there is no requirement to enclose the subfloor space or to protect flooring materials from bushfire attack. However,

should combustible materials be stored, it is recommended the area be protected as materials stored in the subfloor

space may be ignited by embers and cause an impact to the building)

There is no requirement to enclose the subfloor spaces of verandas, decks, steps, ramps or landings.

C5.7.1 Spaced decking is nominally spaced at 3 mm (in accordance with standard industry practice); however, due to the

nature of timber decking with seasonal changes in moisture content, that spacing may range from 0-5 mm during

service. The preferred dimension for gaps is 3 mm (which is in line with other permissible gaps) in other parts of this

Standard. It should be noted that recent research studies have shown that gaps at 5 mm spacing afford opportunity for

embers to become lodged in between timbers, which may contribute to a fire. Larger gap spacings of 10 mm may

preclude this from happening but such a spacing regime may not be practical for' a timber deck.

(a) gutters, with the exception of box gutters; and

(b) downpipes.

If installed, gutter and valley leaf guards shall be non-combustible.

Box gutters shall be non-combustible and flashed at the junction with the roof with noncombustible material.

5.7 VERANDAS, DECKS, STEPS, RAMPS AND LANDINGS

5.7.1 General

Decking shall be either spaced or continuous (i.e., without spacing).

There is no requirement to enclose the subfloor spaces of verandas, decks, steps, ramps or landings.

CS. 7.1 Spaced decking is nominally spaced at 3 mm (in accordance with standard industry practice); however, due to the

nature of timber decking with seasonal changes in moisture content, that spacing may range from 0-5 mm during

service. The preferred dimension for gaps is 3 mm (which is in line with other 'permissible gaps') in other parts of this

Page 18: APPENDICES COMPLIANCE STATEMENT - eservices.somerset.qld ... · APPENDICES – COMPLIANCE STATEMENT Code Compliance - Detailed Assessment against applicable codes / Australian standards

Standard. It should be noted that recent research studies have shown that gaps at 5 mm spacing afford opportunity for

(measured vertically) from the surface of the deck (see Figure D2, Appendix D) shall be made from

(a) non-combustible material; or

(b) bushfire-resisting timber (see Appendix F); or

(c) a timber species, as specified in Paragraph E1 and listed in Table E1 of Appendix E;

(d) PVC-U; or

(e) a combination of any of Items (a), (b), (c) or (d) above.
