What are the environmental benefits to using Prowool Insulation™ Sheep’s Wool Products?
Prowool Insulation™ products, is a natural, renewable material—it’s biodegradable, and it stores carbon, since wool actually captures and holds CO2. Plus, it’s made from a waste byproduct of sheep farming, so it avoids synthetic, petroleum-based insulations. Similarly, raw horticultural fleece is fantastic for gardening—it's made from wool as well, so it helps retain soil moisture, provides insulation for plants, and is biodegradable—no plastic waste. So both offer a really low-impact, natural solution that supports healthier environments, both for building projects and in gardens.
What is Prowool Insulation™ Loose Sheep’s Wool Insulation?
Prowool Insulation™ Loose Sheep's Wool Insulation is basically just wool from sheep that's been processed so it’s fluffy and free-flowing, not pressed into sheets. You can blow it or pour it into spaces like walls or attics, and it helps keep your home warm, quiet, and it’s a natural, eco friendly option.
How does Prowool Insulation™ Loose Sheep’s Wool Insulation work for you?
Prowool Insulation™ Loose Sheep's Wool Insulation works by trapping air in between all the little fibers. So, when you blow it into your wall or loft, it fills those spaces, and that air acts as a thermal barrier. It also lets your home breathe, so it stays nice and comfortable, and it's really long lasting, too.
Is Prowool Insulation™ healthier/ more eco friendly than synthetic man made insulation?
Prowool Insulation™ Loose Sheep’s Wool Insulation is incredibly sustainable. It’s fully biodegradable and can last for decades—sometimes 50 to 100 years. Each kilogram of wool traps about 2 kilograms of carbon dioxide, making it better for the environment. It’s also healthier for you—being a natural material, it doesn’t off-gas like some synthetics do, and it helps balance moisture, improving indoor air quality. Plus, it’s easier to install safely. And what makes it even more sustainable is that sheep’s wool would otherwise be a byproduct of farming and would go to waste—so by using it, you’re giving that natural resource a second life.
How do I install Prowool Insulation™ Loose Sheep’s Wool Insulation in my loft/ in between joists?
When installing Prowool Insulation™ Loose Sheep's Wool Insulation in your loft or between joists, it’s important to keep it even and avoid clumping. You can apply it by hand, as all of our bags come in the right size to fit through a typical loft access hole. Just gently fluff it so it fills all spaces evenly. Be careful not to force it into corners, as clumps can form and lead to gaps where damp or cold spots might develop. Also, avoid covering any wires, pipes, flues, or vents. Aim to build the insulation up to the top of your joists—typically around 200 to 300 millimeters thick—so you get a well-balanced, effective layer. By keeping it even and ensuring no gaps, you’ll maximize its efficiency, while also protecting your home from damp and cold spots.
How do I install Prowool Insulation™ Loose Sheep’s Wool Insulation in my cavity walls?
To install Prowool Insulation™ Loose Sheep's Wool Insulation in cavity walls, first, you need to apply insulation netting to the studs or partitions. Use staples or tape to secure it firmly in place. Then, create a small access hole either at the top or under any noggins so you can fill the cavity from the bottom up to the top. Make sure not to overpack it—keep it fluffy and even—so the plasterboard or cladding stays flush and doesn't bow out. Also, avoid covering any wires, pipes, flues, or vents. You can apply it by hand for control, or you can use a machine if you prefer. Just ensure everything stays evenly distributed, so you avoid damp or cold spots and keep that thermal performance
How do I install Prowool Insulation Van Gapfiller™ Loose Sheep’s Wool Insulation in my van?
To install Prowool Insulation VanGuard™ Loose Sheep’s Wool Insulation in your van, first, you need to attach insulation netting across the entire area you plan to insulate—just like you would on studs in a wall. You can attach this netting either to timber battens or tape it directly onto your van panels. Then, create small access holes between each panel so you can fill from the bottom up to the top. Keep the wool fluffy—don’t overpack it—so that your chosen cladding stays flush and doesn’t bulge. Also, avoid covering any wires, pipes, flues, or vents. One big benefit of Prowool Insulation VanGuard™ is its loose nature, so it can fill tight corners where other insulations are too bulky. If you’re insulating the floor, you’ll need to create an artificial floor using battens, forming a joist-like system that you fill in between. Also, you may need a vapor barrier—apply it directly onto the metal of the van and tape it in place between the wool. You can apply all of this by hand, or use a machine for larger areas. Just remember, doing it correctly is crucial—follow these steps closely, and if you need further advice, get in touch with us using the contact details below.
Is Prowool Insulation™ Loose Sheep’s Wool Insulation pest resistant?
Prowool Insulation™ Loose Sheep’s Wool Insulation is a natural, biological product, and while it is naturally pest resistant, no insulation can offer 100% protection. Its performance depends on how it is installed and the conditions of the environment where it’s placed—including what it’s exposed to. We offer two fantastic ranges: our natural loose sheep’s wool insulation and our premium loose range. Both are excellent, but the premium range includes natural cedar extract for added protection. Just remember, because it’s a biological material, careful installation and good environmental conditions are key to its long-term performance.

Laying Prowool Insulation™ Loose Sheep’s Wool Insulation on top of pre-existing insulation?
Yes, you can install Prowool Insulation™ Loose Sheep's Wool Insulation on top of existing insulation. However, ensure that the space between the joists is visible so you don't risk stepping through the ceiling. Wear appropriate PPE, especially if the original insulation could be hazardous. Also, avoid covering any wires, pipes, flues, or vents. Distribute the wool evenly, and be sure to remove all packaging materials to avoid any issues down the line.
How do I install Prowool Insulation HortiFleece™ Raw Sheep’s Fleece For Horticulture?
Once you receive your bag of Prowool Insulation HortiFleece™ Raw Sheep's Fleece, determine the thickness based on your plant type, location, and weather conditions. For sheltered garden beds, a thinner layer may suffice, but for exposed tree plantings—like on windy hillsides—you’ll need a deeper layer to anchor it and retain moisture. Handle the fleece manually, wearing appropriate PPE, especially if lifting large amounts. Gently place the fleece by hand around each plant, and when watering, be sure to thoroughly wet both the plant area and the wool to keep it in place. This ensures the fleece stays anchored and supports moisture retention.
What are the benefits of using Prowool Insulation HortiFleece™ Raw Sheep Fleece For Horticulture?
Prowool Insulation HortiFleece™ Raw sheep's fleece is a game-changer for commercial tree planting, as well as for gardeners, arable farms, and hedging projects. For commercial planters, it saves time, money, and labor by bypassing the need for complex land prep. It’s also a boon to the ecosystem—no harsh chemicals or costly licensed sprays are required. Sourced sustainably from UK farms, it’s biodegradable and rich in nutrients—releasing nitrogen, magnesium, and sulfur to boost plant growth. For gardeners, arable farmers, and hedging, it works wonders: you get a large volume, so it covers hills, hedges, or bulk planting easily. Crucially, where the fleece covers the ground, weed growth is minimal—no competing plants threaten your chosen tree or crop, allowing it to grow faster, stronger, and yield better results. And because it retains moisture, you water less often, while the wool slowly releases goodness into the soil. Gardeners, too, benefit—from vegetable patches to arable fields, it’s a rich, cost-effective, and sustainable option. Plus, it supports local wildlife—birds love using it for nests—and it bolsters the entire ecosystem. You can even adapt it—depending on your environment, like a windy mountain, you adjust the amount, and if needed, you can add your own pest deterrents. In every scenario, it’s a simple, natural, and powerful way to support your planting goals and protect the environment.

Believe it or not, 5 kilograms of wool goes a long way, and because the bags are compact, you can easily fit a bulk load onto a trailer or just carry them on your back.

How much Prowool Insulation HortiFleece™ Raw Sheep Fleece do I need for horticulture?
When deciding how much Prowool Insulation HortiFleece™ raw sheep’s fleece to use, it really depends on your plant, your environment, and the weather.

Just ensure it’s stable, and if you have any leftover, seal the bag tightly to keep it dry so you can use it again. In short, go with what suits your specific situation best.
