RT Journal Article SR Electronic A1 Havířová, Zdeňka T1 A new aspects for project of subsequent thermal resistance extension at old-timer timbering constructions of wood JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 54 IS 2 SP 41 OP 52 DO 10.11118/actaun200654020041 UL https://acta.mendelu.cz/artkey/acu-200602-0005.php AB To ensure the reliability of subsequent thermal resistance extension at old-timer timbering constructions of wood for the period of their supposed service life a more profound analysis of construction is necessary from the aspect of a global thermal/technical evaluation. Service life of these buildings is dependent on temperature and moisture conditions in layers of the building cladding where the wood framework is built in. Temperature/moisture conditions or the corresponding equilibrium moisture content (EMC) of the construction show considerable effects on the functional reliability of the whole building from the viewpoint of mechanical resistance and stability, energy savings and thermal protection and hygiene, health and environment protection.
