Eliminate condensation, maximize efficiency, and ensure seamless integration with all heat pump and HRV units. TQ-Air® delivers professional-grade ducting solutions for superior system performance.
SMART DUCTING SOLUTIONS
Pre-Insulated Ducting System
Ventilation systems face costly risks: condensation, energy losses, and complicated installations. TQ-Air® pre-insulated ducting system eliminates condensation, accelerates installation, and guarantees airtight, reliable performance with heat pump or HRV system.
PROVEN INDUSTRY PARTNERSHIPS
Trusted by Heat Pump Manufacturers
With decades of experience developing TQ-Air pre-insulated ducting systems for heat recovery and HVAC applications, Thermaflex partners with leading heat pump manufacturers worldwide. Our vapor-tight polyolefin insulation technology prevents condensation, reduces noise by up to 20 dB(A), and ensures energy-efficient air distribution. From compact residential heat pumps to large-scale commercial installations, our flexible ducting networks minimize heat loss, integrate seamlessly with all ventilation units, and deliver the reliability your customers demand.
CONDENSATION-FREE VENTILATION
Engineered for Heat Pump Integration
TQ-Air pre-insulated ducting systems are specifically optimized for heat pump ventilation applications, addressing the critical challenge of condensation in HRV and HVAC systems. Our closed-cell polyolefin foam insulation with vapor-tight structure prevents moisture buildup, while the shock-resistant PE outer casing withstands installation demands. Available in multiple diameters (125mm, 150/160/180mm, 200mm systems), our prefabricated components—including flexible seals, T-pieces, and reducers—eliminate installation errors, accelerate project completion, and ensure completely airtight systems. Cradle-to-Cradle® Silver certified for sustainability and fully recyclable for end-of-life value.
EXPERT PROJECT GUIDANCE
Complete Support for Your Projects
Our ducting solutions adapt to every heat pump installation challenge, from single-family residential systems to multi-unit commercial projects. Prefabricated components reduce installation time by 30-40%, minimize on-site labor costs, and ensure optimal performance when paired with your heat pump and HRV equipment.
