I am hoping you guys can chime in, I figured this was the most appropriate forum to post this in. If not, please move, and so sorry!
I am wondering if a sort of diy vacuum insulated panel would be feasible to produce. The main issues I can think of are that the vacuum will eventually fail, or that the way in which the panels are normally designed are incompatible with a DIY approach.
If a simple design could be thought up, and one that would hold insulation indefinitely, assuming all the best, that would really change how one could build in any climate, and give some power back to those who are looking to build there own homes.
I know it is likely a pipedream, but if anyone could offer advice or thoughts, I'd truly appreciate it!
If using glass I think it could be done but you would need bracing in between the panels to support them and keep them from bowing in due to the vacuum. I would think it would need to be some sort of square tubing with holes from side to side to allow the air to pass through while vacuuming out the air. The only vacuum pump I am familiar with (just because I don't know of others due to lack of experience) is the one for working on AC systems. With that in mind I think you would need to have the valve fitting built into the window frame so you can attach the vacuum pump hose, but you would need to have a very accurate gauge so you know when to stop before the glass shatters. (if'n the glass would shatter)
Any my final thought is glass itself is not a good insulator for heat/cold. Properly designed it would be better than just a glass panel but I don't think it would have a very good R-value.
This is definitely a good topic for discussion. Plenty of knowledge and creative minds on this forum.
I think this way is probably not within diy reach, in a practical manner at least.
I was hoping some sort of shell, say plastic, with a core of insulatable material could be vacuum sealed, and perhaps not be as good as the "proper" types, but could hopefully be easily diy and also greatly increase an R value of insulation.
