DIY Wool Insulation for Eco-Friendly Homes

Imagine insulating your home with the same cozy material that keeps a sheep warm on a frosty mountainside. It sounds a bit like a fairy tale – a house in sheep’s clothing – but DIY wool insulation is very real and increasingly popular among eco-conscious builders. Why are people wrapping their homes in wool? For starters, wool offers a trifecta of benefits that few modern materials can match: excellent thermal insulation, natural moisture regulation, and a sustainability profile that would make Mother Nature proud. Think about it: sheep thrive in both cold and hot climates, all thanks to their woolly coats trapping heat in winter and shedding it in summer. Those same properties carry over when wool is used in your walls or attic. The crimped wool fibers form millions of tiny air pockets that trap air and slow down heat transfer, which is exactly what you want from an insulator. In fact, sheep’s wool insulation achieves R-values around 3.5 to 4.0 per inch – very comparable to conventional fiberglass batts. That means it can keep your home just as snug, all while being nature’s original high-tech fabric. And wool doesn’t just insulate against temperature swings; it also naturally manages moisture. It can absorb up to about 30% of its weight in water vapor without even feeling damp. On a clammy day, wool will quietly suck up excess humidity from your indoor air, then release it later when the air dries out. The result is a steadier, more comfortable indoor climate – as if your house itself were breathing and keeping sweat off its brow. Fewer humidity spikes mean less condensation, which translates to reduced risk of mold or mildew. Who would have thought that old-fashioned sheep fuzz could outperform some fancy modern materials in maintaining a healthy, dry home?

Beyond thermal and moisture perks, wool insulation brings a bundle of other advantages. Fire resistance? Check. Wool is inherently flame-resistant and doesn’t easily ignite – it will literally self-extinguish once a flame source is removed. Thanks to its high keratin protein and moisture content, you’d have to heat it to about 560–593 °C (over 1,000 °F) before it catches fire. Even then, it tends to smolder and singe rather than bursting into flames. (No “roasted lamb” jokes, please!) This gives wool a big safety edge; it won’t act like a wick spreading fire through your walls, and it doesn’t release the toxic smoke that some synthetics do when they burn. Soundproofing? Wool’s got that covered too. The dense, curly fibers are superb at dampening noise. Install wool in your walls or ceiling and you’ll notice a hush – it’s like your home is wearing noise-canceling headphones. Builders have found that wool insulation significantly reduces unwanted noise transmission, making it popular in schools and offices where quiet is golden. If you live on a busy street or have raucous neighbors (or kids!), wrapping your abode in wool can help turn down the volume of the outside world. Health benefits? Perhaps one of wool’s biggest wins is what it doesn’t do: it doesn’t itch, shed microfibers, or off-gas nasty chemicals into your home. Anyone who’s handled fiberglass knows the misery of those prickly particles – not to mention the formaldehyde binders and other VOCs many synthetic insulations contain. Wool, by contrast, is a natural protein fiber and contains no added formaldehyde; in fact, it can actively absorb indoor air pollutants like formaldehyde, nitrogen oxides, and sulfur dioxide, neutralizing them through a chemical bonding process. Your insulation becomes an air purifier of sorts. People with allergies or asthma often report that wool insulation feels safer and more comfortable for them. One major supplier notes that wool helps improve indoor air quality by bonding with harmful chemicals rather than releasing them. And unlike fiberglass or mineral wool, sheep’s wool is easy on the skin and lungs – you could rub your face in it and it’s just…well, woolly. (Some installers literally joke they could take a nap in the stuff.) This hypoallergenic, non-toxic nature means you typically don’t need heavy protective gear to install wool – no respirator, no hazmat suit. One homeowner in the UK was delighted to find “no such worry of having to wear masks” when fitting wool, saying they really enjoyed the hands-on process. That’s a stark contrast to handling fiberglass, where you’re usually itching and coughing despite all the PPE.

So, wool insulation clearly has a lot going for it in theory – but how do you actually get wool, and is it really eco-friendly through and through? The wool used for insulation is usually sustainably sourced from sheep (don’t worry, no sheep are harmed – they’re just getting a haircut). In many cases it’s the coarse “waste wool” that isn’t suitable for textiles, so using it in insulation gives a purpose to a natural material that might otherwise be thrown away. This adds to wool’s green credentials: it’s renewable (sheep regrow it every year), and biodegradable too. When it finally does wear out decades down the line, it can compost back into soil instead of lingering in a landfill for centuries. Ethical consumers will want to ensure the wool comes from humane, cruelty-free farms – thankfully, many insulation companies follow standards like the Responsible Wool Standard to ensure sheep are raised and sheared ethically. It’s worth doing a bit of research on your supplier: look for transparent sourcing information and certifications if available. On the production side, wool insulation typically requires far less energy to produce than synthetic insulation. One industry source notes that turning sheep wool into insulation uses under 15% of the energy needed to produce the equivalent amount of fiberglass insulation. Lower energy means a lower carbon footprint. Combine that with wool’s ability to reduce your home’s heating and cooling needs, and you have a material that’s eco-friendly both in creation and in use. From an environmental standpoint, it’s about as close to guilt-free as insulation gets.

Now, let’s say you’re ready to dive in and insulate your home with wool – how do you go about it? Is this a doable DIY project or a recipe for frustration? Good news: installing wool insulation is very DIY-friendly compared to many other materials. Remember, no itching and sneezing, which already makes the job more pleasant. You won’t be wrestling with unwieldy rolls of fiberglass candy floss or spraying toxic foam soup; instead, wool often comes in handy batts or loose fill that’s easy to manipulate. Depending on what form you get your wool in (pre-made insulation batts, loose wool from a supplier, or even raw fleece if you’re really adventurous), the installation steps will vary a bit. Let’s walk through a basic DIY game plan for a wool-insulated wall or attic, no subheadings needed – just a natural flow from one step to the next:

1. Gather Your Materials and Tools. First, source your wool insulation. Most DIYers will purchase ready-to-install sheep wool batts or rolls; these look a bit like the familiar fiberglass batts, but denser and way softer (you might be tempted to make a pillow out of one). You could also get loose-fill sheep wool, which is great for attics or irregular spaces – it often comes compressed in bags, and floofs up when opened. If you live on a farm or have a wool source, you can use raw wool from sheep, but be prepared to skirt (remove debris), wash, and treat it (more on that in a moment). Besides the insulation itself, grab a tape measure, a utility knife or sharp scissors (for cutting batts to size), and a staple gun with staples if you’ll need to attach any support mesh or vapor-permeable barrier. It’s also smart to have a dust mask or respirator handy for any stray dust, and gloves if you want – though with wool, these are optional for comfort rather than safety. And of course, don’t forget basic safety: a long-sleeve shirt, pants, and good lighting in your work area.

2. Prep the Space. Before stuffing those cavities with wooly goodness, ensure your walls or attic are ready. Seal up any major air leaks or gaps in the framing with caulk or expanding foam (around pipes, wiring holes, etc.) – wool will handle small cracks by molding into them, but it’s not an air barrier, so you want to stop big drafts beforehand. Check for any existing moisture issues: if a roof leak or wall leak is present, fix that first. The beauty of wool is that it tolerates moisture, but you don’t want to leave it sopping wet chronically. Also, if you’re removing old insulation (especially nasty stuff like asbestos or old fiberglass), take proper precautions and clean the space. Once the area is cleaned, dry, and leak-free, you’re ready to roll (or batt, as it were).

3. Measure Twice, Cut Once (if needed). Measure the dimensions of the cavities you’re insulating – the distance between studs or joists and the height of the space. Most commercial wool batts come pre-cut to standard stud widths (e.g. 16” or 24” on-center framing) and in thicknesses for typical wall depths. If you’re lucky, the pieces will just friction-fit right into your wall bays. If a piece is too large, use your utility knife to trim it down; if it’s slightly small, you can fluff it out a bit or tuck pieces together to fill the gap (wool batts can be a bit forgiving as they’re pliable). The key is to fill the space completely but without over-compressing the wool. You want it to stay lofty because the air trapped in those fibers is what insulates. Pressing it too tightly can squeeze out that air and reduce performance. So, cut gently, and err on the side of a snug fit rather than a jammed one.

4. Install the Wool – Stuff, Don’t Stomp. Now for the fun part: putting the wool in place. If you have batts or rolls, simply insert them into the stud bays or joist spaces. Start at one end and work to the other, making sure the material expands to fill the width. If you’re insulating above your head (like a ceiling or attic roof), you might use a few staples or support netting to hold the batts up until you attach drywall or interior cladding. With loose wool, you have a couple of options: hand-stuffing or blowing. Hand-stuffing is straightforward – grab clumps of wool and pack them into the cavity. A little trick: use a stick or broom handle to gently push wool into far corners, and to ensure it’s evenly distributed. Our friends at a Texas renovation found that even using an ordinary leaf blower as an improvised blowing machine worked great for loose wool: they stapled mesh over open wall studs and blew wool behind it, which quickly filled the cavities. The crew was pleasantly surprised at how easy (and even enjoyable) this process was – “no itching reported” they noted, somewhat amazed. Whichever method, aim for consistent density. Do not stomp it down or overly compress it; just fill until the space is nicely full. The wool’s springiness will help it stay put. Pat it like a fluffy cloud to make sure there are no voids or large air gaps, especially around edges or corners. Unlike rigid foam, wool can tuck into uneven spots, so take advantage of that by teasing and tucking as needed.

5. Address Vapor Barrier (or Not). One big difference with wool is its “breathability.” In many builds, you’d now staple a plastic vapor barrier over fiberglass insulation. But with wool, part of its charm is that it manages moisture on its own and is vapor-permeable. You generally want to avoid a completely impermeable plastic barrier which could trap moisture in the wool. Instead, if your building code or climate calls for it, use a vapor-open barrier or membrane. These are sometimes called “smart” vapor retarders – they let moisture escape while still blocking wind. The idea is to allow the wool and wall to dry out if they ever get a bit damp. Think of it like a GORE-TEX jacket for your wall: keeping bulk water out but letting vapor pass. In a lot of cases, simply covering the wool with drywall (which itself has some vapor permeability) and a coat of paint is sufficient. Always check your local codes, but remember: walls need to dry, not just breathe. Trapping wool behind plastic sheeting would negate one of its greatest strengths (moisture regulation), so opt for a more breathable solution.

6. Button It Up. With wool in place, finish your wall or ceiling as usual – install drywall or interior paneling over it, sealing up any seams for air tightness. In an open attic, you can leave the wool exposed on the floor; just be careful walking around so you don’t compress it in high-traffic areas (you may want to lay planks or build a small platform if you need storage space on top of the wool in an attic). Clean up any stray tufts (although you might keep a bit for stuffing that drafty gap under a door – waste not!). Step back and admire your work. If it looks like your house grew a thick woolly sweater in its walls, you’ve done it right.

7. (Optional) Treating Raw Wool. If you went the hardcore route and sourced raw sheep fleece to save money or just because you can, there are a couple extra steps: washing and pest-proofing. Raw wool comes with lanolin (grease), dirt, maybe some straw, and the occasional whiff of barn. You’d need to wash and dry it thoroughly, and then treat it to deter pests like moths. A common DIY treatment is using a borax (borate) solution – basically soaking or spraying the cleaned wool with a borate salt solution and letting it dry. Borate is a natural mineral that is great at repelling insects and also adds fire resistance. In one DIY project, homesteaders sprayed their wool with borax and even tossed in dried lavender, finding that it helps keep moths away (plus it gives a lovely scent!). Commercial wool insulation is usually pre-treated with a similar insect repellant (one European standard is something called Thorlan IW, which bonds to the wool and wards off moths permanently). So if you’re buying insulation-grade wool, you shouldn’t need to do anything extra. But untreated wool absolutely needs this step – otherwise, you might be unintentionally running a wool moth farm in your walls, and that’s a nightmare no one wants. The good news is that once properly treated and installed, wool insulation is very resistant to pests and should last for decades without issues.

By now, you might be thinking: This sounds fantastic – why isn’t everyone doing this? What’s the catch? As with any material, there are pros and cons, and wool insulation does come with a few critical considerations and limitations to keep in mind. Let’s talk dollars and cents first. Wool insulation tends to cost more upfront than standard options. Estimates vary, but by many accounts you could pay about twice the price of fiberglass for sheep’s wool insulation. For example, one analysis pegged wool around $2.40 per square foot versus $1.20 for fiberglass of equivalent coverage. In practice, if fiberglass batts for your attic would cost $1,000, wool might be $2,000 or more. That’s not pocket change. The high cost is partly due to the still-small scale of the wool insulation industry and the processing involved (washing, treating, forming batts). However, it’s important to view this in the context of long-term value. Wool’s durability means it can perform well for many decades without needing replacement. It’s not uncommon for fiberglass to sag or compress over time (or get yucky and need removal), whereas properly installed wool can remain effective and springy for the life of the building. Wool’s ability to manage moisture also means your home’s structure might be better protected from rot and mold, potentially saving repair costs. And of course, there are the intangible savings of healthier indoor air and fewer itching incidents. Some experts suggest the ROI (return on investment) of wool insulation can be 100% or more – essentially paying for itself through energy savings and longevity. Additionally, if you factor in environmental costs or future disposal costs, wool comes out ahead. (Disposing of synthetic insulation can be costly or problematic, whereas wool at end-of-life is compostable – no hidden “ticking time bomb” disposal fees down the road.) Still, if you’re on a tight budget, the higher upfront price of wool might be a limiting factor.

Another challenge is availability and finding the right product. Unlike fiberglass, which you can find at any big-box hardware store, sheep wool insulation might not be sitting on the shelf of your local Home Depot (depending on where you live). You may need to order it from a specialty supplier, possibly overseas if none are local. This can mean higher shipping costs and longer lead times. Fortunately, companies like Havelock (USA), Thermafleece (UK), and others are expanding distribution, so it’s getting easier each year. It’s worth checking if any eco-building suppliers in your area stock wool insulation. The flip side of this coin is community support: when you buy wool insulation, you’re often supporting farmers and small businesses committed to sustainability, which has its own feel-good reward.

We also must address the pest and degradation concerns, because any time you mention “wool”, someone is bound to ask: But won’t the critters come? It’s a fair question – after all, moths famously eat wool sweaters. The reality: modern wool insulation is treated to resist pests, and when done right it is very effective. Moths, carpet beetles, and the like won’t munch on the wool because the treatment (often a borate or a more advanced proprietary solution) makes the fibers indigestible or toxic to them. One manufacturer even developed a biocide-free ionic treatment that permanently protects wool without traditional chemicals. So if you purchase quality insulation, you shouldn’t have moth issues. That said, if you use raw or untreated wool, you absolutely must treat it as described earlier – otherwise you could indeed attract insects. And what about bigger pests, like rodents? It turns out mice and rats don’t particularly want to nest in wool either. Sheep’s wool fiber is made of keratin (like hair), not plant material, so it’s not a food source for rodents – unlike, say, cellulose insulation which is treated paper (yummy starches). Manufacturers note that the texture of wool can even deter rodents because the fine fibers can get up their noses and are a pain for them to navigate, meaning they’re less likely to set up camp. Of course, no insulation is 100% rodent-proof – if critters are a big problem in your area, you still need to seal entry points. Mice can and will chew through many things (even fiberglass or foam), so wool isn’t a magic force field. But you’re not inviting them with wool any more than any other insulation, and perhaps even less so compared to food-based materials.

Moisture and ventilation considerations are another important aspect. Earlier we praised wool for handling moisture beautifully, and it does. However, you still have to design your assembly so that any moisture that does get in can get back out. Wool can hold a lot of water vapor, but eventually it will release it – you want that vapor to be able to escape to somewhere, lest it accumulate. That’s why, as mentioned, you’d use a vapor-open barrier strategy and ensure there’s some airflow or drying mechanism in places like attics. In a roof, for instance, you might still vent the roof deck above the wool to carry away any moisture wool releases. The good news is wool’s presence actually reduces the chance of condensation in the first place by buffering humidity swings. But builders need to pair wool with compatible materials (e.g. breathable wall sheathing or smart membranes) to fully capitalize on this. Another challenge occasionally mentioned is settling or compression over time. With loose-fill wool, if it’s not packed densely enough or supported, it might settle a few percent over many years (like any loose insulation can). And gravity is always at work on insulation in walls; poorly supported batts of any type can slump. The solution here is straightforward: install it correctly and use the right product. High-quality wool batts are mechanically bonded (needled/felted) to be springy and resist slumping. When professionally installed, manufacturers assure that wool will not “collapse” or lose its shape in the wall. One myth is that wool might rot if it stays damp – but wool’s natural resistance to mold means it typically will not rot as long as it can eventually dry. In fact, wool contains natural lanolin and proteins that inhibit mold growth, so even in high humidity it tends to fare better than plant-based insulations. Still, prolonged saturation (say from a leak) isn’t good for any material. If wool does ever get flooded, it should be removed, dried, cleaned (wool can actually be washed and re-installed if done carefully), and the source of water fixed. It can handle incidental moisture with ease, but it’s not meant to sit underwater indefinitely – fair enough.

A perhaps more philosophical downside: wool insulation is not 100% “pure” wool by the time it’s in your wall. To get those great fire and pest resistances, manufacturers typically add small amounts of chemicals like borates (or newer substitutes) to the wool. Boric acid and ammonium sulfate are common additives used to meet fire codes and pest control needs. While these are relatively mild as far as chemical additives go (borates are also used in cellulose insulation and even as a laundry detergent ingredient), they are still chemicals. Pure wool straight off a sheep would burn more easily and could attract insects, so treatments are a necessary compromise. The amounts are low and generally stable (not off-gassing significantly), but ultra-natural living purists should be aware that their “natural” insulation isn’t just raw wool. From a practical standpoint, most people find this acceptable given the alternatives – it’s a far cry from bathing your house in formaldehyde or isocyanate foams. However, it’s a limit to the “naturalness” if that’s a primary motivator. Additionally, if you’re extremely sensitive to certain chemicals, you’d want to verify what exactly is used to treat the wool you buy. The good news is many companies are transparent about this, and some, like the Ionic Protect process, avoid added insecticides entirely.

Now, after weighing all these factors – cost, pests, fire, moisture, chemicals – you might wonder why someone would go through the trouble. This is where the discussion goes from the head to the heart. There is an emotional and psychological connection people feel with using natural materials in their homes. It’s hard to quantify, but very real. For centuries (even millennia), humans have insulated shelters with natural fibers: straw, wool, cotton, reeds, you name it. Only in the past 100 years did we pivot to mass-produced petrochemical insulations. Many homeowners describe a peace of mind knowing that the stuff behind their walls isn’t hazardous. It’s comforting to think that your house is aligned with nature, rather than at odds with it. With wool, you can literally sense the difference when you touch it or even smell it – high-quality wool insulation usually has no odor (it shouldn’t smell like a barn; thorough washing removes that, but it has a sort of neutral, earthy textile smell if anything. Certainly nothing harsh. Psychologically, using wool can make you feel like you’re taking better care of your family’s health, and of the planet. It’s a similar satisfaction as wearing organic cotton clothing or eating home-grown veggies – a simple, natural pleasure. Some people joke that having wool in the walls makes the home feel “cozy like a sweater” all year round. That might be placebo, but hey, if it makes you happy in your home, that’s a benefit too. There’s also the storytelling aspect: “Our insulation comes from sheep’s wool” is a conversation starter that often leads to intrigued smiles, whereas “it’s fiberglass” doesn’t have quite the same ring. I’ve heard homeowners proudly say that knowing their house is insulated with wool makes them feel warmer, as if the care that went into the material radiates back. While that might be psychological, it’s nonetheless an important part of the human side of building. We form relationships with our homes, and materials like wool create a positive, almost nurturing relationship. After all, wool has been associated with comfort (think warm blankets, soft sweaters) in our cultural consciousness forever – it’s no stretch to extend that comfort to our living spaces.

But you don’t have to take my poetic waxing as proof; consider some real-world testimonials from those who have taken the plunge. A homeowner in Ireland decided to insulate their loft with sheep wool and reported that it “completely changed the climate of the rooms”, making the spaces more comfortable immediately. They noted there were no issues installing even in a tight attic, and perhaps best of all, the “beautiful composition of the product was a joy to work with” – and it triggered no allergies while handling it. This speaks to both the physical comfort and the emotional joy of using a wholesome material. Another DIY enthusiast in Portugal took sustainability to the max by processing wool from their own sheep for insulation. They admitted it was a lot of work (several days of cleaning and treating fleece) but ultimately concluded it was “better than any insulation we have used in the past and more cost-effective” for their situation. With wool in their ceiling, they improved their home’s fire safety and soundproofing, and they loved that it wasn’t itchy and was environmentally friendly. They even crunched the numbers: 35 sheep’s wool provided about 10 m² of insulation at 10 cm thick, which would have cost them around €253 to buy, but only cost €35 (plus elbow grease) to produce themselves. Not everyone has a flock of sheep handy, of course, but it’s a compelling case of creative DIY recycling. On a more conventional note, builders who have tried wool often become converts. One professional remodeler in Texas was initially reluctant when a client asked for wool, but after installing it he said the crew “got a kick out of” the project and were surprised how easy and fast it went. They blew wool into walls of an old house with non-standard stud spacing (a task that would have been awkward with rigid batts) and it turned out to be quite forgiving. The builder highlighted that there was no itching and no lingering concerns about air quality that he would normally have with fiberglass or spray foam. That meant happier workers and a happy client with a green, healthy home. Another customer from England noted the relief of not having to wear a mask or gloves during installation and simply enjoying the process of putting in the wool – when was the last time someone enjoyed installing insulation? These anecdotes echo a common theme: people feel good about using wool, both physically and mentally. They trust it, and they like how their home atmosphere feels afterward. Some have even reported that their home smells fresher with wool insulation, likely due to wool absorbing any off-gassing that other materials in the home might produce (wool’s keratin can bind formaldehyde as mentioned earlier). It’s as if the walls themselves contribute to a cleaner environment. And if you need one more testimonial, just ask the three little pigs – if they could have insulated their brick house, I’d bet they’d choose a nice wool lining to finally take a peaceful nap without worrying about any huffs and puffs!

In conclusion, the future of home insulation may very well lie in looking to the past – embracing timeless natural materials like wool in new and innovative ways. DIY wool insulation exemplifies this trend: it merges traditional wisdom (wool keeps us warm, so why not our houses too?) with modern building science and sustainability goals. As we grapple with climate change and indoor health concerns, solutions that check multiple boxes – energy efficiency, low toxicity, renewability – are the need of the hour. Sheep’s wool hits a sweet spot in that regard. It challenges the long-held notion that high-tech chemical formulations are always superior; sometimes, a fluffy fiber that evolved on a sheep’s back can give those lab-made products a run for their money. Of course, wool isn’t going to completely take over the insulation market tomorrow. There are still situations where other materials might be more suitable (for instance, if you need an ultra-thin profile with very high R-value, closed-cell spray foam or aerogel might still win, and industrial scale projects might lean on cheaper materials). But as demand for green buildings rises, wool and other natural insulations like hemp fiber, cotton, and cellulose are stepping into the spotlight. We are already seeing more companies refining wool insulation – making it easier to install, addressing cost, and certifying it for building codes worldwide. One can imagine hybrid systems in the future: maybe panels that combine wool with other bio-based materials to boost performance, or wool insulation batts that come pre-treated with cutting-edge natural fire retardants so they can be used in even more applications. The trajectory is exciting and a bit heartwarming: we’re rediscovering what our ancestors likely knew, but with the added benefit of scientific validation.

For the DIY homeowner or builder reading this, the takeaway is empowering: you have options beyond the pink stuff and the spray foam. You can insulate your home in a way that aligns with your environmental values, that ensures your indoor air is clean, and that quite literally wraps your living space in comfort. And you can do it yourself with a material that’s pleasant to handle and deeply satisfying to work with. Yes, it might cost more upfront and you’ll need to source it thoughtfully, but the reward is a home that you can feel truly good about. If you’re passionate about sustainability, think of installing wool insulation as more than a home improvement task – it’s a statement. It’s you saying: I care about what’s in my walls and under my roof, and I want it to be safe, natural, and effective.

So, what’s next for you and your home? Perhaps it’s time to join the growing flock (pun absolutely intended) of homeowners who have decided to give wool a try. Maybe you start with a small project – say, insulating the garden shed or the attic crawlspace – to get a feel for it. Or go big and plan that eco-renovation you’ve been dreaming of. One thing is for sure: the first night after you’ve insulated with wool, when your home is quiet and comfortably warm, you might just find yourself sleeping a little sounder. Maybe it’s the improved temperature stability… or maybe it’s the peace of mind from knowing your house is insulated with a material that’s as gentle as a lullaby. The future of home insulation is wide open, but it’s looking a lot more green and natural. Don’t be surprised if one day wool insulation becomes a common standard for healthy, efficient homes. Until then, pioneers and DIYers like you are leading the way – proving that when it comes to making our homes truly sustainable, we don’t always need to invent something new. Sometimes, we just need to open the history books (or the barn doors) and rediscover solutions that were there all along. Ready to get started? If the idea of a home that’s literally comforted by nature appeals to you, take the leap. Do your research, source some quality wool, and roll up your sleeves. Your eco-friendly, wool-insulated dream home awaits – no sheepishness required.
