Weathertight Folding Door Systems

Weathertight Folding Doors are available in two versions:

Standard – DP35 Rated using 1 ¾” doors and Low E Insulated Glass

Impact – DP55 Rated for Hurricane zones uses larger hardware, 2 ¼” Doors and Low E Insulated Impact glass.

Both have Florida Building Code and Texas Dept. of Insurance approval.  See the Engineering page for information and test reports.

Weathertight Folding Doors are complete ready to install systems.  They include your choice of door style, hardware finish, frame options and thresholds.  See System Design for these options.  The clearly labeled system along with detailed instructions allows skilled carpenters to install these in just one day. 

We make bi-folding systems for a wide range of both residential and commercial applications.  The Configuration Page shows our standard sizes but we can customize most systems to fit any opening.

We also have the experience to tackle the most challenging jobs such as curved folding door walls and open corner folding door walls.
