Retrofoam House Insulation

[jyl]

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.

Seems legit, I would definitely get references and make some phone calls and perhaps some visits to the referenced homes.

The foam bonds to everything it touches.
Including wires and pipes.

The foam pushes into every opening it can find.
Such as switch boxes.

All future remodeling will be a pain in the ass.



"Non expanding" ??
Their video shows that it expands to fill the cavities.
It even shows the foam intruding into a light switch box.

1-2 inch hole.....That hole was 4 inches in the video. And that siding almost came off on its own.
