Pipe Insulation Regs?

[kevnurse]

Hi guys,
The lagging on my pipes in my loft (2 bed bungalow, N Scotland) is the old brown felt stuff and needs replacing. On the racks in my local supplier I noticed 3 different thicknesses of foam insulation for 15mm and 22mm pipes. Before I commit to buying the insulation, is there any British standard thicknesses I should comply with? Is there, say, a table of foam thicknesses for pipe sizes dependant on regional location and internal location (in the house). Or is it a case of local knowledge?

Thanks
Kev

Get the thickest one - the small additional cost will be nothing compared to repairing the damage caused by a burst pipe.

Interesting link.
But which thickness needs to be complied with?
Thanks.

What that table shows is required thickness dependent upon type of insulation but it doesn't give you the type,that's somewhere else.

Rigid phenolic (kooltherm) has W/m.k of less than 0.02
Bog standard foam (climaflex,bandq crap) is 0.035-0.04
