In a mixed climate area in Northern California (Lake County) where the summer temps can often reach over 100 and the winter temps fall below 32 at times, can I effectively reach the required R-30 insulation requirements with a metal roof over rigid insulation and an open rafter interior situation?

We're remodeling a garage into a studio and want to "seal" (while allowing breathing) the exterior walls and then insulate. The siding is in pretty good shape (a few cracks) and is nailed directly to the studs. What is best for sealing the cracks? And can we insulate without building paper? Is there a way to install a wrap of some sort without removing the siding?
Thanks.

I live in Baltimore. I have been thinking about maintaining high solar heat gain in my windows for winter benefit. In the summer, when I need to put up insect screening anyway, my thought is to use one of those dual purpose insect screen and solar screen (e.g. like Linay type). I don't see any measured SHGC on the solar screen websites but there are apparently 70-90% solar radiant heat reduction options. I like the idea of cutting down the radiant heat before it reaches the window pane to reduce cooling load.

Thanks for your advice!

Came across an article on the cost of asphalt going forward that should be food for thought for builders interested in ensuring that homeowners can afford to stay in their homes in the long run. Since asphalt shingles are the predominant roofing choice I thought the following article might make people reconsider roof design going forward. Essentially asphalt is going to get more expensive , so shingles will cost more!

Hi, I am in the middle of building a home. The contractor has placed one-inch rigid foam insulation of the exterior of the home. Vinyl siding is going over this. At the bottom of the house, where the siding stops, you can reach under and feel the foam insulation. It is about 2 feet above grade.

Do I need to seal the bottom of the foam to prevent any critters from getting in, and if so how?

Here's a something I've had a hard time getting good advice on. Hopefully someone can help:

I'll soon be digging a pond that will rely on a dam built of clay excavated from the from the deep end of the pond.
I've read that clay should be compacted at “optimum moisture content” - whatever that is. At this time of year the excavated clay will be quite dry.
What is the “optimum moisture content” for compacting clay?
If the clay is compacted dry, will the level of compaction be very far off from where it would be if it were compacted at “optimum moisture content”?
