We are really pleased to introduce an established and proven provider of natural sheep wool insulation into the UK. The Sheepwool range carries the Nature Plus Seal a respected and coveted acknowledgement of its green credentials.
So what’s different?
No binders, no fillers just wool, the secret is in the manufacture; first the wool goes through the carding process to tease out the fibres it is then taken through a mechanical process which ties the fibres back together a sort of ‘weaving’ the result is a robust and durable product which is also soft, flexible and resilient. The only additive is a natural insect repellent. The process can vary the density, to allow stiffer rolls for vertical applications for example, whilst still ensuring it keeps its density and flexibility and so its ability to perform for many, many years.
10 things about the 100% natural Sheepwool range
- The only 100% naturally produced sheep’s wool insulation product on the market. NO Polyester as “filling” material and no binders.
- 100% Sheepwool has been awarded the coveted Nature Plus Seal and has European Technical Approval (ETA)
- 100% Sheepwool will keep its insulation value even if moisture is present in the building.
- 100% Sheepwool helps to prevent overheating in summer.
- 100% Sheepwool keeps it’s “loft” through the lifecycle, it does not slump or reduce in thickness over the years unlike polyester or fibreglass
- 100% Sheepwool helps to reduce the surface spread of flame.
- 100% Sheepwool uses only 15% of the energy to produce when compared with fibreglass and solid foam insulation.
- 100% Sheepwool is fully Biodegradable at the end of its life.
- 100% Sheepwool is irritant free and completely safe to use 100% Sheepwool has no harmful side effects –
Good things about Sheepwool insulation
- Wool is natural, renewable and sustainable
- Wool Insulation is perfectly safe to touch and requires no specialised safety clothing or equipment, making it easy to install
- It causes no irritation to the eyes, skin or lungs and wool fibres present no hazard to your health
- Wool fibres are breathable, meaning they can absorb and release moisture without reducing thermal performance unlike fibre glass based products
- Wool does not support combustion and will extinguish itself in the event of fire
- Wool Insulation does not settle due to the high elasticity of the wool fibres ensuring no loss of performance over time
Even better things about Sheepwool insulation
- Wool is designed by nature to save energy
- Wool Insulation also requires only a fraction of the energy to produce compared to that of man made counterparts
- This means that Wool Insulation will pay back its energy costs more than 5 times sooner (only 15 kW of energy are used to produce 1 m³)
Technical type things about Sheepwool
- Wool has a higher fire resistance than cellulose and cellular plastic insulation
- It does not burn, but instead singes away from fire and extinguishes itself (Wool has a very high inflammation point of 560°C due to its high Nitrogen content of ~16%) Wool is self extinguishing because of its high Limiting Oxygen Index (LOI=25.2), which means to completely burn wool an oxygen content of 25.2% is necessary whereas air only has 21%
- Wool fibres are hygroscopic by nature, meaning the can absorb up to 35% of their own weight from the surrounding atmosphere depending on the humidity, helping to preserve the surrounding timbers.
- While absorbing this moisture, wool releases energy in the form of heat, thus raising the temperature of its surrounding areas. Naturally releasing this moisture in the warmer seasons, wool creates a cooling effect on the same surroundings.
- Sheepwool Insulation rolls are produced to standard width requirements – saving time when fitting
- Multiple layered wool fibres effectively reduce airborne sound transfer
