Refer to clause INSULATION CLEARANCES GENERALLY for clearances.

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).

EXTRACTS, VENTS, PIPES & ROOF UNDERLAY

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.

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.

Friction fit the ecoinsulation® glasswool insulation acoustic segments in walls, ceilings, and mid-floors to figures 1-5, NZBC G6/AS1 - Airborne and impact sound.  Alternatively, to specific design or NZBC G6/VM1.  For walls, install insulation after one side of the wall lining is fixed to the partition.  Slightly oversize to retain friction fit.  Keep clean and undamaged until closed in.  Close in as soon as possible after fixing.

Refer to 1270 CONSTRUCTION for completion requirements and if required commissioning requirements.

ecoinsulation® glasswool insulation packaging is recyclable.
