Posted a while back about thermal/FLIR cameras. Loaned one out for the weekend from Library of Things., picked up from Crystal Palace library. Worked out at £22.50 for best part of four days (planning to use for some work stuff too).
Interest to actually see stuff I'd suspected, and the main culprits to prioritise/balance with cost. In my case windows are double-glazed, but there's no thermal bridge on the frames, so the metal frames are essentially radiators for the world. It's got me thinking about specific insulated curtains to baffle the frames, magnet into position, and stop the heat exchange. It also highlighted a few spots I didn't know about, like missing caulk on skirting board/insulated wall which was leaking cold into the living room, and a draught under front door.
Would recommend, but note that the screen shows a constantly shifting temperature gradient across the colours, so you can't compare two pictures like-for-like. Use the temperature gauge as your baseline. It's very easy to get distracted by contrast in the visuals, rather than where you can make the most difference.
