Be careful not to dam any valleys or pans so that rainwater can drain freely from the high side of the roof penetration Moisture held in such areas can cause deterioration of the sheet coating reduced life expectancy or poor appearance Where damming of any valley or tray is unavoidable due to the size of the pipe penetration treat the installation as a large penetration Section 11 5 Copper penetrations All copper pipe penetrations through ZINCALUME or COLORBONDS steel cladding must be physically and electrically isolated from the cladding This can be done by using a sleeve of PVC polythene or similar plastic that is also ultra violet stable Penetration between ribs Penetration between ribs Draw bandy z P a skirt Flanged f sleeve Roofing Clearance essential Sealant Small penetration Fasten oe Figure 11 6 1 Small penetration with metal skirt and sleeve Figure 11 6 2 Small penetration with sleeve Dektite sleeve illustrated 11 7 Flashing walls Cladding is usually installed with the profile running vertically or horizontally though sheets have been laid diagonally the choice is aesthetic Wind can drive rain hard against wall flashings so it is important that you pay attention to the detailing of flashings around windows doors re entrant and external corners to ensure you get a watertight building You also want a neat appearance We make wall f

Usually over fastener locations Be careful when moving between supports Do not walk in the pan immediately adjacent to flashings or translucent sheeting Walk at least one pan away Always take particular care when walking on wet or newly laid sheets particularly on steeply pitched roofs If there will be heavy foot traffic on a roof provide a temporary walkway or working platform with consideration of hand rails to minimise damage 7 5 Marking out cutting and drilling Marking out A pencil of any colour may be used except black or so called lead pencils Don t use black pencils to mark roofing or walling because the graphite content can create an electric cell when wet and thus cause deterioration of the finish You can also use a string line with chalk dust or a fine felt tipjped marker Cutting Where possible you should minimise site work by using sheets cut to length in the factory For cutting thin metal on site we recommend that you use a power saw with a metal cutting blade because it produces fewer damaging hot metal particles and leaves less resultant burr than does a carborundum disc Alternative cutting tools electric shears and nibblers are also suitable however extra care with the straightness of the cut may be required Cut materials over the ground and not over other materials where hot particles can fall and cause damage to finishes especially COLORBOND prepainted finishes It is best to

13. If the space left between the last full sheet and the fascia or parapet is more than a half sheet width a sheet can be cut longitudinally leaving the centre rib complete This partial sheet can be fully clipped onto a row of clips as for a full sheet before installing the capping or flashing If the space left between the last full sheet and the fascia or parapet is less than a half sheet width it can be covered by the capping or flashing In this case the last sheet should be secured by cutting sheet in halves and fastening the underlapping rib at each purlin with a half sheet Figures 9 1 22 amp 9 1 23 Similarly a half clip may also be used if required In this case where a partial sheet of less than two ribs is used it is necessary to turn up the lip along the edge of the cut sheet This can then be covered by the capping or flashing Figure 9 1 22 KLIP LOK 406 Placing last sheet where half a sheet will fit Figure 9 1 23 KLIP LOK 406 Placing last sheet where half a sheet won t fit EASYCLAD Installation 9 3 Installing EASYCLAD You can use EASYCLAD for walls soffit linings or ceilings Use a similar installation procedure for all EASYCLAD 2 pans per sheet are pierce fixed through the underlapping edge of each sheet The fasteners in one sheet are concealed by the leading edge of the next For the last sheet a trim channel is used If you are using EASYCLAD with the ribs horizontal start installing f

16. 12 Fully engage the two sheets along the overlapping rib You can do this by walking along the full length of the sheet with one foot in the centre pan of the previous sheet and the other foot applying vertical pressure to the top of the interlocking ribs at regular intervals It is recommended that you don t walk in the unsupported pan beside the underlapping rib Figure 9 1 13 With long spans additional care may be required to ensure the overlapping rib adequately engages onto the underlapping leg Care should be exercised due to the potential instability of the side lap when it is not adequately engaged interlocked 13 Similarly engage all the clips by applying vertical foot pressure to the top of the other two ribs over each clip It is essential that the sheets interlock completely It is important that your weight is fully on the sheet you are installing 14 Fit an S clip at the last rib of the profile similar to Step 9 when the sheet was started Both starting and finishing requires an S clip Check alignment occasionally Occasionally check that the sheets are still parallel with the first sheet by taking two measurements across the width of the fixed sheeting At about half way through the job perform a similar check but take the measurements from the finishing line to aim for the final sheet to be parallel with the end of the roof If the measurements are not close enough lay subsequent sheets very sligh

Flashing large roof penetrations Penetrations through ribbed cladding block the valleys or pans and thus affect the free flow of rainwater down a roof All flashings have to weatherproof the cladding but on the uphill side of large penetrations they also have to channel rainwater sideways into valleys that run unobstructed to the eaves Four methods are described here In all methods the ends of cut ribs may be closed off with caps on the outside of the rib or with plugs inside the ribs Plugs must be used on side laps to allow the anti capillary cavity to drain Note For masonry construction Building Code Australia BCA requires the use of Damp Proof Course DPC to ensure weatherproofing For acceptable methods see BCA section on weatherproofing masonry Support framing Wherever one or more of the sheet ribs are cut you must provide framing to support the cut ends of the roof cladding each side of the penetration Existing flashing If you have to re use lead flashings that are built into the structure special protection is needed Section 11 1 Method 1 Head gutter and apron flashings This is often the simplest method and commonly used for existing protrusions Figure 11 5 1 See also Fig 2 4 1 Flashing from TS Flashing at change of pitch Figure 11 4 1 Typical flashing at changes of pitch Head gutter positioned under sheet sealed and fastened to sheeting Support gutter amp ends of roofi
