Wool Cords

Wool is a fantastic material that has been used for generations to seal windows and doors. Wool cords effectively block drafts and dust while still allowing the house to breathe. Unlike other textile fibers, wool is an elastic material that compresses in tight spaces and expands to fill gaps and cavities. Wool also repels moisture, whereas materials like cotton absorb it. This makes wool cords ideal for sealing windows and doors. Modern sealing strips are often made of rubber, which dries out and cracks over time, a problem avoided with wool sealing. Additionally, wool is an environmentally friendly option with a significantly longer lifespan.
