So this is a question for an HVAC technician or anyone else familiar with vacuums and how they work. In the construction industry they use vacuum insulated panels that have a high R-value (40-60 depending). What If I applied this to clothing, that is to say can a vacuumed sealed chamber be flexible? I understand that the sides of the seal cannot touch each other because that would defeat the purpose of it.
My idea was to use thin vacuum tubing weaved together in areas of the fiber such as the arm pits, core and other key areas. If a small gauge, release valve and hand hand pump were embedded into the jacket, you could essentially control home much your jacket insulates. Another idea I had was to take hollowed out plastic membranes and use them like wool or cotton batting. Weaved with other types of material such as Kevlar and heat resistant foils and you could withstand extreme environments for a long period of time, on body heat alone.
