Such panels would only provide excellent insulation if they had a good thermal seal top and bottom and sides.
Has anyone here any experience of designing this sort of feature, or any advice on detailed design?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13255&Focus=222010#Comment_222010 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13255&Focus=222010#Comment_222010 Mon, 30 Mar 2015 15:01:47 +0100 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13255&Focus=222232#Comment_222232 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13255&Focus=222232#Comment_222232 Fri, 03 Apr 2015 15:36:25 +0100 djh Posted By: collonachSuch panels would only provide excellent insulation if they had a good thermal seal top and bottom and sides.
I did quite a bit of research early in my design process but in the end I haven't incorporated any of it!

There are quite a few external shutter systems around. One of the German housebuilders - Baufritz? - builds big external sliders. The problem I see with external shutters is dirt and leaves etc clogging either the seals or the mechanisms, plus designing for wind loads. So I'd definitely recommend using an existing proven design if possible. I was tempted more by internal shutters but the extra expense and complexity didn't seem worth it at the final cut.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13255&Focus=222312#Comment_222312 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=13255&Focus=222312#Comment_222312 Sun, 05 Apr 2015 16:58:56 +0100 ferdinand2000
If it takes a minute to close each one, you will need to be dedicated to operate a dozen twice a day.
