Heating my home; DIY Heat shield

This is before I mounted the heat shield. The wall would get very, very hot. I was really concerned about spontaneous combustion.
Next thing I have to do is install a tile floor for the wood stove.

Here you can see the heat reflecting wall I made behind the woodstove. It is two 4X8 sheets of cement board with tinfoil I glued to them. The tinfoil is standard weight and 18 inches wide. The tinfoil reflects the heat back into the room. It does not even get warm to the touch, stays cool. Made a very significant difference in heating my house.

This is how the cement board heat shield is mounted to the wall. I used 1 inch ceramic electricity insulators. This allows an airspace between the wall and heat shield.

Great idea! How is the WAF though?

Side benefit: Alien mind-controlling transmissions are blocked by all that foil.

I wonder if silver'd paint would work as well? would result in a much nicer smoother finish. also what about GOLD metallic paint. would add better and warmer color to the room as well.

VERY cool idea man !

Last winter I did not have the tinfoil glued to the cement board. It was just folded over the top and the bottom. Man, was it ever noisy. When the ceiling fan was on the moving air would make the tinfoil flap and flutter.

Well, my idea here was based on the roof decking I have. It is the Techshield brand. It is roof decking with foil on the underside. Actually reduces the amount of radiant heat entering the attic space.
There is a radiant barrier paint available, it has metal flakes in it. Costs a lot.

I rather like the wrinkled finish.

I am not married.
My girlfriend says she likes it. She helped me glue the tinfoil on last weekend.
We used Dap Contact Cement.
Really high VOC's. Took 4 days for the fumes to go away.

Very clever idea. I might steal your idea for a gas wall heater in my living room. I know about the wall getting HOT. Put my hand on the wall and it about burns. Good safety tip. :thumb

I originally thought the cement board would be good enough. It did prevent the wall behind it from getting hot. But the cement board itself was absorbing and retaining a LOT of heat. That's when I had the idea to try tinfoil.
I just used one 18 inch wide strip from top to bottom. It was incredible. The part of the cement board that was covered by the tinfoil was slightly warm to the touch while the uncovered portion was very hot.

How about some R Max? It's foam board, 1/2 in thick. Comes in 4 x 8 sheets. Coated both sides with foil. Find it at Lowes or HD. Works well.

You don't want to use foam board around a heat source like a fireplace or enclosed fire box,
you migne go up in flames. The Cement board will retain heat when the fire goes out. You
may want to double layer the cement board and use a heavy reflective foil. I use a product
called Tempshield Reflective Insulation , this is heave fiol and has a 97% reflective value. i used it in the attic to help keep my house cooler in the Summer and it works great.

Hmmmmm. I would be very hesitant to put a flammable material near the woodstove. Even with tinfoil covering it.
