How do I dec I'd love spray foam, but I doide what insulation is best?
I'm starting to refurbish a ca. 1947 home. Weather-worn aluminum siding over the original wood clapboards. I want to strip the existing siding, replace the insulation, wrap, and re-side with HardiPlank. Which is the best way to insulate? Because of tight money (new divorcee), I'll be doing only one side of the house at a time.

Are you stripping the sheathing down to the studs? If you are opening up the studs, fiberglass batts are easier to put in, are less expensive, have a higher R value, and you will have less waste. Spray foam is excellent at air sealing, but is the most expensive way to insulate. Living in a warmer part of the country, you probably don't need two layers as some people in colder regions would use batts in the walls and sheathe with rigid foam. Blown in cellulose has a slightly better R value than fiberglass, but is more trouble to install and costlier. Rigid foam in the stud bays is harder and costlier if you are doing it yourself as well. If you are keeping the existing sheathing in place and your stud bays are already insulated, then you could add a layer of rigid foam over the sheathing to increase your overall R value. This may change the depth of your window casings and you may need to add jamb extensions. Being a 1947 house, your stud bays may not be insulated, in which case blown in cellulose may be the way to go. You will also want to consider adding a rain screen under your siding. Are the wood clapboards in bad shape? You may want to consider keeping them and blowing in insulation.
Spray foam usually is the best idea but it can get pricey. The newer white insulation is extremely thick so you can split its depth in half and do twice as much. It's way cheaper and won't cause you to itch and is allergy rated good. I used it when I redid the outside of my house and even noticed the muted sound of the interstate which connects to my property. Hope this helps and good luck.
Hi Alex. Too much insulation can be a bad thing. Houses need to breathe especially in the Gulf Coast states.

I think Tyvek wrap would be the best way to go for your project. It is easy to install, and it does a good job. It comes in a wide roll that you roll out and nail to the house using a product called ‘plastic cap nails’ (see pic). This is a two-person job though; one person unrolling the Tyvek, another nailing it to the house. One other thing I should mention; Tyvek is a brand name. You might find it called by another name.
