Designing an insulated tent

Hello,

I am an avid camper and am in the process of designing an insulated tent, to go on the market this summer.

The design includes a 25mm thick insulated inner tent wall (compresses to half that), nylon ripstop, alu poles, vis a vie with vestibule, light green, 5-6 berth.

Main benefits are:

Heat retention
Heat exclusion in very warm climates
Very good acoustic performance

It won't be light but will some of the extra weight will be offset with other materials such as the alu poles.

I guess my questions are:

Will it have appeal?
What else should be considered in the design?
Would it work at 450 euro price point?

Thanks,
Derek.
