Polythene

We currently use Visqueen polythene produced in the UK by BPI.
The pricing is as follows
9.2m (30ft) wide polythene costs 17 euro per linear metre
14m wide polythene costs 21 euro per linear metre​
Delivery is 44 euro for parcels up to 40kg.
The polythene is 1000 gauge and has a UV guarantee of 5 years. It generally can be expected to last more than 15 years. It is a super material. I have made a video showing you the easiest way to cover your tunnel with this polythene.
