Stove floor_backing plate. Alu, steel, tiles ..

[jona]

There are serveral options for the floorplate for a woodstove, but when i ask the shops about they all say 'yes, it work foor wooden floors'. I have my doubts so i ask here.
What is a good floorplate (lower the price happy me).

Somehow i feel alu 3 mill is a good option as alu bounces the heat back and that also covers my next q'n as for the backing plate.

Stones are not an option due the weight issue and isolation wool is not ideal due to the toxic fibres so again i thought 5 mill alu will do the trick, but im not sure.

I love to read your day to day experiences what works and what not based on your everday life experiences.
