Slab Insulation
Slab insulation plays a critical role in the performance, durability, and energy efficiency of concrete structures. In under-slab and structural applications, insulation must withstand heavy loads, resist moisture, and maintain long-term thermal performance.
Reitzel Insulation provides professional slab insulation services using high-performance spray foam systems designed for demanding commercial and industrial environments.

Performance Characteristics
High-performance slab insulation systems are selected based on specific project demands. Key performance considerations include:
- Compressive strength to support structural loads
- Moisture resistance to prevent water intrusion
- Thermal stability for long-term energy performance
- Continuous coverage without seams or joints
Why Slab Insulation Matters
Concrete slabs are in direct contact with the ground and are subject to moisture, temperature variation, and structural loading. Without proper insulation, slabs can contribute to heat loss, condensation, and long-term material degradation.
Effective slab insulation helps:
- Reduce heat transfer through concrete
- Improve energy efficiency in conditioned spaces
- Protect slabs from moisture-related issues
- Support long-term structural performance
In commercial and industrial settings, insulation must perform reliably under sustained loads and environmental stress.
Slab Insulation for Demanding Applications
Slab insulation is commonly used in environments where traditional rigid insulation may not meet performance requirements. Spray foam slab insulation forms a continuous, monolithic layer that conforms to the substrate and eliminates joints or gaps.
Applications include:
- Under-slab construction
- Parking structures and decks
- Industrial floors
- Cold storage and specialty facilities
The seamless nature of spray foam insulation helps ensure consistent thermal and moisture control across the entire slab surface.
Commercial and Infrastructure Uses
Slab insulation is frequently specified for large-scale and infrastructure projects, including:
- Commercial and industrial buildings
- Parking decks and plaza structures
- Ice rinks and specialty floors
- Transportation and utility-related structures
Each application requires careful evaluation of load requirements, environmental exposure, and long-term performance expectations.
Choosing the Right Slab Insulation System
Different slab insulation systems are engineered for different load and usage conditions. Reitzel Insulation works with spray foam systems designed to meet varying compressive strength and performance requirements.

Slab Insulation FAQ
Slab insulation is used beneath or within concrete slabs to reduce heat loss, control moisture, and support long-term structural performance.
Slab insulation is most common in commercial and industrial settings, but it may also be used in specialized residential applications.
Slab insulation must support the weight of concrete and applied loads without deformation, making compressive strength a critical factor.
Yes. Proper slab insulation helps limit moisture movement from the ground into the structure.
