GENERAL

If you have pre-customised this work section using the "questions and answers" provided as part of the downloading process, it may be necessary to modify some clauses to suit the final project-specific version.

The section must still be checked and customised to suit the project being specified, by removing any other irrelevant details and adding project-specific details and selections.

 

This section relates to the supply and installation of ecoinsulation® glasswool thermal and acoustic insulation.

 

It includes:

Modify / expand this clause to suit requirements of the final version of the section.

Note: Retrofit exterior wall or internal firewalls insulation requires a Building Consent to Building Act 2004, schedule 1, clause 13.

 

For compliance of the building thermal envelope use:

The Acceptable Solutions contain a Schedule and a Calculation method & the Verification Methods contain a Modelling method for determining construction R-values required.

 

ecoinsulation® glasswool insulation is manufactured by Knauf Insulation for Eco Insulation Energy and Installation Ltd using bio-soluble glasswool with up to 80% post-consumer recycled glass, bonded with ECOSE® Technology, a binder based on rapidly renewable materials instead of petro-based chemicals, with no added formaldehyde, dyes or artificial colours.  ecoinsulation® glasswool insulation has zero Ozone Depletion Potential (ODP), and zero Global Warming Potential (GWP).

Installation - generally
3.4
STANDARDS AND TOLERANCES

Refer to the general section 1270 CONSTRUCTION for general requirements.

Amend this clause to describe specific standards and tolerances to be achieved in carrying out this part of the work.  Although such tolerances are typically included in standards (NZS, AS/NZS etc) in certain circumstances it is worth restating these in this clause.

3.5
INSTALLATION GENERALLY

Lay, install, fit and fix insulation without gaps, tucks, folds and over compaction to NZBC H1/AS1 or AS2 and ecoinsulation® requirements and installation instructions.  For all housing and buildings up to 300m², install in accordance to NZS 4246 sections 5 Walls, 6 Ceilings & Roofs, 7 Underfloor - Suspended Framed Floors and 10 Concrete Slab-on-Ground Insulation, for residential light timber or steel framed buildings.  Allow insulation to re-loft/relax prior to installation.  Do not cover vents.  Lift up electrical wires, lighting transformers/controllers and lay the insulation underneath.

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.

3.6
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 Electricity (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.

3.7
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
  • New fittings can only be labelled - CA 80, CA 90, CA 135, IC, IC-F & IC-4

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 Electricity (Safety) Regulations, Schedule 4 and NZS 4246).

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.

3.8
INSULATION CLEARANCES - GENERAL

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).

Note: NZBC H1/AS1-AS2, 2.1.2 Schedule Method, for roofs with a roof space where the insulation is installed over the horizontal ceiling, the minimum construction R-values for a roof in all climatic zones may be reduced to R3.3 for a distance of up to 500mm from the outer edge of the ceiling perimeter where space restrictions do not allow full-thickness insulation to be installed.

Thickness:

~mm

Size:

~mm x ~mm

Density:

~kg/m³

Suitable for external wall and internal wall applications.

Note: To meet NZBC G6/AS1, acoustic insulation must be 75mm minimum thickness and 10kg/m³ minimum density.  The use of insulation below 90mm thickness as a proposed alternative solution requires field testing to NZBC G6/VM1 to demonstrate compliance.

 

Application:
