Passive roofs opt

To achieve the passivhaus standard passive roofs need high levels of insulation, thermal bridges need to be eliminated and the structure itself needs to be airtight. The Irish standard (Part L 2011) for a traditional roof structure is 0.16 W/m2K; this is very close to the passivhaus standard (0.10 – 0.15 W/m2K) however it still does satisfy it.

To gain a deeper understanding of the passivhaus standard it is crucial to examine the difference between traditional Irish roof systems and Passive Roofs; again like before I have taken the two most common systems:

1. Block Cavity

2. Timber Frame
