Steel Casement Window

These exterior steel single double casement windows are pre-hung and include both the window and fully assembled frame. The jamb size is measured at 1.5” deep (net size) and made from Ottostumm hot rolled solid steel.

Please note that, for weather sealing purposes, all casement windows are made as outswing units, meaning the operable panel will swing to the outside of your home.

These exterior steel double casement windows feature a welded drip edge directly above the operable window panels. This drip edge serves as an additional barrier, preventing descending exterior elements from entering your space between the frame and operable panel itself, while still allowing the casement window to operate without obstruction.

These exterior steel double casement windows come standard with modern bullet hinges. The frame will have the bottom portion of the hinges welded on (Hinge and male pin). The top receiving portion of the hinge will be welded onto each window leaf, and include a screwed in grease fitting, allowing you to maintain and grease the hinges regularly via a standard grease gun. 

One copper crush washer per hinge is included and required prior to hanging the window onto the frame. These washers protect the hinges by introducing a softer copper metal between the 2 hinge components in order to absorb the friction and allow the doors to swing smoothly. This hinge system is far superior to ball bearing systems, as the bearings are made of stainless steel, which is a harder metal inside a steel barrel, causing wear to both components and sagging over time.

Each of these exterior steel double casement windows include both the locking handles as well as the window stays, which work in conjunction to operate your casement windows.

The locking handles include brass wedges attached to the frame of the window in which the handle will lock onto. The window stays are attached to the bottom of the windows and include  butterfly thumb turns to secure the stays and windows in their desired position.

Please note, double casement windows taller than 48” will include single handles that operate multiple locking points along the frame.

These exterior steel double casement windows are equipped with flush bolts installed on both the top and bottom of the inactive dummy leaf window. When engaged, these flush bolts will secure the dummy leaf window into the frame. Disengaging these bolts allows for the inactive window panel to open, creating a more generous opening.

These steel exterior double casement windows come standard with pre-installed weather stripping around the entire perimeter of the casement window panels as well as the frame. This creates a full seal and acts as a barrier from outdoor elements, helping to prevent cold or hot air from leaking out of the home, resulting in a much more energy efficient product.

These steel exterior double casement windows feature a welded 2.2” nailer fin around the frame of the window, and is designed to be installed from the exterior of your space. This nailer fin is inset to allow for a 1/2” of finish work on the exterior of your home, and includes pre-drilled holes around the entire face of the fin.

Steel windows offer many more enhanced security features when compared to their wood, fiberglass, vinyl, or aluminum counterparts. These steel exterior double casement windows are made with Ottostumm hot rolled solid steel, drawing inspiration from 20th century design characteristics, with a modern twist. Ottostumm materials are known for their durability and sleek profile, allowing for a wide range of creativity that works in any application. This slim jamb size of 1.5” allows for a ultra thin, modern aesthetic.

How thick are your exterior steel double casement window jambs? 

These exterior steel double casement window jambs come standard at 1.5” thick.

Is the jamb the same thing as the frame? 

The jamb refers to the vertical components of the overall door frame. The jamb size refers to the thickness of those vertical components.

How does the frame mount to the wall? 

These steel exterior double casement windows feature a welded 2.2” nailer fin around the frame of the window, and is designed to be installed from the exterior of your space. This nailer fin is inset to allow for a 1/2” of finish work on the exterior of your home, and includes pre-drilled holes around the entire face of the fin.

Is the jamb included with the window?

Yes, the jamb is a component of the frame, which is made specifically for the window that it is packaged with.

Is the jamb/frame galvanized or zinc coated?

Yes, these exterior steel double casement window jambs and frames are galvanized dipped before the doors go into their paint process. This galvanization helps prevent finish issues when exposed to damp or moist conditions.
