UK 'must
insulate 25 million
homes by 2050'

16th May 2017

Authors of a report to Parliament say that in order to meet the insulation standards required by 2050, more than one home every minute will need to be refurbished in the UK if we are to meet our carbon emission targets.

With the UK needing to cut carbon emissions by 80%, the targeting of inefficiently heated, draughty and poorly insulated buildings will be high on the government’s agenda - given refurbishment of properties of this kind will be expected to deliver over a third of the overall reduction. As a result, the emphasis on effectively insulating your home now couldn’t be greater.

The choice of insulation available on the market is varied, but there is much more to insulation than simply saving heat! Your choice of the type of insulation you use is an important decision, a decision that can have economic and environmental consequences for your home, workspace and the planet. Here at Eden Renewable Innovations Ltd, we believe that natural sheep’s wool insulation is the ultimate choice; a natural, breathable, renewable, biodegradable, safe, efficient and practical solution.

So consider:

Ensuring that your house is breathing, and moisture is able to escape is essential to the health of the building as well as the occupants.

Wool breathes through its’ very fibres, packed together creating millions of pockets, these fibres trap air and ensure homes are kept warm during the winter and cool in the summer.

When wool absorbs moisture it emits energy that warms the wool and so helps reduce condensation and can actually draw moisture out from timber and other building materials where condensation might otherwise be a problem.

As a chemically very complex fibre, wool is also able to readily bind and fix many airborne chemicals, thus making the air within the building cleaner to breathe. The fibres fix carbon during their formation, providing a mechanism to remove atmospheric CO2 .

Fibres such as wool and hemp contain approx. 50% carbon meaning that every tonne converted into insulation fixes the equivalent of nearly 2 tonnes of CO2 which can dramatically outweigh any carbon consumed in manufacture

Another thought to consider is the safety aspect. Wool is a kind fibre, itch free, safe and easy to install, so there is need for protective clothing when installing and it does not release damaging fibres into the atmosphere when cut.

The sound insulation properties of natural fibres are far superior to those of man-made materials due to their much higher density and the irregular nature of the natural fibres themselves.

The thermal conductivity of wool insulation products is equal to and often higher than conventional materials. Thermafleece CosyWool for example has a thermal conductivity of  0.0039 W/Mk.


Transporting low density insulation carries an environmental impact that can be reduced by compressing the materials. Here at Eden Renewable innovations Ltd, recycled polyester is combined with wool which enables a compression level of 60%, This has distinct and significant bearing on transport costs and fuel consumption whilst retaining the functional benefits of the wool.



Wool fibres not only trap escaping heat, they radiate heat when they absorb airborne moisture.

Wool absorbs toxins emitted from building materials such as formaldehyde

Wool insulation can reduce carbon dioxide emissions in a typical house by 1 ton per year.

Wool insulation is far more effective at absorbing noise than synthetic counterparts

Wool insulation is easy and safe to install!
