So I want to insulate my liner myself. How do it do it?

I received some good advice from a chimney sweep regarding sliding an insulated flue liner into a masonry flu.
Get a roll of aluminum flashing unroll it and slide it flat into the masonry flu on two opposing sides; The chimney liner with the insulation and chicken wire over it will slide over the aluminum flashing not get caught on the masonry and easily will slide down the flu.
When I put my rigid lighter into my masonry tile flu I went one better - I over-wrapped the liner and insulation with aluminum flashing ( unrolled the 28 inch wide flashing and laid the insulated flu liner on top of it and wrap the aluminum flashing around the flu liner in one piece with one long axial seam). I secured it with stainless steel wire ties every 1 foot or so over which I put aluminum tape. The tape was meant to keep the edges of the aluminum wire from getting caught on anything. Although, after twisting the stainless wire I talk to the tips down toward the aluminum flashing. I also ran one long strip or too long strips of aluminum tape along the axial seam.
Just something I've heard about and done that might help someone else, pass this on if you like.

 

Not a bad tip, thanks. My liner has been in for a few years now but I'll remember it if I ever do another one. Mine actually went in pretty easy and the metal netting didn't really grab on to the masonry too much. Tight fit for sure though, 5.5" liner with 1/4" blanket in a flue just barely over 6".
