Spray foam insulation went in this week. It is amazing stuff! It is sprayed in and allowed to foam to the fullest. Then the excess is scraped off leaving a flat surface so drywall can be installed. This is hi-tech super efficient insulation, the best you can get.
Thoroughly foamed in every little nook and cranny.
Foam was applied under the roof behind kneewall.
Thick foam will insulate the new bedroom.
Special orange foam seals cracks and stops fire from spreading.
Even the smallest spaces are treated with foam to fill gaps.
The roof is the ceiling in this room, now thoroughly insulated.
Foam does not have to be trimmed if it is not in the way.
It almost looks good enough to eat.

Mr. Pixel
Thanks for posting these photos. I can see how the foam would be very efficient. Is there any downside compared to other types of insulation? What if plumbing or electrical need to be worked on in the future? Or is that even worth worrying about?

Good question. The foam is not rigid when dry. Pipes or electrical could be accessed by pulling or gently tearing away the foam. The foam can be replaced after the work has been completed. There are small canisters of spray insulation designed for patching. I think the cost would be prohibitively expensive to do a big job, but perfect for touchups.
I’ve taken many photos of the walls so I”ll have a record of precise posiitioning of pipes, electrical and duct locations before drywall is installed. Hopefully this will come in handy if repairs are needed in future.
P.S. I know of no downside to this type of insulation but I’ll check with Mr. Barnum.

Reddi-wip is on sale this week at the Piggly Wiggly in Danville. Two cans for $2.49. It’s a 200 mile drive but might be worth it – tastes as good as it looks.

The biggest downside is the up-front cost of spray foam insulation. It could cost $20K for a small house. Definitely a long-term investment. Energy costs are unlikely to go down, so energy savings may increase over time.
