【 摘 要 】

Additional protection of aged buildings against rising moisture is one of the most important measures to ensure their long-time durability and sustainable user properties. One of the remediation methods is the ventilated wall (air cavity created by additional thin wall), located in the interior of the building but ventilated to the exterior. The aim of this remediation measure is to reduce the amount of rising water which increases moisture level in building walls (in case of malfunctioning or missing waterproofing layer). The paper presents innovative technical solution in this field. The technical solution relates to an internal ventilated segmental plinth, which is formed by an assembly of shaped boards with a thermal insulation layer applied to their back sides and being provided with side plates for their butt joining one next to the other alongside the inner side of the building maintained exterior wall. The boards form a continuous air cavity enabling intense diffusion of water vapor from the adjoining moist wall. This patented solution is very simple, low cost and can be done from environmentally friendly materials.
