The Gerkin 5300 casement window is designed with performance in mind. The air infiltration on our casement is often better than our competitors’ fixed windows. These windows perform so well in NFRC thermal tests that they have been used in 5-Star Green Building projects, Net Zero housing and numerous LEED certified projects. Some of the highlighted features of the casement includes compression bulb weather seals, multi-point locking, easy to crank roto system, heavy-duty stainless steel hinges, and hydraulically-locked sash corners keys with liquid welds.
Our attention to detail in design and workmanship has earned Gerkin a reputation for building quality windows that withstand the test of time and have earned Gerkin the Builders Choice Award.

Rated Casement Window: AAMA CW40, CW60 and CW90 rated casements. |
 |
2 3/8" Thermally Broken Frame Depth: We use double wall construction and a thermally broken frame and sash for improved thermal efficiency. |
 |
Reinforced Power Crimped Sash Corners: All sash corners are reinforced with two engineered corner keys which are hydraulically crimped, creating a corner built to last for years of trouble free operation. |
 |
Sash Overlaps Frame: We provide two compression seals on every sash and then overlap the frame of the window with one of the seals. This design allows us to have one of the tightest windows available. |
 |
4-bar Friction Hinge: These heavy-duty hinges will provide easy operation and tension adjustments. Washable and egress hinges are available for roto operation or push/pull manual operation. |
 |
Truth Maxim Roto Operators: We have eliminated the complaints of hard operating casements by offering extra cranking power and a low gear for smooth, trouble-free operation. Our gear teeth are close together, which removes extra play in an open sash and reduces the likelihood of damage. |
Truth Maxim Multi-Point Progressive Lock: This 3-point lock system is very forgiving with a wide operating tolerance. Secondary locks are no longer needed. The weather seal received from the system is incredibly tight. |
Insulated Glass: Overall glass thickness options is 1". We offer several stocked glass options as well as numerous special order options. |
Extruded Screen Frames: We use extrusions on all Rhino screen frames instead of lightweight roll form aluminum. Extruded screens are much more durable and save money in replacement costs. |
Rhino Accessory Options: We offer complete sub-frame and panning systems, nail fins, snap trims, sill-flashing, strap anchors, stacking frames, structural mullions, mullion covers, and factory applied extension jambs. |
Other Options: We offer a louver system with a blank-off panel for PTAC units. Casements are available in vertical or horizontal multi-window configurations. |
