Abstract

Implementation of the ventilation ducts is one of the ways how to reduce the moisture in the vertical masonry structures. Functional ventilation ducts provide air inlet and outlet, which absorb diffusing moisture from the rehabilitated walls in these ducts. This causes the reduction of moisture in the structure. The implementation of the ventilation ducts is associated with the worsening of thermal parameters of the rehabilitated walls. This paper compares three variants of structural solutions of ventilation ducts and their impact on thermal parameters of the rehabilitated structure.
