Modern manufacturers have improved their designs of jalousie windows to address these problems. Many market their products as having greater security and energy efficiency compared to earlier versions. The Australian company Breezeway, which began producing jalousie windows in 1935, is currently marketing jalousies which they claim creates an airtight seal when closed to keep out water and insects while keeping in air conditioned air. Breezeway brand jalousies are made with non-corrosive hardware and a pinning system which keeps the slats secured from the interior of the house to increase security and prevent the slats from falling out. They are currently the only jalousie window in the United States certified to withstand a Category 5 Hurricane.
