fitting extractor fan

[Blue Fox]

Hello all

Got the job to fit an extractor fan that I mentioned in a previous thread but the property is a fairly new ground floor flat which has a wooden structure then bricked on the outside how do I stand with fire barriers if I cut a hole in the plasterboard downstairs would it affect the fire barrier to the flats above or to the side never worked on one of these wooden frame flats that are bricked up outside

Normally the fire break would extend into the cavity on each floor.

When you drill to an external wall you are safe and not compromising the fire barriers.

This is very different if it was a staicase or adjoining wall which will require exra fire precausions.

If in doubt you could use an intermittant mat cut to the shape of the fan, this will provide an exra barrier, and give a little extra protection.

Yes, must admit I was very careful that it didn't auto-correct mine to intermittent as well!
