Hi there,

What are your thoughts on this?

We are thinking of using it in a small room in the house which is
particularly cold and with little space for a larger radiator, there
are two external, solid and uninsulated walls.

Even if it makes just a little bit of difference it will be good, the
walls currently feel very cold in winter and you can feel cool air
running on the walls.

Cheers

When I moved into my current house it had this, or something very like
it, in several rooms. I can't say that I noticed the difference
though; the walls were still cold to the touch. I removed it in when I
redecorated.

If you don't mind losing a bit of room size, insulated plasterboard
might be a better option?

Hi,

I used the Wallrock thermal lining paper http://tinyurl.com/3md4xwc on a
good sized double bedroom, with 2 external walls (solid walls,
lathe&plaster ie no insulation), and the other 2 walls being mostly (a
good two thirds each) unheated stairs. So, it was a pretty cold room !

Anyway, have found it has made a difference, but am really not sure how
scientific that is ! When I was working in the room papering/painting I
felt it had made a big difference (again though, was i kidding myself on
?). Anyway, the walls are certainly not anywhere near as cold to the
touch anymore, so think it must be making a difference.

I used the wallrock thermal liner, then the fibreliner, then a blown
vinyl on top of that, then paint.

Would I use it again ? Hmmmmmmm it is very expensive. The room I did
was a bit of a one-off as it was by far the coldest room in the house.
Guess I'd need to think long and hard about the likely benefit versus
the cost to use it in any other rooms.

At a U value of 32, its almost completely useless.
4" of brick is already maybe a U value of 10 or less.
3mm of styrene foam is a U value of 10.

I used cork tiles in one chilly 4" solid brick extension I rented.

Made a lot of difference. Cork quite like polystyrene thermal wise.


Need a U value of less than 10 to start to make a difference on 4"
brick. Maybe less than 5 to make a difference on solid 9".

I used cork tiles in one chilly 4" solid brick extension I rented.

I did a cork lined room for my son back in the 70s. Unlike Proust, he
never did write a novel though.
IIRC it was much cheaper buying the stuff from a cork merchant rather
than as tiles.

?? no doubt there'll be a genuine Guild or Trade Association to help
one find them in your locale...

Thank you for all of the help and suggestions.

I am going to consider insulated plasterboard.

External solid walls have a U value of 2. The paper is quoted as
having a U value of 32. The combined U value will be 1/(1/2 + 1/32) =
1/(16/32 + 1/32) = 1/(17/32) = 32/17 = 1.88.

That's "a little bit of difference" ... but it's only 5%

A 27mm insulated plasterboard would bring it down to 0.88 (which is
50%). Personally, if you were going to redecorate the surface, I'd go
the whole hog. I am just finishing snagging our new bathroom which
has 100mm Pavadentro wood fibre insulation - that gives a U value of
~0.5. The alternative is 70mm Celotex + plasterboard, which gives a U
value of ~0.3
