As one of the only dedicated UK suppliers of 100% natural loose fill sheep’s wool insulation, we don’t just sell insulation, this is our absolute specialty.
Modern synthetic insulations trap moisture and choke historic structures. We reject modern chemical techniques in favour of traditional, time-tested methods. Our wool breathes completely naturally because of our unique, chemical-free processing system. By allowing air and moisture to flow dynamically, Prowool protects the fabric of your building, making us the number one choice for sensitive restorations and eco-conscious DIY projects.
The Ultimate Solution for Heritage, Listed and Older Houses
Older houses built before 1919 were engineered fundamentally differently than modern properties. They lack modern damp proof courses and cavities. Instead, they rely on a "breathing" construction system where moisture enters the fabric of the building and naturally evaporates away.
- The Danger of Modern Synthetics: Introducing modern fiberglass, PIR board, or spray foam into a historic property acts like a plastic wrap. It traps ambient humidity inside the structural timbers and solid masonry, creating cold spots, interstitial condensation, and eventual structural dry rot.
- The Sheep's Wool Miracle: Sheep's wool is highly hygroscopic. It acts like a natural lung, dynamically absorbing up to 33% of its own weight in moisture without losing its thermal efficiency or feeling damp to the touch. When the external atmosphere dries out, the wool naturally releases the moisture back into the air.
- Architecturally Correct Protection: Prowool Insulation™ actively draws moisture away from ancient timber frames and lath and plaster ceilings, stabilizing the building's relative humidity and protecting historic features from structural decay.
- The Pre 1919 & Listed Buildings Exemption: Under UK Building Regulations (Part L), historic properties and traditional timber framed builds have explicit exemptions from modern insulation mandates. Conservation officers actively discourage modern synthetics because they trigger damp. Traditional loose sheep's wool is the legally preferred, architecturally correct material needed to keep heritage walls breathing.
Timber framing requires an insulation material that can shift, breathe, and adapt.
- Zero Air Gaps: Rigid foam insulation boards must be cut precisely, yet older timbers are rarely straight. This leaves micro gaps that cause severe thermal bridging and condensation points. Prowool Insulation™ loose fill naturally expands to pack perfectly into irregular framing gaps, eliminating cold spots entirely.
- Natural Wood Preservation: By regulating moisture levels directly against timber studs, our wool prevents moisture from sitting on the wood surface, extending the lifespan of your framing.
- Unbelievably Fast, Simple & Slump Free Netting technique Used world wide: Forget tedious measuring, precise cutting, and wrestling with rigid boards or itchy rolls. You simply staple up your netting, push the fluffy wool into the pocket, and move on cutting installation time in half. This time tested method has been used all over the world for hundreds of years and remains the standard practice in most other countries today. The micro-hooks of the insulation netting hold the wool in a perfect, uniform density. This allows you to achieve a consistent thickness across the entire wall or ceiling cavity, ensuring the wool stays securely lofted and never slumps or settles over time.
Whether you are preserving a 300 year old cottage or looking to slash the energy bills of a modern 21st century new build, Prowool Insulation is the ultimate loft top-up solution.
- Fills the Invisible Voids: In older lofts with uneven joists, or modern lofts packed with awkward wiring, pipes, and trusses, roll insulation leaves gaps. Prowool poured loose fill flows effortlessly into every hidden void, creating a seamless thermal blanket.
- Cool in Summer, Warm in Winter: Sheep's wool possesses a high specific heat capacity. This means it absorbs heat slowly during blazing summer days (keeping your upper floors beautifully cool) and releases it slowly at night, while trapping rising heat efficiently during freezing winters.
- Safe Over Existing Insulation: If your current loft has under performing fiberglass, you can safely pour Prowool straight on top as a clean, eco-friendly topping to instantly boost your home's R value without tearing out old materials.
Our wool is professionally graded, thoroughly washed, air dried, and opened for maximum loft. We pack every bag in Wales using high-quality fleece sourced directly from British hill farms.
- 100% Natural & Sustainable: Breathable, moisture regulating, and highly sound-absorbing.
- Zero Harsh Chemicals: Free from irritating fibres, chemical off gassing, and unpleasant additives. It is completely safe to install by hand without protective suits and totally non toxic to live around.
- Breathe Easy at Night: Sleep soundly knowing your home is insulated by 100% natural, chemical free British sheep's wool.
We believe in complete transparency so you can buy with total confidence:
- The Pre-1919 & Listed Buildings Exemption: Under UK Building Regulations (Part L), historic properties and traditional timber framed builds have explicit exemptions from modern insulation mandates. Conservation officers actively discourage modern synthetics because they trigger damp. Traditional loose sheep's wool is the legally preferred, architecturally correct material needed to keep heritage walls breathing.
- DIY & Outbuildings: For structures exempt from strict building controls including campervans, garden workshops, stables, glamping pods, and sheds you are legally free to choose any natural insulation you prefer.
- Our Non-BBA Disclaimer: Prowool is a raw, 100% natural agricultural product crafted for traditional heritage work and hands-on DIY. It is not currently BBA certified for modern commercial building regulation approvals. We offer an honest, chemical free alternative to synthetic commercial insulation.
