2 3/8" Subframe
4 5/16" Subframe
Our subframe is a thermally broken receptor system that is designed to make window installation quick and easy. It can be used in both new construction and retrofit applications. The sub sill is a one-piece receptor with an exterior weep system to channel the moisture to the exterior and extruded legs to trap the window into place. The subhead and jambs are a two-piece receptor with a vinyl bulb on the interior and exterior legs, which snaps into place and gives the window a snug fit into the opening. When using the subframe, there will be a 1/2" space on the head and jambs allowing the window room for thermal expansion and contraction. The subframe is color matched to the Rhino windows, giving the opening a one-piece finished look. The subframe can be used in a one-window opening or multiple window configurations. Gerkin's structural mullion, h-channel, and stacking frame options gives the end user many different configurations to choose from. Gerkin also has an extruded sill flashing available giving a complete window system.
Some of the advantages of using the Gerkin subframe system are:
Our panning is designed to cover existing window frames for jobs when tear out is too costly or cannot be done. The panning has 3 7/8" legs on the exterior that can be field ripped to cover many conditions, giving you the look of a new window system without the headache of tearing out the old window frames. The panning has a sloped sill, ensuring that the moisture drains away from the opening. The jambs and head have a vinyl bulb on the exterior leg for ease of installations. Gerkin supplies interior clips that fasten to the window and the condition, trapping the window to the panning system. The panning is color matched to the Rhino windows which gives the opening a one-piece finished look. The panning can be used in a one-window opening or multiple window configurations with the use of Gerkin's structural mullion, h-channel, and stacking frame options, giving the end user many different configurations to choose from. Gerkin also has an optional 1"x 3" interior snap-trim to cover up the interior condition.
Some of the advantages of using the Gerkin panning system are:
All Rhino windows can be field stacked together using an integral stacking frame. (Sliders and single hungs require H channels for side stacking.) Windows can be stacked at the head, sill, and jambs, which allows for the creation of many window configurations.
This accessory is used for side stacking single hungs and sliders together in the field. The H channel can be used for single hung sizes up to 48" x 72" and slider sizes up to 72" x 72".
This accessory provides additional support in large rough openings that have multiple window configurations. The structural mullion is used vertically between windows to provide structure and can be anchored to the head and sill of a rough opening prior to installing the windows.
2 3/8" Structural Stack
4 5/16" Structural Stack
This accessory provides additional support in larger rough openings that have multiple window configurations. The structural stack can be used both horizontally and vertically between windows to provide structural support. The structural stack is applied after the first window is installed and before the second window is installed.
We offer an optional sill flashing that can be used either directly under the Rhino window or in conjunction with the subframe system. This flashing is extruded aluminum and extends 2 5/8" beyond the front of the window.
Rhino hopper, awning, casement, and fixed windows can be anchored into masonry conditions and extend over conditions such as expansion joints where anchoring by traditional methods is not possible. The strap anchor allows the window anchor to be located up to 1 1/2" behind the window.
We can glaze 1" louvers into our window system for PTAC units. When louvers are used with windows, one rough opening can be created instead of two. (The window is stacked on top of the louver frame.) This saves framing time and materials and gives a total matching system. Gerkin can provide a blank off panel with appropriate cutouts to receive the PTAC unit.
