algas... just phoned everest the silly moose on the phone didn't even know what a TI camera was!... she made a half hearted effort to ask someone else and came back with a negative answer!....i chose everest because their suppose to be the best + because i live near heathrow, BAA have a half price deal with Everest, and the outer pane of glass is 10mm thick (for noise abatement)!... and apparently you cannot get this spec anywhere else; even in everest (retail)!....... i too suspect that it is the outer walls causing the down draft, and will definately be installing external wall insulation once the government get their act together and introduce the "green deal" package for domestic households.
andytw... thanks for the link must research into this abit more

do you have recessed downlighters fitted?

light a smoke match in every room and see where the smoke travels to?

slightly smelly but cheap.

mcmoby69... yes i have recessed downlights fitted, but the have all been sealed up so no air gaps coming from the loft at all. tried the match trick (probably the first test i did + candle) still can't trace the problem
will have to re-schedule the window fitting as have some other plans

I have a FLIR P640 TI Camera if you want to have a play. Not sure it would find anything obvious because it sounds like you have changed or upgraded just about everything . Ideally it would be good to use in conjunction with a blower door to depressurise the house and exaggerate any leaks but I don’t have one of those. Thermal imaging is seasonal giving the best results in the colder weather. Basically the greater the temperature differential between inside and out the better the results will be. There are protocols to follow that allow the best results to be obtained. Some of these are scanning after sunset to allow any residual heat in the bricks to dissipate. Any rain fall will also delay scans by 24 hours. Strictly speaking any internal scans would involve removing any hanging pictures and moving furniture/curtains away the walls & windows at least 2 – 3 hours prior to scanning to prevent false cold spot readings. It all depends on what level of detail you are looking for.

Anyway, if you are interested then let me know.

Karl.
