Expanding foam is useful stuff but not the universal solution that much of the building trade now seems to use it for.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305569#Comment_305569 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305569#Comment_305569 Tue, 19 Mar 2024 09:37:51 +0000 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305589#Comment_305589 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305589#Comment_305589 Fri, 22 Mar 2024 08:03:54 +0000 chrisinbrighton Expanding foam is used as a cheap loft insulation just below slates-does this degrade?
Im hoping because its a reroofing old building they dont need mechanical fixingd]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305590#Comment_305590 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305590#Comment_305590 Fri, 22 Mar 2024 08:40:34 +0000 GreenPaddy

If one comes off, and trashes a car, or someone's head, the judge may ask why Mr Bodgit thought foam was a good idea ]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305591#Comment_305591 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305591#Comment_305591 Fri, 22 Mar 2024 10:06:47 +0000 djh
See https://www.gov.uk/government/publications/manual-to-the-building-regulations :

"Most building work carried out in England must comply with the Building Regulations. The legal term ‘building work’ generally includes ... ‘Renovation of thermal elements’ is also building work. This includes roofs or external walls. Those responsible for carrying out building work have a duty to meet the requirements of the Building Regulations."]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305594#Comment_305594 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18106&Focus=305594#Comment_305594 Fri, 22 Mar 2024 19:34:48 +0000 chrisinbrighton Originally the ridge tiles were held on with lime motar and have lasted over 100 years. I can see that building regs for some things can be tweeked if its an old listed building.
I looked at the mechanical fixings but with the ridge tiles I have (crested terracotta,no overlap) it seems dodgy having a stainless screw giving a lead in for water.

I accept expanding foam is a bodge!]]>
