Impact-Resistant Door Thresholds Approved for the High Velocity Hurricane Zone Requirements

Replacing existing swing doors for hurricane-rated, impact-resistant doors manufactured in Florida for the Florida weather conditions has its peculiarities.  For example, when installing a new impact door, the new door has to come with a threshold (the aluminium assembly part that goes on the bottom of the door frame) that is at least 1.5 inches in height.  For new construction projects, this might not be an issue since conditions can be worked out in advance to accommodate for the new threshold dimensions.  However, when working on existing properties on what we refer to as retrofit projects, then homeowners might find surprising how tall the new threshold is in comparison to the one being replaced for.  

For those potential client out there, we have created a short video with a 3D illustration featuring a scale-sized threshold for a PGT Industries's swing door, the Series FD101 French door. 

We hope you find this video useful.  If you are in the market for replacing your existing windows and doors for impact-resistant windows and doors, please call us at 305-328-9138 or visit us at
