Hey there!

I read some interesting stuffs about Vaccuum Isolation Panel (VIP). It seems to be an amazing technology to make substantial energy savings . However, I'm not too sure about if it's relevant to use them: they seem very, very fragile and expensive.
Has anyone tried it yet? What would be your feedback about their performance vs cost?

Thank you very much.

Cheers!

3.5x R value is interesting. It seems to me that a steel SIP with sealed edges and a hose connection to pull/re-pull a vacuum now and then is pretty close to one of those.

Are you talking glass or wall panels? I am buying some triple glazed VIG for some replacement fixed skylights which I hope will stand the test of time.

Thanks to MikeSolar and jonr!

Jonr, I haven't seen any SIP connected with a hose to a vacuum system. That could be a good solution indeed. Do you have any links? Have you tried them yet? However I tought that vacuum insulated panels and structural insulated panels were different. And that structural insulated panels were not working with a vacuum technology.

MikeSolar, I'm talking about panels that would be installed in a wall. Here is a link of what I'm talking about: http://www.toolbase.org/Technology-Inventory/Interior-Partitions-Ceilings/vacuum-insulation-panel.

Thank you!

I haven't seen anything like it, just noting that a steel SIP is not too far from a possible VIP design that would address durability and vacuum loss issues.

Sounds like perlite is a reasonable fill material. Steel vips might be great for window shutters and outside doors.

But would it be suitable to use them within a wall (rather than just for window shutters and outside doors)? It seems that in practice, many different materials are used to insulate a house. I'm wondering if it's a budget issue or if there are any upside in using different materials for different part of the house.
I mean if VIP or SIP are impressive, why not use them all over the place?

Thanks

In theory, all kinds of things might be experimented with.

In practical use, everything is subject to a cost/benefit analysis.
