| 摘要 |
<p>The invention relates to a theory relating to the prevention of the condensation water in a built enclosure, where there is a significant vapour temperature and pressure difference in a material or a thermoinsulating assembly, the inside heat meeting the outside heat deficit or vice-versa, in the thermal insulation interval. According to the invention, the principle consists in that, in order to eliminate the condensation water, the heat flow has to convert the heat deficit into a thermoinsulating material/assembly (5) without diffusion into vapour or any air flow which transports hot vapours towards cold areas (2 and 3), the thermal insulation applied to an envelope wall with characteristics of permeability to water/air/vapour being configured as a vapour-impermeable insulation (IIV) or non-permissive thermoinsulating assembly (AI-NP).</p> |
