Thermal wallpaper experience?

Hi all,
I am trying to work out if it's worth putting thermal wallpaper on my exterior lounge and bedroom walls. I have a dehumidifier and i'm installing new radiators throughout the flat, so damp/mould should no longer be a problem but I'm wondering if thermal wallpaper will help as a little extra (and worth the cost). Any experience / thoughts welcome. Thanks!

    It won't provide much, if anything, in terms of insulation. It should stop condensation forming on the wall, but it will also trap moisture behind it.

    Treasure the moments that you have. Savour them for as long as you can for they will never come back again.

    No actual experience, but my gut says that it will help, possibly quite significantly.

    Remember the 'good' ol' days when folk would sometimes line their walls with a 1/8th inch layer of expanded polystyrene foam? If you as much as farted too close to it, it would tear. I remember, as a kid, being in a relative's house and finding this stuff. Place your hand on it - and it felt genuinely 'warm' (as a wee kid, I thought it was somehow giving out warmth...). Place your hand on the bare wall - stone cold.

    That's a 1/8th inch layer of the cheapest exp foam poly.

    If stuff like 'Wallrock' is better than that (well, it's certainly stronger and safer), then I'd lay odds there will be a noticeable improvement. I'd certainly happily bet that it would transform condensation issues, for example.

    Needs sticking on with the correct stuff.

    New tech insulation can stop damp and decrease warmth loss by 75% if done as a part of the walls and floors (floating ) 
    Application and replastering needed though so not a cheap option, Worth it though we did our floor downstairs, 200% warmer

    I used it in a room that had two external wall, that were covered in mould.  The walls were much colder to the touch than other walls in the house. 

    Applied the thermal wallpaper using appropriate thermal paste (don't use wallpaper paste).  The walls were immediately warmer to the touch.  I had cleaned mould off before using the thermal wallpaper.  It never returned. It had before using exactly the same techniques.  Cost £100 ish. The wallpaper was £12.99 a roll.  Worth its weight in gold.

    The cold room became sleepable in (it hadn't been before even with central heating on, dehumidifier, windows open, I'd tried it all).  The literature that came with the paper said it was like applying another layer of concrete blocks.  My experience would agree with that.  Regardless of what others say of not seeing how that can happen.  It did.  

    Everyone told me it was 'lifestyle' condensation.  Lifestyle was the same as in other properties and same after installation.  No mould, no damp, no coldness once thermal paper had been installed.  I'm not working for any company selling thermal paper and I'm telling it as I experienced it.
  • I’ve just had k6000 installed and it seems to have made a small difference, the walls are better. It’s difficult to apply, the paste is ultra sticky and it’s difficult to cut so you might want someone to do it for you!

    You lined your walls with NVidia graphics cards? That's bound to make a huge difference, but it'll cost a fortune to run.

    Or, what is k6000?

    Thank you Deannagone,

    Can you please provide details or a link of what you used, and is it still efficient?

    We've used this in a box room with 2 external walls and it cured our mould/condensation problems.
