Yes, they do make demolition blades. Available at Home Depot.

If you have a team (two guys changing blades on saws, and one on the saw
that's being used) you can use blades from Harbor Freight. But, they don't
last very long.

Good ideas, but this is a demolition job of the old part of the house.
The newer part was already cut away and walled off. No plumbing in
there since it was removed first. If I cut wires that dont matter, the
power is off and all the wire is being very old K&T or cloth covered
romex which will be sold for scrap. While removal of plaster would
help, because of fallen parts of the roof and other things that
collapsed, it's too dangerous to go inside. The walls are being cut
into sections from the outside and dragged with machinery to a burn
pile.
