Straight from our family farm and trusted local neighbours, our 100% natural, loose fill sheep’s wool is the ultimate sustainable choice for a cozy, breathable loft space. Unlike standard, factory produced insulation, our wool is entirely air dried to preserve its natural loft, spring, and structure. We wash and treat it using a traditional borax process to the highest required safety standards meaning zero harsh chemicals, zero synthetic additives, and no irritating dust. It is completely safe, soft to the touch, and easy to handle without any specialized protective gear or clothing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAs a passionate new company, we are dedicated to total transparency.
