The thermal insulating cork-based plaster
Diasen undertook the first series of tests on cork based plaster as early 1985. The aim of our research was to obtain a unique product that would have the best thermal, dehumidifying, sound absorbent and durability qualities (when exposed to cold, heat and salt) with easy applications.

All of the materials used in Diathonite production have a life-span of at least 100 years; recent archaeological findings have even brought to light remains of Roman houses dating back to as far as 2000 years ago, wich were insulated with corking. The diatomaceous and clay powders which form the basis of our product have accumulated in deposits for thousands of years on our planet. The natural hydraulic lime is also a binder characterized by high breathability.
|Cork: the decision to use cork was based on its ability to perform as a finished material, adaptable to, and therefore efficient for, new construction developments. This material is non-toxic, biologically pure, unalterable, impermeable, breathble, resistant, thermally inert, electrically neutral and no-deformable. It has a good mechanical resistance, low combustion speed and excellent acoustic characteristics.|
|Clay: it was the first construction material ever used. Within the Diathonite mix it adds consistency to the mortar. Further, as it is a porous and light aggregate it has an excellent thermal coefficient.|
|Diatomeic powder: this is a naturally occurring mineral, formed through the accumulation of organic material (cuttlebones, vegetation, etc.), in the ocean floor in prehistoric times. When the water subsided depostis were distributed in vrious parts of the earth. Due to its high level of porosity (85%) per volume, the diatomaceous powder can absorb liquid of up to one and a half time its weight, whilst remaining a completely dry aggregate.|
|Natural Hydraulic Lime: is a natural hydraulic binder, by high breathability; it is an excellent thermal insulator and in particular resists to thermal changes, has excellent adhesion to substrates.|
Polypropylene fibres: fibres are regarded as extremely important to construction. They prevent mortar from splitting so the thermally coated walls do not generate thermal bridges. They also bring a higher level of mechanical resistance to the plaster. The polypropylene fibres do not leave toxic residue. The small quantities used in the production of Diathonite do not affect the environmental soundness of the product and, in time, add complete stability.
Additives: the additives that we use are all totally environmentally sound. They are vegetable based and serve to amalgamate the mix, making it more malleable and easier to apply. They give rise to the formation of micro cells, which maintain a high level of permeability to water vapour and increase the thermal resistance of the binder.
