Thermal Soffit Liner must be handled with care. Transport and store Thermal
Soffit Liner on a flat, clean and dry surface. Avoid abrasion, delamination or
distortion and protect edges from being crushed. Avoid harsh rubbing, bending
panels and do not drop panels on their corners as this can cause damage to the
panel. The work area should be clean and tidy and free from dirt and
contaminants that could soil the panels. Do not accept damaged product. If
product or packaging arrives damaged ensure you note the condition on the
freight documents and contact GreenStuf immediately. Goods signed as receipted
in ‘good condition’ will not be the responsibility of GreenStuf.
Inspection
Before starting the installation, check again that the 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.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.
CAUTION: Electric cables and equipment partially or completely 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 3000:2018 Wiring Rules. Ensure you understand your responsibility before you begin the installation.
Lights and Electrical Appliances
Regardless of the type of thermal 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 manufacturer. If in doubt,
leave a clear 50mm space between the fitting/appliance and the edge of the
insulation. Refer to a registered electrician for further guidance.GreenStuf®
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
Downlights Factsheet.
Product Format
Thermal Soffit Liner is supplied as standard 1200mm (+5/-0mm) x 2400mm
(+10/-0mm) sheets in Flint (light grey) colour. Custom sizes and colours may
be available on request but are subject to minimum order quantities. Thermal
Soffit Liner is non-woven and 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.
Insulation Fasteners
Thermal Soffit Liner is intended to 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 Thermal Soffit Liner
insulation panels to avoid compression and pillowing of the insulation sheet.
Use fixings in accordance with the manufacturer’s technical information and
instructions.
Adhesives
In certain applications, Thermal Soffit Liner can be direct fixed using
adhesives. GreenStuf recommends a contact-type adhesive or full curing panel
adhesive for applying Thermal Soffit Liner 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 GreenStuf
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 Thermal Soffit Liner sheets
- Knife and/or scissors for cutting and fitting foil tape (if required)
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 Thermal Soffit Liner 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.
Cutting Thermal Soffit Liner
Mechanical cutters such as a straight knife cutting machine are ideal for cutting and trimming Thermal Soffit Liner. 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.
Clearances
Cut Thermal Soffit Liner 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.
Installation
GreenStuf® ASL 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. Thermal Soffit Liner sheets are supplied as standard 1200mm (+5/-0mm) x 2400mm (+10/-0mm). We recommend all panels are checked prior to installation. We recommend you “measure twice and cut once”. Thermal Soffit Liner is generally fixed with insulation-type fasteners. Fixings should be set out at no more than 600mm centers. Each fixing should be a minimum 100mm and a maximum of 200mm from the edge of each panel. The fastener length must be equal to the total thickness of the Thermal Soffit Liner 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 the substrate. When fixing Thermal Soffit Liner 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 a staggered formation (Fig. 2). Checks should be made as the installation progresses and panels are trimmed to ensure a square tidy finish is maintained.
Thermal Soffit Liner should be installed touching the slab/substrate, but not compressed. Any uncontrolled airspace between the Thermal Soffit Liner and the slab/substrate may affect the installed thermal performance. Thermal Soffit Liner should be installed tight to adjoining sheets and surfaces to ensure no gaps. Do not compress the insulation as this will affect the thermal performance. The soft nature of Thermal Soffit Liner will allow some compression and ‘give’ when butt joining or finishing to adjoining surfaces. However, Thermal Soffit Liner should be installed without visible folds and compression lines in the finish. Thermal Soffit Liner should be installed with all panels joining ‘width to width’ and ‘length to length’ to avoid color variation in the installation. Prepare the first sheet for installation by creating penetrations for the insulation anchors, taking into account fixing locations in the substrate. Install the Thermal Soffit Liner 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 installation. Prepare and install successive panels with tight neat joins to adjoining panels and surfaces until the installation is complete. Insulate all areas of the slab (as detailed on the plans and project specifications) leaving no gaps.
E-Foil – Tape Joins
When using Thermal Soffit Liner with E-Foil, a 50mm wide foil tape can be used
to seal the panel joins and any penetrations. Refer to the tape manufacturer’s
instructions regarding climatic conditions and suitability of use. Ensure
surfaces are free of dust, dirt and oils. A suitable tape should be applied
over the centre of the join and pressed firmly to the Thermal Soffit Liner
E-Foil facing. Please make sure the tape does not stretch as this can create
buckles and voids in the contact area. The tape should be wiped firmly to
ensure adequate adhesion to all surfaces. Cut and fit the tape with a knife or
scissors as required.
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 the site clean and tidy.
