These standards give minimum building element thermal resistance (R-values). Achieving these will depend on the quality of the insulation.

CAUTION: Electrical cables and equipment partially or completely surrounded with bulk thermal insulation may overheat and fail. This applies to wiring installed prior to 1989.

3.5
RECESSED LIGHT FITTINGS - NON-RESIDENTIAL

Non-residential recessed light fittings to AS/NZS 3000, 4.5.2.3.5;

  • Existing fittings or retrofit situations, fittings maybe unmarked
  • New fittings can only be labelled - CA 80, CA 90, CA 135, IC, IC-F, IC-4, NON-IC or Do-not Cover

Refer to clause INSULATION CLEARANCES GENERALLY for clearances.

Insulation abutting or covering recessed downlights must pass the needle flame test to AS/NZS 60695.11.5, as required by AS/NZS 60598.2.2: 2001 (cited in Electrical (Safety) Regulations, Schedule 4).

 

Note; CA 80, CA135, IC, IC-F & NON-IC are cited in AS/NZS 60598.2.2: 2001.  But CA 90, CA135, IC, IC-4 and Do-not Cover, are only in AS/NZS 60598.2.2: 2016, which makes CA 90, IC-4 & Do-not Cover, alternative solutions.  However all clearances stated comply with AS/NZS 60598.2.2: 2016 and AS/NZS 3000:2018.

 

IC-4 due to low/zero air transfer requirements, is generally recommended for unventilated roof spaces, like skillion/compact and Passive House roofs.

3.6
RECESSED LIGHT FITTINGS - RESIDENTIAL

Residential recessed light fittings to AS/NZS 3000, 4.5.2.3.5;

  • Existing fittings or retrofit situations, fittings maybe unmarked

Note; CA 80, CA135, IC & IC-F are cited in AS/NZS 60598.2.2: 2001.  But CA 90, CA135, IC, & IC-4, are only in AS/NZS 60598.2.2: 2016, which makes CA 90 & IC-4 fittings alternative solutions.  However all insulation clearances for all the above fittings comply with NZS 4246, which complies with NZBC H1/AS1.

 

IC-4 due to low/zero air transfer requirements, is generally recommended for unventilated roof spaces, like skillion/compact and Passive House roofs.

3.7
INSULATION CLEARANCES - GENERALLY

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:

  • The requirements of NZS 4246.
  • The insulation is exposed to the source of heat or equipment etc.
  • Insulation, has passed the needle flame test to AS/NZS 60695.11.5 and/or is non-combustible.
  • Gaps to hot surfaces may have to be increased with non-compliant insulation and plastic/polymeric type insulation (EPS, XPS, PIR, etc), check with insulation manufacturer.
  • Gaps to hot surfaces may be able to be reduced with non-combustible insulation, check with equipment manufacturer.
  • "Secure insulation" if required means, glue, mechanical fix, or provide fixed barriers at gap edge of insulation to hold in place.  Rigid or semi rigid insulation may only need a firm friction fit (secure loose pieces).

CAUTION: Electrical cables and equipment partially or completely surrounded with bulk thermal insulation may overheat and fail. This applies to wiring installed prior to 1989.

Installation - Underfloor
3.8
UNDERFLOOR (WRAPPED)

Friction fit Thermal Underfloor between floor joists and butt joins tightly to ensure there are no gaps.  Staple-fix the insulation into the joists at 200mm centres on both sides of the joist. For pole houses increase staple fixing to 100mm centres, and tape the joins as required.

Ensure the wind-wash barrier is facing downward, and that it is pulled tight to provide smooth consistent surface, without tearing.  Follow the manufacturer installation instructions and refer to NZS 4246 for further guidance, and ecoinsulation® glasswool insulation Thermal Underfloor installation instructions.

3.9
FACED UNDERFLOOR

Staple Faced Thermal Underfloor rolls 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 wind-wash barrier is face downward, and that it is pulled tight.  Refer to NZS 4246 for installation guidelines, and ecoinsulation® glasswool insulation Faced Thermal Underfloor installation instructions.

Installation - Walls
3.10
TIMBER FRAMING

Friction fit 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 ecoinsulaton® glasswool insulation Product Data Sheets, for detailed installation instructions.

3.11
STEEL FRAMING

Friction fit inside the steel framing 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.

Installation - Ceiling
3.12
BETWEEN CEILING FRAMING - SEGMENTS

Friction fit ecoinsulation® glasswool insulation Thermal ceiling segment between framing members.  Cut across the roll for fit to 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.

3.13
OVER CEILING FRAMING - ROLLS

Loose lay ecoinsulation® glasswool insulation Thermal ceiling roll insulation over the ceiling framing and between truss chords.  Cut across the insulation roll as required to fit securely around all penetrations and small spaces, leave clearances where required.
