He wonders why Structural Insulated Panels (SIPs) don’t get more attention

Hi, and thanks for the info on Net Zero homes by the year 2030. I have do have a question I’d love to hear everyone’s insight on. I’ve been doing some research recently on all of this, and it seems to me in all of these efforts (as you’ve pointed out regarding the issues using solar, the cost of building these homes, etc)., one major contributor to far more energy-efficient homes that does not cost any more, and that is NOT being talked about, is the use of Structural Insulated Panels.

In all of these talks about building green homes, everything seems to be focused on expensive new tech like solar, better HVAC systems, etc. While all that stuff is good, you’re right, it’s expensive. But why is one method that is very efficient, and not expensive to use, not being talked about more? From my research, it seems like half the battle can be won (plenty of studies showing a minimum of 50 per cent improvement compared to traditional framing methods) starting with this one approach alone. Would love to hear contractors and others weigh in on this. Thanks!
