What better way to insulate your home than with our densest, 100% pure sheep wool?
Premium is our best sheep wool product: denser than Comfort insulation, offering improved heat and acoustic insulating qualities. Higher efficiency with a smaller depth of insulation required.
Below is a table listing the coverage of our 100mm-thick Premium insulation. For 150mm-thick Premium insulation, click here.

There’s a reason we’ve all been wearing wooly jumpers for years; the insulating qualities of sheep wool are second to none.
With 25% of heat escaping through the roof of a property, it is especially important to insulate this area. Laying wool in the loft creates a thermal barrier slowing the movement of hot air from, and cold air into, the home. This significantly lowers heating bills!
You don’t need to worry about the insulation making your home too hot in the summer – it can actually help to keep you cool. It helps keep your home at a moderate temperature by preventing warm air leaking in through your walls on hot days.
Whereas other wool insulating products on the market contain manmade fibres, glues and pesticides, our Optimal sheep wool insulation is 100% natural.
There are several reasons why sheep wool is such a good insulator:
1. The crimped fibres of sheep wool allow air to be trapped, slowing heat transfer.
2. Sheep wool is breathable so even when damp, its performance doesn’t drop and it even regulates moisture levels in the loft.
3. Sheep wool is extremely durable, so it can retain its thermal insulating qualities even when compressed, bent and stretched.
4. It is easier to work with than other insulating materials, as the soft wool can be handled easily into position. Because it’s natural, it causes no itchiness and no breathing difficulties.
Our Premium Sheep Wool insulation has a density of 20kg/m3, which is significantly higher than the mineral wool insulation from your local DIY store.
Using the thermal conductivity of this product (0.0359), you can work out either the thickness you require or the U-Value you will achieve. Simply divide the Thermal Conductivity by the thickness to work out the U-Value, or divide it by the U-Value you want to reach to work out the thickness required.
Our Premium Sheep Wool is the densest sheep wool we offer, offering slightly improved thermal and acoustic insulating properties. So if space is at a premium and you want to maximise energy savings while minimising the amount of material you use, then this 100% pure sheep wool insulation is for you!
Ignore young Henry below when he gets the thermal conductivity wrong – the Premium actually has a fantastic thermal conductivity of 0.0359W/mK!
