The Kingspan/Cellotex sort of thing I mean.
I have been looking on the internet about fire rating/combustability/
electrical wiring
Surprisingly little there, all a bit vague. Anyone on the panel know
about this topic?

Nothing technical but I have a lot of PIR foam offcuts to dump so I
tried putting a flame to a small piece.

There is a small amount of surface combustion and then the flame goes
out as char appears.

looks like a skip job:-(

The PIR foam itself usually has a class 0 fire rating (i.e. very good).
It is treated with flame retardants, and is self extinguishing.

out as char appears.

Yup, its not going to burn in a hurry!

There is no incompatibility with wiring in the way there is it EPS -
i.e. leaching plasticisers etc. However it will result in a dramatic
de-rating of maximum current if you enclose wiring in it.

I have a lot in the house. When I put it in, I understood there was no
problems firewise but I can't find anything on the internet about
this.

Re wiring, there are a couple of places where the lighting wire passes
through it but my loading is very low, lots of CFLs :-)

Jeezuz H.

Google "cellotex", first hit in the manufacturers website, "fire
rating" in the search box on the cellotex web site, "Advantages of
PIR" has a section of Fire performance.

Not difficult was it?

I've got a couple of bulk bags of this, still trying to decide whether to
risk feeding them through a chipper and then using as loose fill.

Do you want another one?:-)

My throat doesn't like the dust.
I needed some strips at 45mm and used the bandsaw to size it. Cloud of
dust every time I switch the m/c on now!

I have an exemption, no 7 (annual renewal) spreading waste for the

Umm..

Protection from frost? All those over wintered carrots.

Drainage improvement? Providing channels for the movement of water in
heavy soils.

Nesting materials for those avian species alert to the benefits of
reflective materials.

Yes. They don't actually give reasons.

My PIR scrap will end up in landfill.

The above comments are an *in house* attempt at jocularity within the
well regulated agricultural community:-)

That looks like a standard term that people copy and paste without
thinking.

For example: http://www.abbey-chemicals.co.uk/MSD...Water-MSDS.pdf
"EYE CONTACT
Promptly wash eyes with plenty of water while lifting the eye lids"

also
"ECOTOXICITY
There are no data on the ecotoxicity of this product."
(although that probably means "yes, we know it's harmless, you know
it's harmless, but no tests have been *on this product*")

Still a few years to go till then - unless something unforeseen happens -
though she does seem anxious already to find me things to do. When the
old suite was replaced I was told in no uncertain terms that the settee
had to be put in the garage loft ready for me to strip and refurbish 'as
a hobby when you retire'. A Beech frame and springs is what it stripped
down to and it now awaits my retirement as a DIY venture.

And with those last 3 words we get the thread onto topic rather than an
agricultural meander G
