The best flue tapes, compared.
Top pick: BOMEI PACK aluminium foil tape 300 mm Best value: BOMEI PACK aluminium foil tape, 3 × 50 mm × 50 m – Best square-metre price among the other rolls with at least 50 reviews and one agreed length: three rolls of 50 mm × 50 m at about £19.99. Updated 22.10.2026.
Flue tape in UK heating catalogues is self-adhesive aluminium foil on a liner. You buy it to close a duct seam, to cover a joint in foil-faced insulation, or to wrap the jacket around a liner. It is not the seal on a gas flue, a plastic condensing flue, or a stove pipe. Those joints are rope, fire cement, or the manufacturer's clip, and gas work belongs to a Gas Safe registered engineer. A suitable roll is the one whose width, length and printed temperature agree on the same page. About 50 mm is the width merchants name for a liner jacket. Wider tape covers a board seam. A short roll suits a patch, and a roll near 50 m suits a loft. Foil thickness only counts when the listing prints one figure. A stated degree is the number on that page, not a chimney class under BS EN 1443 or BS EN 1856. How to read width, length and a printed temperature is set out in the [flue tape buying guide](/hub/diy-supplies/flue-tape/sub/flue-tape-buying-guide).

Question 1 of 2
What are you covering?
This BOMEI PACK row is the 300 mm foil tape at about £35.99, with a star line of 5.0 from five reviews and no UK review text saved for this listing. The title says 55 yards, which is about 50.3 m, while the size field says 1,650.92 m and the unit count says 1.0 metre. Those three lengths cannot be averaged into a price per metre. The page states 180 °C and waterproof, and it names heating and ventilation ducts, with no micron. A perfect star line on five reviews, and no saved review text, is not evidence that the roll arrived at any one of those lengths. The width is the only dimension that is not in open conflict. Leave it in the basket until a listing shows one length you can check against the carton.
Pros
Cons
Best for: You are only comparing the 300 mm width and you will not buy until the length fields agree.
Less suitable: Any order that needs a known length, a price per metre, or a review file you can read.
Specifications
Common questions
How long is the 300 mm roll?
Do not quote a length. The title says 55 yards, the size name says 1,650.92 m, and the unit count says 1.0 metre. Width is 300 mm.
Were UK review texts saved?
No. The listing line is 5.0 from 5 reviews. No review text was saved, so praise and faults from UK buyers are not on file for this roll.
This BOMEI PACK pack is three rolls of 50 mm by 50 m at about £19.99, so the agreed length is about 150 m of 50 mm tape. The listing states −20 °C to 180 °C and waterproof, with no standard named and no micron. It scores 4.8 from 276 amazon.co.uk reviews. Forty-three UK reviews read for this listing mostly describe PIR, vapour barrier and loft joints. Hand tear is stated, and several people could start the liner, though long strips curl and stick to themselves. The foil feels thin, and once it is pressed it is hard to lift. The material field mentions copper, which the bullets do not explain. About £2.67 per square metre is the value case against the short Gladiator roll, provided you do not need a 110–120 °C datasheet. It is best value for a long board run. Skip it for a gas flue, and skip it if a missing micron is a problem.
Pros
Cons
Best for: You are covering a long run of PIR or vapour-barrier joints and you can work in short strips.
Less suitable: A job that needs a 110–120 °C datasheet, a stated foil thickness, or a gas-appliance approval.
Specifications
Common questions
What temperature range does this three-pack state?
The bullets state −20 °C to 180 °C. They also state moisture, weather, waterproof, UV and chemical resistance. No standard is named.
How much tape is in the pack?
Three rolls, each 50 mm by 50 m. The item count and the title agree on three rolls.
Does the listing approve it for a gas appliance?
No. The title names HVAC ducts, pipes and insulation. The listing does not add a gas-appliance approval.
Ealyder lists a heavy-duty aluminium foil tape at 75 mm by 59.4 m for about £14.99, with waterproof on the page and no degree figure at all. The amazon.co.uk line is 4.8 from 74 reviews. Nine UK reviews read for this listing describe camper insulation, a hot air-conditioner outlet where other tapes peeled, and one motorbike exhaust wrap with no discolouration reported by that buyer. There is no UK complaint cluster in those nine reviews. Foil thickness is not printed, so heavy duty is a title phrase rather than a micron. Hand tear is stated on the listing. The length is the longest agreed roll here, which suits a van or a long board run if you do not need a temperature on the page. Skip it when a printed limit, or a datasheet such as 110–120 °C, is the reason you are buying.
Pros
Cons
Best for: You want a long 75 mm roll for camper or board insulation and you do not need a printed temperature.
Less suitable: Any job where the listing must state a degree figure before you buy.
Specifications
Common questions
Does Ealyder print a temperature?
No. The bullets say high and low temperature and name furnace and boiler sealing, HVAC and exhaust. They do not print a degree figure or a standard.
Do the width and length agree?
Yes. The listing agrees on 75 mm by 59.4 m, one roll. It also states waterproof.
Bergmis lists 50 mm by 50 m at about £9.99, with 4.8 from 15 amazon.co.uk reviews and 13 UK reviews read for this listing. Those notes say it is sticky, easy to cut, and long enough for van and loft jobs, and that it moulds because it is thin. The same buyers say it tears while you position it, the liner is fiddly, and the start of the roll arrived covered with clear tape. One UK reviewer measured 0.05 mm and argued with a heavier-duty reading of the title. The listing itself does not settle that argument: bullets say −30 °C to 120 °C, other fields say 180 °C and 10 °C, and thickness appears as both 23 micron and 50 micron. Fifteen reviews is also under the badge line. You can use the agreed 50 m length only if you refuse to quote one temperature or one thickness from this page.
Pros
Cons
Best for: You already accept a conflicted listing and only need the agreed 50 mm × 50 m length.
Less suitable: Anyone who needs one temperature, one micron, or a review file of 50 or more.
Specifications
Common questions
Which temperature should you quote for Bergmis?
None as a single figure. The bullets say −30 °C to 120 °C. Other fields say 180 °C and 10 °C. Length is the part that agrees: 50 mm by 50 m.
Which thickness is printed?
Both. Foil thickness is 23 micron and item thickness is 50 micron. One UK review measured 0.05 mm. Do not collapse those into one gauge.
BOMEI PACK titles this as three rolls of 25 mm by 50 m at about £15.99, with a bullet range of −20 °C to 180 °C and waterproof. The star line is 4.8 from five reviews, and one UK review was saved. That buyer praised strength, tack and a proper backing, and said the foil was thicker than other tapes that had felt too thin. The same review complained that the pack was sold as three rolls when one roll was wanted. The page does not settle the count: the title says three, the number of packs says one, and the number of items says three. The unit count says 1.0 metre against a 50 m title. No micron is printed. A 25 mm width is a narrow wrap, not a board joint. Order it only after you have decided whether one roll or three is what the carton will contain.
Pros
Cons
Best for: You have already checked that a narrow 25 mm wrap, in the pack count you expect, matches the job.
Less suitable: A PIR board joint, or an order placed on the title’s three rolls without reading the pack fields.
Specifications
Common questions
How many rolls are in the 25 mm pack?
The title says three rolls of 25 mm by 50 m. Number of items says 3 and number of packs says 1. The unit count says 1.0 metre.
What heat range is stated?
The bullets state −20 °C to 180 °C. The narrow width is the point of this roll: pipes and duct seams, not a wide board joint.
The 100 mm BOMEI PACK roll is 50 m at about £17.99, and the width and length fields agree. The listing states 180 °C and waterproof, with no micron and no standard. The star line is 4.7 from 114 reviews, with 20 UK reviews read for this listing. Those notes praise tack on shed insulation, Celotex-type boards and a door foam slab, and several buyers found the liner easy to release. The bond is strong enough that repositioning is the complaint, and one buyer called it expensive next to a cheaper marketplace roll. There is no cluster of peeling in those 20 UK reviews. One note mentions a gas-fire flue joint that a later service did not flag; that is a review, not permission to tape a gas flue. Use the width on a broad board seam. Leave it if you need to lift and reset the tape, or if the surface is the flue itself.
Pros
Cons
Best for: You want a 100 mm band on foil-faced board joints and you will place it once.
Less suitable: A temporary hold, a stated micron, or any gas flue joint.
Specifications
Common questions
What size is this BOMEI PACK roll?
One roll, 100 mm by 50 m. Width and length agree on the listing.
What heat range is printed?
The bullets state −20 °C to 180 °C, plus a waterproof claim. No foil-micron figure is printed.
This BOMEI PACK roll is 75 mm by 50 m at about £15.99, and the width and length agree. The listing states −20 °C to 180 °C, waterproof and hand tear, with no micron. It is 4.7 from 75 amazon.co.uk reviews. Fourteen UK reviews read for this listing describe very strong tack on a vent pipe and on foil insulation. The 75 mm width is the point those buyers liked on insulation joints. One buyer sealed a motorbike tank opening against cleaning fluid for 24 hours, which is a short chemical hold, not a flue test. The repeated limit is that the tape will not come off if you meant the job to be temporary. There is no repeated product failure in those 14 UK reviews. It is a sensible mid-width loft roll when 50 m and 75 mm match the seam. It is a poor choice for masking you expect to lift the same day.
Pros
Cons
Best for: You are sealing insulation joints or a vent pipe with a 75 mm band you will leave in place.
Less suitable: A temporary cover, or a specification that demands a micron and a named test standard.
Specifications
Common questions
What size is the 75 mm BOMEI PACK roll?
One roll, 75 mm by 50 m. Width and length agree. The bullets state −20 °C to 180 °C and waterproof.
Is hand tear stated?
Yes. The bullets say the tape can be torn by hand and claim no adhesive is left when it is peeled.
The wide BOMEI PACK roll is 150 mm by 50 m at about £19.99, and the width and length fields agree. The listing states 180 °C and waterproof, with no micron. The star line is 4.6 from 39 reviews, which sits under the 50-review line used for the badges, and eight UK reviews were read. Those notes describe gaps between 50 mm insulation boards and joists, and vapour barrier kept continuous between Celotex strips. One buyer called the foil thin, and another said it was only just OK. There is no pile of failures in that small file. The width covers a broad seam that 50 mm tape would only bridge in the middle. Treat 39 reviews as a thin sample. Skip it if you need a larger review file or a stated foil thickness.
Pros
Cons
Best for: You need a 150 mm band across wide board gaps and you accept a review count under 50.
Less suitable: A shortlist that requires 50 or more reviews, or a job that needs a printed micron.
Specifications
Common questions
How wide is this roll?
150 mm by 50 m, one roll. Width and length agree. The bullets state −20 °C to 180 °C and waterproof.
Is a foil thickness printed?
No. The listing does not print a foil thickness.
The Gladiator roll is 50 mm by 10 m of 30 micron foil at about £5.95, and the listing states 120 °C. Across 1,568 amazon.co.uk reviews the line is 4.5. Fifty UK reviews read for this listing often describe strong tack on ducting, insulation boards, an air-conditioner hose and pipe lagging. The same thin foil that cuts and moulds easily is the repeated complaint, and the liner has no easy tab. One buyer watched it leave a hot exhaust box after three or four days, and another put the cost near 60p per metre against longer packs. Width, length and the 30 micron figure agree, and the page states water resistance. It is the top pick for a short duct or board patch where 10 m is enough and you are taking 120 °C from the listing. Leave it when the job needs about 50 m, or when the surface is a gas flue or a stove pipe.
Pros
Cons
Best for: You want a short 50 mm patch on a duct or foil-faced board, and 10 m plus a stated 120 °C is enough.
Less suitable: A loft that needs about 50 m, a hot exhaust box, or any gas flue or stove joint.
Specifications
Common questions
What heat limit does the Gladiator listing state?
The listing states 120 °C. It also states that the tape is water resistant and that the foil is 30 micron.
How long is the roll?
One roll, 50 mm by 10 m. The title, the size and the unit count agree.
What jobs does the listing name?
The title and bullets name ducts, insulation, HVAC, extractors and vents. The page does not add a gas-appliance approval.
ArmaKit is the lowest shelf price in the set at about £3.45 for 48 mm by 10 m, and it states 50 micron foil. The listing is water resistant and aimed at loft insulation and radiators, but it prints no degree figure despite a heat-resistant bullet. The star line is 4.5 from 115 reviews, with 29 UK reviews read for this listing. Those notes cover loft boards, radiator foil and pipe lagging, and some buyers found it sticky and easy to tear. Others called it thin or paper-like, struggled to start the liner, and one said it did not stick and bought something else. One UK review measured closer to 9.5 m or 9.6 m than the stated 10 m. At this price it is a small-job roll, not best value once you need about 50 m. Buy it for a short radiator or lagging patch if a missing temperature is acceptable.
Pros
Cons
Best for: You have a small loft-board, radiator-foil or lagging patch and about £3.45 for 10 m is the budget.
Less suitable: A 50 m run, or any purchase that needs a printed temperature before you order.
Specifications
Common questions
How thick is the ArmaKit foil?
The listing states 50 micron. The size on the title is 48 mm by 10 m, one roll.
What temperature does ArmaKit print?
None. A bullet says heat resistant and does not give degrees. The page asks about flame retardant and does not answer with a standard.
The 3M 2113NA listing is a short high-temperature flue tape at about £11.94, about 38 mm by 4.6 m, and it states heat resistance up to 600 °F. The amazon.co.uk line is 4.4 from 4,104 reviews. That count is the listing total, not a UK sample: only 17 of the first 50 reviews read were UK. Some of those UK notes describe a cleaned kerosene flue hole or a rain leak when the tape sat over screws, not as the only joint. Others say it would not stay on a steel stove pipe, that the roll is thin, and that the adhesive failed within minutes for one buyer. The 1.5 inch thickness field is the width filed in the wrong place. At about £2.61 per metre it is a small patch, not a 50 m HVAC roll. Buy it only when a short hot-air duct patch matches the title, and skip it for a wood-burner pipe or a loft.
Pros
Cons
Best for: You need a short patch on a hot-air duct and you accept one 4.6 m roll at about £11.94.
Less suitable: A loft, a wood-burning stove pipe, or anyone treating the review count as UK evidence.
Specifications
Common questions
What temperature does the 3M listing state?
The listing states heat resistance up to 600 °F. A Celsius conversion of that figure is arithmetic, not a second test printed on the page.
How much tape is on the roll?
The title lines agree on about 1.5 in by 15 ft, also given as 5 yd, which is about 38 mm by 4.6 m. It is one short roll, not a 50 m HVAC roll.
What does the listing say the tape is for?
The bullets name leaks from hot air ducts. The item type is flue tape. The page does not add a separate warning block.
The black BOMEI PACK roll is titled 100 mm by 50 m at about £16.99, and the title and size name agree on that length. The unit-count field says 1.0 metre, which is the conflict to notice before you compare it with the silver 100 mm roll. The listing states 180 °C and waterproof, with no micron. The star line is 4.1 from four reviews, the weakest rating in the set, and one UK review was saved. That review reported on-time delivery and no fault on an unnamed job. Black is a colour, not a higher heat rating. Four reviews cannot tell you how the foil behaves on PIR or on a duct. If you specifically want a black 100 mm band and you accept that sample, the width matches a board joint. Otherwise the silver 100 mm listing, with 114 reviews, is the one with a readable UK file.
Pros
Cons
Best for: You want a black 100 mm roll and you accept four reviews and a unit-count conflict.
Less suitable: A larger review file, a heat decision based on colour, or a loft where you need more than four reviews.
Specifications
Common questions
What colour is this roll?
Black. The title and size name agree on 100 mm by 50 m. The unit-count field says 1.0 metre, so that field is not the length.
How many UK reviews were read?
One review, inside a listing line of 4.1 from 4 reviews. That review states no fault. It is not a sample you can rank from.
Shelf prices, stars and review notes are the amazon.co.uk snapshot of 21 October 2026 already stored for these twelve listings. This is not a laboratory test. The card score is the star line scaled to 70, plus a review-volume term capped at 30. That 0–100 figure is shown on the page divided by 10. A badge needs at least 50 reviews and one agreed length. The highest score is the top pick. Best value is the best square-metre price among the other rolls that pass that bar. A printed degree is the figure on that listing, not a BS EN 1443 or BS EN 1856 class. A gas flue and a stove joint are not scored as tape jobs.
Amazon star line
70%Stars on the amazon.co.uk line, scaled so a 5.0 would contribute 70. The stored stars are divided by 5, multiplied by 70, and then combined with the volume term before rounding.
Review volume
30%Up to 30 points from the size of the review count: ten times the log10 of the count, floored, and capped at 30. A 5.0 from five reviews cannot lead on volume alone. The count on a short roll is still that listing’s count, not a UK sample.
You are matching aluminium foil tape to a duct seam, a foil-faced board, or the jacket around a liner. A gas flue and a stove joint are a different material and a different person. The twelve amazon.co.uk listings captured on 21 October 2026 run from about £3.45 to about £35.99. The top pick is a short 50 mm roll that states 120 °C. Best value is a long 50 mm pack for board joints, and only when you do not need a 110–120 °C datasheet. None of these listings shows a chimney class.
Flue tape in a UK heating catalogue is self-adhesive aluminium foil with a release liner. You use it on a duct seam, on foil-faced insulation, or on the jacket around a liner. A gas flue, a plastic condensing flue and a stove pipe are different jobs. Approved Document J names proprietary jointing, or rope and fire cement, for combustion joints. It does not name foil tape.
Foil tape is for a duct, a board or a liner jacket. A gas flue is Gas Safe work. A stove joint is rope, fire cement, or the clip the appliance maker specifies.
180 °C with no standard, and 600 °F on a short roll, are figures on those pages. They are not BS EN 1443 or BS EN 1856, and converting Fahrenheit is not a second test.
If the title, the size and the unit count disagree, there is no fair price per metre. The same applies when two thickness fields, or two temperatures, sit on one page.
Name the surface before you name a roll. UK reviews on these listings mostly describe insulation boards, duct seams and radiator foil. A gas flue, a plastic condensing flue and a stove pipe are a different job. Approved Document J names rope and fire cement for combustion joints, not foil tape. Then read one temperature. Advance Tapes publishes about 110 °C continuous on AT500, and PAR publishes about 120 °C. A page that states 180 °C with no standard is not that datasheet.
About 50 mm is the liner-jacket width merchants name. 75 mm and 100 mm cover a wider seam. 25 mm is a narrow wrap. A roll near 10 m is a patch, and a roll near 50 m is a loft. Quote a price per metre only after the length is one number. Foil thickness counts when one micron is printed. Two thickness fields are not one gauge. A large review count on a 4.6 m roll is still a short roll, and that count is not automatically a UK sample. Cloth tape on a warm joint is a different product.
Three typical situations, each with a recommendation from this comparison.
You need about 10 m of 50 mm foil and a temperature printed on the page. The Gladiator roll is the top pick at about £5.95. It states 120 °C and 30 micron, with 4.5 from 1,568 reviews. The foil is thin, and it is the wrong roll for a loft or a gas flue.
You are covering PIR, a vapour barrier or a loft run and you can work in short strips. The three-roll pack is best value at about £19.99, three agreed rolls of 50 mm by 50 m, 4.8 from 276 reviews. It states −20 °C to 180 °C with no standard and no micron.
The joint is wider than a 50 mm band and you will place the tape once. The 100 mm roll is about £17.99, 50 m, 4.7 from 114 reviews, and UK notes mention shed insulation and foil-faced boards. It states 180 °C with no micron. It is not a gas-flue joint.
The top pick is the Gladiator aluminium tape at about £5.95. The card score is 93, shown as 9.3: 50 mm by 10 m, 30 micron, a stated 120 °C, and 4.5 from 1,568 reviews. UK reviews describe ducting, boards and lagging, and they also call the foil thin. Skip it for a loft that needs about 50 m, a hot exhaust box, or any gas flue or stove joint. Best value is the BOMEI PACK three-pack at about £19.99, three agreed rolls of 50 mm by 50 m. The card score is 91, shown as 9.1, from 4.8 and 276 reviews. It is the best square-metre price among the other rolls with at least 50 reviews and one agreed length. The listing states −20 °C to 180 °C with no standard and no micron. Skip it if you need a 110–120 °C datasheet. The roll at about £3.45 is the lowest shelf price and only 10 m, so it is not best value.
BOMEI PACK aluminium foil tape, 3 × 50 mm × 50 m
Best square-metre price among the other rolls with at least 50 reviews and one agreed length: three rolls of 50 mm × 50 m at about £19.99.
