Do the silver/aluminium fabrics allow air through or would you find that in the mornings you have condensation inside the inner tent like you do in the little two man single skin tents sometimes due to the small area.
My apologies. I was so knocked back that you had no knowledge of the silvered fabrics that I didn't read your piece properly or give it full consideration.
I was in a haberdashery emporium today (or are they all cloth houses now) who had sold a silvered fabric at one point. Alas they had no idea of technical specs and no longer carried it.
Do small tents have condensation problems because they are small or because they are almost invariably given nylon inner tents.
I have a four man tunnel tent from Vango (The replacement for the one holed on first visit to Dent) that does have condensation issues. Not big ones but condensation is discernible. I also have an older Blacks ridge tent circa 1985 still rip stop nylon but with a cotton inner tent. Never seen any evidence of condensation.
I don't know if the weave of cotton inner tents is looser and allows water vapour to escape while still being waterproof (a la Gore-Tex) So is it a tighter weave in the nylon that causes condensation or does the cotton just absorb a certain amount of moisture hence why your using it in PVC awnings?
Or perhaps both factors affect the outcome?
Would the cotton tent that the silvered fabric lined save me from condensation by wicking it up, or would the condensation still be on the surface of the PVC?
Whose to say, I need to have the thing made first. I need to find out about silvered fabrics.
