materials have been supplied as ordered and are free from damage or faults.
Check that all product is supplied from one batch. Due to batch to batch
variation, we do not recommend joining different batch lots as this could
result in colour variation. The batch number can be found on the product label
sticker attached to each pack.
Any variations must be reported to GreenStuf prior to commencing the
installation. No claims will be accepted where the job continues with obvious
faults, and no consultation with GreenStuf has taken place. If you cut or
install the product, you have accepted the quality.
Safety Instructions
GreenStuf 100% polyester insulation is completely safe and user-friendly;
therefore, no protective clothing or specialist equipment is required to
handle this product.
GreenStuf is a non-irritant, non-toxic, and non-allergenic insulation. This
ensures no skin, throat or lung irritation during or post-installation.
GreenStuf Material Safety Data Sheet (MSDS) contains further safety
information on the handling of GreenStuf insulation. A copy of the MSDS is
available on request from your account manager.
CAUTION: Electric cables and equipment partially or fully surrounded with
any bulk thermal insulation may overheat and fail. Care must be taken to
ensure this risk is avoided. Guidance is set out in AS/NZS 3000. Wiring Rules.
Ensure you understand your responsibility before you begin the installation.
Lights and Electrical Appliances: Regardless of the type of insulation
being used, there can be significant fire risk associated with some lighting
and appliances, especially halogen type bulbs as these can produce very high
temperatures and may require clear ventilation space to operate safely.
Careful selection, as well as correct installation of the light
fitting/appliance and any surrounding insulation, is critical. Minimum
clearances to all bulk insulation may be required for selected lighting or
appliance/s.
This must be checked with the lighting/appliance manufacturer prior to
installation. Any appliance, including recessed type lights and transformers,
should not be covered or surrounded with insulation unless allowed by the
appliance manufacturer. If in doubt, leave a clear 100 mm space between the
fitting/appliance and the edge of the insulation. Refer to a registered
electrician for further guidance.
GreenStuf AAB has been tested and assessed as complying with the requirements
of IEC 60695-11-5 Needle-flame test.
For more information, please refer to our Insulating Safely around Downlights
Factsheet.
Clearances: Cut GreenStuf AAB to fit neatly around fire collars, pipes
and penetrations. Do not cover the face of fire collars as these must be
exposed to activate in a fire situation.
Leave specified and required clearances to light fittings, ancillary equipment
and electrical accessories.
Product Format: GreenStuf AAB is supplied as standard 1200 mm (+20/-0 mm)
x 2400 mm (+100/-0 mm) sheets in white or black colour. Custom sizes and
colours may be available on request but are subject to minimum order
quantities.
GreenStuf AAB is non-woven, so some colour blending variation is typical batch
to batch and throughout each production lot. This is an inherent feature of
the product and not considered a manufacturing fault.
The product nominal thickness is the off-line manufactured thickness.
Packaging, storage and handling may affect the “out of the pack” thickness.
This is not considered a manufacturing fault. If thickness is critical to a
particular installation, please discuss your requirements with your account
manager.
Insulation Fasteners: GreenStuf AAB can be installed using mechanical
fixings. These can be either shot fired insulation anchors (such as Hilti) or
the insulation pin style of insulation anchor with a one way washer or dome.
The fastener length must be equal to the thickness of the GreenStuf AAB
insulation panels to avoid compression and pillowing of the insulation sheet.
Use fixings in accordance with the manufacturer’s technical information and
instructions.
Insulation Anchor Penetrations: When using shot fired insulation anchors,
we recommend that penetrations are created for each insulation anchor point
prior to the installation of each sheet. This will help ensure good take of
the anchor in the substrate and a tight and neat install of the GreenStuf AAB
sheet.
Penetrations for the insulation anchors and fixings can be formed using a hot-
knife, insulation knife or a pointed chisel type drill bit. When using a
battery/power drill, ensure the drill clutch is engaged to minimise the risk
of twist-up should the bit bind in the fibres. Bring the drill to full speed
before starting the penetration and use light pressure throughout the cut.
Adhesives: GreenStuf AAB can be direct fixed using adhesives. GreenStuf
recommends a contact-type adhesive or full curing panel adhesive for applying
GreenStuf AAB to most common substrates. Prior to commencing work, we
recommend contacting your adhesive supplier with samples of the GreenStuf
products you are installing and the specification of the substrates you are
installing to. It is the installer’s responsibility to ensure that any
adhesive is fit for the intended purpose. It also is the installer’s
responsibility to ensure that the substrate is fit for the application of
adhesives and GreenStuf product. For information regarding adhesive suppliers,
please contact your account manager.
Installation Tools
A typical installation will require:
- Appropriate access equipment to ensure safe working conditions are maintained
- Measuring and marking out tools
- Insulation fastening system (i.e. insulation anchors and associated equipment)
- Pointed SDS chisel bit and battery drill, or appropriate hot-knife to create insulation anchor penetrations
- Cutting board, straight edge and insulation knife/saw/cutter to assist in trimming GreenStuf AAB sheets
- Knife and/or scissors for cutting and fitting foil tape (if required)
Cutting GreenStuf® AAB™: Mechanical cutters such as a straight knife
cutting machine are ideal for cutting and trimming GreenStuf AAB. Insulation
knives and insulation saws can also be used to trim panels to size.
Heavy-duty snap-off blade knives are useful for cutting holes for services.
All cutting tools must be sharp to help ensure an easy, neat and tidy cut.
Always cut slightly oversize to ensure a tight friction fit.
Caution should be taken with all cutting tools and equipment. Follow the
manufacturer’s use and safety instructions, as well as site and individual
safe working practices and requirements.
Installation: GreenStuf AAB should always be installed in accordance with
these installation instructions and as per the specification detail and
customer requirements. If there is conflicting information, you must seek
clarification from all appropriate parties before proceeding with the work.
It is important that the installation is planned before cutting and installing
any product. GreenStuf AAB sheets are supplied as standard 1200 mm (+20/-0 mm)
x 2400 mm (+100/-0 mm). We recommend all panels are checked prior to
installation. We recommend you “measure twice and cut once”.
Prior to installation, verify that the weight of the GreenStuf AAB to be
installed does not exceed the maximum allowable loading of the substrate or
ceiling system that the insulation will be fixed to or laid over.
Acoustic Absorber
GreenStuf AAB should ideally be installed with the textured or patterned
surface exposed to the room or space.
GreenStuf AAB can be fixed with insulation type fasteners. Fixings should be
set out at no more than 600 mm centres. Each fixing should be a minimum 100 mm
and a maximum of 200 mm from the edge of each panel.
The fastener length must be equal to the total thickness of the GreenStuf AAB
insulation panels to avoid compression and pillowing of the insulation sheet.
We recommend 11 fixings per standard panel (Fig. 1).
Fixing layout may vary depending on substrate. When fixing GreenStuf AAB to
the underside of corrugated/profiled steel floor composite systems, fixings
must be installed securely against the trough of the corrugation.
For installation speed and efficiency, we recommend that
the panels are installed in staggered formation (Fig. 2).
Checks should be made as the install progresses and panels are trimmed to
ensure a square tidy finish is maintained.
GreenStuf AAB should be installed touching the slab/substrate, but not
compressed. Any uncontrolled airspace between the GreenStuf AAB and the
slab/substrate may affect the installed thermal and acoustic performance.
GreenStuf AAB should
be installed tight to adjoining sheets and surfaces to ensure no gaps. Do not
compress the insulation as this will affect the thermal and acoustic
performance. The soft nature of GreenStuf AAB will allow some compression and
‘give’ when butt joining or finishing to adjoining surfaces. However,
GreenStuf AAB should be installed without visible folds and compression lines
in the finish.
GreenStuf AAB should be installed with all panels joining ‘width to width’ and
‘length to length’ to avoid colour variation in the install.
Prepare the first sheet for installation by creating penetrations for the
insulation anchors, taking account of fixing locations in the substrate.
Install the GreenStuf AAB panel by fixing from one corner then across the
width of the panel, and then down the length of the panel to ensure tight flat
install. Prepare and install successive panels with tight neat joins to
adjoining panels and surfaces until the install is complete.
Insulate all areas of the slab/substrate (as detailed on the plans and project
specifications) leaving no gaps.
When installed behind perforated or slotted panels, ensure GreenStuf AAB lays
flat and all perforations or open areas are covered.
Metal Roof: Where GreenStuf is to be installed beneath a roof, it is
essential that a minimum 25 mm air gap is maintained between the roofing
underlay and the GreenStuf AAB.
Infill Insulation: GreenStuf AAB can be used as an infill in both metal
and timber-framed partitions. GreenStuf AAB should be installed with no gaps.
Where required, drops should be mechanically fixed at the top to secure in
place until the substrate linings are installed. Low density roll options of
GreenStuf AAB can be torn by hand across the width of the rolls to achieve the
desired length.
Completion: Leave work secure, smooth and free of wrinkles, gaps, stains
and blemishes and to the standard required by following procedures.
Remove waste and recycle wherever possible. Leave site clean and tidy.
Service: For more information and installation support, please contact
your account manager.
Other Trades: Prior to installation, consultation with other trades such
as HVAC, plumbing and electrical should be made to ensure an order of works
that best suits the site is established.
