However, the safety strips do not increase the load bearing capacity in the serviceable range of the corrugated sheet.
MINIMUM ROOF PITCH ESAL Profile 5 can be laid on constructions where the roof pitch is min. 7°. Consideration should also be given to the lenght of the roof and exposure of the site. Where slopes are between 7° and 10°, the end lap should be sealed with a mastic ribbon (polyisobutylene based material), which has a rubby, tacky consistency. End lap of corrugated sheets ESAL Profile 5 is minimum 20 cm. Where severe weather conditions are expected the end lap should be increased (up to max. 30 cm) and end lap should be sealed up to 15°. For additional protection against wind driven snow or rain as well as against stagnant water on the roof (especially along the eave) during snow melting, double skin roofing with ventilation is advised.

Moulded goods, where the direction of lay on duo pitch roofs can start both slopes from the same end of the building (if not used in combination with the first ones) or for right to-left direction of lay as shown in the picture, are: - universal ridge piece Anhovo - angular ridge piece.
Direc tion of la y
Sheets are usually laid in upright rows from right-to-left, when looking from floor to ridge. Minimum end lap of sheet is 20 cm, side lap is 47 mm or 1/4 of corrugation. Installation will be correct and successful, if, by means of a string line, the estimated position of the sheet will be drawn before the work on the roof begins.
50
The upper edge of the lower sheet must be set aside over the upper edge of the purlin for 50 mm.
MITRING To avoid four thickness of sheeting at the junction of side and end laps, it is necessary for two of the sheets at each junction to be mitred at the corners so that they lie in the same plane.

PURLIN SP ACING SPA Corrugated sheets are installed and fixed on wood or metal subconstruction. For usual roof structures with rafters at distance 80 to 100 cm battens 6 x 6 cm are used. When longer sheets are used, which are installed over three purlins, the intermediate purlin must be higher than the rest of the purlins for 5 mm.

For end lap of the sheet 20 cm. With purlin spacing 1150 mm, the superimposed load on the sheet should be maximum 3,4 kN/ m2; while with purlin spacing 1400 mm the load shoud be maximum 2,36 kN/m2. In all other cases, purlin spacing should be determined by statical calculation.
STRING LINE Before installation, the string line should be drawn on the roof structure. Drawing is preformed by means of a string, dyed in dry colour powder.

First, the perpendicular line is drawn on the roof, precisely, on the right side. Right-to-left direction of lay is taken into consideration. The width of the first string line is usaully equal to the width of the whole sheet, i.e. 920 mm , while other lines equal to useful width of the sheet, i.e. 873 mm. The imaginary starting line depends of the gable detail.
rtin g
The last sheet on the other gable side is cut for 90 mm in order to make the roofing finish with net corrugation. It should be noted that if the string line does not correspond to the size of the whole sheet, the sheet should have at least three corrugations.

Number of horizontal rows according to the lenght of the roof from eave to ridge The number of horizontal rows needed is calculated according to the useful lenght of the sheet. When roofing with sheets of various lenghts, the longer sheets are used at the eave and the shorter ones at the ridge. Useful lenght of the sheet = lenght of the sheet – end lap

FIXING The selection of correct sheet fastner is extremly important. Self-drilling and self tapping fasteners are generally used to fix ESAL Profile 5 sheets to purlins. These fasteners drill through ESAL Profile 5 sheet, creating a 2 mm oversize hole and self tap into the purlin. It is important that the fasteners are installed using correct power tools, which should have an adjustable depth setting device to ensure the washers are seated correctly not too loose or too tight. The fasteners have different drill points to suit the following purlin types. The fasteners are always driven perpendicular into the corrugated sheet surface, at least 50 mm from the sheet edge. Normaly two screws per sheet in end lap purlin are required. The correct position of the screw is on the top of the 2nd and 5th corrugation of the sheet. Each sheet is fixed with at least four screws. The number of fasteners increase in case of high buildings, tower-like buildings or on exposed areas. For additional information, please, do not hesitate to call our Technical Service.

UNIVERSAL RIDGE PIECE ANHO VO ANHOV Universal ridge piece Anhovo can be used for roof pitches from 20° to 30°. Ridge piece Anhovo has 6 corrugations and the side lap is one corrugation. Mitre cut is not necessary at the ridge. The ridge piece is fixed on the ridge batten on the 2 nd and 5th corrugation of the ridge piece, using the same fasteners as for fixing sheets. Ridge batten is 5 cm wide. Its height depends on the height of purlins on the roof and roof pitch. For example: If the roof pitch is 20° and the height of the purlins is 6 cm, the height of the ridge batten is 11,5 cm. Ridge piece Anhovo should be laid on the sheet corrugation along the ridge.

SNOW PROTECTION Snow protection pieces are evenly placed on the roof surface. The first row of snow protection pieces at eaves should be more dense; or the line snow protection should be installed at eaves. Local regulations should be taken into consideration. The number of snow protection pieces ESAL depends on the roof pitch and the estimated snow load; it is given in detail in the accompanying table.

PRO TECTION A T WORK PROTECTION AT The provisions of the local Rules on safety requirements for construction work, work at height regulations and all other technical regulations and rules should be followed. Roof work should be carried out by professionally qualified workers, healthy for work at height. If the sheets are humid or wet, special precautions should be made as there is a danger of a fall from the roof. Also, sheets must be fixed simultaneously not to get lifted and damaged by the wind.
HANDLING WITH MA TERIAL MATERIAL During transport and when stored at site, fibre-cement sheets should be kept save from mechanical damages, sun and rain. The supplier’s original foil protecting the stacks is not sufficient. Corrugated sheets should be kept in dry and covered areas. Temporarily, sheets can be stored outside but they should be covered. It is necessary to enable ventilation for stacks under the coverage; otherwise condensation of moisture would appear. This leads to excretion of free lime, usually present in the material, which creates white spots on the surface of sheets. White spots on the sheets do not have negative influence on the characteristics of material, however, they spoil the aesthetic outlook of sheets. It is absolutely forbidden to allow water between the sheets in the stack.
Fibre-cement is natural material which combines good characteristics of sheets such as water impermeability and vapour permeability. Due to these characteristics, when new corrugated sheets are installed on the roof, moisture spots may appear on the underside of sheets, which have no negative influence on the serviceability of the roof. After a period, this phenomeon disappears. This is a well known temporary phenomenon and will disappear. It in no way affects the waterproof quality of the sheets.
TOOLS During work, electric tools either not forming fine dust or simunltaneously pumping it should be used. Tools with high speed or high number of revolutions should be avoided.
When fixing sheets with self-drilling fasteners, relevant electric machine should be used as SFS Spedec CF 40 with depth locator to prevent under or over tightening, which can damage the roof sheets.
Sheets can be worked on also by means of hand tools as for example the fox tail saw (distance between teeth 5 mm), joiner’s rasp, screw-key and tongs with the blade made of hard metal ( carbide) on the handle.
To draw the string line, a string and dry colour in powder is needed.

Sheets should be lifted off the stack, not dragged.
