Kingspan Kooltherm® FM Duct Insulation is an energy efficient rigid insulation for rectangular, circular and flat oval HVAC ductwork, suitable for both new build and refurbishment projects in the residential, commercial, institutional and industrial sectors.

Comprised of a fibre-free rigid phenolic insulation core, faced on one side (external face) with an aluminium vapour barrier foil, and faced on the other side (internal face) with a glass tissue based facing.

Insulated duct support inserts:

Load-bearing insulation inserts can be fabricated from standard Kingspan Kooltherm® FM Duct Insulation boards.

Flat rectangular strips of Kingspan Kooltherm® FM Duct Insulation are used on support brackets with rectangular and flat oval ductwork. Curved strips of Kingspan Kooltherm® FM Duct Insulation (crocodile strips) or strips of Kingspan Kooltherm® FM Pipe Insulation are used on support brackets with circular ductwork.

FM approval:

FM approved to Factory Mutual (FM) Research Standard 4924 when manufactured and installed in accordance with the conditions defined by the approval. It is a low fire hazard product acceptable in itself, without requiring automatic sprinkler protection.

Standard product features

Facings:

Kingspan Kooltherm® FM Duct Insulation comprises a rigid thermoset phenolic insulation core faced on one side (external face) with an extremely durable and protective low vapour permeability 25 micron aluminium foil reinforced with a 5 mm glass scrim, and faced on the other, internal, side with a glass tissue that is compatible with the types of solvent–based general purpose adhesives commonly used for adhering insulation materials to ductwork. Both facings are autohesively bonded to the insulation core during manufacture.

Thermal conductivity:

0.022 W/m·K at 10°C mean and 19°C mean.

Thermal performance:

Satisfies the requirements of the Non-Domestic and of the Domestic Building Services Compliance Guides, BS 5422: 2009 and the TIMSA Guide.

Fire and smoke performance:

  • FM approved.
  • EN ISO 5659-2: 2006: specific optical density of smoke – 0 (zero) at 25 kW/m2 and 6 at 50 kW/m2 with pilot flame.
  • The aluminium foil facing is rated Class O to the Building Regulations.
  • ASTM E84 / UL 723: surface spread of flame index less than 25 and smoke developed index less than 50.

Compressive strength (minimum):

100 kPa at 10% compression.

Closed cell content:

≥90%.

Nominal density range:

30–35 kg/m³.

Water vapour permeance of the outer facing:

0.02 perm (grains/h ft2 inHg) = 1.15 ng/ N s (ng / s m2 Pa).

Operating temperature limits:

-20 to +80°C.
