The best roller shutter insulation packs, compared.
Top pick: Schellenberg 66267 – Highest star line in the set: two 3 mm rolls, 4.2 from 343 reviews, at about £17.28. Best value: Schellenberg 66272 – Lowest shelf price, about £4.45, for two Neopor cheeks. Not a full box lining. Updated October 2026.
Roller shutter insulation is a lining for the box that holds a rolled shutter curtain, so the thin room-side board is less of a cold bridge and less of a draught path. You need a built-in box with a lid you can open above a window or a patio door. A face-fixed external box is a weaker case, because the cold air is already outside the heated room. What matters is the thickness you still have room for when the curtain is fully raised, a fixing you can control, and a pack that covers the face you measured. Garage seals, window film and a complete shutter are not in this set. Thickness, faces and fixing are set out in the [roller shutter insulation buying guide](/hub/heating/roller-shutter-insulation/sub/roller-shutter-insulation-buying-guide).

Personal buying guide
Question 1 of 2
Which face is bare?
The Schellenberg 66267 lines an uninsulated roller shutter box with two self-adhesive rolls, each 150 cm by 37.5 cm and 3 mm thick. Across 343 amazon.co.uk reviews, rated 4.2, people who describe the thin roll say the adhesive holds and the draught at the box stops, and several people who do not call themselves professionals report a short install. The sheet cuts easily and is thin enough for a small gap, and comments mention older shutter boxes. The adhesive grabs at once and will not reposition; one review says it stuck to the curtain and entered a guide, with damage. A 3 mm layer is the recurring limit, and one thermal-camera comment saw little difference between a lined box and an unlined neighbour. The title also prints model 66258, and the first 50 saved texts mix this sticky roll with a thicker rigid kit, so a broken-polystyrene note may belong to the other number. A wide box needs a second pack, so about £17.28 buys the two rolls, not always the finished job.
Pros
Cons
Best for: Older uninsulated roller shutter boxes with a small gap
Less suitable: Wide boxes that need a second pack, modern integrated boxes where the curtain rubs, and buyers who wanted a thick rigid liner
Specifications
Common questions
What thickness does the amazon.co.uk listing print?
3 mm, as two rolls of 150 cm by 37.5 cm. The title also names model 66258, while the model cell is 66267.
Is the pack self-adhesive?
The bullets say self-adhesive insulation for uninsulated roller shutter boxes. Reviews say the adhesive grabs at once and can stick to the curtain.
What review line sits on the listing?
4.2 out of 5 (343 reviews). The saved review texts are mostly not British English, and some describe a rigid kit rather than a 3 mm roll.
The Schellenberg 66257 is one 13 mm plastic mat, 100 cm by 50 cm, for a narrow roller shutter box, including a box close to a door. The amazon.co.uk line is 4.1 from 31 reviews; 11 texts are saved, and one of those is about a mattress, not this mat. Reviewers who fitted it call the job quick in a small box, and one could take the mat out again to clean the shutter. Noise reduction comes up more than once, and one comment still found it satisfactory after some time in use. In that same small sample, boards arrived broken and were held together only by the fleece facing, including a second delivery for the same buyer. The thin sheet tears when it is cut, and grooves force it to be wrapped, which reviewers found awkward inside the box. At least one buyer still could not say whether the room was any warmer, and at about £35.61 this is the highest price of the three.
Pros
Cons
Best for: Narrow roller shutter boxes, including boxes close to doors
Less suitable: A sheet that has to survive cutting without tearing, or a heat result checked against a large review sample
Specifications
Common questions
Is this the narrow-box mat?
The bullets say it is for narrow roller shutter boxes, close to doors for instance, at 1000 by 500 mm and 13 mm thick.
Are the instructions in English?
The listing says the pack includes one insulation mat and assembly instructions, and it prints the word English. The saved line stops after that word.
What review line sits on the listing?
4.1 out of 5 (31 reviews). Saved texts mention broken boards in the carton and a sheet that tears when cut. One review is about a mattress.
The Schellenberg 66272 is two 15 mm Neopor side panels, printed as 36 cm by 30 cm, for the cheeks of a roller shutter box rather than a full lining. Across 214 amazon.co.uk reviews it scores 4.0, and the 45 saved texts are almost all in Spanish, Italian, German or French. People who already had the box open cut the boards with a knife and fixed them with ordinary mounting adhesive; after trimming, the 300 by 360 mm pair matches a typical cheek. Some of those users report less draught, less dust, or a small comfort difference against an untreated box. The photos are the complaint that keeps coming back: they look like a full kit, and reviewers sent the pack back when they found only two side panels. The boards are rigid, they snap if they are flexed, and some arrived cracked. They are too short for a deeper box, and one fitter found them useless beside the axle brackets. At about £4.45 this is the lowest shelf price here, though a few reviewers still call the panels dear next to a builders' merchant sheet of polystyrene.
Pros
Cons
Best for: The two side cheeks of a roller shutter box that is already open
Less suitable: A full box lining, a deeper box, or a cheek blocked by axle brackets
Specifications
Common questions
Does this pack line the whole box?
No. Included components are two roller shutter box insulation side panels. The bullets call them a supplement to the insulation mat.
What size and material does the listing print?
15 mm Neopor. Dimensions are printed as 36 cm by 30 cm, and a bullet also prints 300 by 360 mm.
What review line sits on the listing?
4.0 out of 5 (214 reviews). Saved texts are mostly not British English. A repeated complaint is that the photo looks like a full liner.
Three amazon.co.uk listings are compared. The 1–10 rating on each row follows the star line: the saved 0–100 figure is the star average times twenty (4.2 becomes 84, 4.1 becomes 82, 4.0 becomes 80), then that figure divided by ten plus 0.2. There is no lab test. The weights below are how a pack was judged against the box. They are not a second score. The top pick is the Schellenberg 66267, the highest of those star lines. Best value is the Schellenberg 66272 at about £4.45. It is two side panels, not a full lining.
Thickness and clearance
28%Spare depth is measured with the curtain fully raised, when the roll is fattest. A gap of a few millimetres cannot take the 13 mm mat. The 3 mm rolls are the pack for that limit. A 13 mm board is listed for narrow boxes, including a box close to a door.
Faces and coverage
26%Side panels, two pieces at 300 mm by 360 mm and 15 mm, cover the cheeks only. The rolls and the 13 mm mat cover the long inner face. A photo that looks like a full kit is the usual miss on the cheek pack. A wide opening can need a second pack.
Fixing
18%Self-adhesive grabs at once and will not reposition. Reviews say it can stick to the curtain and enter a guide. Rigid mats are bent in and fixed. Schellenberg's note on the rigid mats says non-expanding foam. The belt slot and any motor cable stay clear.
Listing identity
16%The roll card mixes 66267 and 66258, prints Fabric in the material cell, and the saved reviews describe both a thin sheet and a rigid kit. The UK bullet prints WLG 035. A French page for 66267 prints WLG 033. Manufacturer classes that are missing from the UK card are not treated as the listing.
Stars and shelf price
12%The row rating follows the amazon.co.uk star line, not a lab. The rolls are 4.2 from 343 reviews, the panels 4.0 from 214, and the mat 4.1 from 31. Saved shelf prices are about £17.28, about £4.45 and about £35.61. The lowest price is best value only as two cheeks.
Roller shutter insulation lines a built-in box you can open. The choice is the face you measured, then the thickness that still clears the raised curtain, then a fixing that stays off the curtain. Prices and stars are the saved amazon.co.uk cards for three Schellenberg packs. This is not a lab test, and a WLG group is not a thickness.
Roller shutter insulation is a lining for the box that holds a rolled shutter curtain. The thin board on the room side is a cold bridge and a draught path. You need a built-in box with a lid you can open above a window or a patio door. A face-fixed external box is a weaker case, because the cold air is already outside the heated room. Garage door seals, brush strips, window film, PVC blinds and a complete roof-window shutter are a different search. They are not this comparison.
WLG 035 on the UK roll bullet is a conductivity group, not a millimetre figure. A French page for the same model prints WLG 033. The side-panel manufacturer page says WLG 031, and that class is not on the UK listing. Read the thickness, then the label in the parcel.
The Schellenberg 66272 is two side panels. Reviewers say the photos look like a full kit. If the cold face is the long inner board, the rolls or the 13 mm mat are the packs that cover it. The Consumer Rights Act 2015 requires the goods to match the description.
The self-adhesive rolls grab at once and will not reposition. One review says the sheet stuck to the curtain and entered a guide. Schellenberg's note on the rigid mats says non-expanding foam. Leave the belt slot and any motor cable free.
Start with the box, then the gap, then the bare face. Built-in, with a lid you can remove, is the job. External boxes and garage roller doors are different products. With the curtain fully raised, a few millimetres of spare depth rules out the 13 mm mat. The Schellenberg 66267 is two rolls, each 150 cm by 37.5 cm and 3 mm, at about £17.28. The Schellenberg 66257 is one mat, 100 cm by 50 cm and 13 mm, at about £35.61, listed for narrow boxes including a box close to a door.
Self-adhesive is the fixing on the 3 mm rolls. It holds, and it will not peel back for a second try. Reviews include a curtain and a guide that took the adhesive. The 13 mm mat and the side panels do not print a fixing on the UK card. The manufacturer note for the rigid mats says non-expanding foam. Ordinary mounting adhesive is what reviewers used on the cheeks. Isolate a 230 V tubular motor before you work beside it, and do not cover the belt slot or a motor cable.
Three typical situations, each with a recommendation from this comparison.
You can open the lid and the spare depth is only a few millimetres with the curtain raised. The top pick is the Schellenberg 66267 at about £17.28: two self-adhesive 3 mm rolls, 150 cm by 37.5 cm, with 4.2 from 343 reviews. A 13 mm board can rub in that gap. A wide box can need a second pack.
The box is already open and the bare faces are the two cheeks, not the long inner board. Best value is the Schellenberg 66272 at about £4.45: two 15 mm Neopor side panels, with 4.0 from 214 reviews. The photos look like a full kit. The pack is not one. A deeper cheek, or axle brackets, can still block the fit.
You have room for a board and the listing you want is the narrow-box mat, including a box close to a door. The Schellenberg 66257 is one 13 mm mat, 100 cm by 50 cm, at about £35.61, with 4.1 from 31 reviews. The sample is small, and saved texts mention boards that arrived broken and a sheet that tears when cut.
The top pick is the Schellenberg 66267 at about £17.28. It is two self-adhesive 3 mm rolls, 150 cm by 37.5 cm, with 4.2 from 343 reviews. Best value is the Schellenberg 66272 at about £4.45, two 15 mm Neopor side panels, with 4.0 from 214 reviews. The panels cover the cheeks only. Skip the rolls if the curtain already rubs or you wanted a rigid board. Skip the panels if the cold face is the long inner board. The 13 mm mat, Schellenberg 66257 at about £35.61, is the narrow-box board, with 4.1 from 31 reviews.
Schellenberg 66267
Highest star line in the set: two 3 mm rolls, 4.2 from 343 reviews, at about £17.28.
Schellenberg 66272
Lowest shelf price, about £4.45, for two Neopor cheeks. Not a full box lining.
