Sheeps wool can be used as insulation in a house to reduce heat and improve efficiency. Would you consider using sheeps wool insulation? Let’s evaluate this source of insulation.
Sheeps Wool Insulation: Can This Work to Reduce Heat?
Since time immemorial, sheep have been known to adapt to even the harshest of climatic conditions. Since sheep wool is a good insulator, it protects the sheep through any seasons whether cold, hot or dry.
Sheep’s wool insulation is made from sheep wool fibers. This can be a great energy efficiency play to improve the conditions in your home.
What is lambs wool as insulation?
Sheep wool has been used for ages to make insulation materials. The Mongolian nomads insulated the walls and floors of their homes using felted and woven sheep wool pads. There has been rising popularity in use of lamb wool for insulation with more people and societies adapting to its use. In Australia, Europe, and Canada, wool insulation is already popular, and the same is gaining traction in the USA.
Due to the waviness of the wool fiber, sheep wool forms tiny air sacks that trap air and consecutively store warmth in when its winter and out when it is summer.
Sheep wool is a natural raw material which is sustainable, biodegradable and can be recycled. It contains low embodied energy. Therefore, it is not hazardous to human health or the environment.
Unlike fiberglass insulation, lambs wool insulation does not need protection to install. Since sheep wool can absorb and release moisture, it acts as a useful insulating material. So, sheep wool can work to reduce heat. Let’s look at some of the features of sheep wool.
Essential Components to Sheeps Wool
Here are the essential elements of sheep wool:
- Wool is very safe since it does not readily burn in air. It needs a high oxygen concentration for combustion, more than is available in the air.
- Wool has valuable insulating properties that help in maintaining heat during winter and during summer, to keep heat out.
- Sheep’s wool insulation is safe to touch since it does not cause skin irritation. Therefore, there is no need for specialist clothing to install it.
- Wool is flexible, and therefore it is easily installed in homes.
- Wool fiber naturally absorbs and releases moisture without lowering its thermal insulating properties. It has the advantage of preventing dampness build.
- Sheep wool is a natural product produced by sheep every year and therefore, it doesn’t have costs of production.
- It is cheap and is affordable.
To better understand sheep’s wool insulation basics, let’s look at some of the pros and cons of using sheep wool Insulation.

Sheep Wool Insulation Advantages
Here are the pros of using sheeps wool as insulation.
Sheep Wool Helps Increase Energy Efficiency
One of the best ways to increase energy efficiency at home is through insulation. Natural wool insulation is a sustainable and green method of insulating your property. Lamb wool insulation can be used anywhere in your home, on the floor or even at the attic to keep your home warm during the winter and cooler during the summer season.
Sheep Wool Helps Reduce Energy Costs
Due to the ever-rising energy prices, people are looking towards long-term home improvements. Building insulation is a significant step toward energy consumption reduction, thermal efficiency, and reduction of energy costs.
When you insulate the attic space of a typical house, it can reduce energy bills significantly. Though you will need to consider the initial expense, sheep wool installation cost is far much lower compared to the energy bills you can incur if you opt not to insulate your building.
Sheep Wool Insulation is a Thermal and Electric Insulator
Another advantage of sheep wool is that it is an excellent thermal and electrical insulator. Sheep wool insulation is estimated to have a thermal conductivity of between 0.035 – 0.04 W/mK compared to standard mineral wool which usually has a thermal conductivity of 0.044W/mK.
Thermal conductivity is the rate in which heat passes from one side of a particular material through to the other side. It’s no wonder sheep can survive extreme weather conditions because the air pockets trap air which in turn helps the sheep to adapt to the varying climates.
Sheep Wool Controls Humidity
Besides being an insulator, Sheep wool can absorb moisture its weight and still retain its insulating ability. The sheep wool fiber usually is hygroscopic. It means that it can absorb water vapor and thus perfectly fits in the loft space where high levels of condensation occur. Therefore, lamb wool can help regulate temperatures in your house.
Sheep Wool Cleanses the Air
Wool is a natural protein. It is made up of some variety of amino acid chains typically 18 to be precise. Most of the amino acids have a reactive side chain, and thus sheep wool can absorb harmful and noxious gases and substances such as Sulphur Dioxide, Nitrogen Dioxide, and Formaldehydes.
It then neutralizes them through a process called Chemisorption. So, sheep’s wool insulation helps cleanse the air. This has health benefits too and creates a clean indoor environment.
Sheep Wool is Sustainable and Green
Sheep wool is natural and renewable. Therefore it is sustainable. Since sheep produce wool naturally, it would require only a portion of the energy to produce human-made wool equivalents. Sheep wool thus helps save energy.
Sheep Wool Offers Sound Insulation
Another benefit of sheep wool is the ability to absorb sound. Sheep wool is an ideal acoustic insulator that is gradually gaining traction in schools and offices to enhance concentration in the classroom and meetings.
Sheep Wool Insulation does not Burst into Flames
Due to the high nitrogen content of sheep wool, it doesn’t get burnt easily and it can self-extinguish as soon as the fire is put out. It is a great feature since it used in properties as wool will merely smolder and singe away instead of bursting into flame in the event there is fire. Sheep wool burns in temperatures more than 560°C.
Sheep Wool is Easy to Handle Compared to Other Types of Wool
Sheep wool is very easy to work with compared to both the glass wool and rock wool. The two kinds of wool cause a significant irritation when handling them with bare skin and can even damage your eyes and lungs.
Therefore, be sure to put on a mask and goggles during installation of either of these kinds of wool. Sheep wool insulation, on the other hand, is easy to handle and to work with. It is safe and harmless even if you lie on them and it would feel soft and fluffy.
Sheep Wool Disadvantages
These are some of the cons of using sheep wool as insulation.
- Despite being produced naturally, Sheep’s wool price is increasing rapidly due to the rising demand for wool for other purposes making it more expensive than the glass or mineral types of wool.
- Sheep wool also requires to be treated with chemicals. Therefore, it is not energy free to produce.
