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.
