About Shadowline™ 305

Fielders® Shadowline® 305 is a two pan, low-pitched roof deck that can be used down to a minimum of one degree pitch as a concealed fix button punched deck (see Figure SL IG NC 001) or as a pierced fix wall cladding. Fielders® Shadowline® 305 is available in all states of Australia except WA - see Shadowline® WA for details.

When used as a wall cladding Fielders® Shadowline® 305 can be fixed both horizontally and vertically through each pan to each girt with a hexagon head self-drilling and tapping screw. The exact specification is subject to project requirements.

Fielders® Shadowline® 305 can be rolled to any transportable length in ZINCALUME® with the full range of COLORBOND® colours in 0.70 BMT gauge.

Lead time for the Shadowline® 305 profile is subject to the material finish and the colour availability. Smaller quantities are available as a stock item, subject to normal rolling schedules. For substantial quantities the lead time generally does not exceed two to three weeks. Contact your local Fielders® office for further information.

Installation Guidelines: Button Punched (Concealed Fixed)

Step 1

Place first sheet down with the correct length into the gutter. Using the rib closing tool squash the female rib and place a top fixing clip over and fix to the purlin.

SHADOWLINE™ 305 NON-CYCLONIC Installation Guidelines: Button Punched (Concealed Fixed) Step 1 Figure SL IG NC 001

Figure SL IG NC 001

Step 2

Using the rib closing tool squeeze the male rib of the first sheet. Place top fixing clip over each squashed male rib and fix to purlin. This needs to be done to prevent the sheet from lifting in the wind before the barges are fitted. The use of string lines will assist in ensuring sheets are installed straight.

SHADOWLINE™ 305 NON-CYCLONIC Installation Guidelines: Button Punched (Concealed Fixed) Step 2 Figure SL IG NC 002

Figure SL IG NC 002

Step 3

Make a small non-permanent mark in the pan to enable you to locate the clips in the latter locking operation with the button punch.

Step 4

Position the female rib of the next sheet over the male rib and clips ensuring that it is fully engaged. Fully engage the sheet with the clips using foot pressure on the ribs over each clip. You can do this by walking along the full length of the sheet with one foot in the tray next to the overlapping rib and the other foot applying pressure to the top of the interlocking ribs at regular intervals.

SHADOWLINE™ 305 NON-CYCLONIC Installation Guidelines: Button Punched (Concealed Fixed) Step 4 Figure SL IG NC 003

Figure SL IG NC 003

Step 5

Repeat steps 3 to 5.

Step 6

All lapped ribs must be locked along their length, by button punching at the clips, and if necessary between the clips (typically at 900mm centre to centre). Punching to a string line guide stretched across the sheeting is recommended as random punching marks the appearance of the finished work.

Step 7

You must button punch through the hole in each top fixing clip, you can locate the clip with the non-permanent mark made previously. When operating the punching tool, stand on the pan of the overlapping sheet to ensure that the sheets are fully engaged.

Figure SL IG NC 004

Ends of Sheets

Wind can drive water uphill under the flashings or cappings. Also, at the low end of a roof, wind or capillary action can cause water to run back up the underside of the sheeting. To minimise these problems, turn the pans up at the top of sheets, and turn them down at the bottom. A tool is available for these jobs (ref. Figure SL IG NC 005).

SHADOWLINE™ 305 NON-CYCLONIC Ends of Sheets Figure SL IG NC 005

Figure SL IG NC 005

Turning-up

Flush turn-ups are usually used on Shadowline® 305. Cut off a portion of the female rib for at least 50mm. For a flush turn-up, you also need to cut the crown of the centre rib for at least 50mm.

Holding the end of the tool against the end of the sheet, pull the handle up 90°. If turning-up flush, fold the protruding ears flush against the turn-up tool with a rubber mallet (ref. Figure SL IG NC 005).

Turning-down

All roofing on slopes below 1 in 5 (10°) must be turned down. Turning-down is usually done after the sheeting is fixed on the roof, provided there is no obstruction to the operation of the turn-down tool.

Push the turn-down tool over the end of the tray, as far as it will go.

Hold the tool hard against the end of the tray and push the handle to form a turn-down of about 20° (Figure SL IG NC 006).

Insulation

Care needs to be taken when installing insulation with Shadowline® roof sheeting. When insulation thicknesses up to 50mm are installed the screws may need to be increased depending on the thickness and density of the insulation. When the screw is properly tightened into metal there should be a minimum of three (3) threads protruding past the support being fixed in to. For timber, the screw must have a minimum embedment of 25mm into timber.

When insulation is required in conjunction with Finesse® profiles, Fielders® recommend the use of a thermal spacer to help maintain Rw values as well as minimising any bulging in the profile caused by the insulation.

Insulation blankets and batts can cause wide flat pan cladding to bow out between the supports, between fasteners along the support, or bow the pans. For insulation blankets and batts as well as more dense glass wool and rock wool, and thicker insulation, spacers are recommended.
