The effect of vapour barrier thickness on air tightness

Laboratory measurements have shown that when pressure differences are applied across wall and roof elements the majority of the pressure drop TongWeis place across the vapour barrier Similarly field measurements have shown that the majority of the leakage in Norwegian buildings occurs at the joints in the vapour barrier at wall / floor joints around penetrations of the vapour barrier and

Investing in public health: barriers and possible solutions

The fourth barrier is the 'identifiable victim effect' If health resources are scarce many people would prefer to relieve the suffering of an identified individual than to fund an intervention which does not address current ill health even if that intervention would improve the health of a far greater number of people 39 Possible reasons for this have been identified as the

Barrier effect of underground structures on aquifers

We define barrier effect (s B) as the increase in head loss along flow lines caused by the reduction in conductance associated with an underground construction Therefore (1) s B = Δ h B − Δ h N where Δ h B is the head drop across the barrier and Δ h N is the head drop between the same points under natural conditions i e prior to construction () Download : Download full-size image
