I have just seen some 25mm quitled roof insulation, that says it
acheives 0.2 U value, its about the same price as 100mm kingspan,
which is also about the same U value.

Does it work ?

Its goona be much easier "materials handeling" than kingspan, and
thinner.

Neither product I have seen claims a BBA certificate. I am not sure a
BBA certificate means much, I have had products with certificates
fails, and the BBA arn't intereted ...

I too was interested in this last year. However I'm yet to be convinced.

The opposition don't agree.... see..

http://www.celotex.co.uk/pdf/Multi-foil_Bulletin.pdf

In response to this the company in question had some independent testing
done. Last December I asked them for details of how the test were done. They
sent me ...

http://makeashorterlink.com/?K6DA127EA

and

http://makeashorterlink.com/?R6EA537EA

However these do not describe the test in detail or how it's performed...

When I pressed them for details they said....

"Sorry, no, these are not for public release"

I have no idea if there have been any further developments dince Dec 04....

not bubblewrap is it?

Put it this way, you know insulation works by trapping air and keeping
it still... what is so vastly superior about this product compared to
glass wool? How exactly does 1" of it trap and keep still more air?

My thoughts exactly. It does have many (6-8) layers of silver foil,
which only deals with raidiant heat, not convected heat. It also uses
closed cell foam, which traps air better than glass wool, which is
very similar if not the same as some foam packaging you get.

The thing that really gets me thinking, is that you need to seal joins
between sheets, which makes it waterproof, but it also requires a
roofing felt above (25mm or more), and a vapor barror below (25 mm or
more), it also says in the insulation manual it needs 25mm above and
beolow, which make you think its also using the insulation of 50mm of
free air ..............

I also checked the performance report the vendor gave me, against the
people who he told me wrote it. I am not saying its fake, but the
specalisims of the authors are not insulation .............

There's been a lot of debate about this stuff and the methods used for
testing it. A lot of heat loss is by radiation and the multilayers of
foil separated by foam cut this rather dramatically. It's not cheap
but if your space is limited it could be a good option.
In the cryogenics field where vessels containing liquid nitrogen or
even colder substances need to be kept very insulated from the
environment, multifoil blankets consisting of 30 layers of foil and
paper per inch are used.

Yes.. What concerns me is that it does not seem possible
to get details of exactly how they do the testing of this stuff.
If they published the details of the method and the results it
would help me make up my mind. See my earlier post..

I used something which sounds similar to this on my loft room. It's called
Tri Iso Super 9 made by a French company called Actis.

The previous owners had boarded under the rafters and partially insulated
with polystyrene, but it was freezing in the winter. I didn't fancy ripping
it all out and installing celotex between the rafters, or installing celotex
under the rafters as that would have lost too much height. Then I found out
about the Tri Iso Super 9. I just stapled it to the existing plasterboard,
put battens on top, then more plasterboard. I've only lost about 3 inches of
height and the room is significantly warmer than before. To be fair, the
extra warmth is probably also due to better draught proofing and
repositioning the radiator.

I'm waiting for IMM to post his opinion, then we will know for sure.

More or less correct, see

Is it independently tested? If not then give it a miss. A lot of money for
bubble wrap.

But Tri Iso Super 9 made by a French company called Actis is not
bubble wrap. If you study it from the point of view of a theoretical
physisist you may conclude the manufacturer's claims are likely to be
correct.

Making your own with several layers of cooking foil and craft paper
would, of course, be much cheaper.

They claim the equiv of 200mm of Rockwoll in performance. No independent
test confirms this. A foam maker slags it but will not give full details of
their test. The jury is out. One organisation in Florida concluded that
radiant barriers are good for keeping heat out, in the attic. Other tests
in the US say is performs badly in cold climates. Any benefits are likely
to be draft proofing and a small amount of insulation from the bubble wrap.
Very expensive for so little. Beware!!!!

Making your own with several layers
of cooking foil and craft paper
would, of course, be much cheaper.

And probably as effective as the vastly overpriced Tri Iso.

If this stuff does what they say, It would have it in the loft tomorrow.

If the main transfer mode of the heat being lost is radiant then the stuff
works very well. But if the main loss mode is through convection it won't.

In a vacuum the first is true and I would imagine some satellites are
insulated with something like this.

Yes - those showed the stuff was dodgy. I was wondering if you had
something that showed it actually did work without bending the testing.

They supposedly tested two hot box houses in France. Apart from that little
else of the test. It is not independently tested and verified by a credible
organisation. Just wild claims.

The Celotext description of the NPL test showed that
it actually did work (for some value of work).

I think he would say give it a wide berth.

Price/performance. If it does what you want going by these Cellotex test,
then if the price is right, then it is fine. Currently it is "very"
expensive for what it is.

I'd guess it's as good as 200mm rockwool when used under the floor,
but only as good as 90mm rockwool when used in walls and as good as
60mm rockwool when used in ceilings.

OTOH for preventing solar gain in ceilings it would be as good as
200mm rockwool. All these would require ~25mm airgap either side.

Probably comes into it's own for insulating uneven or odd shaped gaps
and cavities, especially where a vapour barrier is also required or a
gap for ventilation.

cheers,
Pete.

That's where I used it (see previous post). It isn't except possibly for
reflecting heat from the underfloor heating upwards. When that's off it
does nothing.

All the above equivs. Is that just a guess by you?

A builder has just installed this stuff in the roofs of two new houses
next to me, interesting looking material, the builder hasn't spared any
expense on the rest of the build and had plenty of celotex on site which
he used for the floors. He's convinced that the quilt is the dogs gonads
as far as over the rafters type of insulation goes.

Bertie, has he any figures to prove the performance? Or does he just wave
his arms when explaining things?

Well he would wouldn't he. It's much easier for him to lay.
But he isn't paying for it's installation or for any future heating bills.
