Tim­ber ve­neered board meets BCA fire re­quire­ments

Australasian Timber - - ASSOCIATIONS - By Peter Llewellyn Tech­ni­cal Rep­re­sen­ta­tive/Tim­ber Ve­neer As­so­ci­a­tion of Aus­tralia (TVAA)

THE BUILD­ING Code of Aus­tralia di­vides ma­te­ri­als into four groups with re­spect to their fire re­sis­tance, Ma­te­rial Group 1 hav­ing the high­est fire re­sis­tance while Ma­te­rial Group 4 has the low­est. The BCA’s Spec­i­fi­ca­tion C1.10 sets out the lo­ca­tions where each Ma­te­rial Group is re­quired, which varies ac­cord­ing to whether or not a sprin­kler sys­tem is in­stalled.

Gen­er­ally, ma­te­ri­als in Groups 1 and 2 are re­quired in ar­eas such as pub­lic cor­ri­dors, while only Group 1 ma­te­ri­als are per­mit­ted in more crit­i­cal ar­eas such as fire-iso­lated ex­its and lifts.

When de­sign­ing com­mer­cial build­ings spec­i­fiers are urged to make sure the prod­ucts they call up are prop­erly tested and cer­ti­fied. Com­monly avail­able ve­neers ap­plied to a par­ti­cle­board or MDF sub­strate fall into Ma­te­rial Group 3.

How­ever, mem­bers of the Tim­ber Ve­neer As­so­ci­a­tion of Aus­tralia can sup­ply fire re­tar­dant treated MDF with a va­ri­ety of ve­neer species that meet the BCA’s Group 2 re­quire­ments. Tests have been car­ried out to Aus­tralian Stan­dard re­quire­ments on be­half of the TVAA, and also by in­di­vid­ual TVAA mem­bers.

Some ve­neer species have even been tested to Group 1 level, and more species are ex­pected to be in­cluded in this group as fur­ther tests are con­ducted.

“Spec­i­fiers and/or cer­ti­fiers wish­ing to ob­tain as­sur­ance that tim­ber ve­neered board prod­ucts com­ply with the BCA’s fire re­sis­tance re­quire­ments can ob­tain copies of test re­ports from the TVAA, or from TVAA mem­bers who han­dle the rel­e­vant prod­ucts”, said As­so­ci­a­tion Pres­i­dent Rod Sharp.

Mr Sharp also em­pha­sised the im­por­tance of en­sur­ing that prod­ucts sup­plied to site match what has been spec­i­fied and dis­play the rel­e­vant grade mark­ings.
