When compared with other thermal plasters, the overall applied cost of Diathonite Thermactive and Diathonite Evolution is extremely competitive. This is because each has an exceptionally low thermal conductivity, meaning less material is required to reach a specific U value. Thermactive and Evolution also have excellent coverage rates of 2.6kg/ m2 and 3.7kg/ m2 per 10mm thickness (+/- 10% based on machine application on a level smooth wall). Drying times are quicker too: as a rule of thumb Diathonite plasters dry at a rate of 2mm per day compared with 1mm per day for conventional lime plaster. This speed of application results in a faster project turnaround and can produce significant savings.
