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.

Yup, its not going to burn in a hurry!

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!

Won't he need a waste disposal licence?

DARFC

I have an exemption, no 7 (annual renewal) spreading waste for the improvement of agricultural land.

Who let him in ;-) refugee from redundant newsgroup.

Now that's stretching the meaning of improvement.

Impending retirement? Best beloved wants him to be occupied and not under her feet?

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.

From a PIR MSDS found randomly on the web ...

"Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/or groundwater"

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:

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
