Residential applications - The clearance between Earthwool glasswool insulation and recessed downlights:
This section used AS/NZS 60598.2.2:2001 which is cited in NZBC C/AS1 and C/AS2. As AS/NZS 60598.2.2:2016 is not cited at time of writing, it is not used in this section. If you use AS/NZS 60598.2.2:2016 as an alternative solution modify this section accordingly. AS/NZS 60598.2.2:2001 and NZS 4246 both state that loose-fill insulation shall not abut or cover recessed luminaires (downlights) unless specifically allowed by the luminaire manufacturer.
Non-Residential applications - The clearance between Earthwool glasswool insulation and all recessed light fittings:
Insulation abutting or covering recessed luminaires (downlights) must pass the needle flame test to AS/NZS 60695.11.5.
NZBC C/AS2 regulates that non-residential installations must have 100mm clearance, unless it passes the needle flame test. Earthwool glasswool complies with AS/NZS 60695.11.5, refer to clause FIRE PROPERTIES.
This section uses AS/NZS 60598.2.2:2001 which is cited in NZBC C/AS1 and C/AS2. As AS/NZS 60598.2.2:2016 is not cited at time of writing, it is not used in this section. If you use AS/NZS 60598.2.2:2016 as an alternative solution modify this section accordingly.
AS/NZS 60598.2.2:2001 and NZS 4246 both state that loose-fill insulation shall not abut or cover recessed luminaires (downlights) unless specifically allowed by the luminaire manufacturer.
Insulation may need to have a gap to some mechanical and electrical services and equipment, including ducts and chimneys. The gaps should be to the NZS 4246 based tables below or to the equipment manufacturer requirements if they require larger gaps. Smaller gaps to manufacturer requirements can be used for equipment specifically manufactured with heat shielding or similar (excludes light fittings). Installed gap not to be more than 50mm bigger than the required gap.
The following tables are subject to:
INSULATION CLEARANCES FROM RECESSED LIGHT FITTINGS
Type of fitting | Minimum insulation clearance | Comments |
Unmarked recessed | 100mm | New or old unmarked & unknown fittings and/or insulation. Secure insulation. Do NOT cover fittings. |
CA 80, CA 90 or CA 135 recessed | Abut in residential. 100mm in others | Do NOT cover the fittings. For residential loose fill insulation, refer to NZS 4246 figure 4. |
IC, IC-F or IC-4 recessed | Abut in residential. 100mm in others | Cover in residential only except for residential loose fill insulation, refer to NZS 4246 figure 7. Do NOT cover in others |
Independent control gear | Place on top of insulation and 50mm from fitting | If not on top allow 50mm clearance to insulation, do not cover. Includes, transformers, ballasts & drivers etc. Maintain clearance by placing guard around control gear, refer to NZS 4246 figure 15. |
Surface fittings not exposed to insulation | Nil | Where surface fittings are isolated from insulation by appropriate linings. Excludes high heat fittings. |
Surface fittings & exposed insulation | 200mm | This is exposed insulation to any part of the exposed fitting & bulb/tube (e.g. exposed light in an unlined basement). Secure insulation. |
Note; CA 80, CA135, IC & IC-F are cited in NZBC C/AS's and AS/NZS 60598.2.2: 2001. But CA 90, CA135, IC & IC-4 only are in AS/NZS 60598.2.2: 2016, which makes CA 90 & IC-4 alternative solutions. However all clearances stated comply with AS/NZS 60598.2.2: 2016 for residential.
FOR MINIMUM INSULATION CLEARANCES TO INBUILT RECESSED HOT APPLIANCES - REFER TO NZS 4246
INSULATION CLEARANCES FROM EXTRACTS, VENTS, PIPES & ROOF UNDERLAY
Application | Minimum insulation clearance | Comments |
Ducted fan motors | 50mm | Includes ducted rangehoods, extractors etc. Applies to the motor unit and electrical enclosures (not the ducts). |
Ducted fan ducts | Abut | Excludes motor unit and electrical enclosures. |
Unducted fan motors usually discharging to ceiling space | 200mm | Includes unducted, rangehoods, extractors etc, discharging into roof space. To prevent debris falling into motor. Clearance may be able to be reduced, by providing a fixed barrier around the vent. |
Passive vents (still in use) | 200mm | To prevent debris falling through. Clearance may be able to be reduced, with more cohesive insulation, like some of the rigid plastic types or providing a fixed barrier around the vent. |
Plumbing penetrations through floors | 100mm | Keep gap between pipe penetration and floor insulation in case of leaks. |
Roofing material/underlay | 25mm | From underside of roofing or flexible roofing underlay, to prevent wicking. |
NOTE - unducted fans (bathroom & kitchen extracts) and passive vents discharging into ceiling spaces are not recommended and are probably difficult to achieve under the NZBC, but may be encountered in existing buildings.
Modify this whole clause to suit the project requirements.
These tables in part, may repeat some information that is also in other clauses, usually it is not identical and provides further detail. It is an option to delete the repeated information from here or the other related clause if it is necessary, or leave both instances to reinforce the point.
Friction fit insulation batt between floor joists and butt joins tightly to ensure there are no gaps. Staple into the joists at 200mm intervals on both sides of the joist. For pole houses increase the staples to 100mm centres and tape the joins as required.
Ensure the heavier duty grey film is stapled 65mm below the floor, facing down, and that it is pulled tight to provide smooth consistent surface. Follow the manufacturer installation instructions and refer to NZS 4246 for further guidance on the installation of underfloor insulation.
Staple insulation between floor joists and butt joins tightly to ensure there are no gaps. Staple into the joists at 200mm intervals on both sides. Ensure the facing is 75mm below the floor, facing down, and that it is pulled tight so that there are no bulges in accordance with the installation instructions. Refer to NZS 4246 for installation guidelines and Earthwool® glasswool insulation underfloor Installation Instructions.
Friction fit wall batt between framing members and linings. Cut on site to fill cavity and provide a close even fit. When cutting to fill a void, oversize by up to 10mm to ensure a tight fit. Ensure there is a friction fit on all faces of the insulation. If cavity depth is greater than the insulation nominal thickness, fix or strap the product to secure in accordance with installation instructions. Cut into smaller pieces for smaller spaces and around penetrations to achieve efficient thermal performance. Do not fold, tuck or compress the insulation. Refer to NZS 4246 for installation guidelines and Earthwool® glasswool insulation Product Data sheets listed in the CodeMark, for detailed installation instructions.
Friction fit wall batt inside the steel studs and cut on site to fit nog spacing. Fill cavity and provide a close even fit. When cutting to fill a void, oversize by up to 10mm to ensure a tight fit. Do not fold, tuck or compress the insulation. Cut to smaller pieces for smaller spaces and around penetrations to achieve efficient thermal performance.
Friction fit insulation between framing members and linings. Cut on site to fill cavity and provide a close even fit. When cutting to fill a void, oversize by up to 10mm to ensure a tight fit. Ensure there is a friction fit on all faces of the insulation. If cavity depth is greater than the insulation nominal thickness, fix or strap the product to ensure the insulation is installed hard against the flooring or the ceiling lining. Cut into smaller pieces for smaller spaces and around penetrations to achieve efficient thermal performance. Refer to NZS 4246 for installation guidelines.
Friction fit insulation between framing members. Cut across the roll to fit nogs and small spaces around penetrations. Leave no gaps and maintain full thickness of insulation over the whole of the installation. Leave gap around metal flues to the manufacturer requirements.
Loose lay over ceiling framing and between truss chords. Fit securely around all penetrations, leave clearances where required. Cut ceiling roll as required.
Friction fit first layer of ceiling insulation roll parallel to and between ceiling framing members. Run a second layer of insulation roll at 90° to and over the first layer over framing members. Use a sharp craft knife to cut to required size to fit nogs and small spaces around penetrations. Leave no gaps and maintain full thickness of the insulation over the whole of the installation. Leave gap around metal flues to the manufacturer requirements.
Note: 90mm high density (wall) product can be used as the first layer of a double layer system layer and is extremely effective as it is the same height as the bottom chord of the truss or joist.
Where perimeter of ceiling space is too low to allow full depth of insulation plus the 25mm air gap to the underlay, provide reduced perimeter insulation to NZS 4246.6.2 and maintain the 25mm gap.
Friction fit insulation between joists/rafters. Use a sharp craft knife to cut to required size or around penetrations if required. Maintain a minimum clearance of 25mm between the insulation and the roofing underlay, to NZS 4246 clause 6.2.10, except where a solid timber (or plywood) substrate is used under the roof cladding.
This is to prevent wicking. Should the 25mm insulation gap need to be reduced, it will be specific design.
Note that some roofs may require a ventilation gap under a solid timber substrate.
Modify clause to suit project requirements.
Friction fit insulation between joists/rafters. Use a sharp craft knife to cut to required size or around penetrations if required. Maintain a minimum clearance of 20mm between the underside of the substrate (plywood etc) and any insulation to NZBC E2/AS1 clause 8.5.2
Should the 20mm insulation gap need to be reduced, it will no longer be an Acceptable Solution but an Alternative Solution.
Modify clause to suit project requirements.
Friction fit batt, or roll, in place to completely fill the whole of the cavities, after the wall lining is fixed to one side of the partition. Slightly oversize to retain friction fit. Keep clean and undamaged until closed in. Close in as soon as possible after fixing.
