Thermal resistance and transmittance of the ECOBEST wall system were certified at the Laboratory of the Center for Renewable Energy Resources & Saving (CRES), under controlled conditions in a TDW-4240 guarded hot box.

The procedures for measuring heat transmittance and heat resistance follow the standards of EN ISO 8990, EN ISO 12567-1 and EN 1946-4 and are accredited by EN ISO / IEC 17025.

The calculations of the heat transmittance coefficient, U, were made according to the requirements of EN ISO 6946: 2007 "Building components and building elements - Thermal resistance and thermal transmittance - Calculation method".
