Live in top floor flat. Have removed excessive boxing around communal
stack pipe (that goes through my flat from roof down to sewer) in
order to make space for much needed cupboards.
However, stack pipe (some 4 inches diameter and made of cast iron) is
attracting much unwanted condensation due to being so cold! Obviously
I need now to insulate it, hence this post and wish to seek advice as
to best way to proceed.
My thoughts so far are :
1. Just box around like before but much smaller boxing to allow for
2. First insulate stack pipe with Screwfix "Spiral Wrap" page 457 of
catalog 89 item 62194-89 - which is a kind of self adhesive foil
covered bubble wrap, then box around.
3. As 2 above but then add a covering of aluminium foil tape on top
of the spiral wrap to help prevent water vapour ingress using
Screwfix "Aluminium Foil Tape " page 162 catalog 89 item 15089-89.
Ideally would like some purpose made insulation sleeve to fit around
and cover join with foil tape. Does anyone supply this?
Thanks in advance for your help and interest.
