Those fronting Bells Road (double storey requirement) within <50m of Bells Road extension.
Dwelling facades constructed within <80m of the Bells Road extension with direct exposure to traffic noise. Generally, the expectation will be external facades will receive up to 90 degree angle of view of the roadway due to other building structures constructed at closer setbacks to the roadway.
Dwelling facades constructed within <80m of the Bells Road extension which are well shielded from traffic noise by structures including other dwellings or buildings associated with an independent use. Generally, the expectation will be external facades will receive <90 degree angle of view of the roadway due to the shielding elements.
Façade Wall • External façade walls must be constructed to include masonry brick veneer combined with an internal stud wall clad with 13mm plasterboard. • The cavity must include fibreglass insulation (min. 75mm thick x 14kg/m3) and the wall system must be well sealed using resilient mastic (eg Sikaflex Pro.) • Lightweight construction will not be suitable for dwellings within this category. Roof/Ceiling • Metal deck roofing (min. 0.48mm thick) or conventional roof tile system combined with conventional building blanket incorporating insulation and sisalation. • Internally, the system must include a suspended ceiling constructed using 2no. 13mm FR plasterboard with fibreglass insulation (min. 75mm thick x 14kg/m3) overlays. • The suspended ceiling system must include a 250mm air gap and be substantially unpenetrated unless penetrations are treated acoustically so as not to influence the overall performance of the system. Glazing • Double glazing element to be 6.5mm VLAM Hush / 10mm air gap / 8.5mm VLAM Hush. The proposed configuration must include the nominated glazing and form part of a system achieving a minimum acoustic performance of Rw 37 or, • Double glazing system incorporating 10.5mm VLAM Hush / 8mm air gap (argon) / 6mm glass and achieving Rw 39 may also be suitable but will need to be reviewed by an acoustic consultant to be equal or better in spectral performance to the 6.5mm VLAM Hush / 10mm air gap / 8.5mm VLAM Hush prior to approval. • Internal rooms associated with dwellings are to be considered as independent spaces with glazing to be limited in accordance with the following parameters: - Bedrooms must only include a single facade which incorporates glazing. Where bedrooms are located on a corner, the second facade must be a solid construction without any glazed elements. The glazed sections within the single facade must not make up more than 20% of that single facade (not including second facade). - Living areas can include glazing elements on one or two facades when located on a corner, however the glazed elements must not be greater than 30% of each facade. • Glazing facing away with no angle of view of the roadway can be constructed as for Category B. Access Door • Access doors must open into common ‘non noise sensitive’ corridors. • Construction to be 40mm solid core timber door fitted with suitable acoustic perimeter seals. • As a minimum, acoustic seals to include Raven RP10 to tops and sides of doors, combined with Raven RP38 or RP71 to door thresholds. Double doors should be avoided.
Façade Wall • Masonry facades including brick veneer when combined with internal stud walls clad with 13mm plasterboard will adequately address external noise intrusion. • Should light weight construction be adopted, facade walls will be constructed using steel studs (min. 92mm) clad internally using 1no. 13mm FR plasterboard, and externally using 9mm CFC. • For both the masonry and light weight options, the cavity must include fibreglass insulation (min. 75mm thick x 14kg/m3) and the wall system must be well sealed using resilient mastic (eg. Sikaflex Pro.) Roof/Ceiling
Façade Wall • Masonry facades including brick veneer when combined with internal stud walls clad with 13mm plasterboard will adequately address external noise intrusion. • Should light weight construction be adopted, facade walls will be constructed using steel / timber studs (min. 90mm) clad internally using 1no. 13mm plasterboard, and externally using 9mm CFC. • For both the masonry and light weight options, the cavity must include fibreglass insulation (min. 75mm thick x 14kg/m3) and the wall system must be well sealed using resilient mastic (eg. Sikaflex Pro.)
• Metal deck roofing (min. 0.48mm thick) or conventional roof tile system combined with conventional building blanket incorporating insulation and sisalation.
Roof Ceiling
• Internally, the system must include a suspended ceiling constructed using 1no. 13mm plasterboard with fibreglass insulation (min. 75mm thick x 14kg/m3) overlays.
• Conventional thermal double glazing consisting of 6mm glass, 12mm air gap and 6mm glass or single glazing comprising 6.38mm laminated glass. The system must achieve a minimum acoustic performance of Rw 31.
• The suspended ceiling system must include a 200mm air gap and be substantially unpenetrated unless penetrations are treated acoustically so as not to influence the overall performance of the system. Glazing • Acoustic double glazing system consisting of 10mm glass, 12mm air gap and 6mm glass or single glazing comprising 10.38mm laminated glass. • The system must achieve a minimum acoustic performance of Rw 33. • Internal rooms associated with dwellings are to be considered as independent spaces with glazing to be limited in accordance with the following parameters: - Bedrooms can include glazing elements on one or two facades when located on a corner, however the glazed elements must not be greater than 50% of each facade. - Living areas can include glazing elements on one or two facades when located on a corner, however the glazed elements must not be greater than 50% of each facade. • Glazing facing away with no angle of view of the roadway can be constructed as for Category C. Access Door • As for Category A, unless doors are facing away with no angle of view of the roadway then they can be constructed as for Category C. - Category C Access Door “Solid core timber door well fitted to opening with minimal gaps around the perimeter and conventional weather seals”
