A Canadian Distributor for Bio-Based Materials
Beyond Sustainability
Cork, lime and clay doing modern jobs. Insulating, waterproofing and finishing Canadian homes, with third-party environmental declarations behind them.
Beyond Sustainability
Sustainability you can check
Every environmental claim on this site traces to something checkable: a declaration, a data sheet or a test report. Diasen publishes independently verified Environmental Product Declarations, the same documents architects file for LEED, WELL and Passive House projects. When we say a material is bio-based, we can name what it is made of.
- Cork harvested from living oaks. The bark regrows for the next cycle.
- Lime that cures by reabsorbing carbon dioxide from the air
- Independently verified Environmental Product Declarations, published and hosted here
- Systems that renovate over existing tile and concrete, with no tear-out
What We Stand On
Six claims, each with a document behind it
From Living Systems
Cork bark regrows after harvest; no tree is felled. Diathonite plasters pair that cork with lime, clay and diatomaceous earth.
Declared and Verified
An Environmental Product Declaration is a third-party audit of a material's footprint. Diasen publishes them, and we host the documents LEED, WELL and Passive House teams file.
Walls That Breathe
Vapour moves through lime and cork coatings instead of collecting behind them. Drier assemblies, fewer moisture problems, healthier rooms.
Renovation Without Demolition
Microcement goes over the tile that is already there, at 2 to 3 mm. The old floor stays in place and out of the landfill.
Certified at the Source
Diasen has made these materials in Italy since 1985. A certified B Corporation, running ISO 9001, 14001 and 45001.
Water-Based, Low-VOC
Water-based sealers and paints, with low-VOC and indoor-air ratings carried on each product's data sheet.
