I'm building a large built-in that covers a whole wall between the fireplace
and the back wall of the house. To one side of the roughly 8 foot span is a
hot water radiator, which is 4 feet long. It's a "modern", 1 foot high tyoe,
not a big cast iron model. The built-in goes up and over the radiator, with
about 5 inches of clearance below the cabinet. It doesn't get insanely hot
in the cabinet, but I do want to route as much of the heat forward as
possible.
I've thought about designing a curved deflector to curve up from the wall
right at the radiator, then curving forward under the cabinet, in hopes of
diverting the heat to some extent. I also thought about insulating above the
deflector, as well as covering the deflector itself (possibly .032"
aluminium) with shiny foil to help reflect the heat.
Has anyone had any experience with this sort of thing?
thanks,

I've done that over a wood stove. Stainless steel with air-space or
insulation behind.
MUCH MORE IMPORTANT! Contact your local fire dept and insurance
company and ask them! If they veto it, can it.
I'm pretty sure any plastics e.g phenol is gonna be real expensive

Well, I wouldn't expect such common sense from Colin & Justin.

You can buy shiny foam stuff on a roll from B&Q designed to go behind
radiators & reflect heat.

Rather than focusing on reflecting the heat (IR), concentrate on smoothing the
air flow. Those heaters run on a max of 90 degrees C, so IR doesn't play much of
a role. Convection air current does make a huge difference.
If you allow air in at the bottom, and with a curved/shaped smooth aluminum
deflector, direct the air out from the cavity, the convection air flow will take
care of the rest.
Insulating it from the cabinet above, might be a good idea if that is where you
keep your chocolates or antique LP record collection.

I have seen this done with a flat piece of sheet metal. They insulated
behind it with some aresol foam. It was very simple. I don't see the need
to do anything more complicated.
