Kingspan Kooltherm Duct Insulation comprises a fibrefree rigid thermoset 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. Both facings are autohesively bonded to the insulation core during manufacture.

Kingspan Kooltherm Duct Insulation has a 90% (or greater) closed cell structure and a compressive strength that typically exceeds 100 kPa at 10% compression. Solutions are available to accommodate the surface curvature of circular and flat oval ductwork with an outside diameter (O.D.) of 80 mm or greater.
Thermal Conductivity 0.022 W/mK (at 10°C, time averaged value over 25 years)
Euroclass C
Facings 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
Core Premium performance rigid thermoset phenolic insulation core manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP)
Board Size 1.2 x 0.6 metres
Weight Approx. 2.0 kg/m2 at a thickness of 50 mm
FM Approval Factory Mutual Research Approval Standard - Pipe Insulation Class Number 4924 when manufactured and installed in accordance with the conditions defined by the approval.
Insulated Duct Support Inserts 1
Load-bearing insulation inserts can be fabricated on site from standard Kingspan Kooltherm Duct Insulation boards to suit the whole range of duct dimensions and insulation thicknesses. They can withstand the loads imposed by HVAC / building services ductwork at locations where ductwork
supports and hangers are installed.

Kingspan Kooltherm Flat Insulated Duct Support Inserts are flat rectangular strips of Kingspan Kooltherm Duct Insulation. They are used with rectangular and flat oval ductwork.

Kingspan Kooltherm Circular Insulated Duct Support Inserts are curved strips of Kingspan Kooltherm  Duct Insulation or Kingspan Kooltherm Pipe Insulation.They can not be used to support the compressive loads imposed by pipework carrying water or other liquids and should not be used in such applications.
