Product Overview 

The Q-V Thermal 90° Bend is a high-quality, fire-retardant ducting component designed to provide smooth directional airflow changes while maintaining thermal insulation and safety standards. Available in 125mm, 150mm, and 200mm internal diameters, this 90-degree bend is ideal for MVHR, industrial ventilation, and insulated ductwork systems.

It is manufactured from EPP (Expanded Polypropylene), a tough, resilient, and impact-resistant foam that can recover from multiple impacts. The material is impregnated with a flame retardant to GB8624 Class B1 and is currently under test to EN 13501-1 Class B, ensuring both durability and enhanced fire safety.

Crafted for demanding environments, each bend ensures secure fitment, efficient airflow, and long-lasting performance while meeting modern fire safety regulations.

Frequently Asked Questions

  • What is thermal ductwork used for?

    Thermal ductwork is used in ventilation systems where an insulated duct run is required. It can help reduce heat loss and lower the risk of condensation in suitable duct routes.

  • Where is thermal ductwork commonly installed?

    Thermal ductwork is commonly used in areas where ducting may pass through colder spaces, such as lofts, roof spaces, ceiling voids or unheated areas, depending on the ventilation design.

  • Does insulated ducting prevent condensation inside the duct?

    Correctly specified insulation can significantly reduce the risk of condensation by limiting temperature differences between the duct surface and surrounding air.

  • Is thermal ducting a building regulation requirement?

    Insulation requirements depend on the duct location, system and applicable Building Regulations. Ductwork passing through unheated spaces commonly requires suitable insulation.

  • Do I still need thermal ducting if the loft itself is well insulated?

    Potentially, yes. If the ductwork is outside the insulated building envelope or carries air at a significantly different temperature, additional duct insulation may still be required.
