Underslab Insulation

At Polar Bear Spray Foam Inc., we specialize in providing high-performance underslab insulation using premium closed-cell spray foam. This advanced insulation method offers unmatched energy efficiency, moisture protection, and structural support for residential, commercial, and industrial projects.

Under-slab insulation involves applying closed-cell spray foam beneath concrete slabs before the pour. This creates a seamless, airtight, and water-resistant thermal barrier that helps regulate temperature, reduce energy costs, and prevent issues such as frost heave and ground moisture intrusion.

Unlike rigid foam board or other traditional materials, spray foam conforms perfectly to every contour of the ground, eliminating air gaps and thermal bridging. The key benefits include:

• Superior Thermal Performance: Closed-cell spray foam boasts one of the highest R-values per inch, keeping your floors warmer in the winter and cooler in the summer.

• Moisture Resistance: Acts as an effective vapor barrier, protecting the structure from dampness and preventing mold or mildew development.

• Enhanced Structural Integrity: Adds compressive strength beneath the slab, helping distribute loads more effectively.

• Long-Term Savings: Reduced energy bills and lower HVAC strain, leading to long-term cost savings.

• Quick & Efficient Application: Our experienced team ensures fast turnaround times while maintaining the highest quality standards.

• New home construction

• Garages and workshops

• Warehouses and commercial buildings

• Basements and crawlspaces
