Premium performance cavity wall insulation, K8 phenolic foam boards with low emissivity foil facings are ideal for partial fill cavity walls constructions.
Common applications for this product include …
Cavity Wall (Partial Fill), Single Timber Frame Wall Lining, Steel Stud Frame Walls, Timber Frame Wall Lining, Timber Frame Walls Sheathing
The Board Facings
Faced on both sides with a low emissivity composite foil facing which is highly resistant to the transmission of water vapour. This reflective, low emissivity surface can effectively double the thermal resistance of the cavity in which the board is placed.
The core of K8 is a premium performance CFC/HCFC free rigid phenolic insulant of typical density 35 kg/m3.
K8 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, K8 Cavity Boards have an indefinite life. Their 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 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 K8 Cavity Board resist attack by mould and microbial growth and do not provide any food value to vermin.
The rigid phenolic insulation core of the K8 board 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 K8 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%
