How do I remove aluminum siding to insulate my home?
First- consider the risks of damage, and find out if you have or can get spare material. Aluminum siding is easy to bend or damage, and very hard to straighten out. You can’t “spring it out” and have it snap back like vinyl siding. The siding is installed starting at the bottom. Each piece locks into a rolled groove at the top of the piece below it, and nails at the top. The nails are covered by the next piece. Removal therefore starts at the top. There will be some kind of trim that covers the final edge, Remove the trim, then remove the nails and the top piece. Doing the under windows may be less desirable, and presents the highest risk. Consider leaving them un-insulated, or injecting insulation from the inside through sheetrock. If you choose to do it outside, you may have to remove most of the wall to get to it.
