Most people still think spray foam is “just insulation.”
It’s not.

This in-ground pool project is sitting on CLOSED-CELL SPRAY FOAM — perimeter and floor.

Why?

Because properly installed closed-cell spray foam is:
✔ High compressive strength
✔ Water resistant
✔ Seamless
✔ Bonded in place
✔ Able to handle serious load forces

This isn’t fluffy insulation trapping air in a wall cavity. This is engineered plastic foam with real structural and performance characteristics.

The conversation around spray foam is changing fast.
Builders, engineers, and homeowners are starting to realize this material can do far more than simply hit an R-value target.

Under slabs.
Pool floors.
Perimeters.
Cold storage.
Commercial envelopes.
Condensation control.
Air sealing.
Moisture management.

Modern building science is moving forward.

In this featurette video we break down:
🔹 Why spray foam was chosen
🔹 How much crush force it can handle
🔹 Why seamless insulation matters
🔹 What makes closed-cell different from traditional materials
🔹 The technical side most people never hear about

Can spray foam really hold up under a swimming pool?
