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 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.
This soffit board is a premium performance rigid phenolic insulation board, designed for use under structural ceilings. The lightweight product achieves a thermal conductivity as low as 0.021 W/m.K and addresses the stringent safety requirements with a Class O / Low Risk fire rated insulation core and negligible smoke obscuration.
