Tony recently found himself frustrated with downlighters when asked to help change a lightbulb at a friend’s house while collecting some tools for the library of things. As he removed the old bulb he was shocked at the draft that was coming out from the ceiling. It was almost like having a window open and it was just one of 16 downlights in that room.

It’s not difficult to draftproof downlighters if you do it before they are installed because it is possible to provide a box or enclosure to house them in. Sadly there is little or no possibility of doing that once they have been installed. In the past, with incandescent bulbs, downlights required careful handling due to the heat they generated. However, the advent of LED luminaries has made it easier to fit boxing over them without risking overheating.

In a house it's a good illustration of the need to keep airtightness continuous between floors - i.e joists poked into holes in the exterior wall don't cut it any longer!

I think I'd prefer to see an airtight box fitted over the top of the downlight. Easy enough in a bungalow but a bit more faff downstairs in a house.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305240#Comment_305240 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305240#Comment_305240 Sat, 10 Feb 2024 06:45:56 +0000 cjard
Go loft side and fit a fire hood. If you can't access loft side, pull the fitting out of the ceiling and seal it up or replace with a fire or IP rated one that is already sealed up by design]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305284#Comment_305284 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305284#Comment_305284 Tue, 13 Feb 2024 18:04:46 +0000 Simon Still

I see that a lot already, it is not such a bad draught but none the lees it is a draught.

The ones I've seen do seem to have a rubber/silincon ring seal on the back of the bezel.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305338#Comment_305338 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305338#Comment_305338 Fri, 16 Feb 2024 23:51:41 +0000 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305339#Comment_305339 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18085&Focus=305339#Comment_305339 Sun, 18 Feb 2024 08:46:08 +0000 cjard
