Thermaround - Extreme Outdoor Resistance for outdoor spiral ductwork
For outdoor ductwork systems, Thermaduct’s Thermaround offers unmatched durability and weather resistance. Engineered with a 1000-micron UV-stable vinyl cladding, Thermaround ensures long-lasting performance with minimal seams and joints, resulting in lower air leakage and fewer maintenance requirements. With a patented construction and solvent-welded seams, Thermaround creates a continuous, sealed surface that effectively withstands harsh environmental conditions. It’s designed for commercial HVAC applications that demand maximum thermal protection and reliability.
Installing contractors will feel right at home with our outdoor duct systems, whether new construction or retrofit applications. Quickly connect to existing spiral or rectangular ductwork utilizing the standardized flanged connections and barrel connectors, easy and familiar to anyone who uses flanged spiral ductwork. We even offer brief online installer training to ensure your project gets off on the right foot!
Advantages of Thermaround for Outdoor Duct Applications
Superior Weather Resistance
Engineered to handle extreme outdoor conditions.
UV-Stable Vinyl Cladding
Prevents damage from prolonged sun exposure.
Low Leakage, High Efficiency
Improved insulation values, low leakage connections.
Virtually Seamless Design
Continuous cladding with minimal solvent-welded seams
Pharmaceutical Facility
Thermaround played a role in helping a Massachusetts pharmaceutical facility meet it's decarbonization goals and increase the efficiency of their building.
Downtown Boston Hotel
Located near the waterfront of Boston Harbor, this facility had a large portion of their HVAC system designed outdoors, exposed to the elements.
Montana Multiphase Hospital
Thermaduct products were the duct solution of choice for both phases of this hospital's R-12 pre-insulated HVAC system upgrades.
InspiralR - Lightweight, Pre-Insulated Spiral Duct Alternative for Interior Applications
Lightweight and easy to install, our round InspiralR system can drastically reduce the weight of installed spiral by up to 75%. This not only simplifies installation but also enhances structural safety by reducing the load on supporting systems. InspiralR features a smooth aluminum interior for optimal airflow without loose fibers entering the air stream, as can occur in fiberglass lined spiral or double wall systems.
For exposed applications, InspiralR can easily be painted to match specific design aesthetics. This makes it an excellent choice for exposed applications where both performance and appearance are crucial. InspiralR offer a clean, even look without the need for additional insulation wrapping that can often give traditional insulated duct an uneven or lumpy exterior.
Why Choose InspiralR
Lightweight Construction
Easier to handle and install, reducing labor time.
No Additional Insulation Required
Pre-insulated phenolic panels provide a 2-in-1 duct system.
Paintable Aluminum Exterior
Customize the appearance for exposed ductwork.
Reduced Energy Costs
Lower thermal loss means long-term utility savings.
Exposed Office Application
In late 2023 and into 2024, a four story office application utilized our InspiralR and Floval pre-insulated duct systems for their exposed ductwork needs.
Missouri Industrial Facility
To meet the weight restrictions on their metal building, this industrial facility turned to lightweight phenolic ductwork to reduce building loads.
School Lobby Renovation
With the exposed nature of the system, the paintable InspiralR aluminum exterior was utilized to closely blend into the school's new open cafeteria.
Thermaround Architectural - Designed for Aesthetics, Engineered to Perform
In applications where HVAC systems serve as architectural elements, Thermaduct’s Thermaround Architectural system delivers both performance and visual appeal. Utilizing two layers of pre-insulated InspiralR, encased in either a Kynar-coated or galvanized metal exterior, Thermaround Architectural is engineered for durability and aesthetics.
Designed for both indoor and outdoor conditions and code requirements, the system comes with 22 color options or a paint grip galvanized finish, allowing you to match your ductwork with any building design.
Utilizing the same flanged connections as our vinyl cladded Thermaround, installers will find our Architectural system to be fast and familiar to install on either interior or exterior applications.
How Thermaround Architectural is an Aesthetic Solution for Exposed Duct Systems
Architectural Design Meets Functionality
Aesthetically pleasing with high thermal efficiency.
Minimizes Water Intrusion
Single seam design where possible to reduce potential entry points for moisture.
Color Customization
Choose from a wide range of finishes to complement your building’s design.
Quick Installation
Standardized flanged connections ensure a fast, efficient installation process.
Hospital Application
One hospital in Akron, Ohio had a unique installation that required round ductwork to be installed in a location that required the HVAC system to blend into its surroundings.
School System Rooftop
In early 2022, this Minnesota school’s equipment replacement gave the opportunity to not only upgrade their system’s performance, but aesthetics as well with Thermaround Architectural.
