Air tightness and thermal bridging in buildings – Launceston
21 Nov 2019 at 1:00 pm - 2:30 pm AEDT$15
Presented by architect, Dr Detlev Geard, and builder and building thermal performance assessor, Paul Kleywegt.
Achieving air tight or leak free building structures and eliminating thermal bridging of the building fabric is imperative to achieving a successful thermally comfortable building. If there are gaps in the building structure then uncontrolled amounts of external air (hot or cold) can infiltrate the building. A thermal bridge in the building structure increases infiltration losses and may cause surface condensation or interstitial condensation in the building structure. This presentation shows of how we can design air tight buildings, and how we can eliminate thermal bridging within the building structure. In addition, a case study will be presented how a high degree of air tightness and the control of thermal bridging has been achieved at the recently completed Passive House at South Hobart
