Pulped paper loft insulation fire-safe?   
Good evening.

Two of my lofts (it's a funny house) are insulated with what
looks like old newspaper, kind of macerated or pulped to
make something vaguely like vermiculite. But fluffier.

I did a flammability test in the living room grate, and found
that it does burn, rather slowly (i.e. not vigorously like
ordinary paper), but then again, it did not refuse to burn
either.

Can anyone tell me if this stuff is safe? My guess is not,
and I should take it all out and replace it with something
else. But if anyone can give me an informed opinion,
I will be grateful.

It's probably reasonably safe. It should be very unlikely to be at the 
source of a fire anyway, and if there's a fire anywhere else in the 
house you should have got out (thanks to your smoke detectors) long 
before the flames reach the loft.

I'd be more worried if you had stuff like that under the stairs which 
form your means of escape.

If it's Bitvent,which is the only pulped paper insulation I know, it should
burn for a few seconds then extinguish the fire itself with the fumes.
However from your description it may not be this.  I would suggest you look
up Bitvent's address on the web and send them a sample to confirm if it is
their product or not.

Well, cables and junction boxes could form a source
of ignition in the roof space.

Good point, I do have some boxes etc. under the stairs.
I should put smoke detectors in those cupboards.


Thanks Owain,

keep it clear of recessed ceiling lights.

Possibly, but statistically unlikely compared to the major causes of 
fire i.e. smoking, chip pans, candles.

No, move the boxes :-) Especially if your consumer unit is there, and 
double especially if you have rewirable fuses. (Although if you have 
rewirable fuses maybe the wiring in your loft is manky enough to be a 
source of ignition...)
