Hi all
I'm sorting out the loft in a house I've moved into and the next job is to lag the naked pipes. There's a mixture of 15mm and 22mm.
1. What's the best foam product to use. Some day thick grey stuff is fine, others say to use Armaflex / Tuflex, and that even those won't stop a freeze in the extreme cold (at which times they say you should leave your loft hatch open to prevent freezing)? So firstly, what to buy?
2. If a pipe is clipped to a joist and will be covered by the loft insulation, should I still lag it?
3. Some pipes are clipped to the rafters or are clipped to vertical timbers. How can I insulate them?
4. We've got several outside taps, do I need to insulate the the small amounts of external pipework?
5. Pipes around the house, underfloor boards (some are accessible), not boxed in, etc. Is it a good idea to lag these where possible from an energy saving point of view? I've read that it is, but then I also think they give off heat. So that one's always confused me!
We are in rural Wales and I just want to make sure I get it right first time, so any advice most appreciated. I've also just been reading about trace heaters... Overkill or good idea?
Cheers
