Whilst conservatories obviously don't lend themselves too well to winter us e we do nevertheless (have to) use ours on occasion. With a wet radiator an d a radiant electric wall heater it can be made quite comfortable on even t he coldest of days.
However, whilst we don't feel any drafts in there I have noticed that with the doors to the house closed and the door trickle vents open there is quit e a draft travelling through the vents hence I am assuming that this air mu st ultimately coming in from outside the conservatory.
I am therefore wondering how best to test for where these leaks are occurin g? There are numerous points at which it is not possible to visibly confirm whether there's an air path between, say, the frame and the roof for examp le.
I'm thinking some form of smoke bomb/pellet would be my best bet. If so, an y recommendations or alternative suggestions?
