Not sure how much is remaining, my guess is more than half of the 50m roll but I don’t want to roll it out to measure. If you know what you’re doing you can probably get an idea from the width that is left. This was leftover after our build and had been stored inside. Need the space now. I think it’s quite expensive to buy so selling on here for low price to get it out of our way. collection only from Epsom/Ewell KT19
