Considering buying roll down hurricane shutters for your home in Florida? If so, you have probably seen the term “end retention” used. Some roll-downs have it, and some do not. But what does it mean, and what is the difference between roll-downs with end retention and ones without? That is what we will dive into in this short blog post.
What is end-retention for roll down shutters?
End retention (ER) is an option for roll shutters where each of the slats are engaged (or retained) in the rail housings. This system holds the slats securely in place during a hurricane. It also allows the shutters to be used without a storm bar (reinforcement) found on some roll shutter systems.
You can get roll-downs without this type of retention system. Those will instead use a storm bar for reinforcement.
One of the biggest benefits of the ER system is the ability to accomplish wide spans without storm bars. These shutters are hurricane-rated, impact resistant, and meet the Florida Building Code.
You can see a basic diagram of the system below:
