Dukkaboard Original Panels are made from Hard Extruded Polystyrene (EPS) Foam which satisfies the requirements for BS EN13164:2008 and achieved a TR200 rating for bonding to cement mortar in accordance with BS EN1607:1997, coating with a flexible cement-based mortar and reinforced with an alkali-resistant fibreglass mesh. Dukkaboard XL is made from fibre-reinforced sheets which have been tested for Modulus of Rupture in accordance with the requirements for Category C material to BS EN 12467: 2008.
Delivery and Handling
The sheets should be stored flat, under cover, and on a dry, level surface. Stacks of loose boards should not exceed one metre in height.
Properties in relation to fire
The boards will not adversely change the fire resistance of the wall on which they are installed. When tested to BS 476-6: 1989, samples of Dukkaboard XL gave fire propagation indices (I) of 0.0, 0.1 and 0.0 respectively and sub-indices (i1) of 0.0, 0.1 and 0.0 respectively. When tested to BS 476-7: 1997, Dukkaboard XL achieved a Class 1 result. When tested to BS EN ISO 1182: 2010 and BS EN 13823: 2010, samples of Dukkaboard Original and XL achieved a reaction to fire classification in accordance with BS EN 13501-1: 2007 of A2-s1, d0. Therefore, Dukkaboard XL is classified as ‘non-combustible’ as defined in the various national Building Regulations.
