Kingspan Kooltherm K3 Floorboard_150

Category: Panel/Roll
Type: Thermal insulation
Application area: Floor,

This performance thermal insulation board is faced on both sides with a plain (coated) glass tissue, autohesively bonded to the insulation core. The core is a premium performance CFC/HCFC – free rigid phenolic insulant with a typical density of 35kg/m3. The board has a compressive strength that typically exceeds 120 kPa. The Board Facings K3 Floorboard is faced with a composite foil facing, similarly bonded. The Core The core of Kingspan Kooltherm® K3 Floorboard is a premium performance rigid thermoset modified resin insulant manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). Compressive Strength The compressive strength of Kingspan Kooltherm® K3 Floorboard typically exceeds 120 kPa at 10% compression, when tested to BS / I.S. EN 826: 1996 (Thermal insulating products for building applications. Determination of compression behaviour). Water Vapour Resistivity Kingspan Kooltherm® K3 Floorboard produced at Kingspan Insulation’s Pembridge manufacturing facility typically achieves a resistivity greater than 300 MN.s/g.m when tested in accordance with BS EN 12086: 1997 / I.S. EN 12086: 1998 (Thermal insulating products for building applications Determination of water vapour transmission properties).Adjusted for the effect of board joints, the product produced at Kingspan Insulation’s Castleblayney manufacturing facility achieves a resistance far greater than 100 MN.s/g when tested in accordance with the above standard. Durability If correctly installed, K3 Floorboard can have an indefinite life. Its durability depends on the supporting structure and the conditions of its use. Resistance to Solvents, Fungi & Rodents The insulation core is resistant to short–term contact with petrol and with most dilute acids, alkalis and mineral oils. However, it is recommended that any spills be cleaned off fully before the boards are installed. Ensure that safe methods of cleaning are used, as recommended by the suppliers of the spilt liquid. The insulation core is not resistant to some solvent–based adhesive systems, particularly those containing methyl ethyl ketone. Adhesives containing such solvents should not be used in association with this product. Damaged boards or boards that have been in contact with harsh solvents or acids should not be used. The insulation core and facings used in the manufacture of K3 Floor boards resist attack by mould and microbial growth, and do not provide any food value to vermin.
