Airtightness tape choice

[Crofter]

I've just started replacing a couple of windows. Previously I'd used SIga Wigluv black tape, and I can confirm that after nearly ten years it's still perfectly adhered and has done its job perfectly.

It's flippin expensive though.

I can get e.g. Illbruck ME315 for a third of the price, and it also seems very highly regarded.

 

I'd be interested to hear what tapes other people have used and how you would rate them.

Tescon Vana tape bought from LATZEL Dämmstoffe. Was about €20 a roll when I last bought.

Is Vana the same as Pro Clima?

Pro Clima are the manufacturer. Tescon Vana is the product. there's other's in the line that deal with different things, like around windows we used the Tescon Profil. if you do a quick search on here you'll find a wealth of information!

I used Gerband products from PassivHaus Systems but then needed some extra and they didn't have the Gerband in stock - I went for the own brand PHS stuff and it seems absolutely fine if not quite as good as the Gerband stuff. Only limitation is minimum order quantities. 

[Crofter]

Oh well in the end I've chosen Illbruck me315, because the places selling the other stuff all wanted silly money for delivery (of a single roll of tape) to a Highlands postcode. 

Hopefully it'll be up to the job.

We’ve used both Gerband and the own brand PHS stuff including their spilt release tape for windows.  Happy with both to be honest.

Have you bought it? I have about 20 metres of ME508 available (100mm depth).

I've ducked out of purchases that require this, even if getting it delivered to SE England.  And told them why.

Of course they have no idea that Inverness has roads, and a railway,  let alone an airport. 

I suspect some of them are profiteering, but most are in need of geography lessons (or their chosen couriers).

Already bought but thanks for the offer 😊

It's so frustrating. 

Parcel force deliver to here at a decent price, and obviously anything royal mail is a fixed rate. But so many companies ignore these options. 

 

I swear that when I was doing the build, I spent more time trying not to get shafted on delivery than I did actually building! 

 

One little good news story though- yesterday I phoned a supplier for something and they agreed to cut their stock 2m length down to the 1.8m I needed, which dropped it down a price bracket on delivery. Order went from £93 to £52 with a single phone call. Very decent of them.

This stuff looks identical to the stuff I used but a different brand. 

 

It doesn't look fancy but i was very impressed with it in person. Better than the Belgatape and Tyvek tape. I've used it externally on the garage too and it survived the weather for 6 months before I clad it.

I've also used PassivHaus Systems own branded tape and found it very good.
