5. A durable notice in accordance with BCA requirements (Clause B1.4 (i)(ii) Volume 1 and part 3.1.3.2 (b), volume 2 is attached to the building which states that the Termiglass barrier is installed. Notes: This notice should mention that the barrier should not be breached by tree roots, non-termite resistant material, or contaminated or disturbed by other means.
6. When used in conjunction with other termite barriers, all treatment is to comply with the requirements of AS 3660.1-2000 ‘Termite management-New building work’.
7. There is no plant matter or building refuse where the Termiglass is to be placed.
Notes:
(i) As a guide the species mastotermes darwiniensis are believed to be located north of the Tropic of Capricorn.
(ii) At the time of the Appraisal testing is being undertaken of the effectiveness of the barrier systems against mastotermes darwiniensis.
The results of this testing will be reviewed with the possibility of removing this restriction during the term of validity of this appraisal.

Cavity treatment Condition:
Termiglass is used internally at the base of perimeter wall cavities and where the adjoining external masonry wall is not termite resistant, termite strip shielding is incorporated into that masonry and is folded vertically such that it penetrates into the Termiglass to a depth of not less than 35mm.

Concrete slab penetrations Conditions:
1. All penetrations are collared with not less than 25mm width x 75mm depth of compacted Termiglass and capped with Termiglass capping compound.
2. Penetrations passing through perimeter Termiglass barriers are encased in not less than 25mm of Termiglass.

Construction Joints Conditions:
1. The Termiglass is contained within a smooth sided ‘void’ positioned at the joint or groove.
2. The compacted dimension of Termiglass shall be not less than 75mm in depth and 25mm in width.
3. Where exposed, the Termiglass shall be capped or sealed with Termiglass capping compound.
4. The Termiglass must extend for the full length of the joint and interface with the perimeter barrier at the ends
Notes:
(i) The Building Code of Australia draws attention to the need for regular inspections.
(ii) Installation of any type of termite barrier cannot guarantee a 100% protection against infestation by subterranean termites. Thus, the installation of physical barrier does not negate the need for regular competent inspections. Any additions, alterations or earth works, including gardening adjacent to the building, may render the barrier ineffective. Such activity should be referred to a licensed installation contractor for appropriate advice and treatment.

RELEVANT DOCUMENTS
Termiglass Installation Manual, November 2003 Standards Australia, AS 3660-2000, ‘Termite management Part 1. New building work’.

APPROVED ASSESSMENT EXTRACT
The Termiglass System as distributed by Termicide Pty Ltd ABN 18 003 608 018 and its licensees and installed by installers trained and approved by Termicide Pty Ltd will satisfy the requirements of AS 3660.1-2000 ‘Termite management-New building work’ as a suitable physical barrier against subterranean termite entry when the conditions of CSIRO Appraisals Technical Assessment 313 are fulfilled.

APPRAISAL DESCRIPTION
The following description is based on information provided by the applicant. General: Termiglass is graded glass screenings used as a termite barrier. The glass material ranges in size from 1.2mm to 3mm. The screening system ensures that each particle of glass is graded to precise specifications for size, shape and composition. Termiglass particles are too large and heavy for termites to carry, too hard for termites to chew and the spaces between the particles are too small for termites to crawl through. Installation: Termiglass can be used as a physical barrier to protect against subterranean termite attack in the following cases: In general,
• Where used in the cavity of a double brick wall or brick veneer wall on a raft, formed void or infill (footing) slab, the Termiglass barrier is to be not less that 40mm wide and to extend not less than 75mm above the adjoining finished ground level. The compacted depth of the Termiglass is to be not less than 75mm.
• Non compacted Termiglass provides protection to under suspended timber floors. All timber stumps, poles and supports are to be individually protected.
• All slab penetrations are surrounded by an enclosed, compacted collar of Termiglass measuring not less than 75mm in depth and 25mm in width. The Termiglass that ‘collars’ the penetration must be retained from beneath and capped or sealed on top with Termiglass capping compound.
• When used on construction joints Termiglass is placed in a smooth sided void and compacted to a depth of not less than 75mm and width of not less than 25mm. Where the void is within or on top of the joint or groove, the bottom of the void is sealed to prevent the Termiglass escaping through it. If exposed, the top of the Termiglass is sealed as for penetrations. Alternatively, the same dimensions of Termiglass can be contained within a durable termite resistant basket arrangement that is cast into the underside of the slab. The basket arrangement must allow for independent movement of the two slab sections without breaking the integrity of the Termiglass.
• Termiglass can also be used as a physical termite barrier to protect around typical services and connections and waste trap installations. It is installed by licensed installation contractors approved by Termicide Pty Ltd and in accordance with the relevant installation instructions and specifications for the particular use. • Termiglass can also be used as a termite barrier at construction joints.
• Installation guidelines are supplied on request to assist in the planning and design. The installer will supply a ‘Treatment Certificate’ with each installation. Components: Termiglass is graded glass screenings. Particles range in size generally between 1.2mm and 3mm. Termite Quikstrip Strip Shielding. Termiglass Quickstrip strip shielding used in conjunction with Termiglass must be in accordance with AS 3660.1-2000. Materials recommended by the applicant and used/assessed in this appraisal include
• Unplasticised polyvinyl chloride extrusion formulation consisting of not less than 80% PVC and 10% titanium dioxide conforming to AS/NZS 1260:1999, ‘PVC pipes for fitting for drain, waste and vent applications’.
• Aluminum that is manufactured from Marine Grade aluminum not less than 0.5mm thick. It is joined using Termite Resistant Silicone. Where necessary, the material may be lapped and jointed for at least 30mm to produce a termite resistant joint using a solvent or termite resistant silicone sealant.

DESIGN INFORMATION
General: Based on information from the applicant, Termiglass is a physical termite barrier to protect against subterranean termite attack. It consists of graded glass screenings. Termiglass can be used with suspended floors, concrete slab on ground, and around typical service penetrations and connections and waste trap installations. It is installed by installers approved by Termicide Pty Ltd in accordance with the relevant installation instructions and specifications for the particular use, as described in the Termiglass Installation Manual. Durability: In the opinion of CSIRO Appraisals, the life expectancy of the system would be not less than 60 years provided that the barrier is installed in accordance with the requirements of this appraisal and is not breached by tree roots, contaminated or disturbed by other means Maintenance: An annual inspection is made of the building to check for bridging or breaching of the barrier. With consultation with the owner, the installer carries out this inspection. If bridging or breaching is found, suitable rectification must take place.

Paul G Bailey CSIRO Appraisals

CSIRO Appraisals is a project of CSIRO Manufacturing and Infrastructure Technology providing a range of assessment products including:
• Technical Assessments – full fitness for purpose appraisals of innovative products, systems or materials that may or may not be covered by Australian Standards or building regulations.
• Interim Reports – appraisals of products that have not yet reached the fully developed or manufacturing phase. They aid with product development and may be used as a step towards a subsequent Technical Assessment.
• Certification Assessments – appraisals of products, systems or materials solely against the requirements of the BCA and used for gaining approval from Federal or State authorities.

From 1978, under the auspices of the Australian Building Systems Appraisal Council (ABSAC), CSIRO ran an appraisal service in conjunction with the Australian Institute of Building Surveyors, the Housing Industry Association, the Insurance Council of Australia and the Master Builders Association. In 1999, CSIRO Appraisals was formed to continue the business of ABSAC under the sole patronage of CSIRO. This new scheme retains the committee structure of technical and interstate advisers that operated as ABSAC. All past ABSAC publications and appraisals are being continued and supported by CSIRO Appraisals.

CSIRO Appraisals is a founding member of the World Federation of Technical Assessment Organizations

Technical Assessments are intended to help all those concerned with the approval, specification and use of new products or systems. They are objective assessments of the fitness for purpose of the product, system or material but are not approvals or endorsements. They may be submitted to approval authorities as part of the justification process required to obtain approval.

Each Technical Assessment has been prepared by CSIRO Appraisals and then reviewed, revised and finally endorsed by the Technical Advisory Committee (TAC), detailed below. CSIRO makes the appraisals on a national basis by obtaining input from regional committees in each State and Territory to take account of variations in local building regulations, practice and local climatic features.

CSIRO Appraisals bases its assessment on the product and information it receives and cannot accept responsibility for deviations in the manufactured quality and performance of the material, product or system. However, Technical Assessments will be withdrawn where adequate quality or performance has not been maintained.

Technical Assessments are given a term of validity of three years from the date of issue. They are reviewed annually and at the end of the term of validity may be extended for a subsequent three-year term. The validity of a particular Technical Assessment can be obtained from CSIRO Appraisals. A Technical Assessment must not be copied, in whole or in part, without authorisation by CSIRO Appraisals.
