Ventilation for render carrier boards

[Solo Stavrou]

Can anyone tell me where the fire stop socks are meant to be fitted between the carrier board and sips panel as there is meant to be ventilation at the top and bottom.

This seems an impossible task ?

A very good point.  There is often a very vague spec when it comes to this.  You can get intumescent fire barriers that you attach to the panel and in the event of fire it will swell and stop the flame.  I expect they get purchased and correctly detailed and installed about 2% of the time.

 

Make sure you close the cavity around window openings (with timber or Rockwool) as this is an obvious place for fire to get from the cavity to the inside or vice versa.
