Wallrock Themal Liner

No idea. But I'd have thought so.

If you can afford to lose an inch of space, tho', then go insulated plasterboard - the thinnest is only around 25mm total thickness, and will be FAR superior.

And probably cheaper.

 

Nope & I qoute the following from wallrock.

We do not recommend applying traditional lining paper (or wallpaper) over thermal liner, because lining paper expands when wet and shrinks when drying up (paper based products are dimensionally unstable), which can cause the corners of Wallrock Thermal Liner to be pulled off.

But, you can use Wallrock Fibre Liner,which allows not only painting but also the application of decorative wallpaper.

Insulated p'board is still much better.

 

And a good opportunity to do a bit of skimming

 

And cheaper.

 

Not cheaper as a 'whole' job from start to finish though also not as quick!

 

It looks like the stuff I replaced for someone recently. It didn't provide any noticeable difference to the room at all. Apparently it was quite expensive when you they had to buy the special adhesive and then the insulated layer product. The one I removed also had to be filled where the joints but up and didn't look good where it met the window reveal.

I replaced the whole lot with some insulated plasterboard (47mm on the walls and 27mm on the ceiling), Even I noticed the difference and went from working in a fleece to without one. Not sure which boards I fitted as they were unbranded but it wasn't polystyrene on the back but something more rigid than Celotex / Kingspan.

Wallrock adhesive is between £13 and £20 a tub and the rolls vary from £20 to £35. For an average room you are probably looking a 7 rolls and around 5 tubs. So you are looking at around £300+

Depending in on your wall surface and type of board, they can be fixed directly to the wall either with "Dot and Dab" or adhesive expanding foam - TS stock Siroflex which is really easy to use.

I put in some hammer fixings just to make sure

 

Wallrock Thermal Liner thickness 4mm, Insulated plasterboard thickness 47mm

 

Useless v effectiveness and didn't make much difference to the room. The lady of the house wanted the thicker board on the ceiling as well

 

My thoughts, Dave, and only my thoughts since I haven't used it - is that the Wallrock is probably as good as a 4mm layer of insulation can be. And that is, it'll certainly help a fair bit. Ie, it'll reduce condensation on that wall, will make that wall more pleasant to be close to, and will make the room a bit easier to warm.

Insulation is amazing stuff. Remember the days of 3mm polystyrene roll (I think you can still get it!)? I recall as a wee kid coming across this stuff on a relative's old house wall, and being fascinated by how 'warm' it felt when I placed my palm on it. I realise now that 'warm' means that it didn't conduct heat out off my skin...

So, that's a piddly 3mm layer of cheapo polystyrene. I'm hoping that Wallrock is better still than this, and it's - ooooh! - a whole mm thicker! So I'd fully expect it to make a noticeable difference to the pleasantness of being near that wall. So, fire ahead if you really must stick with this stuff.

I would also think that, once it's adhered properly on that wall, it ain't going to shift easily. So, follow the instructions carefully, and allow PLENTY of time to ensure the proper adhesive has fully set.

Once it has, I'd be astonished if normal paste and normal lining paper would lift it. I'd be bludy amazed. And bludy pished orf too...

 

But, I still think you should go 25mm insulted p'board...

That WILL definitely make a HUGE difference. And that I know. 'Cos I've used (slightly thicker) stuff on a single-skin wall and made that room genuinely cosy and a doddle to heat. In fact, the PC I am currently using - along with the heat from my festering brain - is enough to warm it...

 

I have used both, obviously 43mm will be much more effective than 4mm, fibre lining over the thermal lining is recommended due to minor movement (expansion/contraction) opening up the butt joints (very minor and irritating). If you ever use the polystyrene Warmaline you do have to cross line with lining paper and then a finishing paper cause that does move big time.
