My Camera is low res so I only do interior work and limited exterior detailing.

The main use is in conjunction with Ait leakage testing; Incoming cold air will cool sufraces showing up air leakage paths.

I am now about to upgrade and have found that Â£4,000-Â£8,000 is needed for a camaera capable of providing reasonable images for exterior work.

---------

It is very improtant to understant that thermal imaging is a qualitative analysis and needs a good understanding of physics to interpret correctly.
For instance if you image metal and wood at the same temperature the camera will show different temp's du to the different emissivities...

It is also a profession for insomniacs as Solar radiation quickly messes up results.

Visible light :cool:

I would like to use a camera for building defects - roof leaks , under floor heating faults and for energy diagnostic work .]]> Thermal imaging cameras http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=43265#Comment_43265 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=43265#Comment_43265 Wed, 14 Jan 2009 16:59:10 +0000 SimonH
Alternatively some of the digtal SLRs are available without the IR filter I believe - check some camera forums but it was what I was considering. I think some of the older models might be available cheaply on ebay having gone out of fashion. What you then need to add is a screw on visible light filter to the front of your SLR lens and all that hits the sensor is IR. So again - you can get black and white thermal images. White is hot - and leaky - darker is cooler and insulated. The advantage with digital of course is you can play with the settings to get the exposure right so that instead of getting a black image with shadesof dark grey, you get a whiter image with shades of light grey. You can also use the camera for "normal" photography. Still expect to spend a few bob on lenses, batteries, filters tripod / bag etc.

These both won't give you temperature reading and let you work out real U values, but at least you can see where the leaks are. They are also much higher resolution that dedicated IR cameras.]]> Thermal imaging cameras http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=43271#Comment_43271 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=43271#Comment_43271 Wed, 14 Jan 2009 17:23:49 +0000 PaulT
Visible light centres around surfaace temperatures of 6,000K - the sun, the IR the cameras detect is closer to those magnitudes of temperatures rather than the 250-300K (approx) range we are interested in.

James CIBSE Guide A (Environmental), available from your library (I believe) is a good start for background reading.]]> Thermal imaging cameras http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=43431#Comment_43431 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=43431#Comment_43431 Thu, 15 Jan 2009 21:12:01 +0000 BrianR
It is well worth getting a surveyor round who offers an IR service. I paid Â£250 and it showed up all the places where radiators were streaming heat to outside. The wood framing of the house underneath the render. Places where water was leaking in from the roof and many other useful bits of information. The JPEGs supplied will be invaluable for future maintenance.

There are some things that would be a very useful addition. It would be useful to have a picture of where heat flows out of the house rather than the external temperature. Not quite sure how to achieve this (pulse heat the house?). Even better would be a service like IR that detected water or damp in buildings (in 3D). The person to lick that problem with a cheap gadget will make a fortune.]]> Thermal imaging cameras http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=93744#Comment_93744 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=93744#Comment_93744 Sun, 07 Nov 2010 22:49:01 +0000 trolleyed Thermal imaging cameras http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=93750#Comment_93750 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=3290&Focus=93750#Comment_93750 Mon, 08 Nov 2010 08:10:00 +0000 DamonHD

Livingston was very helpful 2010/07/19 saying that a typical low-end thermal camera with a USB connection to extract images from it would cost somewhere round Â£300--Â£400 for a 3-day hire which could be over a weekend, which would probably cover me. Ashtead Technology had a 2-day minimum hire for a little over Â£100/day for similar, so getting hold of this equipment is not prohibitively expensive or difficult.

(surveys beeing offered in the Leicester / Cambridgeshire / Surrey / Reading/ Swindon area for GBP 100.

I've had this service from Ivan last year and it's definately useful. We found a couple of leaky windows, a big heat hole above the bathroom vent and you could see one of the radiators throught the (Cavity insulated) wall. His camera is not the fanciest, but it does the job.

Their DG was cooler than their walls, I dont think they put any insulation in the walls.

I suspect thats fairly typical of a modern "as built" survey as building regs dont monitor what insulation actually gets installed.

The IR camera has been very useful in confirming my thoughts as to where the cold bridges are.
I plan to use it again when its windy to spot draughts.]]>
