Duct Insulation

  • 25mm pre-insulated ducting reduced

    It is a mandatory requirement for NHBC Guidance Document Chapter 3.2 compliance that a Thermal Resistance of the insulating materials should be equivalent to a minimum of 25mm, with a thermal conductivity of 0.04 W/mK which gives a minimum Thermal Resistance requirement of 0.625 m²K/W.

    Insulation must be fitted to all exposed ductwork in order to prevent condensation from forming when ducting is located within cold void areas. Please be aware, however, that if you are looking to achieve a Passive House standard or considering the ComfoCool uplift on a Q600 it will be necessary to insulate all duct runs, irrespective of location.

  • Elbow Bends ROUND reduced

    Self-Seal Thermal Ducting

    * At 20mm thick, it provides a thermal conductivity of 0.03W/mK and Thermal Resistance (R-value) of .666m²K/W
    * Manufactured from Neopor® graphite impregnated polystyrene (EPS) with infrared absorbers and reflectors which improves the thermal resistance of the materials
    * Fully tested to meet the thermal conductivity requirement of BASF-EN13163
    * Flame retardant to DIN 4012 B1
    * Exceeds current UK DomesticVentilation Regulations for thermal properties
    * Independently airflow performance tested by the Building Research Establishment
    * Push, click and lock mechanism minimises air leakage and makes it easier to install

  • Isover duct wrap

    Foil Faced Mineral Wool Wrap

    * Required for ducting passing within cold voids
    * Improves thermal performance and reduces duct noise ingress/egress
