Question about insulating an old house.

My house was built in 1911. Wood frame. Not insulated. Wainscoting and built-ins cover most of the downstairs walls.

I'm interested in this injected foam process. Spray Foam Insulation | RetroFoamâ„¢ - Foam Insulation for Existing Homes

They claim
- Non flammable
- Mold resistant
- No off gassing
- Non expanding
- Sound and temperature insulation
- 4" is R15, 6" is R27

What do you think? See the video.
