Built on a background of hands-on lime and clay plastering, ECS began a decade ago, focusing on the natural treatment of damp, lime and clay plastering, and spraying cork insulation in southern Spain. Today, our small team (José, Antonio, and Clara) channels its experience into nationwide distributors of natural insulation. We bridge the gap between historic building restoration and modern NZEB standards, providing the advice and materials you need to build a healthy, energy-independent structure.
Our whole-house approach begins with a breathable “eco-envelope” made from natural materials such as Diasen solid wall renders, Steico wood fibre, carbon-negative hemp, and clay or lime plasters. To ensure these technical solutions are implemented perfectly, Bioreforma SL executes many of our projects in Andalusia in collaboration with our partner in Asturias. Together, we seamlessly integrate advanced climate control, including carbon mat heating, high-efficiency heat pumps, and smart ventilation, all powered by custom solar and battery systems.
Whether you are restoring a traditional Spanish ruin or building a state-of-the-art new home complete with luxury spa hardware, we ensure your project is flawlessly executed, remains damp-free, is highly efficient, and is fully self-sufficient if needed.
Our approach is simple: straight talking, stress-free, and absolutely zero bullshit, as we use tried-and-tested solutions.
We distribute our materials nationwide directly from Barcelona and Asturias. Please note our physical presence and distribution point in Cadiz is now closed due to ongoing logistical complexities. Please be assured that partners and clients will continue to receive project materials for the Cadiz region seamlessly through Bioreforma SL.
