Air tightness of building structures and critical details
Vávra, Petr ; Tichomirov,, Vladimír (referee) ; Bečkovský, David (advisor)
In thesis is dealt with problematic of how the value of air permeability may be affected by properties for water vapour diffusion with regard to OSB material There were chosen two main brands of OSB at Czech trade market Two specimens of OSB with different thickness were chosen for each brand. As a first the specimens were tested for air tightness to work out a value of air permeability for each specimen. Afterwords, the testing was conducted for gaining properties of water vapour diffusion on each specimen. As a final assessment was analysed the impact of properties of water vapour diffusion on the air tightness for each specimen. The general meaning of gaining higher air tightness with higher water vapour resistance was proved . It was shown that with raising thickness is usually gotten higher value of water vapour diffusion resistance. However it could not mean getting high air tightness. The crucial parameter is the quality of the material for gaining higher resistance against water vapour diffusion as well as for higher airtightness.
Development of a new self-supporting insulation system with respect to dynamic stress
Machala, David ; Frajt, Daniel (referee) ; Drochytka, Rostislav (advisor)
This diploma thesis deals with suggestion of self-supporting insulating system that can be used for objects which insulating is more or less complicated. In this thesis are theoretically processed information about insulation systems while focus is on their structure, composition and principle of operation. Further, there is theoretically designed self-supporting insulating system which is practically built after theoretically composed testing for finding its basic properties. The most appropriate process of realization is formulated at the end after evaluation of the individual tests.
