I have a 1950's cement block wall house I am remodeling. Someday I would like to replace the windows and maybe install vinyl siding with a foam insulation since there is none in the home. I'm wondering if you can fir it out, install foam insulation between and cover with siding. Is it okay to nail into the block without causing damage? I know they did the interior this way. Has anyone done something like this before, and if so, what is the proper way to do it? thanks!
