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.

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.

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 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).

LIGHT FITTINGS

INBUILT RECESSED HOT APPLIANCES

EXTRACTS, VENTS, PIPES & ROOF UNDERLAY

Lay at right angles across the rafters/roof joists (under purlins).  Pull tight and fix.

Lay at right angles across the framing at a minimum of 300mm centres, staple tape to each framing member with stainless steel staples.

Cut insulation using a sharp craft knife.

Friction fit ecoinsulation® glasswool Thermal Ceiling segments between ceiling framing members, leaving no gaps and maintaining full thickness of insulation over whole installation.  R7.0 Ceiling batt is designed to expand over truss chords / ceiling joists without the need for notching of batts.  Cut insulation pieces as required to fill small spaces, gaps around penetrations and other obstructions.  Without compressing, tuck insulation behind wiring, plumbing or ductwork.  Leave gap around metal flues to the manufacturer requirements.

Loose lay ecoinsulation® glasswool Thermal Ceiling segments over the ceiling framing and between truss chords, leaving no gaps and maintaining full thickness of insulation over whole installation.  Cut insulation pieces as required to fill small spaces, gaps around penetrations and other obstructions.  Without compressing, tuck insulation behind wiring, plumbing or ductwork.  Leave gap around metal flues to the manufacturer requirements.

Friction fit ecoinsulation® glasswool Thermal Ceiling segments between ceiling framing members, level with the top of the framing.  Loose lay a layer of ecoinsulation® Thermal Ceiling roll over the ceiling framing, laid at 90° to the framing direction.  Leave no gaps and maintaining full thickness of insulation over whole installation.  Cut insulation pieces as required to fill small spaces, gaps around penetrations and other obstructions.  Without compressing, tuck insulation behind wiring, plumbing or ductwork.  Leave gap around metal flues to the manufacturer requirements.

Friction fit ecoinsulation® glasswool Thermal Ceiling segments between roof rafters, flush with the face of the rafter, leaving no gaps and maintaining a continuous clearance of 25mm minimum between the insulation and the roofing membrane (underlay).  Cut insulation pieces as required to fill small spaces, gaps around penetrations and other obstructions.  Without compressing, tuck insulation behind wiring, plumbing or ductwork.  Leave gap around metal flues to the manufacturer requirements.

Measure distance between studs and cut ecoinsulation® glasswool Thermal and Acoustic Wall segments to friction fit between framing members with front face of insulation flush with framing.  Leave no gaps and maintaining full thickness of insulation over whole installation.  If cavity depth is greater than the insulation nominal thickness, fix or strap the insulation to secure.  Cut insulation pieces as required to fill small spaces, behind outlet boxes, gaps around penetrations and other obstructions.  Without compressing, tuck insulation behind wiring, plumbing or ductwork.

Measure distance between studs and cut ecoinsulation® glasswool Thermal and Acoustic Wall segments to friction fit with one side of the segment in the metal C-channel and other edge butted against the next metal stud.  Leave no gaps and maintaining full thickness of insulation over whole installation.  If cavity depth is greater than the insulation nominal thickness, fix or strap the insulation to secure.  Cut insulation pieces as required to fill small spaces, behind outlet boxes, gaps around penetrations and other obstructions.  Without compressing, tuck insulation behind wiring, plumbing or ductwork.

Friction fit ecoinsulation® glasswool Thermal and Acoustic Wall between floor joists, leaving no gaps and maintaining full thickness of insulation over whole installation.  Cut insulation pieces as required to fill small spaces, gaps around penetrations and other obstructions.  Without compressing, tuck insulation behind wiring, plumbing or ductwork where possible.

Friction fit ecoinsulation® glasswool FloorShield Thermal Underfloor segments between floor joists with wind-wash barrier facing downwards, leaving no gaps.  Strap or support with insulation saddles.
