Introduction;

AthyECOSlate is an Environmentally Friendly Product that uses a specific recycled plastic as base

material. AthyECOSlate will not crack or break and so can be fitted much quicker than other types of

roofing tiles and roof slates.

As it's much lighter than normal roof tiles and consequently needs less supports. It is also durable,

low cost and requires no maintenance as it will not crack, lift, break or warp. They do not contain

any natural minerals, asphalt or cement and do not encourage the growth of algae and moss.

AthyECOSlate can be walked on without cracking, is an impact resistant roof slate that is low cost

and requires no maintenance.

The fastenings may be suitably plated or coated to achieve the necessary durability or compatibility, or both. NOTES: 1 In highly corrosive areas, fastenings should be manufactured from and coated with materials that ensure resistance to the increased risks of corrosion these areas present. See AS 3700 for classification of corrosive areas. 2 AS 1562.1 provides details for protection against corrosion and acceptability of direct contact between metals or alloys

Installation

SARKING

General Sarking shall be provided for all roofs where the design wind classification category is greater than N3. Where required, pliable and reflective-foil sarking shall be installed in accordance with AS 4200.2.

7

Where rigid or semi-rigid material is used as sarking, it shall be installed to provide adequate means for the water to discharge to the eaves. NOTE: Sarking may also be necessary in other circumstances depending on roof pitch, length of rafter, fire hazard or tile type.

Anti-ponding device/board

An anti-ponding device/board shall be provided as follows: (a) On sarked roofs with pitches of less than 20°. (b) On all roof pitches where there are no eaves overhang.

Damage Care shall be taken to avoid damaging the sarking during installation or tile-installing operations. Any tears or punctures, other than those caused by the installation of fixings over rafters, shall be repaired with a purpose-made sarking tape.

Requirements for roofs without general sarking

Water shall not be discharged from a gutter/valley or downpipe on to tiled roofs, unless adequate provision is made to prevent inundation of the tiling or to conduct penetrated water away. Such provisions would include spreader pipes, flashing or sarking. The provision of spreader pipes or flashing shall be in accordance with AS/NZS 3500.3. Where sarking is used, it shall be a minimum width of 1800 mm, either side from the point of discharge, and extended down to the eaves gutter.

Long rafter lengths

Long rafter lengths may require sarking to prevent inundation of the roof. These lengths may vary according to the tile type, the pitch of the roof and the exposure. The manufacturer’s specifications should be consulted. Table 5 indicates maximum rafter lengths, measured from the topmost point of the rafter downwards, below which sarking shall be installed over the remainder of the rafter length.

BATTENS AND RAFTERS

General Battens shall be installed in accordance with AS 1684.2, AS 1684.3 or AS 1720.1, where appropriate, and the specific requirements of this Standard. At the eaves, the profile of the roof shall be maintained by the use of tilting battens, fascia boards, or other means.

➢ Batons must be 75x25mm pine for up to 600 centres and 75x37mm for up to 900 centres.

➢ All Batons are to be double nailed with 75mm nails and joints on 900 centres to be screwed with 75mm baton screws.

➢ Oregon 75x35 may also be used on 900centres

Batten alignment

Battens shall be aligned to within a tolerance of <>20 mm in 4 m.

Batten spacing

Battens shall be installed to the specified spacing tolerance. This tolerance shall not be greater than <>5 mm. Unless otherwise specified, the tile end-lap shall be not less than 75 mm.

Batten installation

Battens laid on the flat shall be fixed to every support with at least one nail or other mechanical installation. See Note 1. Battens laid on edge shall be secured by double fastening or be blocked. Battens in excess of 75 mm in height shall be blocked or otherwise restrained from overturning. Battens wider than 50 mm shall be secured with two fastenings to each rafter or truss.

Batten joins All batten joins shall be such that the structural integrity of the batten is maintained. All batten joins shall be at minimum, butt joined and staggered so that each grouping of three battens does not contain any more than one join on the one rafter, with the exception of steel battens which may be lapped over the same rafter or joined between rafters using a mechanical joiner designed to comply with AS/NZS 1170.1 and NASH Standard for Residential and Low-rise Steel Framing, Part 1: Design Criteria. NOTE: Batten joins would normally be over the centre of a rafter. For high wind and cyclone areas, where the timber batten is unable to be joined over a rafter, individual engineering design and certification, or other published documentation that is deemed to comply under the Building Code of Australia, will need to be used. Battens shall not be joined on a multi-ply truss or a girder truss. NOTE: A girder truss is a truss, with one or more brackets attached, that supports adjoining trusses. Battens shall not be joined in the area formed by a gable end and the steel brace.

Slate tiles

General All tiles shall be aligned vertically and horizontally.

Sarked roofs Where the roof is fully sarked in accordance with AS 2050 Clause 3.1, the wind classification in as above may be reduced one class for the purposes of Tables 4(A) and 4(B) of AS 2050 NOTE: AS 2050 Tables 4(A) and 4(B) are based on AS 4055, modified for terrain and height.

Set out Tiles must be laid out in a triple lap system strictly sticking to the gauge. DO NOT EXCEED THE GUAGE FOR ANY REASON. The skates must overhang fascia by a minimum of 50mm. The slates must also be kept in a horizontal line by the small half mark at the top of the slate (when laying this mark must always be visible).

Fixing All slates must be fixed with two ring shank nails. This includes hip, Short course and valley cuts.

Spacing The slates are spaced by two V shaped spacers on the top side of all slates.

Valleys All slates must be cut into valleys lapping at least 100mm with a gap to let leaves and debris escape. (DO NOT MORTAR SEAL OVER VALLEY CUTS) NOTE: Where practicable, valley cuts should be secured to the tile batten. Small valley cuts should be secured by valley clips or similar means.

Flashing Step flashing is to be used when slates terminate at a wall. The flashing may be any material approved for use under the building code and remains the responsibility of the installers. Each flashing 220mm in length is to be installed on top of the first slate and under the second slate so you cannot see the flashing on the slate. This process is repeated all the way along the ridge.

Gable tiles All starters, finishers, and full tiles at the end of each course at a gable shall be

11

mechanically fastened. Flexible pointing shall not be used as the sole means of mechanical fastening. Flexible pointing shall be used in conjunction with either nails, screws, or clips. On unlined projecting gables, every tile in the overhanging portion shall be mechanically fastened.

Eaves tiles Eaves tiles shall overhang the fascia or tilting batten by an amount sufficient— (a) to ensure that water discharges into the gutter; and (b) to permit replacement of the gutter. NOTE: This will usually mean an overhang of 50 <>15 mm. Where no eaves gutter is provided, every eaves tile shall be mechanically installed in accordance with the appropriate loading requirements.

Hips Provision shall be made to align tiles and part tiles at hips to ensure that they are in the same plane as adjacent tiling.

Ridging All ridging shall be laid so to achieve a straight and regular line of ridge tiles. All ridges are to be bent to shape of the roof by gently heating with a heat gun and fixing on each side with a relevant length ring shank nail. Ridges must not exceed 180mm on the show face. If fixing colour bond roll top ridge, all courses must be screwed on each lap (20mm up to the ridge face and 20mm in ridge face an on top ridge in the centre of each slate with 50mm coloured teck screws with rubber washers.

Barge capping tiles

All barge capping tiles shall be mechanically fastened. Screw fixing is recommended

Cut tiles in cyclonic regions

Cut tiles installed in wind classification C1-C3 [Table 4(B)] at ridges and hips shall be supported in the same plane as adjacent tiling and secured. NOTE: Where practicable, valley cuts should be secured to the tile batten. Small valley cuts should be secured by valley clips or similar means.

BEDDING AND POINTING

Bedding and pointing may be used to hold down, align, weatherproof, infill and decorate the verge, eaves and junction of tiles and accessories. Where bedding and pointing is used, all mortar used shall be in accordance with Clause 2.3 of AS 2050. NOTES: 1 Ridge tiles and fittings may be laid without bedding or pointing provided they can be adequately installed by other means [see Tables 4(A) and 4(B) of AS 2050. 2 Bedding and pointing applied to tiles may require the formation of weep holes to permit drainage. 3 Structural movements may result in the cracking of bedding and pointing

TILING OVER SEPARATING WALLS

When tiling over separating walls, only roof battens, non-combustible pliable building membranes and sarking materials may pass over the separating wall. The maximum batten size shall be 50 mm × 75 mm. The space between tile and wall shall be filled with non-combustible fire-stopping material that complies with the requirements of the Building Code of Australia. Mortar shall not be used to fill this space.

12

WORKMANSHIP The cutting of tiles at ridges, hips, verges and valleys shall be neat and shall present a straight line. Tiles at ridges and hips shall extend under the capping by a sufficient distance to be weatherproof. Similarly, tiles shall overlap valleys by a sufficient distance to be weatherproof. Cut tiles at ridges and hips shall be supported in the same plane as adjacent tiling and secured. See Note 4. The bedding and pointing shall be weatherproof. NOTES: 1 The pointing should be regular in appearance and should have uniform colour and texture. 2 For durability purposes, the pointing should be trowelled off to provide a neat appearance. 3 Due to the composition of flexible pointing, some minor surface imperfections are acceptable. 4 Valley cuts should be secured to the tile batten where practical. Small valley cuts should be secured by valley clips or similar.
