Product Description

The Upper Facings

The upper facing of Kingspan Kooltherm® K10 Soffit Board is a tissue based facing bonded to the insulation core during manufacture.

The Lower Facing

The lower facing of Kingspan Kooltherm® K10 Soffit Board is a composite foil bonded to the insulation core during manufacture. The lower facing used on Kingspan Kooltherm® 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

The core of Kingspan Kooltherm® K10 Soffit Board is a premium performance CFC/HCFC–free rigid phenolic insulant of typical density 35 kg/m3.

CFC/HCFC–free

Kingspan Kooltherm® K10 Soffit Board is manufactured without the use of CFCs/HCFCs and has zero Ozone Depletion Potential (ODP).

Standard Dimensions 1200mm x 2400mm

Kingspan Kooltherm® K10 is available in the standard size of 1200mm wide by 2400mm long, and is readily available from us in the following most popular thickness ... 80mm.

We can also source the following sizes for larger orders ... 25mm, 30mm, 40mm, 50mm, 60mm. and 65mm 75mm, 80mm, 90mm. However, short lead times may apply.

Compressive Strength

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)

Durability

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.

Fire Performance

The rigid phenolic insulation core of Kingspan Kooltherm® 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 Kingspan Kooltherm® 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%

Fixing Directly to Concrete Soffits

Kingspan Kooltherm® K10 Soffit Board can be fully restrained to a concrete soffit by the use of 11 No. approved insulation fasteners with a minimum head diameter of 35 mm.

The fasteners should be evenly distributed over the whole area of the board and must offer a minimum 40 mm penetration into a solid substrate. Board joints should preferably be staggered.

Fixing to Timber Battens / Proprietary Grid Systems

Alternatively, a treated timber batten lay-out may be adopted if there is an uneven surface or mechanical services present and direct fixing is not possible. 50 mm x 25 mm battens should be placed at 600 mm centres to coincide with the edges / centre of the boards. The battens should be fixed to the soffit by the use of a suitable fixing method e.g. shot-fire may be considered.

Kingspan Kooltherm® K10 Soffit Board should then be fixed to the treated timber battens using suitable fixings. These should be placed at maximum 300 mm centres (maximum 200 mm when using nails into timber) in rows not greater than 600 mm apart.

Kingspan Kooltherm® K10 Soffit Board can also be fixed to a proprietary grid system comprising metal furring bars.

Manufacturer's advice should be sought regarding the type and required number of fixings for such applications. Please contact the Kingspan Insulation Technical Service Department
(see below) for further information.

Fixings should be not less than 12 mm from board edges.

Exposed joints should be covered with a suitable cover strip.

For aesthetic appearance, consideration may be given to the application of a PVC cover strip at board joints.

Cutting

Cutting should be carried out either by using a fine toothed saw, or by scoring with a sharp knife, snapping the board over a straight edge and then cutting the facing on the other side.
Ensure accurate trimming to achieve close butting joints and continuity of insulation.
