Radon and other membranes

[Triassic]

I need to buy radon membrane and the price at my local BM is a bit steep compared to on line. Can anyone recommend any of the online sellers, or is it a cast of pot luck.

 

I'll also need a vapour control membrane, again, any recommendations.

Not sure about "vapour control" but for air tightness the cheapest I found was Protect Barriair

[Triassic]

Sorry, my mistake, I meant air tightness.

 

Oh and not forgetting Radon.

Cheapest I could find (bought in the summer)

Radon Gas Barrier Roll 300MU BRE Certified 25m x 4m £62 inc delivery and VAT.   lbsbmonline.co.uk

 

Local BMs took the piss.

My local BM quote £120 +vat for 100m2, hence my question. 

 

Oh and they don't have any air tightness membrane or tapes on stock.

[oranjeboom]

£120!! Well I've saved you 1/2 then!

 

Let us know if you find any deals on air tightness tapes. Looking for some myself.

I bought from this seller in Germany on ebay, works out about £14.50 per roll http://www.ebay.co.uk/itm/20-Rollen-proclima-TESCON-VANA-All-round-Kle-be-band-30-Mtr-x-60-mm-/381452848613?hash=item58d05c8de5:g:DG0AAOSwwbdWMxxx

 

Better than the £20 or more per roll that all the UK sellers charge.
