In windy conditions, Ziptrak blinds should be left down and locked, or fully retracted – half way is the most vulnerable position. During severe weather events, your blinds should be fully retracted.   You may find Ziptrak spring-balanced blinds are a little tricky to operate during windy conditions due to the pressure of the wind on the blind material. Use your hand to push against the blind material to reduce this pressure and then operate the blind.   Care must be taken when operating motorized Ziptrak blinds in windy conditions. They must be supervised whilst raising and lowering at all times.   If the fabric blows out of the channels during windy conditions we are happy to do a service call to fix up but it is not covered by the products warranty and will be chargeable
