Gerkin subframe is a thermally broken receptor system that is designed to make window installation quick, easy and 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 snap 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 which gives 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:
- The complete installation can be done from the interior of the building eliminating expensive lifts and bulky, hard to work with scaffolding.
- Subframe helps to speed up the installation on multiple window configuration
- All fasteners are hidden.
