The best Insulating wallpapers, compared.
Top pick: wishFIRE foam wallpaper Best value: Erfurt Heatsaver – Best value at about £1.30 per square metre if the two-pack is two manufacturer rolls of about 5 m², with 4.3 from 179 reviews and a 200 m² cell you should ignore. Updated October 2026.
Insulating wallpaper in the UK is a thin internal wallcovering, usually expanded polystyrene or a foil-backed sheet, hung to take the chill off a cold wall and to reduce surface condensation. It is a decorating product, not cavity insulation and not insulated plasterboard. Job, coverage and adhesive are set out in the [insulating wallpaper buying guide](/hub/painting-supplies/insulating-wallpaper/sub/insulating-wallpaper-buying-guide). It is expanded polystyrene, a graphite-faced polystyrene liner, a foil sheet sold against the look of penetrating damp, or a peel-and-stick foam. The for Energy treats a flexible lining as a lighter option than boards or a stud wall, usually no more than about 10 mm, and weaker as insulation.

Personal buying guide
Question 1 of 2
What is the wall doing?
wishFIRE's peel-and-stick foam is 2.55 mm of vinyl, 0.44 m by 3 m, which is 1.32 m², listed at £18.99. That works out at about £14.39 per square metre, the highest unit price you can calculate in this set. The star line is 4.4 from 3 ratings, and only two written reviews are on the listing, so the average is not a large UK sample. One buyer says the foam hides small defects and that a pin prick in a bubble disappears into the texture. The other says the backing film is thin and breaks into bits, so peeling it off is slow. The listing says it performs best on a clean, dry, smooth surface and tells you to avoid textured walls and damp areas. There is no R-value and no fire class. It is a removable facing for a small smooth patch, not a measured thermal liner for a cold external wall.
Pros
Cons
Best for: A small, smooth, dry wall in a rental where you want a removable layer and will test a piece first.
Less suitable: A cold external wall you hoped to insulate, a damp stain, or any textured plaster.
Specifications
Common questions
Will it stick to a textured wall?
The listing says it performs best on clean, dry, smooth surfaces and tells you to avoid textured walls or damp areas. Test a small piece first.
Is it a measured insulation liner?
The listing gives 2.55 mm of vinyl foam and 1.32 square metres. It does not state an R-value or a fire class.
What do the two written reviews say?
One buyer says the foam hides small defects and that a pin prick in a bubble disappears into the texture. The other says the backing film is thin and breaks into bits, so peeling it off is slow. The star line is 4.4 from 3 ratings.
Wallrock Dampstop Thermic is one roll at £11.10, with a stated coverage of 5 m² and 4.3 from 584 amazon.co.uk reviews. You paste the wall, and the adhesive is not in the box, so the £11.10 is not the whole cost. Across the 50 texts saved for this listing, buyers who prepared a damp wall and used enough adhesive often say the stain stayed away. The repeated trouble is weak grab, paste drying before a full length is up, and ceilings that are hard to do alone. A review on 29 September 2026 says the roll is 500 mm wide, not the 675 mm that buyer expected, and the specification block does not print a width or a thickness. Erfurt describes the sheet as a barrier against the look of penetrating damp, 500 mm by 10 m, not as 4 mm of foam. Ordinary wallpaper paste often fails in those reviews, so you should budget for the system adhesive and stop if the wall is wet from a leak.
Pros
Cons
Best for: A local penetrating-damp stain on a wall you can paste, if you buy the matching adhesive and the moisture is not structural.
Less suitable: A renter who cannot paste, a ceiling, or a cold-wall job that needs a stated thickness and an R-value.
Specifications
Common questions
Is adhesive in the box?
No. The application field says adhesive and the bullets say paste the wall. The included-components line is a single roll. Reviews say ordinary wallpaper paste often fails and that the sheet needs a stronger glue.
How wide is the roll?
The specification block does not give width. A UK review on 29 September 2026 says it is 500 mm wide, not the 675 mm that buyer expected from the description. Coverage is stated as 5 square metres. Erfurt's page says 500 mm by 10 m.
What do the UK reviews repeat about hanging it?
Across the 50 texts, buyers who prepped a damp wall and used enough adhesive often say the stain stayed away. Repeated trouble is weak grab, paste drying before a full drop is up, and ceilings being hard to do alone.
The Erfurt Heatsaver two-pack is a 2 mm polystyrene underliner listed at £12.99, with 4.3 from 179 amazon.co.uk reviews. Across the 37 review texts saved for this listing, buyers often say a cold wall feels warmer to the touch once the liner is up. The coverage cell says 200 m², while the title says 2 mm by 10 m and the pack is two rolls, so you should not plan a room on that cell. Erfurt's own roll is 10 m by 50 cm, about 5 m², which would make this pack about 10 m² if both rolls match that sheet, or about £1.30 per square metre. The 2 mm sheet tears when you trim it or handle it heavily, and that complaint comes up often. The listing says it is suitable for paint or decorative wallpaper, though Erfurt's page says to hang a lining paper before paint, and the manufacturer figures are an R-value of 0.05 m²K/W and Euroclass E. Nobody in those texts gives a measured change in the heating bill.
Pros
Cons
Best for: One cold, dry wall where you want the lowest price per square metre and will check that each roll is about 5 m² before you order more.
Less suitable: A damp stain, a ceiling, or any job that needs a coverage figure on the listing that matches the title.
Specifications
Common questions
What area does this listing say the pack covers?
The coverage field says 200 square metres. The title says 2 mm by 10 m and the pack is two rolls. The dimension line says 10L x 2W metres. Those figures are not reconciled on the listing, so do not plan a room on the 200 m² cell. Erfurt's roll is 10 m by 50 cm, about 5 m².
Can it be painted?
The recommended-uses line says it is suitable for painting and for decorative wallpaper. Erfurt says to hang a lining paper before paint. The reviews do not name a paint system. Several buyers say the sheet tears while hanging and snags when wallpaper goes over it.
What do the UK reviews repeat?
Of the 37 texts saved for this listing, buyers often say a cold wall feels warmer to the touch. The repeated complaint is that the 2 mm sheet rips when it is trimmed or handled heavily. Nobody in those texts gives a measured change in the heating bill.
Erfurt Graphite Plus is one 4 mm roll at £17.85, sized 7.5 m by 0.5 m, which is the stated 3.75 m². Those three figures agree, which is the point of contrast with the Heatsaver coverage cell in this comparison. Erfurt prints an R-value of 0.125 m²K/W and Euroclass E, and says the graphite sheet is about 20% better than its own standard 4 mm lining paper. That 20% line is the maker's comparison, not a test of your heating bill. The listing says the sheet disguises uneven walls and that it is fire rated, without a class in the specification block. The amazon.co.uk listing has no customer-review line and no review texts, so you cannot see whether it tears the way buyers say the 2 mm Heatsaver does. At about £4.76 per square metre it is the dearest specified liner here, and one roll will not cover a typical wall. The hang method is not on the listing.
Pros
Cons
Best for: A cold, dry wall where you want the thicker Erfurt sheet and will buy without UK reviews on this listing.
Less suitable: Anyone who wants a large review sample, a damp-stain barrier, or a peel-and-stick layer for a rental.
Specifications
Common questions
How much wall does one roll cover?
The listing says 7.5 m by 0.5 m and 3.75 square metres. That is one roll, not a twin pack.
Does the listing give an R-value or a fire class?
The listing says the sheet is fire rated and CFC-free, and that laminated polystyrene increases heat saving. It does not print an R-value, a Euroclass, or a decibel figure. Erfurt's page states 0.125 m²K/W and Euroclass E.
What do buyers say?
The amazon.co.uk listing has no customer-review line and no review texts, so there is no UK review sample for this ASIN.
This generic 9 mm peel-and-stick roll is listed at £21.99, with China as the origin and foam, XPE, an aluminium film, and PVC in the material line. Nine millimetres is the thickest foam stated in this comparison, but the listing has no length and no square-metre coverage, so you cannot tell how much wall one roll covers. There is no customer-review line to set against the reusable-adhesive bullet. A bullet says the PVC is heat-resistant and flame-resistant, and another says the foil adhesive is reusable, with no Euroclass and no reviews to check either claim. The listing does not state an R-value. The rank on the listing is 222,774 in DIY & Tools, which is a sales position, not a fire test or a warmth test. Until the live page prints a roll size, you are buying a thickness claim and a white colour, not a planned area.
Pros
Cons
Best for: Only if you open the live amazon.co.uk page and a roll length is printed before you pay.
Less suitable: Anyone planning a wall from this listing, or a cold wall that needs a stated R-value and a known area.
Specifications
Common questions
How much does one roll cover?
The listing does not answer that. There is no length or square-metre figure in the specification block.
Does the listing prove it is flame-resistant?
A bullet says the PVC is heat-resistant and flame-resistant. No Euroclass or British class is printed. Treat that as a seller claim, not a tested class.
Can it be removed cleanly?
A bullet says the aluminium-foil adhesive is reusable. There are no reviews on the listing to check that claim.
Five amazon.co.uk listings, with prices saved on 20 October 2026, were scored from 0 to 100. Declared build is 50, UK buyer evidence is 25, hang and finish path is 15, and the fire line is 10. Price per square metre is not inside the score. It decides the best-value badge on its own. A star average is not an R-value test. No customer-review line scores as a gap, not as one star. A coverage cell that contradicts the title is cut hard. This is not a laboratory test. The top pick is the highest score, once. Best value is the lowest shelf price per square metre once coverage is taken from a figure you can reconcile, once.
Declared build
50%Thickness, a coverage figure that matches length times width, and a manufacturer R-value where Erfurt prints one. A coverage cell that contradicts the title is cut hard. A peel-and-stick foam with a matching area and no R-value does not score like a specified liner.
UK buyer evidence
25%Stars count with the review sample on that listing. No customer-review line scores as a gap, not as a one-star result. Fewer than 10 ratings are capped, then lose points for a written fault such as a sheet that tears or paste that fails to grab.
Hang and finish
15%A named paste-the-wall method scores higher than an empty method field. A self-adhesive listing that tells you to avoid damp and texture scores for that warning. A paint line that the reviews and the maker then qualify scores in the middle.
Fire line
10%Fire rated with no class, plus Euroclass E on the manufacturer page, scores in the middle of this block. A specification with no fire line scores lower. A bullet that says flame-resistant, with no class, is not treated as a tested lining class.
Buy the roll for the job and for a coverage figure you can reconcile, not for a warmth claim in the title. Five amazon.co.uk listings were scored from the saved pages of 20 October 2026. A cold dry wall, a local damp stain, and a rental where you cannot paste are three different products. A star line with no reviews is not an R-value. The top pick and the best value are named from those scores. Neither result is a laboratory test.
Insulating wallpaper is a thin wallcovering you hang on the room side of a wall. In this set it is expanded polystyrene, a graphite-faced polystyrene liner, a foil sheet sold against the look of penetrating damp, or a peel-and-stick foam. It is not cavity insulation, and it is not insulated plasterboard. The Centre for Sustainable Energy treats a flexible lining as a lighter option than boards or a stud wall, usually no more than about 10 mm, and weaker as insulation.
The Heatsaver twin pack prints 200 m². The title is 2 mm by 10 m, two rolls, and Erfurt's roll is 10 m by 50 cm, about 5 m². Plan the room on about 10 m² for the pack if both rolls match that sheet.
Erfurt says to line Heatsaver before paint. Dampstop's foil face does not take ordinary wallpaper paste, and the adhesive is not in the box. Budget for the system adhesive.
Do not hang these sheets over a leak, rising damp, or widespread mould. Euroclass E is not, on its own, a lining for a new escape route. Peel-and-stick listings in this set tell you to avoid damp areas.
Declared build is 50 of the 100 points. Start with a thickness, a coverage figure that matches length times width, and a manufacturer R-value where Erfurt prints one. Graphite Plus is 4 mm, 7.5 m by 0.5 m, and 3.75 m², and those three figures agree. Erfurt states 0.125 m²K/W and says the graphite sheet is about 20% better than its own standard 4 mm lining paper. That 20% line is not your heating bill. Heatsaver is 2 mm at 0.05 m²K/W. The listing coverage cell says 200 m².
Hang and finish is 15 points, and the fire line is 10. A named paste-the-wall method scores higher than an empty method field. Wallrock says paste the wall and states that adhesive is not included. Ordinary wallpaper paste often fails in the saved reviews, so the £11.10 is not the whole cost. wishFIRE says it performs best on a clean, dry, smooth surface and tells you to avoid textured walls and damp areas. Graphite Plus and Heatsaver leave the hang method off the listing.
Three typical situations, each with a recommendation from this comparison.
You want a decorating job on a dry wall, not a stud wall. Erfurt Graphite Plus at about £17.85 is 4 mm, 3.75 m², with a manufacturer R-value of 0.125 m²K/W and Euroclass E. The listing has no review line, and one roll will not cover a typical wall.
You need a layer you can peel off, and you must not hide mould. wishFIRE at about £18.99 is 2.55 mm of self-adhesive vinyl, 1.32 m², with 4.4 from 3 ratings. The listing says to avoid textured walls and damp areas. There is no R-value.
You can paste the wall, and the moisture is not structural. Wallrock Dampstop Thermic at about £11.10 states 5 m² and 4.3 from 584 reviews. Adhesive is not in the box, ordinary paste often fails to grab, and there is no thickness and no R-value. Stop if the wall is wet from a leak.
The top pick is Erfurt Graphite Plus at about £17.85. It is the highest score: 4 mm, 7.5 m by 0.5 m and 3.75 m² agree, and Erfurt states an R-value of 0.125 m²K/W and Euroclass E. The listing has no review line, one roll is only 3.75 m², and the hang method is not printed. The best value is the Erfurt Heatsaver two-pack at about £12.99: 2 mm, 4.3 from 179 reviews, and about £1.30 per square metre if both rolls match the manufacturer sheet of about 5 m². The coverage cell that says 200 m² conflicts with the title, and buyers say the sheet tears when trimmed. Neither result is a laboratory test or a measured cut in a heating bill.
Erfurt Heatsaver
Best value at about £1.30 per square metre if the two-pack is two manufacturer rolls of about 5 m², with 4.3 from 179 reviews and a 200 m² cell you should ignore.
