Exterior Steel Frame Glass Door Construction
Glass Divided Lites
Lites are the separate pieces of glass in a door. Lites can be truly divided, singular pieces or simulated divided. The division is achieved by mullions.
True Divided Lites(TDL): multiple separated pieces of glass divided by mullion lines that go in the glass.
Simulated Divided Lites (SDL): a single section of glass that has the appearance of division through applied mullions.
True Divided Lites - TDL

- True divided lites are easy to replace, repair and clean due to the individual nature
- Has more strength due to the stabilization from the mullions through the glass
- Width of 1-5/8" on the mullions
Simulated Divided Lites - SDL

- More affordable construction
- Has a similar separated design
- Can be used with more narrow mullions, down to 3/4"

FerroFinestra W75 TB
Ottostumm's newest system, W75 TB FerroFinestra, utilizes a palpable, visible insulating surface. This is our most advanced insulator in our steel door collection. The profile of this systems allows us to utilize insulating, low-E glass the increase thermal protection. This insulator is fiberglass-reinforced and provides superior insulating properties for the harshest of climates.
