The 38 Drain, featuring our most desirable hidden and flush sill, is available for all hurricane projects.  With successful Dade County testing up to a design pressure of 70 (DP70), this door is approved for South Florida oceanfront projects. 


OTIIMA USA currently stands alone in the market of invisible sills tested and approved for Dade County.  Achieving the DP70 requires 10.65 PSF water pressure to the system, proving a truly amazing accomplishment. 


There are three interlock options for this door; one option with a heavy duty interlock at 30 mm and two options with the standard 20 mm slim sight line. Structurally, this door reached cycles at 105 PSF. 


The glass we use for the hurricane doors consists of a Low E tempered exterior sheet with a laminated interior pane and heat strengthened or annealed to provide amazing clarity while still holding up to the projectile objects during a hurricane. 


The sentryGlas interlayer used in our laminated unit is 5x stronger and up to 100x more rigid than conventional laminating materials than the normal PVB interlayer found in other laminated glass.
