bissoejosh Posted February 8, 2019 Share Posted February 8, 2019 Has anyone purchased VCL / airtight membranes recently and if so where from? I've been trying for several weeks to order through passive house systems but seem unable to do so as they no longer sell to the public direct. If anyone has any recommendations for alternative suppliers that would be great, even better if they stock Gerband products as I'm a big fan of the 586 tape. Many thanks Link to comment Share on other sites More sharing options...
scottishjohn Posted February 8, 2019 Share Posted February 8, 2019 not hard to find just goggle https://www.amazon.co.uk/Air-Tightness-Tape-Gerband-Hermetic-60mm/dp/B0767JBMR6/ref=sr_1_2?ie=UTF8&qid=1549654230&sr=8-2&keywords=gerband Link to comment Share on other sites More sharing options...
bissoejosh Posted February 8, 2019 Author Share Posted February 8, 2019 (edited) Google, why didn't I think of that. Only £36.82 a roll delivered, bargain. But more seriously a lot of people used passive house systems so I suspect there is an equivalent supplier out there that people have perhaps used recently?

ProDave Posted February 8, 2019 Share Posted February 8, 2019 I used Protec Bariair membrane from Jewsons (to order) And Tescon Vana air tighness tape from a seller on ebay from Germany, way cheaper than the UK sellers. 1 Link to comment Share on other sites More sharing options...
Russell griffiths Posted February 8, 2019 Share Posted February 8, 2019 Does anybody like the SIGA stuff it’s a bit pricey but I got to play with some the other day and it was very tough stuff. Link to comment Share on other sites More sharing options...
dpmiller Posted February 8, 2019 Share Posted February 8, 2019 They're using SIGA tapes on ours, over VC Foil Ultra. The window tape is superb, really easy. Link to comment Share on other sites More sharing options...
Cpd Posted February 8, 2019 Share Posted February 8, 2019 I used this one as I got it cheap, what an amazing tape ! Found this eBay seller doing it for about £30 a roll which is still good value for such a quality tape. https://www.ebay.co.uk/itm/SIGA-Wigluv-60-60mmx40m-Klebeband-10-Rollen/331905854819?hash=item4d47216d63:g:XpAAAOSwDNdVv2uu Link to comment Share on other sites More sharing options...

Triassic Posted February 19, 2019 Share Posted February 19, 2019 Lots of suggestions for tape, any suggestions for the vapour control membrane? I only ask as I need enough to cover 1000m3 house! Every Pound saved counts! Link to comment Share on other sites More sharing options...

Every Pound saved counts! vcl --goes on inside --thats the one you NEED to tape do you you mean breathable membrane for outside?,that one most systems are happy just with big overlaps and stapled down not taped ,as it has to breath not seal you need both Edited February 19, 2019 by scottishjohn Link to comment Share on other sites More sharing options...
Triassic Posted February 19, 2019 Share Posted February 19, 2019 (edited) Outside membrane is fitted. I’m now looking for inside VCL. Edited February 19, 2019 by Triassic Link to comment Share on other sites More sharing options...

Is there really any good reason that dpm can't be used? 40p/m2 It may be tricky to lift a wide roll into place but then is forever pinned onto joists and in the dark There is a considerable premium for the stuff sold as wall vapour barrier (and with writing on it to prove it). (£1.80) 500m2 at £1.40 difference? = a lot, if there is no clear advantage. I know some experienced builders here use the fancy stuff, so there has to be reason. Looking forward to the answer.

Cpd Posted July 9, 2021 Share Posted July 9, 2021 (edited) For my vcl I just use light weight plastic sheeting designed for this purpose….. it’s really easy to handle and is a lot cheeper than DPM Edited July 9, 2021 by Cpd 1 1 Link to comment Share on other sites More sharing options...
saveasteading Posted July 10, 2021 Share Posted July 10, 2021 23 hours ago, Cpd said: light weight plastic sheeting Thanks. found it, I think, at 10p/m2 which is 30p less than dpm and £1.70 less than the yellow make with writing on it. Over 500m2 that is saving a lot. Now if only I can get all the other materials at 1/18th of the advertised cost. But it is 32 microns, which is 0.03mm. This seems to be 3 times the thickness of clingfilm. is it strong enough? presumably stapled into timber. like this?

Cpd Posted July 10, 2021 Share Posted July 10, 2021 Sounds grand, it’s all pretty straight forward and it’s easy to work with, tape the junctions and try to put them where they will get sandwiched between frame work and battens or plasterboard. I have seen it in both semi transparent clear and semi transparent green…… not sure what the difference is beyond the colour ! Link to comment Share on other sites More sharing options...

I was going to opt for the intello stuff, but locally 10 rolls of VC foil ultra have came up quite cheap at 600 quid and was maybe going to opt for that with some good tape.

dpmiller Posted November 11, 2021 Share Posted November 11, 2021 It's good stuff- it's heavy, really doesn't want to tear, and folds and tucks well. 1 Link to comment Share on other sites More sharing options...

Don't know why I am holding back though on it and trying to talk myself into the intello from Germany. I was recently looking at this to understand the airtightness properties of my EPS roof. I was very surprised by how low the water vapour resistance rating was for Pro Clima Intello Plus. It made me realise I don’t understand this topic. Obviously the Intello allows the wall/roof to breath. Whereas DPM or TIMco DPS504 or VC Foil Ultra are practically air tight. But what is the outcome we are looking for?

Obviously the Intello allows the wall/roof to breath. Whereas DPM or TIMco DPS504 or VC Foil Ultra are practically air tight. But what is the outcome we are looking for? That is causing me the issue here - the price of the intello is I think around 40% more, not inconsequential when you need a lot of the stuff. Then I was trying to understand the differences and if I really needed the intello. But it makes perfect sense that you would want any vapour out the walls and back into the house in summer to stop condensation in there, but I assume the VC foil just doesn't do that. Only intelligent VCL's do. It especially worries me as I have a SIPS build and interstitial condensation would be a major issue. But similalry...im pretty sure hardly anyone in SIPS is using an intelligent VCL. Are the sales tactics preying on my overthinking? Link to comment Share on other sites More sharing options...
