Insulating pipes

[HawkWhiteFinger]

Is there much call for insulating central heating pipes underneath a downstairs floor?

There's not an awful lot of clearance to actually get the grey foam type around the pipe, so if I must, then my options are quite limited.

Nah

So no heat waste or risk of freezing?

You asked if there was much call for it. 99% of the houses I work on don't have lagged CH pipework.

If under floor is vented then it's same as being outside! Even plastic needs lagging, IMHO

I always lag under floors with 22 x 19 or 15 x 25mm. More expensive than the copper.

Yes, being downstairs its vented. JC obviously didn't realise I said downstairs.

Climaflex seems to get more and more expensive (or maybe i'm just getting older)

As Tamz mentions .. thick stuff is the way IMHO .. don't bother with the cheap stuff although it's better than nothing at all!!

I once met an insulation company lorry driver at a snack bar and bought 4 boxes for £80 (that is all the cash i had on me). Wish i could meet him again:smile:

Just went to help a guy out with a quote .. 2 1/2" Iron to be lagged!! Thankfully he's doing the pricing How come it costs so much yet you'll get ziltch if you weigh it in?

B and poo seem to be the cheapest place for insulation at the moment. Especially if you've got a trade point card.
