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.
