During his presentation, Engineer Tsonkov explained which are the seven main factors affecting the healthy conditions in home and how thermal insulation favors a pleasant climate and comfort in the home. Eng. Tsonkov provided useful information and explained how thermal insulation affects the movement of air in the room and how the cold external walls combined with the hot bodies of the heating devices lead to strong convection, which disturbs the comfort of the residents. Finally, eng. Tsonkov explained to the citizens which are the benefits of thermal insulation of homes, namely: optimal temperature in the premises; weak convection; optimal air humidity that prevents mold, energy saving, construction cost savings, good design and functionality and environmental protection.

The last presentation was led by Eng. Yordan Nikolov, executive director of the Bulgarian Association for Construction Insulation.

He presented the different types of thermal insulation materials and their parameters, and also paid attention to the common problems and mistakes in the implementation of thermal insulation works and emphasized the importance of the correct implementation of thermal and waterproof insulation during renovation of buildings. Eng. Nikolov presented practical examples of improperly implemented thermal insulation systems and gave recommendations for avoiding these mistakes, while explaining how properly laid thermal insulation can prevent future problems such as moisture, mold and compromising the building’s facade.
