About the Laboratory
The aim of the laboratory is to provide comprehensive measuring of physical parameters related to the transfer and accumulation of heat and moisture in building materials, constructions, and spaces. The equipment allows for laboratory measuring as well as for insitu measuring (at the construction site).
