I've been reading up on that subject. As long as it's a miltilayer product, it will insulate. Some of the multilayer insulation blankets used in the space program have only hundredths of an inch between layers, and yet they are effective. it doesn't take much space, but I get the business of it not working if there's no space. Infra red has to have room to travel, otherwise it's nothing but conduction.
I'm sorry to find out that my manifold is of low quality. In the past, I've built them from scratch, and I had high hopes this would do it all in one simple package. Oh, well. I'll make do.
Here's the small result from today's work as we got rained out by noon. mm
