Can anyone give me an idea of what sort of price I would pay for
100* 1.2*2.4*100mm sheets of polystyrene?

Or, what is the typical discount over 1.
Where would I be looking, builders merchants, or are there specialist
suppliers that do insulation?

Builders merchants will give you a price but flick through yellow pages and
look for packaging suppliers who do poly boxes etc. My B-i-L does everything
in poly and can probably do sheets at a decent price, I'll ask if you want?

I'm being stupid.

Ah.
I was getting hung up on assuming the first word was Build-something.
Many thanks.

I have recently being paying about £8 per sheet (8'x4') for the 50mm
jablite! I would guess that double the tickness may mean double the price.

What are you using it for, most specifications are now requiring the
horrably expensive urethane boards!

If you buy slight reject boards (www.secondsandco.co.uk) prices are nowhere
near as horrendous.

Everyone I know who has asked for quotes from them has only been offered
first class non-seconds boards at about the going rate.

Hmm. Got a whole lorry load from them a year ago at about half the going
rate and need some more soon. I'll see what happens.

I guess it's because they get stuff in fits and starts and the people I know
were just unlucky.

The tiles+battens+tar-paper on the roof of this house need replaced.
The boards beneath are sound.

I was considering replacing the tar-paper with 100mm polystyrene.
(with minor alterations to other stuff)

To create a warm roof, to enable the use of the attic as habitable space
at some point in the future.

The extra work is not that great, at this point.

Do you lay roofing felt on top of the polystyrene as well, or just tile
straight on top?

That's a problem.

If you could figure out the attachment of the battens securely (no more
nails?) then it might be an option to just tile straight on top of it,
if you can be sure that you've got the battens secure.

Simply cutting grooves for the tiles to fit in with a circular saw might
be an option with higher density foam.

Glue on a sheet of polystyrene, with battens pre-fixed, put the tiles on from
below, and repeat until finished.

However, subsequent work on the roof would be interesting, as you'd
practically require crawl-boards, and the risk of tearing a batten
off the polystyrene is probably fairly high.

I suspect sheets of 4mm exterior grade ply, with the battens fixed to that
may be an answer.

Vertical strips of wood under tar-paper, with the battens fixed to them may be
a better one.

Is there a better barrier than tar-paper?

Still at the early stages, just wondering if it's practical at the moment.
I don't see any show-stoppers.

First thing I'm doing is attaching ropes to the rafters, going through near
the top., as an extra backup.

I'm confident I could do it without, but I've been confident before.
Looking silly dangling at the end of a rope beats looking silly while falling
through the air.

Though the eaves are only 3-5m off the ground that's about 2.5-4.5m
further than I like to fall.

You don't want horizontal battens fixed to a solid roof. Any water
that gets through the primary covering (tiles, slates WHY) will be
trapped along the top edge of the battens and hasten the rot of their
rot.

On a boarded out roof you put the sarking on first, then vertical
battens and horizontals ones for the tiles on top. The verticals give
space for any penetrating water to run down and out into the gutter.

Simply cutting grooves for the tiles to fit in with a circular saw
might be an option with higher density foam.

And what are you going to nail then to? No nails and the first decent
blow will have the lot off...

Is there a better barrier than tar-paper?

Try the "gortex for houses" the name of which slips my mind ATM. It's
expensive but does breath unlike traditional felts and tar paper and
doesn't perish/rot either.

According to my Architect waht you do is this ................

from the rrafters you put on the insulation, then nail battons on top
of the orignal line of the rafters. Then goes in the felt, then the
cross battons which hold the tiles.

Now you go inside, and put more insulation between the rafters, then
you finish it off. This way the bottom of the rafters poke out into
the room, you you have exposed rafters.

Specialist insulation suppliers will be 20-25% cheaper than most BM's.

I think those sheets are about a fiver retail, so maybe 3 quid trade?
Can't remember.

An 8' x 4' sheet of polystyrene, 50 mm thick cost about £18
last week at Jewsons. If cost per unit volume is similar, then
double this thickness would be £36 !! Can't believe that either !!

Hi,

CW Berry are quite cheap for 100mm at £12.12+

http://www.cwberry.com/epb2.01/02-co...olystyrene.htm

If you are buying 100 sheets and cannot get it direct from the
manufacturer I'd expect they would do a good deal and get it delivered
direct.

cheers,
Pete.

Oopps. I misrtead youur sizes. I was thiking of the 1.2m x 600mm or
whatever it is 4x3 2 fiit, ou are talking 8x4 right? so multiply by at
leats 4, maybe 8, because 100mm is damned thick. somewhere in the 20
quid plus reguon.
