Thermal 200mm to 150mm reducer (Fire Retardant)

SKU : QV-TH-200-150-R

Overview

The Q-V Thermal 200–150mm Pipe Reducer is a robust, fire-retardant fitting that securely connects a 200mm Q-V Thermal pipe to a 150mm Q-V Thermal pipe. It is manufactured from EPP (Expanded Polypropylene), a tough, resilient, and impact-resistant foam that recovers 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. This ensures both safety and long-lasting performance while maintaining thermal insulation and airflow efficiency.

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.
