Attached is a detail I'm working on that incorporates this but I have the added problem of a void underneath the insulation due to the structural design (a suspended raft slab).

Do you think this void, and hence access to the underside of the floor insulation, poses a problem with regard to vermin? How tempted would little creatures be tempted to burrow into some warm EPS I wonder?

And if I need to protect it do you have any suggestions? Some kind of board pinned with the rods to the underside perhaps?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170376#Comment_170376 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170376#Comment_170376 Fri, 15 Mar 2013 18:31:55 +0000 Milk_No_Sugar https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170377#Comment_170377 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170377#Comment_170377 Fri, 15 Mar 2013 18:36:15 +0000 Shevek
Close knit mesh is great idea. Cheap too. Only problem is steel would eventually rust living in such a damp air void.

Think you mean this one:

If only there were some kind of super-strong rust-proof mesh available?

Perhaps one method would be to go down a metre deep with the concrete pavers around the perimeter (11 m in my case)? Problem with this is that gaps would no doubt open between the pavers, plus something will probably dig 1 m down eventually.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170385#Comment_170385 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170385#Comment_170385 Fri, 15 Mar 2013 19:06:42 +0000 Nick Parsons https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170386#Comment_170386 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170386#Comment_170386 Fri, 15 Mar 2013 19:08:51 +0000 Shevek https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170387#Comment_170387 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170387#Comment_170387 Fri, 15 Mar 2013 19:10:53 +0000 Shevek
40 mm Foamglas bottom layer perhaps?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170432#Comment_170432 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170432#Comment_170432 Sat, 16 Mar 2013 10:20:21 +0000 Milk_No_Sugar Posted By: ShevekI think even stainless steel will eventually rot, given that it'll be a damp air void with oxygen.

Actually, this was in another discussion here as well. It's oxygen that prevents SS from corroding, forming a layer of chromium or something at the surface. SS would be expensive though.

If I coudn't afford SS I'd take my chances with galv wire mesh, perhaps increasing the galv layer by spraying with galv spray (standard item in any electrical wholesalers).]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170433#Comment_170433 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170433#Comment_170433 Sat, 16 Mar 2013 10:30:25 +0000 fostertom https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170438#Comment_170438 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170438#Comment_170438 Sat, 16 Mar 2013 10:39:48 +0000 Shevek ]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170440#Comment_170440 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170440#Comment_170440 Sat, 16 Mar 2013 10:45:09 +0000 Shevek Posted By: Milk_No_SugarActually, this was in another discussion here as well.

Would cost us £234 for the amount we need:

Think I'd be more inclined to go with the Foamglas than the stainless steel given that the Foamglas is guaranteed not to degrade. Although attaching 1200 x 600 sheets to the underside of our suspended slab will be a bit of a mission.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170448#Comment_170448 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170448#Comment_170448 Sat, 16 Mar 2013 11:43:44 +0000 WillInAberdeen
I would start with an expectation that mice will get in, and choose material s that they are less inclined to shred. Eg rockwool seems less chewable than PS.

For EWI, remember that mice climb and get in above ground level as well as below. I'd use a band of mouse resist ing material round the lower part of the walls, say for the first 30 feet.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170456#Comment_170456 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170456#Comment_170456 Sat, 16 Mar 2013 12:09:30 +0000 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170461#Comment_170461 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170461#Comment_170461 Sat, 16 Mar 2013 12:36:40 +0000 fostertom Posted By: fostertomLeca.

If you lay sand blinding on top, the mice won't be able to feel your broken glass just as the clayboard doesn't! Especially if you then put some polythene on top and some nice degraded soggy cardboard (i.e. clayboard) that they can walk on and chew and make into nests etc.

So probably best to keep them out, or perhaps try leaving some poison bait down there.

Perhaps ask Dufaylite if they know what works?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170732#Comment_170732 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=10313&Focus=170732#Comment_170732 Mon, 18 Mar 2013 13:46:54 +0000 Shevek http://www.greenbuildingforum.co.uk/forum114/comments.php?DiscussionID=10330]]>
