This company invented the fantastic product ZIPTRAK a shade system better than all the others. The ZIPTRAK shades come in a range of differnt coloured tints and are a one handed system where you simply grab a hold of the middle and push-up similar to the rollerdoor on your garage. It is also possible to have these motorised and simply controlled with a remote. I love it! This system allows you to use your verandah or outdoor area all year around and you will wonder how you ever lived without your ZIPTRAK blinds.
