Wallrock KV600 Thermal Liner

Bit difficult to work with and need sharp scissors / knife to cut which it blunts over time.Also uses a lot of the specialist paste, but it sticks well consisting the weight!The room now gets warm with the central heating (too hot actually, which it’s never done before!). Heat is also retained for a while after the heating has knocked off, it never did this before and lost heat instantly.Expensive, but it does work!

If you live in an old house and you are thinking about insulation, this may just be all you will ever need. How do I describe this stuff. It's like a dense blanket on the inside and a tough wallpaper on the outside. The impact on room temperature is immediate. Buy the sharpest cutter you can get because your run of the mill wallpaper cutter would struggle. I have applied the liner in one room. Now I'm planning to apply it to the inside of my remaining outer walls.Regarding the negative comment about this liner not solving mould problem, I would take that with a pinch of salt. I am not a builder. But from my knowledge of mould the causes often have little to do with insulation. Poor air circulation leading to condensation, and the so called (some would say mythical) rising damp are more likely the primary causes. Cold wall act as the final link in many cases.

My external walls are not cold to touch anymore. Given that it is 1m wide, the paper is not easy to handle but it was OK. There was some minor creases at one edge of the role because of the weight when it is stored upright I think but all in all happy with the product and I am covering all external walls from inside.- Fixing wall cracks: I fixed some deep wall cracks with Ronseal Smooth Finish Exterior filler (grey) and some small ones with just excess glue.- Cleaning the walls: I wiped the walls with Dettol Anti Mould Spray and cleaned the wall surface and any black spots first, opened windows and aired the room.- Cutting: I measured and added extra length and then cut with scissors.- Gluing: I have used Wallrock Thermal Liner Adhesive mixed with Dryzone Anti-Mould Paint Additive to glue it to walls. You see the paper side, wall sees the fluffy side; glue on the fluffy side.- Marking the screw holes: I used sewing pins with heads through the paper as trying to make holes through the wet paper (softened by glue) were causing creases.- Trimming edges: I overlapped the ceiling mounding and wall skirting and with extra paper. I used a craft knife and renewed the tip often. I used Draper Straight Edge to push into corners and as the guide for the knife.- Smoothing: I used lots of old pieces of clothes and washed them after use before the glue on them dries.- Around the windows: I pre-cut pieces for some parts around window, unless they continued from the wall. I waited for the wall section to dry before folding into window sides.- Behind the radiators: I loosened the side-bolts just enough, lifted the radiators up and put them down horizontally, and tightened the bolts to stop leaking and removed the wall brackets. I put the radiators back after it dried.

Half way through papering the walls in an old uninsulated house the difference between the bare walls and the covered walls was staggering. Highly recommended. (Hard to hang though without another pair of hands because of the width and weight but with a second person easy as any other paper.)

What I wanted.

I used this thermal liner to insulate a couple of eaves cupboards. I anticipated that it would be unwieldy to use but the paper actually proved to be quite easy to apply in practice. Very pleased with the results.

The 1m wide option makes for difficult handling and the thickness means you need super sharp knife to cut cleanly, (I used scalpel blades). Even though this was wrapped in thick polythene and in its original box, you can see that the edges were damaged and, because of the thickness, the creases won't come out. This purchase was for the 3rd room I've used this insulation for, but the 1st time that the product was damaged. You can over-paper it, but I like the finish of this insulation. Be generous with the adhesive and, if you have to do some tricky cutting around objects, consider pasting down to just above the object, make the cuts, then paste the rest of the wall.

Certainly made a difference to the feel to the room. Not that easy to install, at 1 meter the roll is not that straight forward to handle and cutting to size is not straight forward without some creasing of the product on the wall. Easy to fill in gaps and the end result is fine.
