I'm putting 7/16 osb sheeting vs 1/2 foam board due to twice the cost of product .this is going?

I'm not sure how much renovation has been done to the house but I would be cautious and remember to wear respiratory protection because a lot of houses built prior to 1972-1974 in the US have asbestos-containing building materials throughout.

The biggest con is that you will have a lot of work to do with extending the window and door trim. It will also trap all of the moisture that is currently in the wood siding, not allowing it to properly breath. I would seriousely consider removing the redwood siding that you are planning on going over with the 7/16" sheeting for a few reasons.

The first is that this will expose the original sheething of the home, which is probably dimensional lumber installed at an angle or horizontally. At this point, you may not need to put any kind of sheeting over the walls. Just make sure that you properly install 15 lb asphalt based felt paper or a high quality house wrap over the original sheething.

I personally prefer felt paper, but you can use house wrap if you want. There may be some areas where the sheething is rotted that you may need to replace it, but it is probably in better condition than you think. You can then install your siding normally without extending window and door trim and you can flash everything properly without having to purchase or make custom flashings.

I hope this helps. Good luck with your project.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
