Hello, first post, don't know if I got the section right tough..

Basically I was wondering, if the efficiency of radiant barrier (for home insulation or industrial, high T) could be improved with different surface geometry eg wavy, triangular, pyramids?

Why I'm wondering - the reflective surface of electric heaters produced in USSR had a traingular surface shape and the bends was 112 degrees. Always.

Is there something valuable to learn from this or was it just a design feature? Does the 112 angle provide better overall reflection or..?

Sorry, EN isn't my 1st languague..

Radiant heaters try to focus the radiation, which is completely different from what a radiant barrier is doing. Flat is best for that.

Are there any research to support that or is it just common sense or something else?
