Block the Heat. Boost Performance.
When HVAC cabinets are exposed to direct sunlight, exterior temperatures can reach up to 180°F—even on mild days. As a result, this solar heat load drives up interior cabinet temperatures, making your HVAC unit work harder than it should.
The result? Increased run times, accelerated wear, more frequent repairs, and a shorter system lifespan.
How ThermalBlock™ Works
This is a is a high-performance radiant barrier coating designed to shield rooftop HVAC systems, exposed ductwork, and metal cabinets from solar heat. Applied directly to exterior surfaces, it reflects solar radiation before it can increase cabinet temperatures.
Once applied, ThermalBlock™ blocks up to 93% of solar heat, instantly reducing surface temperatures to within 10°F of the surrounding air—even in peak summer conditions.
Designed for Real-World Conditions
While HVAC units are tested in ARI-certified labs, they’re rarely evaluated under real rooftop heat-load conditions. In practice, most rooftop units operate under extreme solar exposure, which lab testing doesn’t reflect.
ThermalBlock™ bridges that gap—delivering performance in the environments your equipment actually faces.
Real Impact on Energy Use & Equipment Life
By keeping your cabinet cooler, our coating:
- Reduces HVAC run time, especially during high-demand periods
- Lowers energy consumption (kWh)
- Extends unit lifespan
- Reduces repairs and long-term maintenance costs
And since it can be applied on-site, it’s a smart, low-disruption upgrade for both new and existing systems.
Proven Results & Fast ROI
Extensive independent lab testing confirms the effectiveness of our coating. In real-world applications, customers often see:
- ROI in as little as 12-36 months
- ROI in as little as 12-36 months
- A longer-lasting HVAC system
