I know, looked at lots of search results for this but could not find what I was looking for.

I just boght a TSL grp A spec downpipe and want to wrap it.

Now I need to know how much I need, 1"x15', 2"x15' or does it need to be longer?

 

I wrapped mine last weekend and used 2"x25' and it did the job nicely, overlapping each time

 

Where did you get yours from?

 

2" by 25ft for me too....

E-Bay, was £25 including 4 steel ties
