Anyone used Infrared ceiling film?

[MontyVeda]

I have an infrared panel which works well. The heat radiates out from the panel and only warms objects it touches rather than heating the air.

Infrared ceiling film is designed to go behind the plasterboard... but how i imagine this working contradicts the point of infrared heating, unless I've got it wrong.

I imagine that the IR film radiates heat into the plasterboard, the plasterboard becomes a thermal mass and from there it's convection through the air.

OR... does the IR film radiate through the plasterboard and the heat radiates through the air to heat the objects below?

I don't see that it's radiating anything if it's enclosed in the ceiling, isn't it just heating the ceiling which then radiates heat into the room?

If you think hot ceilings are a good idea, you might be interested in this:

(Ref: Chartered Institute of Building Services Engineers, Guide A)

Radiant temperature asymmetry causes thermal discomfort, and hot ceilings are the worst culprit. I can't say I'd be very keen on having my heater embedded in the ceiling either when it comes time for some maintenance or repair, but then, there are those who embed their heaters in floors.

I always thought heat rises. So in a two story house a downstairs ceiling might be putting more warmth into upstairs than downstairs?

That works pretty well overall. I have twice owned top floor flats and my heating bills were very low

Heated ceilings are the work of Beelzebub (although they do have their uses in hospitals where cleanliness outweighs their inherent satanic nature).
And if you're sat under one, at a meeting for example, your head fries while everyone else whines about being cold.
