    Before brexit, I was eyeing up baunativ.de for some more AT tape. I've just been to look again and I'm sure that Profil has jumped from 18 euros to 24.. Throw in a 20% punch on the nose for the new forex rates and these tapes are looking a tad pricey.. Though .de does still beat anything I can find here..

    Anyone got a good source for them, foreign or domestic?
  1.  
    Baunativ has been the best price I have ever got.
  2.  
    I paid 19.1 Euros for 60mm Profil in June 2015. Full price was 28.5, and they showed a 33% discount on 6 rolls. Does your price incl any discount?

    24 is the discounted (2% off) price for 6 rolls :o
  3.  
    2% off? I wonder why I got 33%?! Oddly enough I did not get any discount ('rabatt') on 18 rolls of Tescon, while I did on 45 rolls of Uni Tape and (inexplicably) on 6 rolls of Profil. I did spend nearly 1400 Euros, so maybe that was it. In Feb this year I got 31% discount on 10 rolls of 60mm Uni Tape.

    Well, if you still have some that you want to sell... :)

    Vana seems to be 18 a roll.. I guess a machine lightly running a Stanley knife down the back of 30m of tape is worth 8 euro all day long.

    . I guess a machine lightly running a Stanley knife down the back of 30m of tape is worth 8 euro all day long.

    It'd have to be *very* lightly!

    I think I only have one roll of Profil (Edit - I checked - It's about one-and-a-third rolls). I do not need it, but prob not much use to you.

    I actually only need a small amount of profil (I was going to buy two rolls, but 1.3 would do it) for awkward connections around things like existing steels, I can get away with unitape for the rest (and I prefer it - knifing up profil and then using the Stanley blade to pick the backing off when wearing gloves, while up a ladder, while holding a run of membrane with my head to stop it dragging the orcon all over the place, ain't fun. Unitape being peel n rip is much better, twice as fast at least

    Can we really not yet buy airtightness tape at builders merchants yet? I can't believe that this is still specialist item. Every damn building must need some taping - surely builders need to buy it by now to meet regs, or are we still all obsessive wierdos?

    None at TP? Screwfix? Toolstation?, Ridgeons?, Wickes?, Jewson? etc?

    None of Siga, ProClima, Isocell, Dafa/Isover, Dupont, Unger-Diffutherm (that's 6 manufacturers - there may be more) available in a bloody shop!

    No-one found a local source in Cambridge yet?

    Also when I first bought profil it had two tear-off strips so you could use it 50:50 or 25:75. Are those options still available or is it only 25:75 now (all my recent tape has been like this).

    (And yes I've run out and resent the fact that I need to order a week in advance!)

    I think if you ask for air-tightness tape in J--kins or Tr---s Persons you'll get foil tape at best. Ditto Sc---f-x and Tr---point AFAIK.

    I'm not sure of the current situation, but I know it changed for the worse whilst I was building. Also there are types of profil available on the continent that are not imported here. I switched to the Siga equivalent for some things. And Siga is available locally to me - in a village somewhere near Sudbury, IIRC.

    If you were one of the 99â„… of builders who don't take advice from this forum and still believe air tightness is something to be avoided rather than sought.

    If you buy tescon profil from baunativ.de then you get the 3-tape flavour, although the spacing is 40:40:20, not the 25:25:50 I had before. And it's light blue rather than dark blue. But delivery from Germany costs less than from ecomerchant (Bristol?), which seems a tad perverse. Funny old world. Lower-carbon to get it from the UK, I suppose.

    Probably not, since it's been to Ireland first.

    "With air tightness being a Building Regs requirement, I foolishly thought that by now, at least one of the five builders merchants would stock basic air tightness products." - totally agree, but I think the answer to that is so long as a house is supposedly "airtight" on the day of the test or of BC looking at it, they don't care if it peels off 6 months or a year later. Whereas we will be living in the houses we are building so we really do care that it lasts more than a year. I think that's why foil tape etc is being offered, because the regs in effect don't seem to say anything about longevity, just the day of the build. Our mass developers have only ever built to the absolute minimum they can get away with, and since millions of folks are daft enough to queue up with their cheque books to buy those houses, there's no incentive to change.

    I'm assuming that bulk transport to the merchant is more efficient than the one-or-two tapes posted to me, so minimising that last stage would be best. I could be wrong. Low-carbon distribution is a large subject.

    Most of them haven't got much choice. An office co-worker who is just psyching himself up for buying a house (in/nr Cambridge) was grumbling that he resents paying a truly stonking amount of money for something that he knows is likely to be shoddy. But he's not really the sort to want to self-build, and self-build plots in/nr Cambridge are hard to come by so it would take years, even he was keen.

    The current govt have at least tried to make self-building easier and more normal, so I guss that is (a bit of) progress

    He doesn't have to, but I think that there are more of those available than old houses. I'll ask him why that seems to be an assumption.

    +1 for this. At first I thought the roll Nick sent me had faded in the sun or something, as all my profil was 25:75 and dark blue when my UK guy sent it, but Nick's (and the extra roll I ordered from baunativ when I got the Unitape) was light blue (and 3 part and as you say, more like 40:40:20)


    The current government at least now acknowledge that the biggest barrier to self build is administrative: planning departments that say no and to a greater extent, mortgage providers that say no

    All the "forcing councils to make self build l;and available to anyone who wants" in the world will do no good if the anti-self build culture persists in the financial world

    I've got a guy (regular builder) in doing some work for me at the moment, and he looks at all the airtight membrane and taping detail in amazement, shakes his head and says "if you hadn't got into all that bollocks, you'd have been finished a year ago..

    "Yeah", I said "but then I wouldn't have a 280 square metre conversion with 100sqm of glass, that costs me 30 quid's worth of electricity a month to run the heating system"

    "But how much have you spent on all that guff, and on the heating, and kingspan, and on a mortgage while you've not been living in it and enjoying it.."

    There'll never be agreement, of course. From his viewpoint I've spent tens of thousands needlessly - I should have just put a big oil boiler in like he did with his 4 bed detached, that had 125mm of kingspan in the ceiling and a bit of rockwool in the walls.
    And I'll always see his point, I just chose my way, and I see there's not a chance in hell that Barratt would have done the same

    Ah, sorry for that surprise. For my part I had not, till last week, seen 'UK market' Profil in the 'denim blue'.


    It's all getting painted anyway - I tape my windows to my membrane, but ultimately my plasterboards stop 10mm short of the window frame and there's a black (painted) gap all the way round to frame the window (a "shadow gap") because I like the effect and as a bonus it thermally disconnects my plaster from my windows to reduce the chance of it all going mouldy. Hopefully.

    He keeps asking me if there's a black rubber gasket that's going in the gap to finish it off..

    Some compromises have to be made when the planning insist the windows are mounted in the stonework and the timber frame inner leaf gives all the thermal performance..
