can we choose less branded items but get the same result?

Hello,architect specified dearest materials on the plans inclding intello plus air tight vapour control membrane and proclima tescon vana tape. 

Can we use something less high spec like PHS astra membrane instead?

if you buy Intello Plus and Tescon Vana from Germany it's a LOT cheaper! the intello plus is damn good stuff. really tough as well and the Tescon Vana tape is super sticky and definitely recommended. around the windows you'll probably want to use the Tescon Profil as it's split to give you the return on the window edge. personally on the airtightness stuff i wanted the best products so i bought the best. obviously everyone has different requirements!

 

bought mine from Latzel Dammstoffe and can definitely recommend them.

Us too - brilliant to deal with.

Thanks, much appreciated. So even roughly on a house thats 194m² roughly how many rolls of tescon vana tape and tescon profil would you think?

[MikeSharp01]

We have 157m2 ( close to 500m2 of wall and roof) and we brought 16 rolls of vana, 2 of profile, only need enough to go around all the windows, and 3 of the 4m wide ( that's a lot but we have about half a roll over) Intello plus.

cheers Mike.

I'm looking at airtightness tape now too, is there any reason why I should use the Tescon over this stuff? https://passivehousesystems.co.uk/product/gerband-586-airtight-tape/?utm_term=&utm_campaign=P-Max+Test&utm_source=adwords&utm_medium=ppc&hsa_acc=4901615203&hsa_cam=20355723828&hsa_grp=&hsa_ad=&hsa_src=x&hsa_tgt=&hsa_kw=&hsa_mt=&hsa_net=adwords&hsa_ver=3&gclid=Cj0KCQjw2qKmBhCfARIsAFy8buK_6Os1ItUfZI-IGCyuty8_T91HUY4t783aNEKLQRPHaEp4tvBgUfgaAmgUEALw_wcB

 

Any one used it before? Only £10 for a 6cm x 25m roll
