Does anyone know of a builders merchants or similar that will sell breather
membrane such as Tyvek or Permo by the metre off a roll, rather than me
having to buy 50 metres of the stuff?

I'm close to completing the roof framing of a 3m x 3m extension, and don't
want to have to buy more than I really need (am already dangerously close to
my original budget).

(Alternatively - if anyone has about 15 sq. metres left over from another
project that they could happily part with, I live on the Bucks/Oxfordshire
border and would be happy to travel (1/2 hour) to take it off your hands!)

All recommendations gratefully received. Cheers
