Argatherm is the perfect thermal skim coat to achieve an authentic beautiful finish while maintaining the breathability of the wall/ceiling. It is designed to directly coat insultaing plasters (like Diathonite), avoiding heat dispersion and ensuring additional comfort elements. The final appearance is marked by a very slight roughness that is a distinctive feature of healthy living.
Argatherm is a lightened finishing smoothing compound with very fine expanded mineral fillers and a microporous internal structure that give the product exceptional lightness and important thermal insulation properties.
Where to use it
Argatherm is used internally or externally typically as a smoothing and finishing plaster over Diasen Diathonite thermal plasters. When applied over Diathonite, no other preparation of the surface is required. It is suitable for new builds and retrofit projects, including refurbishment of Heritage and Listed buildings. Argatherm is also compatible with other lime or cement based plasters (new or old) and Diasen’s Watstop Waterproofing System.
