We have a garage built in 1992, which sits right on two boundaries. Because of this it is a 'unique' roof design, which has caused weather tightness issues. (we are in the process of trying to sort this now). We have had to pull the mouldy gib off the internal walls, with a plan to replace them, as well as insulate and add some power points.
I applied for the property file from the council, and the two boundary walls are fire walls. Lined with 16mm Gib fyreline (that we have now removed)
Q1) Do we legally have to follow the architect plans from 1992 for the fire walls.. specifies 16mm fyreline, types of screws etc.
Q2) Do we have to follow current day building code for fire walls? I have information from the James Hardie website, specifying 10mm fyreline
Q3) Are there any restrictions on having electrical cables in fire walls?
We want to insulate the walls in the process, this will go through council consent, as we are doing a few other things to the garage as well.
