“An extremely easy product to hang making an unbelievable difference!”
We used Wallrock Thermal Liner in my daughter’s bedroom which is part of an extension over the garage and with a flat roof. For years the room has been cold and slow to heat up and the north facing wall has suffered with mould due to condensation. We hung the Wallrock Thermal Liner horizontally and got the hang of the adhesive quantity required for the wall very quickly. Not easy to cut around windows for a DIY customer, a very sharp pair of scissors is needed, but the finished result was great. We then hung a wallpaper over one wall and Wallrock Thermal Liner over the others and painted the room which looks great. The difference to the temperature of the room was immediately and surprisingly noticeable, we are delighted with the results.Kind regards.

My old country house has solid stone walls and boy do they feel cold inside. Not being able to have the cavity insulated -'cos there ain't no cavity -for years I've been seeking a solution to this.
Additionally, in one ground-floor room bad mould had formed on the wallpaper, attributed by experts as moist air contacting the cold wall surface. (The fix for one wall would have cost £3,000). I have an electronic temperature sensor (from an earlier life), and using this in February 2009 I'd found that the surface temperature of the walls was over 5 degrees F colder than the room air. This has the effect of “sucking” heat from the house as well as encouraging mould. It also means that if you try to heat a room for use just in the evening, as we do, it's nearly bedtime before the room reaches a comfortable temperature.
I came across Wallrock Thermal Liner accidentally when I called Retford looking for a tough ceiling paper to cover cracks and other imperfections. Wallrock paper was suggested and I asked whether it had any thermal insulating properties. “Not particularly, but we have a new product about to be launched that has.” That's how I “discovered” the Thermal Liner.
After examining a sample and getting, through Retford, the thermal insulating properties from the German manufacturer, I was sure that in principle it was the answer to my problem. Next I had to decide whether I, an ordinary DIYer, could fix it satisfactorily, because at 3.6mm (just under 3/16 of an inch) thick it's a lot different from ordinary wallpaper.
Advice from Retford and some “thinking cap” activity convinced me that I could, so I ordered sufficient for two rooms plus a landing and stairway.
I've now applied Wallrock Thermal Liner to walls in one of the ground floor rooms. I didn't do the ceiling because the loft is very well insulated. Even in summer, it gets pretty chilly in the evenings high up on the Wiltshire downs. Both my wife and I notice that the room definitely has a very much cosier feel to it, most noticeable in early mornings and in the evenings, without the central heating on, whereas before discovering Thermal Liner it had a distinctly chilly feel. My temperature measuring device does not show any difference between the temperature of the room air and the Thermal Liner surface. I think there must be a difference, but it's too small to register. I emulsioned rather than papered over the Thermal Liner, to save on money, without problems.
Thermal Lining my other areas will be done after other work (CH radiators) is completed.
The Thermal Liner System Adhesive has a very long “open” time – important for me because I'm a slow worker, particularly around the complicated shapes. The first room Thermal Lined has three arched recesses, two rectangular and one semi-circular. I tidied external corners using strips of Retford's Wallrock Ceiling paper, finished off with ready-mixed plaster skim. For gaps in internal corners, caused by wall irregularities in this old house, I filled with caulk.
Thermal Liner is a very tough material that doesn't tear. I found the best way to cut it was good quality scissors. Where I had to make holes in the Thermal Liner to align with existing screw plugs (for curtains etc) I found it easiest to stick a nail in the plug, push the Thermal Liner over the nail, then remove the nail, so leaving a witness mark.
I applied the System Adhesive to walls using a medium pile roller, using a brush around skirting and ceiling where the roller wouldn't “reach”, making sure there was plenty of adhesive on the wall where I used the brush – i.e. I didn't brush it out.
