The research concerns the analysis of the influence of
thermal insulation upon the out coming thermo-technical
parameters with reference to three ways of positioning the
thermally insulating layer, namely: locally along the
height of the concrete girdle, outside the wall all along its
height and on the inner side of the outer wall, between the
The thermo-technical parameters determined in our study
refer to the linear heat transfer coefficient , to the
temperature factor on the inner side fR si , calculated
according to SR EN ISO 10211/1-98 and Standard C
107/3-97, chapter 7, point 7.3.2 and the temperature factor
on the inner side f*
R si , calculated according to SR EN
ISO 10211/1-98 chapter 6, point 6.1.2 and the provisions
in Standard C 107/3-97, point 5, Annex J.
The research concerned more aspects, but the paper
presents only the analysis of the results reached for a 36.5
cm standard solid brick masonry wall, plastered on both
faces and a reinforced concrete floor with a 20 cm girdle,
over which a 5 cm thick cement mortar flooring was laid.
The results of the research are presented numerically in
tables and also graphically, isothermal surfaces, heat flow
surfaces and isothermal curves being plotted for one of
the cases chosen.
The study was carried out with the help of the two
dimensional software, PSIPLAN, derived from the
CIMPPLAN software, variant 2004, designed by Prof. Dr.
