So what did they use before asbestos for loose fill insulation

[Lawrence]

A thought that crossed my mind. After looking up what was used in Rayburn cookers and all I can find is a reference to a letter that asbestos was never used for loose fill.

Was rockwool around?

Was fibreglass around?

Confusing isn't it - asbestos insulation is produced from mineral found in rock - so I guess that this would class as rock mineral.

I was assured that asbestos had never been used for loose fill by the Rayburn people - back then Rayburn was still the company, not just an Aga brand name.

AFAIK they used rockwool style stuff - when I rebuilt my old Rayburn in the late 70s I managed to get some Rocksil.

See

has been going since 1946 in various guises.

Don't know when Rayburns were first built, but I presume rock fibre insulation is an old product.

Aha -

states "The Rayburn was first developed as a cooker and water heater in the 1940s "

states "Health and safety research on rock and slag wool has been ongoing for nearly 70 years. " This implies that the product was around in the 1930s in significant enough quantities to justify H&S research.

So logically rock mineral fibre can have been used as insulation since the first Rayburn was built.

Now off to do some real work :-)

Neiher of those was, but other minerals were. Can't remember what they were tho.

It's on again, I'm sorry I haven't a clue started the latest series today. An earlier series is on Channel 7 -whatever that is.

Why is it £80 to watch free to view?

Vermiculite - how many times must I tell you :-).

[PJO]

Vermiculite ?

How do you spell that?

[Lawrence]

Seems like rockwool and fibreglass have been around a long time.

Rayburn (aga-rayburn) state that they have only ever used rockwool and fibreglass. I asked them about a 1960s rayburn Nr1.

Which, the hydrated phlogopite or the hydrated biotite one?

[The Natural Philosopher]

isn't that phlogophite?

I think that the real question here is whether the Makita hair-splitting tool is better than the PPPro one (with 3 year guarantee) or the Ferm equivalent.

Corded or battery.

Of course, eye protection and a mask shoudl always be worn...
