Fire Safety

When tested(1) to DD CEN/TS 1187 : 2012, Test 4, a system comprising 12 mm calcium silicate board, a coat of Liquiflex Pro and an overcoat of Liquitop, achieved a classification of BROOF(t4) under BS EN 13501-5 : 2005.

On the basis of data assessed, the system listed in section 2.1.1 of the BBA Certificate will be unrestricted by the documents supporting
the national Building Regulations with respect to proximity to a boundary. Restrictions may apply at junctions with compartment walls.

A roof incorporating the system will also be unrestricted under the national Building Regulations in the following circumstances:
• a roof garden covered with a drainage layer of gravel 100 mm thick and a soil layer 300 mm thick
• when protected by an inorganic covering (eg gravel or paving slabs) listed in the Annex of Commission Decision 2000/553/EC
• when used in an irrigated roof garden or green roof specification.

The designation and permissible areas of use of other specifications must be confirmed by reference to the
requirements of the documents supporting the national Building Regulations.

On the basis of data assessed, the system may be restricted by the documents supporting the national Building Regulations with respect to proximity to a boundary in some cases.

If allowed to dry, plants used may allow the spread of flame across the roof. This must be taken into
consideration when selecting suitable plants for the roof. Appropriate planting, irrigation and/or protection must be applied to ensure the overall fire rating of the roof is not compromised.
