Crafted in Mid Wales, Prowool Insulation provides high performance, loose fill sheep's wool insulation tailored for timber frame structures, extensions, and heritage restorations. Sourced directly from our family farm and local agricultural partners, it offers a sustainable, low carbon alternative to synthetic fiberglass or plastic slabs. Old and new timber frames thrive on breathability. Our wool naturally absorbs and regulates moisture, preventing harmful condensation buildup and protecting structural wood from decay. Every batch is gently washed, treated with a protective borax solution to standard requirements, and entirely air dried to keep the natural fibers perfectly strong and undamaged by harsh industrial heat. We are a growing independent business committed to doing things right. We are currently collaborating with specialist consultants and UK-based testing laboratories to finalize official fire safety regulations and certifications, bringing traditional insulation into the modern era.
