce home energy at the same time’ – Eden Renewable Innovations Ltd

SupaSoft is made from recycled PET (polyester) and is extremely durable. Because the binder is made from PET it does not degrade or slump over time. This means that SupaSoft will last the life of the building so once installed there is no need to replace.

Insulating with SupaSoft recycled plastic bottle insulation is a very cost effective alternative to fibreglass or other mineral insulation.  In addition the energy it saves means SupaSoft insulation quickly pays for itself.

You can lay SupaSoft on top of existing insulation although the amount of additional insulation will depend on how much existing insulation is in place and what condition it is in. For instance, if the insulation is in very poor condition we would recommend adding 250mm of SupaSoft on top. However if the existing insulation is in very good condition, add sufficient SupaSoft to achieve a total insulation thickness of 270mm. Check under and around existing insulation for any signs of damp or water damage.

Thermofloc is a loose fill cellulose insulation made from recycled newspaper combined with a mineral fire retardant.  A sustainable and cost effective way to insulate horizontal surfaces such as your loft or floors.

The U-value achieved will depend on the thickness of Thermofloc.  However a thermal conductivity of 0.039 W/mK ensures a consistent high performance envelope of Thermofloc insulation helping minimise heat loss in the winter and keeping your building comfortably cool in the summer.

Install Thermofloc at a density that provides additional thermal mass to the building envelope.  Therefore helping smooth out highs and lows as the building fabric warms and cools.

Yes  you can use Supasoft in a stud application. The wall must be in good, dry condition, no damp. There would also have to be a vapour control layer between the internal finish and the insulation to limit moisture migration.

Yes, SupaSoft recycled plastic bottle insulation can be used in a wall application. The wall must be good, dry conditions and with no damp. There would also have to be a vapour control layer between the internal finish and the insulation to limit moisture migration.

Supasoft is an ideal product for use in a suspended floor application. It is a permeable product and it has no intrinsic food value for moth or beetle. There will also be a good acoustic result.

Attach the insulation to the inside of the van using either strong double sided carpet tape or contact carpet adhesive.

There are approximately 800 recycled plastic bottles in every pack of SupaSoft, so that equates to 136.7 per m2
