Diathonite Evolution


Diathonite Evolution is a natural eco-friendly premixed plaster, totally cement-free, made with pure natural hydraulic lime NHL 3.5, cork, clay, diatomaceous earth and reinforcing fibres. 

This product has the best lambda value and therefore the best coefficient of thermal conductivity currently on the market for thermal coatings.

Thermal insulation is an essential aspect to guarantee energy saving and high living comfort of buildings. In this system the insulation material is applied to the whole outer surface of the building, just like a protective coating on the entire structure.

Diathonite Evolution, a cork-based thermal plaster, enables you to easily and naturally create naturally high performance thermal insulation.
