for EWI insulation, what are the pros and cons of
a) insulating over the externally running gas pipe after protecting it by a larger diameter steel pipe rather than
b) extending the gas pipe to run on top of the insulation?

My kneejerk reaction is that b) is a poor choice because the copper pipe will act as a cold bridge and because due to thermal expansion outside of the insulated envelope it is more likely to develop a leak.

Opinions?

Many thanks!]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17968&Focus=303481#Comment_303481 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17968&Focus=303481#Comment_303481 Fri, 22 Sep 2023 11:30:35 +0100 Peter_in_Hungary http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17968&Focus=303504#Comment_303504 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17968&Focus=303504#Comment_303504 Sun, 24 Sep 2023 14:57:31 +0100 revor I have observed gas pipes going up to say 1st floor of a building and are covered by a capping part way presumably to deter vandalism. That is what I think common sense would dictate.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17968&Focus=303734#Comment_303734 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=17968&Focus=303734#Comment_303734 Thu, 05 Oct 2023 09:17:25 +0100 blubb
It turns out the building regs allow the gas pipe to be covered provided it is protected by a steel pipe against mechanical damage.]]>
