The Upper Facings
The upper facing of K10 Soffit Board is a tissue based facing bonded to the insulation core during manufacture.
The Lower Facing
The lower facing of K10 is a composite foil bonded to the insulation core during manufacture. The lower facing used on K10 Soffit Board has not been designed with the purpose of an aesthetic finish as its primary function.
Where appearance is critical, advice should be sought from the Kingspan Insulation Technical Service Department (see below).
The core of K10 is a premium performance CFC/HCFC free rigid phenolic insulant of typical density 35 kg/m3.
K10 is manufactured without the use of CFCs/HCFCs and has zero Ozone Depletion Potential (ODP).
Typically exceeds 100 kPa at 10% compression when tested to BS EN 826: 1996 (Thermal insulating products for building applications. Determination of compression behaviour).
Water Vapour Resistance
Modified to include board facings, the boards achieve a resistance far greater than 100 MN.s/g, when tested in accordance with BS 4370–2: 1993 (Methods of test for rigid cellular materials. Methods 7 to 9)
If correctly applied, Kingspan Kooltherm K0 Cavity Board has 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 rigid phenolic insulation core of K10 will achieve the results given below, which enable it to be classified by the Building Regulations as being Class 0 and as Low Risk by the Technical Standards in Scotland.
The fire rating of K10 Soffit boards when subjected to British Standard fire tests, will vary, depending on the particular application.
Test - BS 476–6: 1989 (Fire tests on building materials and structures. Method of test for fire propagation for products)
Result - Fire propagation index of Fire tests on building performance (1) not exceeding 12 and sub Index (i1) not exceeding 6 (for rigid phenolic insulation core)
Test - BS 476–7: 1997 (Fire tests on building materials and structures. Method of test to determine the classification of the surface spread of flame of products
Result - Class 1 rating
Test - BS 5111–1: 1974 (Smoke Obscuration)
Result - < 5%
