Klip-Lok 700 Hi-Strength®
KLIP-LOK 700 HI-STRENGTH® is a new generation of wide-cover, concealed-fixed cladding, suitable for commercial and industrial projects where long uninterrupted flat roofs are required.
It is called HI-STRENGTH because it spans further, with better uplift performance than all available comparable products. Suitable for all weather, including snow, it features a bold rib and flat pans which are cross micro-fluted.
KLIP-LOK 700 HI-STRENGTH® has a 700mm wide cover width and concealed fixing for clean lines and watertightness. It is suitable for installation over insulation up to 100mm thick, using clips fixed with conventional hex head screws.
Minimum recommended roof pitch is 1 degree (0.48mm BMT) or 2 degrees (0.42mm BMT).
Before starting work, ensure that the supports for your cladding are truly in the same plane and that the minimum roof slopes conform to our recommendations. The overhangs of sheets from the top and bottom supports must not exceed our recommendations.
Make any necessary adjustments before you start laying sheets, because they will be difficult to rectify later.
Where insulation is to be installed, you may need to increase the length of the screws given below, depending on the density and thickness of the insulation.
When the screw is properly tightened:
into metal: there should be at least three threads protruding past the support you are fixing to, but the Shankguard must not reach that support;
into timber: the screw must penetrate the timber by the same amount that the recommended screw would do if there were no insulation.
It is essential that the sheets interlock completely. It is important that your weight is fully on the sheet you are installing.
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 slightly out of parallel to gradually correct the error. (Figure 6) To allow this to happen, flatten the tabs on the base of subsequent clips—the slot in the clip will allow the clips to be fixed out of standard pitch.
If the final space is less than the full width of a sheet, you can cut a sheet along its length and shorten the clips as appropriate.
The installation procedure for walls is similar to that described for roofs. To prevent KLIP-LOK 700 HI-STRENGTH® from sliding downward in the fixing clips, you should pierce-fix through each sheet under the flashing or capping, along the top of the sheets.
