hello! my greenhouse is done, (we do have a door) but I'm wondering how to fill the larger gaps, specifically where the joists and roof meet the sidewall.
would it be best to put a piece of plywood up and run it all the way out towards the edge? or should I cut separate pieces to fit between the joists? the building is wonky as shit so they would need to be individually measured, but if that's what it's going to take, I'm of course willing to do it.
My goal is to keep the greenhouse well heated even through my zone 5 winter by using dark colors on wood and rocks, water barrels, and a large hot bed compost area directly on the other side. But having these large gaps at the top for all of the heat to escape is working counterwise.
I'm quite new at this and wondering if there is a preferred method for this specific gap.
Thanks in advance!

Use something like 2 inch foam board insulation to make a plug that you can pull out in the summer to let heat out
Love the color
My greenhouse has similar gaps and I just used pool noodles to close the gaps for winter.
Impressive build!
For temporary blockage the 2 inch foam board insulation works well. For permanent, I’d take a piece of corrugated shaped wood pieces available at your favorite big box store, and attach those to a 2×4.
As foam decomposes in the UV light over the years, I use empty kitchen rolls. They are completely biodegradable after the winter season.
