A: The recommended maximum for Ziptrak® blinds are: 4500mm wide by 3000mm high, or 4000mm wide by 3500mm high. An experienced installer can decide whether to exceed these measurement considering wind rate, skin material, operators, structure strength, etc. Smaller Ziptrak® blinds will look neater, and will be easier to operate.
A: Under certain conditions width can be extended to 5000mm. However we recommend that you divide the opening using either a fixed or removable post. The removable post offered by Ziptrak®, once removed, will not protrude into the opening more than the Ziptrak® blinds.
A: Ziptrak® blinds are designed with spring loading, which makes their operation simpler and easier than using a crank handle. Therefore, we do not recommend having Ziptrak® blinds operated with a crank handle.
A: Yes. Ziptrak® offers a fully enclosed pelmet; the Ziptrak® pelmet is made out of cast aluminium pelmet end plates, and the cover is made out of Colorbond sheet metal which can be ordered from a sheet metal fabricator in your area (drawings available). Roll-over pelmets can be used for Ziptrak® blinds as well, however, it will protect the roll from the top and front only.
A: Only Ziptrak® blinds with a solar screen, or woven material skin can be motorised, using 240V/AC tubular motor with obstacle detection feature. Strong wind can hold the skin of a Ziptrak® blind preventing it from sliding down the tracks, therefore, we recommend that motorised Ziptrak® blinds will be supervised by the operator while they are moving.
A: Flexible PVC used as skin for Ziptrak® blinds becomes stiff in cold weather, this stiffness make it difficult to slide down the Ziptrak® tracks because it tries to maintain its roll-up shape in the the top keyway tube. The PVC stiffness is not a problem with manually operated Ziptrak® blinds, but in a motorised Ziptrak® blind, the weighted bottom rail cannot always overcome the PVC’s stiffness.
A: We recommend to use 0.75mm thick clear or tinted PVC for Ziptrak® blinds. 1mm thick PVC can be used too, however, there is no advantage using 1mm thick PVC in our opinion, and with larger Ziptrak® blinds it can even be a disadvantage, because of the 1mm thick PVC is heavier.
A: Wind loading test on 2500mm wide by 2500mm high Ziptrak® blind with SunScreen, performed by the University of Adelaide yield the following findings:
A: Ziptrak® blinds were designed for vertical applications however, overhead openings of 2000mm wide and less can be covered with Ziptrak® blinds using light fabrics of about 250gsm. An overhead Ziptrak® blind should either be open or closed - we do not recommend you leave it midway.
