Muratura portante interna Gasbeton® Sysmic (λ=0,13 W/mK) - Finiture

STRATIGRAPHY: 

Aerated autoclaved cellular concrete (AAC) GASBETON Sysmic system eliminates the supporting structure, for the benefit of execution speed and construction costs. At the same time, it avoids vertical thermal bridges which, together with the low thermal conductivity of cellular concrete, contribute to reducing the building's energy needs for heating or cooling. The GASBETON Sysmic infilling system is formed by the following stratigraphy:
(external)
• 2 mm silicate colored silicate / siloxane
• 5 mm skim plaster with “Multiraso esterni” and glass fiber mesh “rete da intonaco GASBETON”
• 15 mm “Multicem” 
• GASBETON blocks
• 5 mm skim plaster with Incollarasa and glass fiber mesh “rete da intonaco GASBETON”
• 2 mm “Multiraso interni”
(indoor)
The masonry is also composed by a vertical stratigraphy, at the base there is mortar “GASBETON Multimalt”, above there are the wall row formed by the blocks. Inside the Revit file there is a second row of walls (on the right) which differs from the first due to the presence of the first hydrophobic wall row (IDRO block) with relative mortar “Malta ancorante IDRO” instead of the classic mortar “GASBETON Multimalt”. It is preferible to use these walls for infills placed on the screeds or on the foundations, since these walls inhibit the transmission of any rising damp from them.
