Co to jest?

Eco- friendly insulation materials are defined by their lown environmental footprint, renovability, recyclability, and non-toxic composition. Unlike conventional options - such as fiberglass, mineral wool, or extruded polystyrene (XPS) - these materials prioritize resource efficiency andd ocupant safety. They are typically categorized into three groups: natural fibrous materials, recycled- content products, and bio- based foams.
