Choosing the right industrial insulation material is crucial when constructing or upgrading large facilities. These environments demand durable, high-performance solutions that contribute to long-term energy efficiency and structural resilience. One insulation material stands out for meeting these demands: closed-cell spray foam.
But what exactly makes it a superior option for industrial applications? Let’s explore the characteristics and benefits of closed-cell spray foam and why it continues to gain traction across commercial and industrial sectors.
What Is Closed-Cell Spray Foam?
Closed-cell spray foam is a dense, rigid polyurethane insulation applied on-site by trained technicians. The foam expands and hardens as it cures, forming a seamless and airtight layer that tightly adheres to a variety of substrates, including metal, concrete, wood, and masonry.
Unlike open-cell spray foam, closed-cell foam features completely enclosed cells. This structural difference gives it superior rigidity, high insulation value, and enhanced resistance to outside air intrusion, critical features for industrial settings where performance cannot be compromised.
Top Benefits Of Closed-Cell Spray Foam For Industrial Facilities
1. High R-Value Performance
Closed-cell spray foam boasts an R-value of around 6.5 per inch, offering one of the highest thermal insulation ratings per inch among insulation types.
This means better energy efficiency using less material, a huge advantage in industrial buildings where wall or ceiling space might be limited.
2. Airtight Sealing Power
Industrial operations often require controlled environments for machinery, materials, or workers. Closed-cell spray foam expands to fill all cracks, seams, and penetrations, providing an effective air barrier that helps maintain stable internal temperatures and reduces stress on HVAC systems.
3. Reinforces Structural Integrity
Because of its rigid nature, closed-cell spray foam enhances the strength of wall and roof assemblies. It improves shear and racking strength when properly applied between studs, helping industrial buildings better withstand shifting loads and dynamic environments.
4. Supports Code Compliance With Proper Coatings
Closed-cell foam can be installed in compliance with Canadian building codes when paired with fire-resistant coatings such as DC315, but only over foam types that are approved for it. This makes it a safe option for wall cavities, ceilings, and attics in large facilities requiring thermal protection with added fire safety precautions.
Note: DC315 should not be used over ½-pound spray foam. It is approved only over specific closed-cell systems.
Perfect For Harsh Industrial Conditions
Designed For Thermal Control
Industrial spaces in Alberta face wide-ranging temperatures, from freezing winters to hot summers. Closed-cell spray foam creates a thermal barrier that protects building interiors from the impact of external climate conditions, helping maintain efficiency and comfort.
Adheres To Almost Any Surface
Closed-cell spray foam can be applied to steel framing, concrete walls, tilt-up panels, or wood structures, offering flexibility in industrial construction. Its ability to bond tightly to substrates ensures a long-lasting solution in both new builds and open-structure retrofits.
Reduces Airborne Noise Transmission
While not designed as a soundproofing material, the dense nature of closed-cell spray foam helps dampen external noise by reducing air gaps in wall and ceiling cavities.
This can lead to quieter, more productive working environments in noisy factory settings or mechanical rooms.
Common Industrial Use Cases
Closed-cell spray foam is well-suited to a variety of industrial facilities and systems, including:
- Warehouses and logistics centres
- Cold chain storage (with proper HVAC integration)
- Mechanical and utility rooms
- Agricultural buildings and barns
- Steel-framed factories
- Tilt-up concrete manufacturing units
- Commercial rooftops and envelope retrofits
Each of these settings benefits from the foam’s high R-value, strength, and air-sealing properties, contributing to efficient operations and long-term cost savings.
Sustainability And Long-Term ROI
Because it forms an airtight seal and has a high thermal resistance, closed-cell spray foam reduces energy demand. This can translate to significant long-term cost savings on heating and cooling systems.
Many industrial clients see payback periods of just a few years based on improved energy efficiency alone.
The material’s durability also minimizes the need for replacement or reapplication, making it a wise long-term investment in both performance and sustainability.
