This is not greenhouse related but there will be plants down here. I'm sure there are some professionals here that can weigh in. I'm set on doing a skylight here on the right of this cover where it is currently open. The opening is apx 13'x8'. the rest of the sheeted roof will be steel.
I'm weighing my odds on if the 8mm twinwall will be worth it considering it's 1.7 r value. Vs doing a corrugated single wall polycarbonate panel that matches up perfectly to my steel (much easier to do than blending twinwall on top)
Zone 9. Northern California. We have dry hot summers. Will this make a noticeable difference going twinwall for heat transfer?
Any input is appreciated. Thank you.
