Until recently I didn't even know these sun tube / pipes / tunnel even existed. They are an excellent innovative idea but actually very simple. Sorry- I should explain- essentially a system which, through a highly refelctive tube, brings natural light from your roof (by way of a sky window or dome) into your dark rooms - normally first floor- or ground floor on bungolow (but i have also heard that it can be brought down to ground floor in a two storey house).Apparently it can be installed in basements through the wall- like a porthole!

Anyhow, I was just wondering how many people are amazed that these natural light sun tubes / pipes are not more widely known about? And trying to find a company to fit them wasn't easy either - but eventually did and they were excellent.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30932#Comment_30932 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30932#Comment_30932 Sat, 23 Aug 2008 09:07:03 +0100 Rachel http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30955#Comment_30955 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30955#Comment_30955 Sat, 23 Aug 2008 17:34:03 +0100 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30964#Comment_30964 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30964#Comment_30964 Sat, 23 Aug 2008 19:48:17 +0100 Terry as you infer performance definitely goes down with increase in length, and also with any bends.
j40 - these tubes are fairly well advertised in the building press and at shows etc. There have been a number of threads on here discussing them.
Will be fitting our solatubes soon.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30970#Comment_30970 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30970#Comment_30970 Sat, 23 Aug 2008 21:43:06 +0100 Rachel http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30978#Comment_30978 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=30978#Comment_30978 Sun, 24 Aug 2008 07:21:22 +0100 j40 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31031#Comment_31031 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31031#Comment_31031 Sun, 24 Aug 2008 21:11:09 +0100 Rachel http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31032#Comment_31032 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31032#Comment_31032 Sun, 24 Aug 2008 21:22:21 +0100 Davipon http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31063#Comment_31063 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31063#Comment_31063 Mon, 25 Aug 2008 14:45:47 +0100 j40 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31064#Comment_31064 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31064#Comment_31064 Mon, 25 Aug 2008 14:57:58 +0100 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31077#Comment_31077 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31077#Comment_31077 Mon, 25 Aug 2008 17:13:19 +0100 Terry http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31118#Comment_31118 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31118#Comment_31118 Tue, 26 Aug 2008 09:53:49 +0100 arthur http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31120#Comment_31120 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31120#Comment_31120 Tue, 26 Aug 2008 10:25:18 +0100 docmartin http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31127#Comment_31127 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31127#Comment_31127 Tue, 26 Aug 2008 13:03:35 +0100 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31131#Comment_31131 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31131#Comment_31131 Tue, 26 Aug 2008 15:02:51 +0100 j40 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31140#Comment_31140 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31140#Comment_31140 Tue, 26 Aug 2008 17:58:14 +0100 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31143#Comment_31143 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31143#Comment_31143 Tue, 26 Aug 2008 19:13:47 +0100 Rachel http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31154#Comment_31154 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31154#Comment_31154 Tue, 26 Aug 2008 20:35:05 +0100 Davipon http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31193#Comment_31193 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31193#Comment_31193 Wed, 27 Aug 2008 06:54:33 +0100 docmartin http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31978#Comment_31978 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31978#Comment_31978 Sat, 06 Sep 2008 03:09:17 +0100 Terry http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31996#Comment_31996 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=31996#Comment_31996 Sat, 06 Sep 2008 11:14:32 +0100 Rachel http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237030#Comment_237030 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237030#Comment_237030 Sun, 28 Feb 2016 18:58:44 +0000 Silky http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237031#Comment_237031 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237031#Comment_237031 Sun, 28 Feb 2016 19:38:00 +0000 Gotanewlife
The diffuser is DG but as this drops to a suspended PB ceiling it doesn't help much....I did surround mine with foam as a fixing and insulation and worked very hard on making water proof. Also note that, as mentioned above, top cover is deliberately not air tight as condensation inevitable, so runs down outer hemisphere into foam ring and evaporates away idc or overflows outside. So consider that whole tube is 'cold'

Mine are just excellent, wouldn't be without them!! Also wouldn't even dream of paying more for better engineered ones unless perhaps going PassivHouse.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237038#Comment_237038 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237038#Comment_237038 Sun, 28 Feb 2016 21:44:12 +0000 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237043#Comment_237043 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237043#Comment_237043 Sun, 28 Feb 2016 22:45:51 +0000 Silky
I'm planning warm roof, so I would place the DG thermal break within the insulation layer. The above mentioned product is also claiming air tightness. I think I will call them this week but would be keen to get some independent feedback.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237044#Comment_237044 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237044#Comment_237044 Sun, 28 Feb 2016 23:38:33 +0000 Gotanewlife
Just had a look - nice bit-o-kit! I am only dubious as to the light collection claims - the best orientation is to mount the domed collector horizontally and pass through the sloped roof vertically - which isn't an option for obvious reasons given their thermal break needs to be in the same plan as the roof. In addition, the glass thermal break will reflect light (twice!) so absolutely cannot get close to non-thermal break transmittance tubes of well over 95%. Still all-in-all looks good and not as expensive as I imagined.

If anything (dust water) falls on the DG section it'll be a bugger! Looks easy to ensure air tightness. You are certainly going to need to trust their engineering and R&D. Would I have paid more than a third more for it? - probably not but then I only have 100mm of white EPS in my roof. Reckon I could DIY the DG break without too much effort though, now I have seen the idea ]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237046#Comment_237046 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237046#Comment_237046 Mon, 29 Feb 2016 00:30:03 +0000 tony
Plastic on a roof leaves me cold insulating them is difficult, insufficient light, condensation, all downsides]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237048#Comment_237048 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237048#Comment_237048 Mon, 29 Feb 2016 07:23:45 +0000 Nick Parsons
I agree that they are not great thermally, but in terms of getting light to inaccessible places - excellent. I have not had a close look for a few years, but the one upstairs lit an otherwise unlit WC.Roughly 2.4m and a good bend to get to the roof slope, and it looks as if you have left the light on! No major condensation issues except when the local 'darlings' broke the dome.

In this case a high-performance roof-light and a 'tunnel' simply would not have worked.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237085#Comment_237085 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237085#Comment_237085 Mon, 29 Feb 2016 17:11:18 +0000 tony http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237141#Comment_237141 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=2417&Focus=237141#Comment_237141 Wed, 02 Mar 2016 08:11:39 +0000 Chris P Bacon
