1 CI/SfB (47) Nf9 Uniclass JH61 October 2008 PACKAGING Tegral ThrutonePlus slates are delivered covered with a cardboard hood and polythene shrink-wrap on timber pallets. Slates are strapped in bundles of 15. STORAGE ThrutonePlus slates must never be allowed to become wet while stacked prior to fixing. They should be stored indoors or under cover and in all original factory packaging, to provide temporary protection until they are to be used. If outside storage is unavoidable, it must be for a short period only, in which case remove all original packaging and divide up the bundles within each pallet, leaving small gaps between them. This will allow air to circulate, avoiding the risk of efflorescence staining. Stack off the ground and cover with a well-secured good tarpaulin. SITE WORKING ThrutonePlus slates are designed so that fixing is relatively easy. However, as with all double-lap slating, it is important that the methods set out in Tegral s Slating Manual and in the Irish and British Codes of Practice are followed to ensure a neat and weatherproof roof. Where it is essential to cut ThrutonePlus slates, they can be scored and snapped over a straight edge. Remove cement dust to prevent unsightly staining of slates on courses below. TREATMENT OF LEAD Patination oil should be applied immediately to all lead surfaces to reduce the possibility of staining of ThrutonePlus slates. EXPOSURE TO WIND-DRIVEN RAIN The exposure rating of the site should be estimated from the Tegral Slating Manual or from Codes of Practice. Account should be taken of the local landscape, hill or coastal factors and the particular features of the building. Please contact Tegral s Technical Support Department for further information. MANUFACTURE Tegral ThrutonePlus slates are manufactured to EN 492: 1994 Class B, which is the highest classification attainable. We are Ireland's only manufacturer of fibre-cement slates. We do not produce slates for anyone else. DENSITY ThrutonePlus slates have a minimum density of 1750kg /m 3. FIRE The slates are designated Class 0 for Part B of the Building Regulations, meaning their usage on roofs and walls is unrestricted.

If during the period of guarantee the product is found not to conform to the stated properties in the standard, when sampled in accordance with ISO 390, the affected slates will be replaced at no cost. THRUTONE COLOURISATION The Thrutone colourisation system is a multi-stage process, incorporating water-based coatings and ensuring a highly durable surface finish. COLOUR GUARANTEE Tegral Building Products Ltd guarantee the Thrutone colourisation system for a period of 20 years. The slates will be affected by weather as described below and will take on a more matt appearance over time. However, when the roof is viewed from a reasonable distance, the slates will continue to show their generic colour appearance. If ThrutonePlus slates fail to give their generic colour appearance within the 20-year period, then an on-site treatment to the affected area(s) will be applied free of charge. This guarantee does not affect consumers' statutory rights. WEATHERING On exposure the slate surface and/or its coating will be affected by weathering which may vary with site location, aspect, pitch of roof and duration of exposure. Any deterioration in this respect shall not detract from the mechanical and physical characteristics as specified in the standard or from the function of the slate as a durable element year colour guarantee 20 year colour guarantee Be Proud of What You Build Available from Cert.

5 A Fixing ThrutonePlus Slates This page shows the fixing of the eaves, verge, ridge, open valley and hip of a standard roof with ThrutonePlus slates. ThrutonePlus slates are fixed with two 30mm x 2.65mm copper nails and a copper campion. They should never be nailed too tightly, with a 4mm gap left between adjoining slates. Definition of Standard Roof Any roof slope equal to or greater than the minimum pitch for the size of slate preferred that has a rafter length (horizontal projection - ie, measured on plan, not along the slope, from ridge to eaves) not exceeding 6 metres. For non-standard and special roofs contact Technical Support Department. (see accessory page). Two fixings must be used per ridge, positioned 100mm from each end. It is important that the cappings are predrilled with holes 2mm oversize. Do not over-fix the drive screws in order to prevent fracturing the capping. End units should always be full-length. E. HIP In order for correct hip construction, the points below are important: Underlay should be carried across the adjoining slope by not less than 150mm. Roll out an additional strip of underlay, not less than 600mm wide along the line of the hip from eaves to ridge. ThrutonePlus double-width slates should be used to prevent the use of small pieces of slate. Fix double-width slates with three nails and two crampions. Ridge cappings must be fixed with the internal socket facing up the slope. For advice on hip capping screws or drivescrews, see item C on page 8. A. STANDARD EAVES The eaves handles the greatest volume of water of any part of the roof. Great care needs to be taken when detailing and slating in this area. Below are some pointers to achieving good practice in slating this part of the roof: A tilting fillet should always be used, falling towards the gutter at an angle of approximately 10 degrees. This can be achieved using either a continuous timber piece, board material or Tegral underlay support tray. Where underlay is not resistant to UV degradation, an eaves reinforcement strip of durable, UV-light resistant material, such as a Type 5U felt or Tegral underlay support tray should be installed. The eaves consists of cut first and second undereaves slates; the lengths of these slates are equal to the batten gauge and the batten gauge plus headlap respectively. B. STANDARD DRY-FIXED VERGE As the roof verge is often subject to unusual, spiralling turbulence, it is important to ensure that the edge slates are adequately secured. Verges are finished using a dry, non-mortar system. The following should be observed on the verge detail: Underlay should carry out over the wall and extend approximately 20mm beyond the bargeboard. Start alternate courses with a cut slate or cut double-width slate ensuring that no slate is less than 150mm wide. Fix double-width slates with three nails and two crampions. Secure cut slates with Tegral trim or drill and tie with copper wire to the slate below. Battens should overlap the wall and where the verge is overhanging, be supported on a flying rafter. C. STANDARD DRY-FIXED RIDGE Tegral ThrutonePlus slates are capped with smooth fibre-cement ridges in a complementary or contrasting colour. As the ridge is the most exposed part of the roof, it must be securely fixed and should form a good seal at the apex. Good and secure fixing can be achieved as follows: Underlay should overlap the underlay on the other slope by not less than 225mm. Increase headlap (never decrease) on the final few courses to achieve a neat and uniform finish. It is vital to the weatherproofing of the roof that the specified minimum headlap be provided in the vicinity of the ridge. Fix additional battens at the top to facilitate fixing. The internal socket should face towards the prevailing wind. Fix using 50mm x 10 gauge brass or stain- D. OPEN VALLEY After the eaves, the valley receives most of the water from the roof. The following should be carefully considered when constructing a valley: The open width of the valley should be 125mm minimum. The valley boards should extend not less than 225mm each side of the centre of the valley. The top of the tilting fillet on each side should be level with the tops of the battens. The top of the tilting fillets should be 150mm from the centre of the valley, measured along the slope. ThrutonePlus double-width slates should be used to prevent the use of small pieces of slate. Fix double-width slates with three nails and one crampion. Each length of lead should not exceed 1500mm. Add an extra wide batten to either side of the hip to accept the fixings for the hip cappings and as added support for the cut slates.
