6100 | Single Hung Vinyl Window

6100 Single Hung Vinyl Window

The Comfort Series model 6100 single hung is a new generation window for Gerkin! After a decade of proven performance with our single hung, we found a way to make it even better! Here at Gerkin, we only make changes in our product to ensure better performance. Many competitors are working hard at seeing how cheap they can build a single hung. We believe our customers want a great value of quality and price. That’s why we build our windows to perform among the best in the industry. The 6500 window complements the 6100 single hung as a stand-alone fixed window or can be used to mull fixed and specialty shapes in order to create custom configurations.

The 6100 is highlighted by the use of a stylish 2 1/2" beveled frame design, fusion-welded sash and frame, and triple weather seals. We have designed this window to perform at a very high level through the use of multiple vinyl chambers, internal aluminum reinforcements, heavy-duty block and tackle balances, as well as warm edge technology glass! If you’re looking for a high performance single hung window with easy operation and low maintenance all at a great value, look no further than the Comfort Series 6100!

Multiple Seal Weatherstripping

Multiple Seal Weatherstripping: Triple fin-seal weatherstripping on the sash with additional weatherstripping at the interlock provides a tight air and water seal at the sash.


Interlock: The 6100 has a full interlock with fin seal weatherstripping at the meeting rail. Its design provides a positive seal and easy operating engagement.


Balance: The 6100 operates on a smooth operating block and tackle balance system.

Tilt Latches

Tilt Latches: The tilt latches are recessed into the sash for a more attractive appearance.

Aluminum Reinforced Sash

Aluminum Reinforced Sash: The sash is reinforced with extruded aluminum stiffeners around the full perimeter of the sash. The sash is also exterior glazed for a more attractive appearance on the interior.

Sloped Sill Design

Sloped Sill Design: Our single hung utilizes a fully sloped, weepless sill design. This provides for excellent drainage and air infiltration performance. Plus there are no weeps to get plugged!

Extruded Screen Frame

Extruded Screen Frame: Gerkin offers more strength in its screen frame in order to provide reliability and screen durability. The screen is removable without removing the sash.


Frame: 2 1/2" frame depth and a slimline design with exterior bevels provide strength and beauty. Our frame and sash are fully fusion-welded extruded UPVC.

The 6100 single hung comes with 3/4" insulated clear or argon filled LoÉ3 high performance glass. Double LoÉ or laminate glass options are also available.
