Under-Slab & Radiant-Heated Floor Spray Foam

We install high-performance *closed-cell spray foam* beneath concrete slabs and under radiant-heated floors to boost efficiency, comfort, and durability. Closed-cell foam delivers excellent R-value in a thin profile, helps control moisture, and provides compressive strength suitable for slab support.

Why It's a Great Fit:

• Higher efficiency: Reduces heat loss to the ground for faster warm-up and lower energy use.
• Comfort you feel: Keeps floor temps more consistent across the room.
• Moisture control: Acts as a vapor retarder to help limit ground moisture migration.
• Protects radiant systems: Encapsulates and supports hydronic tubing before the pour.
• Thin, strong, durable: Structural compressive strength options to meet project needs.

Typical applications:

• New builds and additions
• Garages, basements, shops, and slabs-on-grade
• Hydronic radiant heat systems
