Insulating Lining Paper

Insulating Lining Paper

Or simply, 4 mm of polystyrene, which has been lined with 1200 grade lining paper. Yes, this means that the lining paper is already glued on top of the polystyrene at the factory and all you need to do is put it up on the wall and either paint it or use a wallpaper of your choosing on top of it. Of course, you can purchase polystyrene in rolls and lining paper separately, but this means you’ll have put the polystyrene on the wall first and then line it with lining paper. Twice the time and twice the risk.

Below is an image, which I’m hoping will give you a good idea about the thickness of the Insulating Lining Paper. The thickness of any wallcoverings is quite important as it will have bearing on the approach you need to take when working around the fittings such as light switches etc.

Adhesive

You have to use a solvent free adhesive such as Wallrock Thermal Liner Adhesive. If you think you’d be saving yourself a few quid by using something else perhaps you need to rethink the whole job. Whilst I understand that everyone wants to get the job done as cost effectively as possible, you won’t be doing it when the Insulating Lining Paper starts coming off here and there and you have to start again.

Now, this is a very important part of the job. You can’t use the likes of Solvite All Purpose (or any other type similar to this) to stick the polystyrene to the wall. It’d be a bit like using Bostik Paper Glue to stick a brick to a wall. Perhaps slightly exaggerated, but not far from the truth. We’ll be talking to a wallcovering adhesive manufacturer soon to find out more about the art of adhesive making so, for now, take our word for it.

Insulation benefits

The manufacturer claims that 4 mm polystyrene has the same insulation effect as an 85 mm brick, 98 mm sandstone block and 262 mm concrete. We all know that polystyrene has been used as a insulating material for decades and it works.

Which way is up?

I think the image below explains everything you need to know when hanging the wallcovering on a wall. As with most wallcoverings, allow 24 hrs drying time. This will give you the time to spot any problems and fix them. Once you feel happy with the result you can emulsion paint it or use a wallpaper on top of it.

Two sides to Insulating Lining Paper

 

A small issue with using polystyrene backed wallcoverings is that once you dent the polystyrene it stays that way i.e. it won’t come back up to flat level. There’s no need to panic though. It’s not going to happen by just touching it. The dent below was made using a pencil and I had to apply a fair bit of pressure. Should it happen, just fill it in with a good quality filler.

    Can I apply your insulated lining paper directly onto an interior wall already papered with Anaglypta

    • Hi Douglas,

      In short, yes. You can apply Insulating Lining Paper over Anaglypta; however, there are a few things to consider first:

      1. Is Anaglypta stuck to the wall properly? If it isn’t and is peeling off in places, when you apply the Thermal Liner Adhesive to it (remember, you paste the wall to apply the Insulating Lining Paper) it’ll get wet and come off even more, which can cause the layer on top of it to slide off.

      2. How textured / raised is it? The reason for the question is that you need to have enough flat surface for the adhesive to bond with the Insulating Lining Paper and Anaglypta. As you know the polystyrene backing is flat and won’t mould itself around the raised elements the same way that Wallrock Thermal Liner would.

      3. I presume you want to save yourself some work and not remove the Anaglypta from the wall before applying the Insulating Lining Paper, which is fine. Obviously, should you have to remove the two layers in the future that would be double the work then… but tomorrow is tomorrow.

      I hope this is of help, but feel free to ask more questions.

  2. I have this on my living room walls with wallpaper over the top and was initally very pleased with the result. Unfortunatley I noticed ripples in my wallpaper about one/two months ago (decorating was done 3 months ago). My decorator came out to investigate and together we established that the polysterene is still firmly stuck to the wall but the grey lining and wallpaper is not. The grey top layer has come away from the polysterne which has caused the ripple effects and the wallpaper to loosen. Can you advise if this is a common problem or have I been very unfortunate and got a faulty batch? The wallpaper I have on is good quality Tiffany range.

    Thanks

    • Hi Amber,

      We’ve come across this problem before from time to time and it could be caused by a faulty batch, but it could be caused by the application as well. Question 1: what was the time gap between applying the insulating lining paper to the wall and applying the wallpaper onto the insulating lining paper? This is the most common issue we’ve come across and managed to replicate it in our tests using one roll and getting two different results if the wallpaper was applied before the adhesive on the wall managed to dry. As you most likely know the temperature (outside and that of the wall) will play a role here as well. Question 2: Are the ripples appearing in one particular place or all over? If you have any photos it’d be very helpful.
      Thanks

  3. Hi the decorator followed the instructions & left it for the required time, he was doing 2 reception rooms so it was at least 24 hours if not more before the wallpaper was applied.

    The ripples started in one area at the top and has now spread right across the top of one wall and is also happening at the top corner of another wall.

    Any ideas how to solve this problem? or can it even be fixed? The problem is trying to stick the paper without ripping my wallpaper!
    If the room was to be redecorated again i imagine that it would be a nightmare to get the polysterene off the wall plus the cost etc.

    • Hi Amber,
      A couple of options: Try to apply good quality ‘ready-mix’ adhesive to where it’s coming off. If you apply adhesive to the liner (originally stuck to the polystyrene) and let it soak up the adhesive hopefully it’ll make the wallpaper more pliable as well and make the whole job easier.

      If you were to remove the wallpaper (yep, you’d need to get new wallpaper) and the liner from the polystyrene and start from scratch, I don’t think you’d need to remove the polystyrene from the wall at all (I presume that’s stuck to the wall). However, you’d need to line the polystyrene with paste-the-wall type of liner (you could use Wallrock Fibreliner) to ensure there are no further problems.

  4. So, I have 3 children (all under 10), would this be a suitable product to be installed on the hall stairs and landing?

    • Hi Robert,

      Hmmm, I’d say no. It’s more likely than not that one of them (or all 3 at the same time) will decide to either poke the wall with a pencil and find out that it produces white ‘pearls’ or just run into it with something. I think Wallrock Thermal Liner would be a much better product in this case, but it’s not made of steel either :)

    Would it be possible to overlay this onto ceiling tiles? to give a flat plaster finish

    • OnWall

      Hi Ian,

      I don’t see any reason why not, but to give it a plaster-like finish, you might need to consider using something like Wallrock Fibreliner Premium on top the Insulating Lining Paper. Are the tiles textured? The reason I’m asking is that the adhesive needs enough flat surface to grip to.

  6. What is the R value of this product?

    • Hi Steve,

      The manufacturer doesn’t provide the R value for their product as they’ve chosen to base the benefits on comparing it to: “4 mm polystyrene has the same insulation effect as an 85 mm brick, 98 mm sandstone block and 262 mm concrete.”. There are a number of websites where all sorts of figures are used, but can’t quote them here as they don’t relate directly to this product. Please be mindful of the difference between standard polystyrene (like this one) and extruded polystyrene with the latter providing better insulation. We offer Climapor Thermal Insulation Tiles that are made from the extruded polystyrene.

  8. Can this be applied directly to horsehair walls? I’ve already stripped the wallpaper. What kind of adhesive would I use?
    Thanx
    Arlene

    • Hi Arlene,

      You can, but I’d suggest that you size the wall first with some diluted adhesive. We suggest . You can try Graphite Insulating Lining Paper as well – better thermal insulation – .

  9. Hi there,
    How do you use this product on an alcove? I have two Windows which are set in the wall at 100ml and want to insulate right up to the window. How do I get a good finish on the edges of the inset without seeing a join? Do you use an edging tape?
    Many thanks,

  10. Hello,
    I have a cottage which has an upstairs bedroom with old wooden tongue and groove on the angled walls and cieling. Insulation was provided between the T&G 20 years ago when the slates were removed and felted.

    The tenant says the room has draughts because the T&G is old and air is coming in at several locations, making the room cold for use as a bedroom.

    If I was to get the insulating lining paper , could you clarify the following :-
    – What type of adhesive could be use to fix to the T&G which had been varnished ?
    - Could you apply two layers and what type of adhesive could be used?
    - Where can I buy the insulated /lined rolls and adhesive ?
    - any other ideas on how to block the draughts?

    Rob

    • Hi Rob,

      Please note that working wallcoverings on a ceiling is more difficult, but I’m sure you’ve worked that out already.

      - you need to use Wallrock Thermal Liner Adhesive; however, you might need to sand the varnish off to allow for the adhesive to bond well with the surface. You’d need to size it as well.
      - yes, you can apply two layers and the same adhesive would apply
      - you can buy Red Label or Graphite Insulating Lining paper at coveryourwall.co.uk – please follow this link: http://www.coveryourwall.co.uk/thermal-room-insulation-liners/polystyrene-insulation-lining-paper/

      As for the last question, I really won’t know how to advise on this from this side of the computer as one needs to consider where the drought is coming from and this needs a hands-on inspection.

    Can I use the 2mm insulated lining paper on top of metallic wallpaper?

    • Hi Janet,

      I think it would be safer to remove the wallpaper safe. I’m not sure how this metallic wallpaper is made, but immediate concern is that the adhesive paste might not stick to it properly.
