Disadvantages of Sheep Wool Insulation

sheep wool insulation pros and cons
 

Sheep wool is a wonderfully versatile and useful material that we humans use in a range of applications. This is a renewable energy source, which is one of the material’s biggest advantages. From clothing to loft insulation, sheep wool can be utilised for a number of different reasons.

Ultimately though, it is the thermal qualities of this material that we get the most use out of. From jumpers to cavity wall filings – the whole point is to keep something warm and thermally protected.

But are there any disadvantages of sheep wool insulation? Is this material the way to go with your own roof space? Read on to find out…

The Positives

As mentioned above, wool is a renewable material source that requires a shearer and a set of clippers to obtain. Sheep are everywhere, and there is no danger of us running low on this livestock anytime soon.

The material also boasts high elasticity and causes no irritation to the eyes, skin or lungs. Not only that, this material can also breathe, allowing for an ability to absorb and release moisture from the air.

Disadvantages of Sheep Wool Insulation

The Disadvantages of Sheep Wool Insulation

So now we know the positives, what about the disadvantages of sheep wool insulation? The most obvious drawback to sheep wool is the cost. This choice of insulation material is a lot more expensive than most other alternative methods and products.

The rise in expense is expected and obvious considering its organic origin, and its common use within other industries and applications. Logistics and availability are the two biggest issues affecting the cost here.

Also, in Britain, we have building regulations in place that state a requirement for at least 270mm of insulating material between the joists in a loft. Standard timber height rarely reaches over 150mm, so you will need to squash the wool leading to a loss of thermal insulation quality.

The material isn’t completely process-free either, as sheep wool is treated with Borax to prevent insects and fungi growth.

Borax isn’t a direct health hazard to us as humans, but it has caused reproductive problems in laboratory animals when exposed to large doses. So as you can see by the disadvantages of sheep wool insulation, this choice of material is not the greatest.

Harsh Chemical Use

Perhaps the most concerning disadvantage of sheep wool insulation is the linked cleaning and associated preparation processes. Before being released onto the home improvement market, the wool must be treated and cleaned in order for it to be effective and suitable for use.

This involves a lot of harsh chemicals used to disinfect the material, and to treat possible infestation from scab mites. In turn, this can leave organophosphates behind in the wool, that are proven to cause a number of different neuropsychological health issues.

Trust Home Logic and Try Spray Foam Instead

For a far more cost-effective option that performs just as well as wool, if not even better, take a look at spray foam insulation. This product is fairly new to the UK market but people in the US and Canada have been enjoying the benefits of spray foam for some time now.

And there are some pretty harsh environments over the pond! Revolutionary in its design and application, spray foam carries all the benefits of sheep wool without any of the associated drawbacks. Plus, it’s cheaper too!

Spray foam has incredible thermal qualities and provides an air-tight but breathable seal around your entire roof-space. This also allows you to control the effects of moisture, by not allowing the damp to enter your building.

This all-encompassing approach reduces heat loss through the roof, and also helps to reduce the amount of external noise entering your property. So all in all, the entire interior environment of your home is improved tenfold, whilst you save money on your energy bills simultaneously!
