Inspecting Spray Foam Insulation Installation in an Old Bungalow Style House (What to Look For)

Older homes that were built in the early 1900's were not insulated originally and this video shows an insulation inspection done during a big renovation on a 1927 bungalow style house that had open-cell spray foam installed on the underside of the roof deck and behind most of the second floor walls.

The homeowner's goal here was to make the house as reasonably comfortable as possible, within her budget, and to plan for future upgrades in a cost effective manner.

We discuss why she chose spray-foam for this house and show what areas still needed some work, along with addressing bath ventilation issues and the current state of her HVAC system and ductwork and what improvements to consider to them.

What You'll Learn:

✔️ Why spray foam insulation is not a "silver bullet" and should always be inspected before drywall is hung over it.
✔️ Specific areas of the house where problems with spray foam insulation can occur
How framing issues can prevent a house from being properly insulated and options to fix them.
✔️ Best ways to run exhaust vents out of attics.
✔️ How to insulate foundation walls properly in an older home
✔️ Improvements you can make to ductwork and air filters to improve HVAC performance and indoor air quality
