Naturalia-BAU

What Naturalia-BAU does

Naturalia-Bau Srl is a privately held Italian distributor and system-specifier of natural building materials, headquartered in Merano (South Tyrol) since its founding around 1989. The company sells renewable-raw-material insulation (wood fiber, hemp fiber, cellulose, sheep wool), clay and lime finishing products, breathable waterproofing and airtightness membranes and tapes, and a proprietary anti-mold system (MUFFAWAY) to Italian residential and commercial construction markets. It packages these materials into coordinated, system-warranted stacks branded as NATURAROOF, NATURAWALL, NATURADIVIDER, NATURAFLOOR, plus the design/clay line (LEMIX, YOSIMA), and complements them with physical retail (Merano/Sinigo bioedilizia store), e-commerce (shop.naturalia-bau.it), and the NATURATOOL Pro self-service pricing platform with embedded technical consulting. Its customer base spans architects/engineers/designers (primary B2B), private homeowners, construction contractors, carpenters, and building-materials retailers, served by a field network of 24+ named regional technical consultants covering all Italian provinces. Naturalia-BAU generates revenue primarily through one-time material sales across its portfolio, supplemented by B2B technical consulting and a recurring/registered-account layer via NATURATOOL Pro, with dual Natureplus and Biosafe eco-certifications plus PEFC chain-of-custody certification anchoring its regulatory positioning in sustainable construction.
